2023 Hyundai Santa Fe Complaint Log

On Saturday Morning (August 9th), I was driving this car with my family on I-495 heading to the shopping mall. The SunRoof glass broke suddenly without any impact from outside. I was so alarmed and exited the road and checked it. There was a crack in the front side glass. I drove back home and found that they had exploded and scattered. I drove a car to the Hyundai Car service center to claim it, but they ignored me. I claimed this on the Hyundai America site, but the answer is that they won't fix this under the warranty. This is a panoramic sunroof, and it should support our family in the car accident. But it is easily exploded without any impact from outside. It is a safety-critical issue, but Hyundai doesn't take care of this issue.

On two occasions, once at 70mph and once at 45mph vehicle suddenly lost power and displayed warning to check collision system, there were no vehicles close enough to warrant this. I had to limp the car to the side of the road as safely as possible and shut car off, wait a few minutes and restart vehicle to clear error and allow proper power/ acceleration again.

While driving to work today [XXX] on or around [XXX] on [XXX] from Riverview to downtown Tampa while doing about 68 MPH, my emergency brake deployed for about 6 seconds. The whole vehicle shook. There were no other vehicles around. Quite scary. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving the sunroof glass out of no where exploded.

I purchased a brand new vehicle from Hyundai within 9 months the horn stopped working. It was replaced 10/2024 and now less than 1 year the horn has stopped working once again. Hyundai has not issued an extended warranty to the Santa Fe model when this has been a known issue with all there vehicles for this year.

There was a recall on the 21-22 santa fe for a issue with the transmission oil pump failure. I have a 23 which is not part of the recall but this is exactly what happened to me and now the transmission has failed completely with 68,000 miles

At 22000 miles wheel speed sensor went out, all control system shut down and car became unstable. At 44000 miles fuel injector went out, was driving on freeway and car started shaking and losing power, then in parking lot would not start at all, had to be towed to dealer. This is way to many breakdowns for a car with such low mileage.

On May 15th, I was involved in a serious accident caused by a malfunction in a rental vehicle provided by Enterprise a 2023 Hyundai Santa Fe. After reversing into a parking spot, I placed the vehicle in “Park” and exited the car to retrieve belongings from the trunk. My young son remained in the back seat. To my shock, the vehicle suddenly began to move on its own despite being in “Park.” I immediately ran to the driver’s side and jumped back into the vehicle in an attempt to stop it. I pressed the brake pedal multiple times, but the car would not respond. I also pressed the “Park” button repeatedly, yet the vehicle continued to move uncontrollably. The steering wheel was unresponsive, and I was unable to redirect the vehicle or bring it to a stop. The car ultimately crashed into two other vehicles. During the collision, one of the vehicles pinned my left leg in its door, causing physical injury. I am now dealing with both physical and emotional trauma as a result. To be clear, this incident occurred on a flat surface. No airbag deployed upon impact, and there were no warning signs or alerts from the vehicle beforehand which is highly concerning, especially for a modern electric/hybrid vehicle. This car presents a major safety hazard and, in my opinion, should be recalled and removed from service immediately before it causes a fatality. I have contacted Enterprise multiple times to report this issue and urge them not to rent this vehicle to anyone else.

While driving the engine dropped to 10 mph and would not respond to the pedal inputs. It is available for inspection. Dropping to 10 mph in traffic on a roadway doing 70 mph or even 35 puts everyone on the roadway in danger. The problem was not reproduced but was comfirmed by the dealer who inspected and serviced it. There was no warning before it happened but the dash displayed many warnings and even sent out an email when the engine failed. This was the fifth of five times that it has happened so far.

Transmission caused vehicle to loose speed on grade posted speed 70mph I could not get over 35 Transmission stuck in 3 gear or would stay in 8th gear unable to gain speed almost got rear-ended vehicle has a 8 speed automatic transmission it will not shift properly loss of power account improper gear for speed

My wife was parking the car at carport, all of sudden unintended acceleration happened and hit through the wall. The damage on the car was $12478.57 and damaged the wall and storage on both sides of carport. My wife is scared to drive this car.

