My daughter was driving on the interstate when the car went into limp mode and the engine light was flashing. We had it towed to hyundia dealership where they did an engine update. Had it for 3 months when it did the same thing to her again. Had it towed again to same dealership where they are telling me it needs a new engine.

When auto lights are engaged and the blinkers are engaged, the light will turn off and it will blink in the wrong direction for a few times and then blink the correct direction. While in auto lights and you turn a curve they will sometimes go off. Now I have an issue with my AC - it goes on and off randomly. Had it looked at and they cannot find an issue with the components but said it could be an electrical issue. BYW, Hyundai replaced the motor in this car as well because it had so many issues. I was told the issues now could be caused from them replacing the motor and causing an electrical issue. The paint is also peeling and they had a recall on the paint, but the paint on my car didn't start peeling until after their warranty had expired. This is a known issue with 2015 models - they know the paint is bad but won't fix it. Car manufacturers should be held accountable for what they put on the market, or at least fix what are known issues for multiple vehicles.

The contact's son owns a 2015 Hyundai Sonata. The contact stated while her son was driving approximately 45 MPH, the sunroof detached and landed on the road. The contact stated no warning light was illuminated. The driver retrieved the sunroof and placed it in the trunk of the vehicle. The contact took the vehicle to the local dealer, where it was diagnosed with needing the panoramic roof to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 16V726000 (Visibility) however, the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 70,000.

My car was a 2015 Hyundai Sonata that was stolen off a well lit street in Milwaukee two days ago. The car was locked with the alarm activated. I feel violated and my safety was at risk and the company knows about the safety issues of these cars and have done nothing about it.

2 recalls were found on my car and a service campaign. After taking my car to a couple auto shops, within 2 years my car has had the same repair issue involving P010 & P011 codes. After researching and finding there was a service campaign and 2 recalls, I decided to take my car to the dealership due to address the recalls. I took my car in on 8/1 and had a full inspection done on my car. Outside of the normal wear & tear, I was advised that the ECVVT cap was installed incorrectly, that it was leaking oil. I was told that cleaning the oil & reinstalling the cap would correct the problem, it didn’t and I’m out of additional money ($562) and the problem is reoccurring. I’ve called several times recently, as well as one of my mechanics, hadn’t received a return call not until I filed a BBB complaint. It seems they are not honoring or even considering the service campaign (ECVVT Seating issue) and it is my belief, will continue to send me in circles to pay more money. A full inspection was done on my car, wasn’t nothing major but my engine light came back on in route home. I called the advisor and he couldn’t give me a definitive response as to when I could bring my car back & get it checked again. I wanted another appointment time so that I wouldn’t be inconvenienced by sitting at the dealership all day until they decided to check or get to my car again. It took me almost a month to get the 8/1/22 appointment. The staff I spoke with has tried to convince me that the issue with my car has nothing to do with the recalls or the ECVVT service campaign, I disagree especially experiencing the repeated P010 & P011 codes. One of the recalls also was for the ECM.

The contact owns a 2015 Hyundai Sonata. The contact stated that after her vehicle received an oil change by an independent mechanic; she was informed that the vehicle was consuming an excessive amount of engine oil. The mechanic informed her to monitor the oil consumption. The contact stated that upon starting the vehicle, an abnormal knocking noise was coming from the engine, with the check engine warning light illuminated. The vehicle was towed to a local dealer who had previously informed the contact that any damage done to the engine would be covered under a class action lawsuit. The contact submitted two claims to the manufacturer for an engine replacement; however, both claims were denied. The vehicle was not repaired. The failure mileage was approximately 130,000.

Power steering stopped working. 2 icons came up on instrument panel. A red steering wheel with an exclamation point and a car skidding. I was making a turn and was unable to turn the car back straight. Luckily I was going slow and was able to get stopped. I was able to get the car home without power steering. After restarting the car the power steering came back. Now I can't trust the car.

