Total loss of power while driving occurred on 2 separate occasions driving the Hyundai Sonata. The dashboard lit up with multiple failures with no warning, and car lost all power. Both times were in peak traffic conditions and on one of the two instances, a very dangerous mountain road with very little time to react. Towed on 2 occasions to 2 different dealers with no clear cut fix for the car. These were very scary and dangerous incidents and I am afraid to drive this car to be honest. Hyundai has not done much to contact or reassure me that they were dealing with the situation.

Driving this passed saturday and my car was jumping when i would slow it down to decrease my speed. Once my car got to 5mph it-??ll jump forward then it would stop. When i went to accelerate it would pick up no speed until 40mph then the engine light came on. I went to get a diagnostic from autozone and it was my power train system having an issue. I have no clue what that was. Went to make an appointment for hyundai NO appointments for a month! What happens if the car shuts down on me" or doesn-??t brake when i press on it"

Driving on highway went to pass a vehicle and merge into the next lane, when car lost speed. Pulled over and tried to restart car, car restarted only to shut right back off. Put quart of oil in and shortly after there was a clicking noise when I got up to speed, I had to put two more quarts in as well as a cleaning additive. Cannot drive over 8 mph without car making noise

The check engine light came on and wouldn't accelerate normally. The speed was delayed and cutting back and wouldn't pass 40 mph. Upon taking it to a local shop it had to be taken to the buying location by road side assistance. After the service department checked into the problem it now needs a new engine. They stated there were metal shavings in the motor. This was transferred by a known problem in the 2.4 L motor that hyundai has put in their vehicles with problematic bearings. This happened within 2 months of buying this vehicle. We Can't drive it at all now so it's still at the shop.

- Philadelphia, PA, USA

It's knock sensor issue code was showing since 85000 mileage, dealer just got rid of the code and said can drive safely. Then again at 101000 mileage knock sensor code and Hyundai dealer said software is updated can drive safely. Also it's engine oil burning faster that we keep on topup oil all time. Then at after 108000 mileage my car started overheating, & it's engine seized. Now Hyundai don't want to fix such problems. I don't know maybe it get fixed, then catches fire on highway can cause death.

Recall on my 2017 Hyundai Sonata was repaired 9/13/2019, purchased the vehicle with financing on 7/16/2021. On 8/18/2021, had vehicle towed back to the dealership and explained the issue. Engine knocking, tire pressure and engine lights on, frequent stalling, turning off, smell of gas and something burning, loss of power to the engine, car could not accelerate to 60 MPH. The dealership had my car till 9/20/2021, power train warranty was denied and voided, no loaner car was given, was not offered any reimbursement for car rental by dealership and Hyundai corporate. Although car is included in Theta class action lawsuit. I was correct about issue with engine, but the dealership replaced engine with used parts. No later than five days after having my car back, the engine and tire pressure lights came back on, car is tugging, and the engine noise is louder. I don-??t believe that they replaced the engine with OEM parts.

After transmission was replace in December 2020, noticed starting in Jan 2021, that vehicle did not stay in park and rolled back up to 5 feet from where parked. Pictures from parking lot, 3/6/2021 rolled back 5 feet from where it parked. Mileage on 3/6/21 was 96858. On 4/15/21 we have video with the noise that it is making when in park and rolls back (unable to attach here). Mileage on 4/15/2021 was 97881. Car was parked in a handicap spot at a restaurant. The amount of rollback could cause someone walking behind the vehicle to be crushed or killed. The consumer stated the failure occurred on numerous occasions, not only on an incline. The dealer was unable to replicate the failure; therfore, the dealer was unable to repair the vehicle.

My car won't turn on when I turn the ignition key. It stays silent no click or anything indicating its trying to turn on. The vehicle is always stationary when this happens. It randomly does this and rarely it turns on when I turn the ignition.

- Bell, CA, USA

Car gives warning message to "immediately shut off the car to prevent damage ".... this has happened numerous times and Hyundai doesn't seem to have a fix, and doesn't think its a safety issue. This is a safety issue particularly when you are in heavy traffic with no place to move over to shut off the car.

When starting car, it starts shaking real hard then cuts off. It doesn't at times.

On 7/17/19 my car lost power while driving on city street. Unable to steer or control vehicle. Took to dealer who said there were no error codes shown and that it was the electric oil pump. On 8/12/19, the same thing happened while driving on expressway. Complete power failure while vehicle was in motion. Unable to steer or control car. Took back to dealer. Again, no error codes found. They later claimed that a relay had melted and that was the problem. On 12/28/19, again driving 70mph on busy expressway, vehicle lost all power and I was unable to steer car. Took to dealer on 12/29 after it happened a second time in two days. There were unable to look at vehicle that day and told me to bring back next day. It stalled again while I was leaving parking lot, I asked the maintenance tech to come and look to see what was happening, he refused. Dropped car off on 12/30. On 1/2/20, dealer called to say no error codes found, after driving 100 plus miles, were unable to determine cause of problem and I should pick up my vehicle. I explained this is unacceptable. They called me back later claiming it is the electric steering column portion of motor control power steering rack and want $1800 to fix. This is a major safety issue, loosing complete power and ability to steer while driving. Dealer has done nothing to reassure me that this is the actual problem.

I bought the car used from a scam dealership. I had no idea that there was an engine recall in January until it turned off and on just one week after leaving the lot. I brought it back to them, obviously, they said it wasn't their problem. I then took it to college park Hyundai to have them update the knock sensor and diagnose the issue. After an extended road test, it was decided that my problem was an isolated incident. Yet I took it to other dealerships, and pretty much everyone says the same. My dash cam has recorded the moments when the car stutters and fails to accelerate before turning back on a couple seconds later. It has happened on curves and I have nearly drove off the highway due to this. It only happens when the car is reaching about 60mph. I live in md but work in va. I'm paying high interest for a crappy lemon car. I even contacted corporate Hyundai, and they just laughed and called me stupid for buying a used car...

The contact owns a 2017 Hyundai Sonata. The contact took the vehicle to sport durst Hyundai (4507 durham-chapel hill blvd, durham, nc 27707, 919-251-5996) to be repaired per manufacturer recall service campaign number: 953. After the recall repair was performed, while driving 35 mph, the vehicle began to stall and the check engine indicator flashed. The contact spoke with the same dealer and was informed to bring the vehicle back to the dealer the next day. The recall repair was performed again, but the same failures recurred while driving 40 mph. The manufacturer was not notified of the failure. The vehicle had not been repaired. The failure mileage was unknown.

Car loses power in situations where you need to accelerate like passing and merging. We just bought this vehicle 8/3/2019. This is bery dangerous. After the car jerks and loses power, then it suddenly comes back full throttle. I was almost hit by another car as iost power while merging into 55mph traffic. The car is now in the shop and we are awaiting a diagnostic. This is very dangerous and if not corrected should cause these cars to be taken out off the road.

If the vehicle is left in drive and turned off it will roll backwards. I got out of the driver seal and the wife was in the passenger seat and turned the vehicle before she got because she was on the phone. The vehicle rolled in the road way, thankfully nothing happened to anybody. According to the dealership the newer models do not do this.

- Swansboro, NC, USA

My vehicle is under 70,000 miles. I was informed by the dealer service department it needs a new transmission. The transmission is not shifting properly and has caused the vehicle to stall on the road on a couple of occasions. The vehicle is making a grinding/clicking noise when it shifts. The dealer is not honoring the power train warranty from the manufacturer.