On [XXX], a 2023 Hyundai Santa Fe SEL (VIN: [XXX] ) spontaneously caught fire ~8 hours after parking, per fire report (Walla Walla Fire Dept.). The fire destroyed the hyundai santa fe sel engine compartment and totaled 5 vehicles with a total value of over $400,000 not including personal property to the parties involved. I was not the Hyundai’s renter/operator; the vehicle was rented by a third party from Enterprise. Despite no active recall for this VIN, the vehicle contained: Mando ABS module, Mando EPS module similar to known defective parts of the same year, and Hyundai Mobis tow hitch harness, all of which have known defect/recall history in similar make/Model equivalent vehicles. This case may involve VIN exclusion errors or latent product defects similar to recent defects INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car loses power. The battery and key ignition light keep coming on. A message displays auto engine off. Please shift to n or p and start engine manually. After communicating and showing video proof of the incident, the dealership replaced the alternator and battery. The issues started around 5000 miles. The infotainment system lags and the car lags. Sometimes I am left on the road because the case refuses to cut on or off.

My car won’t shift on the highway and all of a sudden I can’t drive more than 40mph. It also has not wanted to let me press on the gas and make it go as I’m driving bc Its jerking 4 or 5 times before it’ll register and go. Also, not too long ago, I was in a parking lot and went to leave and my car never notified me that there was a huge pillar next to me and I crashed into it, it was in my blind spot and couldn’t see it. My car has had many many other issues in which I can’t list, but I truly bought a lemon.

Engine died suddenly at various speeds and a beeping alarm was activated along with the Malfunction Indicator (Check Engine), Engine Oil Pressure, and Charging System warning lights on the instrument panel. The instrument panel also read, "Engine off! Shift to N, then start engine”. The car must then be coasted off the road to safety. When the car was brought to a stop, the Parking Brake and Brake Fluid warning light was illuminated alongside the other warning lights on the instrument panel. The instrument panel also showed that the car was in Neutral; none of the gear shift buttons were operable. Pressing the start/stop engine button restarted the car, removed all alarms and warning lights, and the car operated normally until the next occurrence. This scenario occurred five times: 4.05.25, 4.15.25 (twice), 4.22.25, and 5.28.25. The odometer readings were 12,250, 12421 and 12,425, 12,454, and 12,976, respectively. I have videos or photos of the instrument panel for all events but the first one, frightened as I was by that initial experience. The car was taken to Hyundai of North Charleston (HONC) for analysis 3 times: 4.16.25, 04.22.25, and 5.29.25. On 4.16.2025 the service advisor told me that they found 2 diagnostic codes, one of which related to the front radar, so it was replaced. I picked the car up on 4.22.25 and drove less than 3 miles when the problem recurred. I immediately returned to HONC. On this visit the front upper camera was replaced. My car was at HONC for 3 weeks waiting on the part and completing the installation. The problem reoccurred on 5.28.25 and the car was taken to HONC on 5.29.25 for inspection. On 5.30.25 the service advisor told me they didn't find any diagnostic codes and could not replicate the problem. The advisor said I could leave the car at HONC or they could "release" to me. I picked the car up on 5.31.25. Afraid to drive the car now, its use has been limited to necessary local trips on roads that have pullover access.

Driving on [XXX] in Victorville; sunroof shattered. Originally thought it was a tire blowout but there were no indications on the dash, no alerts, etc. Pulled over when safe to inspect vehicle and to make sure my kids were safe. Upon pulling over and exiting the vehicle, I started to make my way around the car to check the tires. All 4 tires were completely fine. Made a second round to double check everything, see if something went under the car, there was no sign of any damage. As I was getting into the car I noticed a huge hole in the sunroof, it was completely shattered. Safety of my family was at risk but fortunately it was a chilly morning and the sunroof was closed. Vehicle is available for request if needed but it currently located at the local Hyundai dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When accelerating from a stop, my car will not go over 20 mph. It just revs up like it’s not changing gears . I have to pull over and park it. It runs fine afterwards. This does not happen all the time. Usually it happens once a month. It’s been to the dealership 3 times. They drive it around the block and tell us that they can’t replicate the problem. Therefore, they don’t troubleshoot anything and return the car to me. I’m truly scared to drive it. I wrecked twice at a red light intersection.