The engine stalls out randomly. This is the third time it's done it. The first time was while I was exiting the freeway on March of 2021, which I thought was a fluke. The second time was July 19th and the third time was July 30th. There were NO warning lights or messages. Took it to the dealer and they said that everything came back fine with the engine. They confirmed that the RPMs were too high when it was in a parked position and the engine was on when they first took it in. They suggested I replace the starter. I'm going to a different mechanic for a second opinion. The car was in motion with my foot on the gas pedal when it started to stall. There is no way that it is from a starter.

The contact's husband owns a 2015 Hyundai Sonata. The contact stated that while her husband was driving at an undisclosed speed, the vehicle lost motive power. The vehicle was towed to the residence, where it was diagnosed by an independent mechanic with engine failure. The mechanic informed the contact that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

The issue is with the hybrid system, which malfunctioned and apparently ruined the rest of the car. The damaged components are adding up to over 75% of the car's value. The vehicle slowed and stopped suddenly on a busy road when the issue started. Currently, it has been inspected by two different shops and they have both given me the same diagnosis.

It happened with me twice when I noticed that after about 1800 miles after my car’s oil change, the oil light comes up when there’s a turn or a speed bump. After checking the dipstick, I noticed that there was no oil in the engine. I got it checked for some possible leaks in the car but there were none. This narrowed it down to the cause that the car is burning oil too quickly and that it could also lead to to engine seizure if on a long drive. I also did some research on the same and found that I wasn’t the only one and that there still hasn’t been a recall on the same. I believe it is a safety issue if the engine malfunctions while driving, be it long range or a short one.

After taking my car in multiple times to be serviced for a "Hybrid System Warning" mid last year, they were unable to read any error codes or diagnose any issue. I took it to two separate dealerships with no luck fixing the issue. I then completely broke down due to the same "Hybrid System Warning" on the highway on 7/26/22 heading to Pigeon Forge, TN with two children in the car. I had to have my car towed to the closest Hyundai dealership in Knoxville. They were unable to diagnose and fix my car within the timeframe I was in town. Since Hyundai would not provide me with a loaner, I had to get a rental car to get home that I was not reimbursed for. We ended up paying out of pocket to replace the safety plug/fuse and the power relay assembly on 8/9/22. After having the car back for three months, the warning popped up again on 10/18/22 just as it did earlier that same year. I immediately called to schedule a service appointment with Hyundai and had to wait almost four months to get a service appointment here in Cincinnati. The appointment was on 1/26/23 and they have yet to "replicate the issue" so they are unable to diagnose the car. I am supposed to pick up the car this week even though it's a safety hazard. I have had two cases open with Hyundai Customer Affairs but since they cannot diagnose the car, there is nothing they can do. They have been absolutely no help at all.

Driving at 55 and the engine blew. No warning, no check engine light, no sign of anything wrong. Power steering loss, limo mode activation. Almost rear ended during catastrophic failure. 111,000 miles

The contact owned a 2015 Hyundai Sonata. The contact stated that while driving at various speeds, the vehicle was shaking uncontrollably and stalled. The accelerator pedal was depressed but the vehicle failed to move. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic and the contact was informed that the failure was due to the engine. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 140,203.

My ABS lights came on and then minutes later my check engine light kept blinking while my car kept stalling or not let me accelerate in the middle of traffic. It’s like the engine dies but the car is on. It only stalls for a second then accelerates then stalls again and accelerates. Almost caused an accident. Seems that this is a problem for a lot of these models. It’s just crazy how it all happened back to back. My car has been running fine otherwise till that happened.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 45 MPH, there was a cranking noise coming from the engine. There was an engine overheated message displayed. The vehicle was towed to the local dealer. The dealer diagnosed the vehicle with engine failure. The vehicle was then towed to another dealer who diagnosed the vehicle with engine failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 127,785.

