My daughter had her car towed to the Hyundai dealership because of engine failure. Upon inspection we learned that there was a recall on the engine. We had to wait a few weeks so that the dealership could get approval and authorization to replace the engine. Finally after 3 or so weeks we got a courtesy car to drive. After about 4 weeks our car was finally ready to pick up so we took the courtesy car back and picked up our car. After about 4 months or so maybe my daughter went to her friends house one afternoon and her and her friend left in the friends car. They had been gone maybe 10 minutes or so and her friends neighbor called her friend and said that her car was on fire and they had already called the fire department but the car was engulfed in flames and before the fire department could get to it the whole car burnt to the ground. Nothing left but the shell of the car. The fire marshal said that the source of the fire was under the hood. Thats where the fire ignited he said. Luckily no one was injured or hurt. But this is after I had the recall motor put in. It was super scary and very upsetting because no one seems like they want to help us either.

Sitting in parking lot with car running in park and passenger airbag deployed with person sitting in the passenger seat. No injury to passenger but windshield broke and driver seatbelt will not move now.

Brake light appeared intermittently while I'm in the middle of traffic.my vehicle's hybrid system warning light came on aside from the brake light and tells me to pull over and not to drive the vehicle.i towed my car to the dealership for inspection.after inspection done ,the service advisor tells me that they need to change the abs module due to possible internal leaking besides the fuse.they quoted me $3574.71 to fix the abs module excluding other brake components.i asked them to change the fuse only.Abs problem and brake light are still on and vehicle is not drivable.

Approx one year post engine replacement, and 2 weeks prior turbo system replacement, I am having major issues with my sonatait struggles to stay started, it always hesitates and doesn't want to move when I press accelerator, shakes jolts and shudders, the smell of burning oil comes thru the vents and even smoke comes out from under the vehicle. The engine is leaking masses amounts of oil that seem to be leaking from all over the under carriage and half way to the back underneath the car, oil is in the wheel wells, and even splashed on the rims, the spark plugs are covered in oil, huge plums of white and dark smoke come out of the tailpipes, literally blinding anyone behind me, press the accelerator to the floor and it just shudders and smokes even more, check engine light is on and states malfunctioning turbo system, boost pressure sensor malfunction, sluggish will not gain speed, oil within the turbo blow by hose and in intake hose area, now I have coolant pouring out and the reservoir the coolant will be literally boiling. This is not good at all especially after a year post engine replacement and turbo replacement. When the car is started I push start and car struggles to start the starter keeps screeching and car shudders for a good 45 seconds before it either dies out or finally starts. This vehicle should be a lemon and bought back regardless of age condition etc. A vehicle after engine replacement of only one year should not be pouring oil out of the engine, failed head gaskets,misfiring and leaking coolant. I keep receiving recall notice after recall notice in the mail stating I have recalls that need to be addressed but when checking using my vin it says there are no recalls needing fixing, that makes me uneasy and I don't feel safe driving the vehicle I lost faith in it all together

Hyundai states this vehicle may catch fire while parked or while driving. They have advised not parking inside due to fire risk. We do not feel safe driving the vehicle any more than on local low speed city streets, as it might be impossible to safely pull over should it catch fire while driving at high speeds on a highway. We have been waiting months for Hyundai to fix this, cannot get a straight answer as to when that will happen. They have refused to provide a loaner or rental car, so we are currently stuck with a car that is close to completely useless and apparently presents a fire hazard even while sitting in our driveway. Can NHTSA assist?

Several times a week I get "Hybrid System Warning. Check Brakes" that comes with red flashing light on the dash and beeping noise. When I turn the car off, give it a few seconds and restart the car, it goes away. It has mostly been happening when I am parked so it is not an issue to shut it off and restart. Two days ago, this happened while I have driving on the street and when I applied the brakes, it went down to the floor with grinding noise. I was going about 35 MPH and no cars in front of me so I was able to come to a stop on the street with hazards on. I turned off the car, restarted it and the issue went away. I have researched this online and it looks like many people are having the same issue. Many have taken their vehicle to the dealer to get the issue fixed and the dealer is unable to fix the issue because they cannot recreate the problem. I am afraid that this might lead into an accident and feel like something that Hyundai should do a recall on.

I started financing my 2012 Hyundai in 2019. Feb of 2021 the vehicle stopped without any warning. I paid to get the vehicle towed to Brandon Hyundai in which the did replace the engine and the starter free of charge. I was able to continue to drive my vehicle everything seemingly fine. Fast forward to late 2023 the engine light is back on, I’ve taken my vehicle to Hyundai dealership several times relating to the engine light being on each time having nothing resolved in regards to this matter with Hyundai stating theres no one there who’re able to inspect the engine. My oil light has remained on for a number of months in 2023 I’ve had to get an oil change several times this year and Hyundai isn’t able to explain as to why the vehicle isn’t retaining oil.12/15/23 around 11 pm the vehicle began to make an unfamiliar noise, stall, jerk and not accelerate. I am now unable to drive my vehicle and have to loss hope in my vehicles reliability and most importantly my safety.

Alarm started and Hybrid brake check warning instructed to pull over and do not drive. This happened while driving down the road. The car lost power and would not accelerate. The brakes were gone and were making a grinding noise.