On two separate occasions, I was a stop light in high traffic. I was unable to drive my vehicle when the light turn green because of  no power. A message display prompting me to "shift to P or N to start engine." Unfortunately, that didn't work. I had to sit there for a few mins, signaling other motorists to go around me. Eventually, I had to restart my vehicle. I panicked because I felt unsafe as I was blocking traffic. I took my vehicle to the dealer and was told that there were no code  after the diagnostic test but yet the technician told me the door on the driver side is not aligned and I need to take it to a mechanic. I never got any alert that my door is open so that diagnosis didn't make sense. I took my vehicle le to the mechanic to check the alignment of the door who in return told me that there was no issue with my alignment. I am scared to drive my vehicle because I don't want to cause an accident.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was towed to the dealer but was not diagnosed or repaired. The contact stated that the failure reoccurred, and the vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 55,917.

I had adaptive cruise control on and debris hit my windshield and I went into the rumble strip and eventually into the guard rail where the car essentially pingponged from there until it eventually stopped when the metal hit the front. It appears the emergency brake did not activate and the lane keep did not activate. My air bags did not deploy.

The car has shut down unexpectedly for at least six times while driving at roads and highways. When this happens, engine stalls and nothing works and all alarms and check lights turn on and activated. Driver has to pull the car to the roadside which cannot be imagined when in a highway with all cars driving at 65-70mpH and the car suddenly slows down to stop. The other problem is that when the car is turned off and on again, all alarm and faults go away, and it can be driven again! It clears all safety and alarm checks and lights and behaves like nothing has happened. Car was bought on June2023. The first incident happened on Aug2023 and the next one on Sep2023. The next incidents on Feb2024, Sep2024, Nov2024 and the most recent on March 2025. The car has taken to the Sport Durst Hyundai dealership (Durham, NC) after incidents, however dealership did not perform any repairs in first four times claiming they could not duplicate the incident! (service reports attached for 3) After the third incident, we opened a case with Hyundai company trying to invoke the Lemon law, but our request did not go through despite all evidence we provided. Shamefully, their final suggestion to us was to sell the car! This was around March/Apr 2024. (Final decision letter attached) On fifth time, the driver did not shut down the car and towed it to the dealership while leaving electrical system on. They checked the car and claimed they found the cause and changed a part from car claiming it has been fixed. This was on Nov.2024. At the time we did not notice but, apparently that was a lie to make us quiet. The last time (sixth time) the same incident happened on [XXX]. The car was towed to dealership and is left there. We do have all screenshots from engine failures, although the dealership tried to wipe the history at some point.

Front brake failure at 3k miles. Rotors warped so badly they failed to properly stop the vehicle. Vehicle shaking immensely Transmission failure at 11k miles. While vehicle is in Drive mode the transmission is stuck in first gear and will not shift. The tachometer was redlining at 6k I had to use the paddle shifters to get the transmission to shift. I was driving the vehicle as a manual transmission when I own an automatic.

Early March 2025 the vehicle was put car in park, got out of car to close yard gate, turned around to walk back to car but car was rolling forward and hit the flat bed trailer causing approximately $5000 in damage. It was put in park before getting out but jumped gear before getting back in. Another common problem is slamming the emergency brake on when attempting to drive. Was at a red lite left turn stop sign with foot on the brake. When the light turned green took foot off brake & put foot on accelerator to go forward, the car slammed the emergency brake on. This has happened approx 6 times in the 1-1/2 years of ownership.

Every time it rains, one of the dual tone horns will fail. I have had the horn replaced 2 times. I am beginning to have a problem with the horn again after this last rain. It is a matter of time before it fails completely after a rain and becomes unusable. I feel this is a significant warning feature that MUST be reliable.

The accelerator stuck and the vehicle crashed. The vehicle is totaled. It happened [XXX]. No one has yet inspected the vehicle. I notified Hyundai about 5 days ago. The phone number of the towing company is 516 433 1011. The following link is a YouTube video of the accident: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The sunroof glass violently shattered/exploded while driving the vehicle. The manufacturer claims the window meets current standards and is not defective. The curtain or fabric cover was extended covering the glass panel otherwise the driver would have been covered with broken glass.