Vehicle suddenly lost power while in operation. Vehicle was in motion approaching an intersection. When left turn indicator was activated, all lights on the instrument panel illuminated, the engine shut off, and power steering was lost all while the Vehicle was in motion approaching a intersection with stop sign. Vehicle was able to stop before entering the intersection, but would not start again and we were stranded in the middle of the road. Electrical systems appeared to be working. Battery and alternator are functioning normally. After Vehicle sat for 20min, it then was able to start and moved out of the road to a safe location. Vehicle was towed to mechanic that confirmed Battery health and alternator functioning. Vehicle was then taken to dealership for recall 210 safety repair. Dealership service unable to determine cause for loss of power while Vehicle in operation. No explanation, offer of additional service, or remedy has been offered despite requests. I do not feel it is safe to operate this vehicle in the absence of information related to the sudden loss of power during normal operation. Had this occurred in another setting with more traffic or less room for safely coasting to a stop, serious injury or worse could have resulted. The vehicle is still eligible for the 10yr 100k mile powertrain warranty and I am the original owner. We do not feel we can safely operate this vehicle and need guidance on how to proceed with pursuing a remedy to the situation from the vehicle manufacturer.

Multiple times, when the car start up and is put in to reverse, there is no throttle response. Simultaneously, it can not be put into the manual gear select mode and the car lurches into second gear.

We had taken out 2015 Hyundai Sonata to the repair shop because the check engine light came on. The repair shop said it gave the error for low oil, but the oil in the system was not low and we were barely past the oil change mileage. We had the oil changed and picked the car up. The next day, the car lost all power and locked up completely while going about 45 mph down the highway. We had to push the car off the highway. Car was towed to same repair shop and we were informed the motor was blown. We called Hyundai but they offered no assistance since we were past 100,000 miles. The engine blew at 114,000 miles.

The panoramic sunroof wind deflector is off I seen online there was a recall about that. I call hyundai customer service about it they said it's been fix already in 2016. I'm a new owner and not sure where the work was done before I got it, but it came unglued again. I purchased the car from John amato hyundai dealership and get the services done there because I'm under a forever warranty and can't going anywhere eles because of the warranty. Which nothing is done free on it and all the work I've had done from them I believe they don't do everything because it still rides and sounds the same and there #1 excuse is that's how hyundai cars sounds. So with that being said if John amato fixed it, I see why it failed again. Can check my car to see if recalls were really preformed and done correctly and what's needed now to be like new again.

The top of the low pressure fuel pump in the fuel tank was cracked. A strong fuel smell was present near the rear of the vehicle. When the vehicle was placed on jack stands, leaking fuel was visible on the sides of the fuel tank. The rear seat was removed, fuel pump access cover was removed, ignition was turned on and fuel was observed leaking from cracks on the top of the low pressure fuel pump. This is a huge safety concern due to fuel leaking from the fuel tank. I know for a fact this is not an isolated incident, you can watch YouTube videos of others with the exact same problem. The dealers want $1K+ to repair. I was an ASE Certified mechanic for 20+ years experience, I purchased an OEM fuel pump through an online retailer for ~$600 and replaced it myself. Problem solved, but for how long? There were no warning lamps or messages, the only sign was the strong smell of fuel.

Engine had knocking then completely froze while driving due to low oil pressure. Car has been well maintained, regular oil changes and just had axle repaired. Hyundai has extended warranty to cover this issue that is common on these vehicles and should cover the cost of the new motor. Consumer spoke with Hyundai corporate and the case number is [XXX]. Although they are well aware of cars catching fire and are even part of a major litigation lawsuit for this same situation consumer is getting nowhere with them. Consumer's daughter could have been seriously hurt in this incident. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”

The contact owns a 2015 Hyundai Sonata. The contact stated while attempting to start the vehicle, he noticed that the sunroof was inoperable. The contact stated there were no warning lights illuminated. The vehicle was taken to a local dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was notified of a failure. The contact related the failure to NHTSA Campaign Number: 16V726000 (Visibility). The approximate failure mileage was 83,000.