The ABS (Antilock Brake System) or BMS ( Brake Module System) warning light illumination came on flashing “DO NOT DRIVE “ and the brakes sieze-up making it impossible to drive. Key Hyundai in Jacksonville previously charged me $2600 to replace the BMS and within warranty. A few months later the same company charged me another $342.56 to diagnose the same issue. I had to rent a car for $700 while in the service repair department. Key Hyundai was unable to fix my 2012 Sonata hybrid except offering me a replacement hybrid battery and control system for $12,900. I declined. I believe that the campaign 251 involves this problem. I had to get the car towed to another mechanic that is currently working on the vehicle.

I noticed a clicking noise when pressing and releasing the brake pedal that had not been there before. I started hearing that sound 3-5 days ago.

Daughter sold car as junk for $200 to service guy at shop not knowing engine could be replaced. Dealers are not being forthcoming about replacing the engine. In this particular Hyundai Sonata, which, even though was replaced, previously, was known and expected to fail again according to service people. Hyundai needs to be held accountable for this issue and not just brush off the problem and not make it public that all these cars should be recalled. Daughter could’ve been hurt on the interstate and we’re fortunate. She was not hurt but she was very frightened by the ordeal, forced to purchase a new car as she was told her car could not be repaired by repair shop, at great expense, and great stress and frightening experience for young girl.

Driving and vehicle caught on fire under hood of car

I went to start my car up 10 days ago and it began to alarm with a message to check the brake system. My car was stuck and wouldn't drive. This also happened in July 2022 while I was on the highway. I could no longer accelerate and the gas pedal no longer gave power. I had to put on my hazard lights and coast to the far right lane. I took it to the Hyundai dealership near by and they said it wasn't safe to drive. I left it there and was told that Hyundai would replace the part in good faith at no charge but charged me $700 for labor. This is becoming a problem.

I went to get my car fixed at a local garage but the employee came back with a recall information form printed out and said my engine and oil consumption problem was under a recall and would not charge me for the work. Hyundai dealership in Brockton. Ma refused to fix the issues & made my car further damaged and gave me a 1 week rental. I’ve had this car for a little over 1 year.

The car completely shut off in the middle of the road. It coasted to a nearby gas station and would not crank back up. There was NO oil in the vehicle, but no leaks and is up to date on oil changes and servicing. After putting oil in the engine, the car was able to crank and we attempted to drive it home. It stalled in the middle of the road and completely shut off and would not drive. It had to pushed out of the middle of the road, stopping traffic and risking our safety. Two mechanics saw us and stopped by to take a look. Upon inspection of the oil/engine they noted metal shavings (gritty) oil and the engine sounded like a propellor when we tried cranking it. It is available for inspection, however it is currently sitting on the side of the road in someone's yard. This problem has been noted on a recall with Hyundai Sonata vehicles, (metal shavings inside the block, debris circulates through the block and ends up stuck in the oil galleries, which is exactly what appears to have happened) It has not been inspected yet, I'm trying to see where I can get it towed. There were no warning lamps whatsoever before it shut off. Now, the engine light is on. and the oil light came on after it shut down the first time, but went off upon putting oil in it.

Due to the recall of my car's engine (VIN [XXX] ), on July 11, 2023, I dropped off my 2012 Hyundai Sonata to get my faulty and failing engine inspected at my local Hyundai dealership. After being approved for an engine replacement, I submitted the necessary paperwork proving ownership and routine maintenance of my vehicle. Two months of ineffective and infrequent communication went by thus leaving me without my vehicle. Unfortunately, Hyundai Motor America/corporate headquarters made it increasingly difficult to meet all their prerequisites to have my recalled engine replaced, which, ironically, is due to their faulty engineering. To replace the engine myself would cost nearly $5000. After finally being given confirmation that all necessary documents were submitted, Hyundai Motor America (HMA) denied my engine replacement stating completely false and confusing reasons. The reasons (attached) genuinely proved the company's disinterest in helping me; I have never requested an engine replacement before nor have ever owned a Hyundai before this one--which will be my last. When questioned, an HMA representative referred me to the Better Business Bureau, confidently believing the BBB would overturn HMA's decision. Unfortunately, the BBB was unable to assist due to the age of the car. Any class action suits against Hyundai only cover vehicles manufactured between 2013 and present-day. That said, my car is still unsafe and inoperable, which, with a pregnant wife (who is also in the National Guard), is absolutely unacceptable. I feel compelled to escalate this situation until it is resolved. With the above stated, I would like Hyundai Motor America to replace the current engine within my 2012 Hyundai Sonata and also provide proof of my previous “requests” for an engine replacement---which do not exist.

Cracked Dash Board The Dash Board has two cracks that run from Windshield to Passenger area. Located right where the SRS label is and the airbag is located and second crack is about 5 to 6" to the left. Dealer states that the Airbag will not deploy correctly if needed. I have read a lot on line about this issue, . In cases that Hyundai would correct the issue but in my case they will not. I have spoken with someone that had same issue and the Dashboard was replaced by Hyundai because of my very concerns. I am looking to see how this can get replaced without me having to pay $4000 to get it repaired. This car has been maintained and kept in very good condition.

I found a re call (google) for stuck brake lights. 2011 - 2012 Sonatas. I purchased the car used, and was informed that everything is working and in order.