The purchase price was $35,800. As of today, I have paid a total of $24,590. The vehicle has a manufacturing defect that has significantly impacted its performance. The engine has been problematic, as it appears to be consuming oil, and it often fails to start on the first attempt, requiring me to press the button multiple times. The most concerning issue is that the car can unexpectedly shut off while I am driving. Additionally, there is an abnormal noise coming from the engine. I consider this situation serious, as it poses a significant risk to my safety. These symptoms appear on January 13/2025. I want to emphasize that I have completed all scheduled maintenance on time. I filled out reports regarding this issue, and I have attached two reports that confirm the vehicle is consuming 2 quarts of oil per 1,000 miles, vehicle is consuming oil due manufacturing defect. These reports were given to me by Safford Hyundai.

Took vehicle to the dealership on Jan 3, 2025 for the 15k mile oil change. They informed me they completed the multi-point inspection, with no issues discovered. Jan 10, 2025 I attempted to us the horn and discovered it didn't work, so I immediately went back to the dealership and scheduled a service, to troubleshoot the horn. Jan 20, 2025 dealership discovered both horns were defective and replaced both. Very strange for both horns to die so early.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving 45 MPH, the message "Shifter System Malfunction - Service Immediately" was displayed. The contact stated that the vehicle failed to shift into the park or reverse. The contact activated the parking brake and turned off the vehicle. The vehicle was towed to the dealer but was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 18,192.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving at approximately 55 MPH, the horn was inoperative. No warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the horn needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 7,600.

In January, 2024, my vehicle (2023 Hyundai Santa Fe) started shuddering when brakes were applied at high speed, on quick or hard stops, in stop and go traffic, and especially going downhill. I had only been driving the vehicle for about 5 months. I took the vehicle to an independent mechanic, who explained that my front rotors had burn spots. He recommended that I have them resurfaced. I did not want to pay for the problem to be fixed when I believed it was a factory defect and should be covered by warranty. I asked the Mission Hills Hyundai dealership Service Department to investigate and correct the problem, because I felt that my family's safety was jeopardized by faulty brakes. They showed me the burn spots on the front rotors and recommended resurfacing. They said I could wait for the pads to wear down and do the resurfacing at the same time as the pad replacement. Their estimate for resurfacing was higher than the one from my mechanic. I found a Hyundai Technical Service Bulletin, Number 23-BR-004H, which described the exact defects of my vehicle. I returned to the dealership with the TSB in February, 2024. They replaced the two defective front rotors and front disc pads at no charge. The shuddering was no longer evident, and I thought the problem was resolved. However, 10 months later in December, 2024, I once again experienced the shuddering while braking on the freeway while going downhill and when slowing for stops from high speed. Since I had been told that the new rotors and pads were covered by warranty for 5 years or 60,000 miles, I returned to the dealership on 1/16/25 and asked them to evaluate the brakes again. They said that the front rotors again had burn spots. They once again recommended resurfacing at a cost of $249. I reminded them that there was a warranty on the new parts, they claimed that the only warranty was for the original parts that had been replaced. They agreed to resurface no charge. Please investigate and respond to my complaint.

Automobile approached and stopped at stop sign. When accelerator pressed to continue, car remained in place, shuddering (as if transmission were slipping),and making significant noise. Car would not shift out of gear, nor move. Operator shut off car and then restarted car. Car started normally and was in park without shuddering. Expectations at busy intersection was that it was my turn to move and did not do so, creating doubt on what my car might do next. Traffic flow was briefly confused and some drivers honked and were unsure what they should do. This could have caused an accident with an impatient driver re-ending my car, or with others going through the intersection "out of turn" and unclear on my situation. No lights or other warnings were displayed before this incident. It has not re-ocurred. I brought into the dealer who had no other reports of this type of behavior.

Just purchased the vehicle one week ago. I bought it used from a Hyundai dealer. Just discovered that the horns don't work, either the high tone or the low tone. I discovered it when I went to use the horn to alert a driver who was coming into my lane, pushed the horn on the steering wheel and nothing! I've checked the fuse and it is fine. Internet research shows this to be a prolific problem with Hyundai's. Because the horns don't work, neither does the alarm system. I tested by pushing the panic button on the key fob. The lights flash, like the alarm is trying to fully work, except the horns don't sound. I will be bringing it to the dealer as it is still under warranty.