My Car is burning engine oil at in alarming rate. I put 5 quarts of oil in and my check engine light began to blink and my car would accelerate more pass 50 mph. So in 6 days and 578 miles; my car had less than a half of a quart of oil in it. My car is having engine trouble. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The vehicle is slow to accelerate and as its accelerating it often will jerk or hesitate roughly. There have also been times when accelerating, such as getting on a highway, that the whole (what I assume to be) throttle system will almost stop and it feels like the car is just going to stop right there on the highway. It's very dangerous as cars behind me are also accelerating and not expecting my vehicle to just stop. The vehicle is available for inspection. There are no warning lights, messages, or symptoms prior to the issue. It has not been inspected by anyone yet.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the vehicle hesitated during acceleration and lost motive power with several unknown warning lights illuminated. The vehicle was towed to the dealer where it was diagnosed with engine failure. The dealer informed the contact that the engine needed to be replaced; however, the dealer declined the engine replacement due to the previous owner's failure to have the Manufacturer Service Campaign Number: 953 (ECM & Cluster Update - Engine Monitoring Logic Product Improvement) performed prior to the failure. The vehicle was not repaired and remained at the dealer. The manufacturer was not made aware of the failure. The failure mileage was 124,803.

While driving on the interstate, the car began to jerk, and then the engine proceeded to rev as if the car needed a power boost to continue performing. The dashboard then said "Hybrid System Warning! Stop and Do Not Drive" and then the car would no longer accelerate and I had to pull over. This was an extremely dangerous and unsafe situation to be in, and unfortunately, the error only presents itself while driving so the mechanics are unable to get a code that clearly defines the issue that needs to be resolved. I have spent numerous hours on forums with complaints from Hyundai Sonata Hybrid owners who had the same issue and have visited various mechanics to fix the issue, only to end up having the issue arise yet again, further endangering their lives on the road. I believe the best solution forward is to take a serious investigation into the issue and issue an open recall so drivers can get the assistance they need to remain safe on the roads.

The car keeps throwing a code and going into limp mode. For the knock sensor. It was replaced less than a year ago and it is now throwing the same code. And once again in limp mode. The first time this happened was around 10/15/2021,&now today 6/17/2022

The contact owns a 2015 Hyundai Sonata. The contact stated while driving 45 MPH, there was a knocking sound coming from the vehicle with the check engine warning light illuminated before the vehicle lost motive power and stalled. The contact pulled over and waited until the vehicle cool down and was able to restart the vehicle, but the failure reoccurred. The vehicle was towed to the dealer and the contact was informed that the spark plugs needed to be replaced. The spark plugs were replaced; however, the failure reoccurred. The dealer informed the contact that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and stated that the warranty had expired and offered no further assistance. The failure mileage was 183,096. The contact noted that they are the second owner of the vehicle. Also, the vehicle had never been serviced prior to taking it to a dealer to fix the knocking sound.

My vehicle has an oil consumption problem despite the fact that my car has been excluded from the class action lawsuit. I’ve had it in the shop and they have confirmed the oil consumption issues. There are countless other vehicles excluded from the class action lawsuit that have the same theta engine as the other vehicles that were included in the lawsuit. This needs to be investigated. I still owe over 6k on my car and it’s one trip away from being completely undriveable

The vehicle is used as a commuter car, and driven primarily on NJ Turnpike at high speed. Over a two month period, on four occasions, the engine has shut off. All dash lights came on, and all power assist controls failed. Managed to get to shoulder of road, and after a few minutes, car would restart and run properly. The fourth time it happened, as I coasted onto shoulder, the car restarted by itself. Took car to dealer for diagnosis and repair and was told there were no codes and it "could be" any number of parts not working properly, but no actual diagnosis. Was charged $160 dollars, and I took vehicle home. But when I looked over the invoice, I found the description of problem was not what I had told service rep, so went back to talk to service manager. He told me to bring it back in and he would have it rechecked. Was told they drove car 35 miles a day but it never stalled. However, invoice shows same mileage went brought in and sent out. Again, they said they could find no codes, so they could not diagnose any problem. I went and picked vehicle up, but I drove through the dealer's parking lot to leave, I saw the engine service light was now illuminated, and returned the car to the service department. Was told they would check it out, and I went home. After three weeks, I called to find out status of car. Was informed they had yet to look at it, but would do so shortly. A week later I was told problem was a bad VCM Motor Assembly, and I was charged 788.70 dollars, to replace a part that apparently fine, when I dropped the vehicle off. Read numerous posts online by owners reporting this same engine shutting-off problem, since 2016. But no one has stated a definitive cause, or repair, by dealers. As to whether that was the cause of the engine shutting off, I will have to see.

Sensors lights would indicate an issue and would disappear sometimes without any reason (mainly Check Engine and Tire Pressure Sensors). Indicators would trigger the opposite direction (indicate right and the left indicator would turn on). Burning more fuel than expected. Primary fuel pump stopped working resulting in car stopping in the middle of the road.

Anytime the car needs a repair on something (fuel pump, inhibitor switch, etc.) in the middle of driving the car will flash "hybrid system warning safely stop and do not drive" and then either slow to 40mph then die, or just die completely. This has happened 3 times before I took it in to be fixed. A few months later, it happens again. It doesn't matter what is wrong with the car, the car just senses an issue and dies in the middle of driving. Very unsafe!

While driving POV from work, I began smelling fuel in the air conditioning system from external intake. Upon further discovery, the high pressure fuel pump was found to be dislodged from the engine, due to a sheered bolt. This allowed fuel to spill out on the manifold and engine, also reducing power for acceleration. This issue could have caused a vehicle fire that could have engulfed the cabin if ignited.

Faulty motor. No warning lamps or any other symptoms prior motor failure. At 123,310 miles motor spun lower camshaft bearing cause motor to lock up on a busy highway. Same as the 2013's & 2014's.

ABS and Traction Control warning lights came on, then went out the next time I started the vehicle. They then did this a second time. On the third time, they stayed on. Brakes worked fine, and vehicle had plenty of brake fluid. Inspection at dealership revealed left rear wheel speed sensor malfunction. Research discovered that this could cause a braking problem as the issue continued. Dealership verified this is a possibility. Dealership also stated they have had a number of vehicles report this issue; doesn't seem to be related to any particular year.

I had closed from work one morning and was headed home. Just a few seconds after taking off, my engine completely shut down. Thank goodness I wasn't in on a highway or at a heavy traffic area. I managed to park my car by the road side & tried to restart my engine, but the car wouldn't start. I towed the car to the nearest mechanic, only to hear that my engine is done & needs replacement. I've constantly kept up with frequent oil changes & always used synthetic oil. Current odometer reading is 153k & I believe the car still has the potential to stay on the road a longer time if the engine is taken care of. I've reported the issue to my nearest Hyundai dealership & they've asked me to tow it to them, but they can't promise that they'll take care of the problem. Worst of all, that's the only car I have & I'm still making payment on the car.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving 65 MPH, the vehicle began to shake and then stalled without warning. Due to the failure, the vehicle was towed to a dealer where the mechanic discovered that the spark plugs had disintegrated causing the piston rings to be damaged. The vehicle was diagnosed with engine failure. The manufacturer had yet to be notified of the failure. The vehicle was not repaired. The failure mileage was approximately 162,000.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 40 MPH, the vehicle was stalling with the check engine warning light illuminated. The vehicle was taken to an independent mechanic and diagnosed with engine failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 75,000.

When driving my 2015 Hyundai Sonata Hybrid, it will randomly start flashing and beeping at me with the saying "check brakes" Also my ABS Brake light comes on. This function only happens at random causing me to shut off my car completely and restart. It has really become a problem after I reached 112000 miles on the vehicle. I bought the vehicle with 80,000 miles. Anyone driving in my car is put at risk due to brakes not working accurately and are spongy feeling when pressed down. If I were to have to slam on brakes, I would ultimately run into another vehicle or object since the braking system during this issue does not work correctly. I have called the dealership to ask about the recall. No recall on this issue but online, similar issues have been documented.

I was driving on I 205 N (Portland, OR), at a speed of around 65 MPH, when I hear a loud pop. Wasn't sure what happened, and first thing I thought was that somebody fired at my car... I realized that the air entering the car was coming from the sunroof area, and hearing the sound of shattered glass moving on the piece of material that separates the sunroof from the interior I realized that the problem comes from there. So I got out at the next exit, stopped in a WINCO parking lot and started assessing the damage and cleaning/ vacuuming the glass.