First- it has been reported to dealer at least twice when car was in for other service. They said they could not reproduce. When speeding back up from a stop on near stop, especially in a right turn, the engine will not accelerate. After a second or two it finally takes off. During this time, I fear getting hit by another vehicle, either from behind or to the side. It is very scary and puts me and my passengers at great risk! There was no warning indication at all. The date mentioned was the most recent time, but the issue has been happening since the car was brand new. Again, NO help from the dealer.

Emergency brakes engage while driving for no apparent reason. This has happened on several occasions over the last 6 months.

Horn Failed. Would not sound, making it impossible to warn people if car might hit them or their vehicles or about any other issue they would need timely reporting about. Car was brought into dealer and 2 horns assemblies were replaced as non-functional

While driving the engine dropped to 10 mph and would not respond to the pedal inputs. It is available for inspection. Dropping to 10 mph in traffic on a roadway doing 70 mph or even 35 puts everyone on the roadway in danger. The problem was not reproduced but was comfirmed by the dealer who inspected and serviced it. There was no warning before it happened but the dash displayed many warnings and even sent out an email when the engine failed. This was the fourth of five times that it has happened so far.

Vehicles' charging side deck will heat up any phone we put in to charge inside that slot. We brought this to the dealers attention a couple times but they stated I needed to pay a service fee to have it looked at. It began happening a few weeks after we purchased the vehicle. We have not used the port ever since.

SAFETY ISSUE: EXPLODING SUNROOF While driving my 2023 Hyundai Santa Fe Limited to work approximately at 6:15AM CST on 9/30/2024 on I-170 southbound in St. Louis, MO, the panoramic sunroof exploded. Car systems did not contain an indicator light or alert that the sunroof was stressed and about to explode. No debris (stone, rock, tree branch, item falling off a car or truck) or falling bird causing this sunroof damage. After the sunroof explosion, I continued driving. No other damage to my automobile or any other car on highway.

Shuddering Issue with Current Vehicle: - Problem: Progressive shuddering during take-off, accelerating, slowing down, and braking uphill.

The vehicle's software update initiates upon start-up without the option to delay to a different time. The three updates I've received this year have taken 20-30 minutes each to complete, while I'm traveling. These updates disable hands-free calling, all media and GPS. I can't confirm if any other vehicle safety components are disabled. I don't use them. I contacted my dealer and they stated that's how it works, and there is no option to delay the update. When the update initiates it states the update can continue without the vehicle "ON". Wouldn't it be safer to have the ability to schedule it to a later time when the vehicle isn't being used? Similar to a cellphone update?

Vehicle sun/moon roof exploded/shattered while driving on the highway with no apparent external cause. Sunroof was closed, driving middle lane, slightly below speed limit. Fortunately the material blind was closed otherwise the glass could have struck the occupants. Drove to manufacturer dealership who insisted it was a stone and not a manufacturer defect and to claim through insurance, which means a $1000 excess. I know this happens on various vehicles, noted on many forums.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while his wife was driving at approximately 65 MPH and depressing the brake pedal to slow for a vehicle that had passed and switched into the lane she was driving, the vehicle was shuddering. The contact stated that as soon as she had stopped depressing the brake pedal the shuddering ceased. The contact stated there was no warning light illuminated. The contact stated that the shuddering when the brake pedal was depressed was intermittent but was recurring at various speeds while slowing down. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the brake pads and rotors needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was 18,756.

The seat belt in the middle seat of the second row did not work. And it was not fastened. So when braking, my child was thrown toward the center console. I think it's a big safety issue if the seat belt doesn't work.

Brake rotors warped. Beginning at approximately 5k miles, the steering began exhibiting a juddering upon applying braking. Over time, the juddering became more pronounced. At approximately 15k miles, I took the vehicle to the dealer. The dealer confirmed that the brake rotors were warped. The defective brake components put my safety at risk, as well as the safety of my passengers and others traveling on the road by impairing my ability to safely stop the vehicle and impairing my ability to safely operate the vehicle while braking. There were no safety lights or warnings. I am aware that there has been a technical service bulletin for this exact issue for this model/year vehicle. Neither Hyundai nor the dealer ever altered me to the possibility that the brake rotors might warp due to defective components. Hyundai has thus far refused to cover the full cost of repairs, totaling over $1,400.00.

I was driving the car moving in reverse to exit my driveway. I placed the car in Park and while the engine was running I exited the car. Upon exiting the car, the car immediately started to roll forward and crashed through my garage door leveling it to the ground. The car continued moving forward into the garage and came to a stop blocked by built in shelving at the back end of the garage. I could have been injured had the car started to roll while I was exiting the car or had some been in front of the car. No warning lamps or messages prior to the incident. The car has a safety feature if moving in Drive or Reverse and the driver door is opened the car shifts into Park. That feature failed. The car was inspected by a Hyundai dealer and claim no error codes found and dismissed any other information as provided in this report

Driving at a low speed and blind spot warning light comes on, then all warnings light up and car loses all power and goes into limp mode. Engine light stays on, but will start back up after it is shut off, open and shut car door and restart. Engine light stays on. Has happened to me three or four times. In the past, the engine light will eventually go off before I can get it to the dealership. Hyundai said they couldn’t duplicate the problem last time it was taken in, so nothing could be done. Gives error code P063512 each time and says EMS which I assume means emissions.

Currently have 518 Diagnostic History Codes (DTC)in memory. Additionally, I have 3 Active DTC’s. The codes are: DTC C160C87 DTC System CHASSIS DTC Sub System LKAS, and DTC C160C87 DTC System CHASSIS DTC Sub System SCC, and DTC C163881 DTC system CHASSIS DTC Sub System SCC FIRST OCCURRENCE: during actual assembly in Montgomery, AL plant. I have asked three Hyundai Service dealers for help. All have tried. Noting noted that contributes to the issues above. At first, my dealer replaced the front camera. Was told it was a heating issue. I have contacted Hyundai BLUELINK service for help. An information report was filed, TWICE. The first report I received feedback that Hyundai’s engineers had corrected the issue. On the following day, the codes returned. A second concern was filed with Hyundai BLUELINK. Hyundai Motor America Case#: [XXX] to wit: “Thank you for contacting Hyundai Motor America. We are in receipt of your e-mail and one of our representatives will get back to you shortly. Sincerely, Hyundai Motor America” Is my vehicle going to fail and cause me injury while operating it on an Interstate highway? This is quite concerning as I drive my car. All I want from Hyundai is to get this issue repaired. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased my 2023 Santa Fe brand new off the show room floor in Jan 2024. After about 6k miles when braking on the highway the entire vehicle would shudder and shake including the steering wheel. I took it into the dealership where I was informed this is a KNOWN ISSUE with this year/make/model with the rotors. They claimed they would turn the rotors but if the issue persists they would replace them. About 2k miles later (apx 2 months) the shuddering happened AGAIN. So I made an apt to get them replaced where the new service tech tried to tell me again this is a KNOWN ISSUE but now I would be responsible for a $250 replacement of the rotors. I refused to pay as they are within the 12k or 1 year warranty and they refused to replace them. That service tech also said the day prior he had to deliver that news to 4 OTHER patrons about the replacement of their rotors. I feel extremely unsafe in this vehicle and the issue is still not fixed as I have a claim in process with the manufacture directly. The claim was put in on 12/7/24 where I was told I would be contacted within 2-3 BUSINESS DAYS by a manager due to my claim being escalated. It is now 12/15/24 and still NO CONTACT from Hyundai. The vehicle shuddering is increasingly worse and worse and I feel very unsafe in this suv.

While travelling at highway speed, attempted to accelerate to pass slow traffic. Rather than accelerating, the car hunted for a gear, and wouldn't shift properly. The car downshifted but engine would not go beyond 4000 RPM and speed remained the same. This has happened multiple times. By unexpectedly not accelerating, this created a risky situation by not allowing car to pass slower traffic as expected creating a potentially dangerous situation. (Video of one of the instances exists). No warning lamps, messages or symptoms occurred up to that point. Car was brought to dealer but since no codes were contained in the computer, they said there was no trouble found.