Was diving the car and experienced system failure, no prior warnings or issues. Had regular oil changes throughout, however, a few days ago in normal driving conditions, the check engine light began flashing and car felt like it was losing power. Had to pull over to the side of the road and shut the car down. Vehicle would not restart and had to have the vehicle towed to the nearest dealer. Dealer informed us that the "engine was locked" and had to be replaced, car only has 62K miles on it. Research online has uncovered others that have had the same experience and issue with the 2015 sonata that has resulted in replacement of the entire engine. Dealer has not confirmed if repairs will be covered, but if we had been in a high traffic area the car losing power suddenly without warning could have resulted in serious injury getting the car out of fast paced traffic. There appears to be an known issue, as when we asked the dealer about others on-line who have had this happen, dealers response was "we have seen this before, yes." But, now we have been close to a week without a car, no loaner from the dealer, and no indication on how this will be fixed.

Major oil consumption going on for years. Took in to dealer two years ago, they know there is a problem. They told me I could spend thousands of dollars to tear it apart to find out what is going on, and also told me to call corporate. I got no where with either, even though they recalled the engine in other Sonata cars, just not our ECO model. Slowly started having throttle issues at 4 to 5 year mark. Informed dealer service center that it wasn't moving like it should when gas was pressed. Now, the car is having major problems with acceleration. Barely would go in reverse, drove 1.5 blocks, speed not matching to throttle, press on gas, barely moving from a stop, going really slow, had to turn around and take back home. Our problem with the car is the same that others are complaining about. The car is not safe for a 7 year old car that started having problems at the 4 to 5 year mark.

Was driving with cruise control on and driving close to 70mph and the RPMs shot up passed 5 then the car jerked and my speed had went from 70 down to 50 and 40 the cruise controle turned off on its own and the car lost power but was still on but it just wouldn't drive passed 2 rpms and the check engine light was flashing so I turned around and headed the opposite direction so I could get the car off the road then it made this loud noise sounded like throwing metal inside a metal bladed fan and then the car shut off and hasn't started since. The car did not over heat or have any smoke coming from it.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 70 MPH, the panoramic sunroof detached from the roof of the vehicle. The vehicle was taken to the local dealer who diagnosed that the wind defector bonding had failed to cause the failure. The contact was informed that the sunroof and assembly needed to be replaced. The vehicle was not yet repaired. The contact was informed that the VIN was not included in NHTSA Campaign Number: 16V726000 (Visibility). The contact indicated that the vehicle had experienced the failure listed in the recall. The failure mileage was 52,000.

I was driving on the expressway. After about 18 miles the vehicle slowly decelerated to a stop. I was able to safely exit the expressway to the side street. I turned the car off for a few minutes. It started back up but has not accelerated pass 20/25 miles. There’s also major oil consumption. Camshaft position & ccv issues yearly requiring sensors to be replaced. Increased gas consumption. There’s also been a humming sound coming from the car that’s not been able to be diagnosed by any mechanics.

The powered driver seat returning from a reclined position can get stuck in the recline position for some unknown reason. The seat motor, electrical wiring system and the switch have all been examined and replaced and yet for some unknown reason it continues to occur. Two different mechanics thought it was the switch for the seat being faulty but its been replaced twice and still this issue can occur where the seat after reclining any amount the seat will remain in that recline position for an extended period of time (multiple days) and can if reclined completely, remain in the full reclined position unable to return in the direction so as to raise it to a normal seated position. The seat switch will only recline but will not return back to the seated position to any degree. All of the other swithces and buttons with the drivers side seat continue to remain operational and work even when the seated position direction does not function. To operate a vehicle in the fully reclined position is dangerous as you have no back support while driving, there is also no whiplash protection or support in the event of a collision. It can also impair the drivers ability to reach the pedals or operate the vehicle properly. It also makes the seat behind the driver unusable. Further adding to the danger the seat has no manual options and therefore is unable to be manually returned to the seated position, thus once it is reclined back it remains stuck in that position until the switch begins to function again or the seat is removed. There are no warning lamps or indicators and the seat continues to properly function in the recline direction. Only upon trying to return to a seated position is there any indication of an issue. This has happened at least 3 times in the past year. Repair shops have examined the electrical wiring and the switch and cant seem to keep it from happening
