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...

Over the past month my car has been in the shop four times due to it malfunctioning while I am driving it - and that is not including when I took it in at the end of August because the trunk merchanism broke and it wouldn't close. The first time happened over labor day weekend when I was on a roadtrip, out of nowhere the car would not accelerate and, like others on the nhsa website have stated, it was very jumpy and wouldn't go past 45 mph. I took it to the dealer where they replaced a safety recall in the wiring system and it worked fine for a few days before it had the same problem again. When I took it to the dealer the second time they told me the engine needed to be replaced because the engine was essentially broken and there were little metal pieces inside. It took a week to replace and then everything was fine for a few days until yesterday. Yesterday the battery light turned on and the repair shop let me know the battery was in good health but low on charge so they charged it and it seemed to be working fine. Then this morning while on the highway all of the emergency service lights (check engine, check brakes, etc.) came on at the same time and the steering wheel locked up and it was undrivable. I by some miracle managed to pull the car over where I had to get the car towed to the dealer where I am awaiting to hear what is wrong. Do not purchase this car. After reading up on it apparently there seems to be issues with the engine and electrical system, that is extremely dangerous. I was lucky enough to not hit anyone but I could have been seriously injured all four times the car malfunctioned. All of these issues have been confirmed by the dealer to have been due to manufactural defects - something that is out of my control and shouldn't happen for a car that is under 26K miles.

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.

2017 Sonata sport uses 1/2 qt of oil every 1000 miles

- Bartlett, TN, USA

After driving an hour or two, when you stop and fill her up with gas, the car engine will not start after it's full and you're ready to get out on the road again. You have to wait like 20 minutes and maybe more, before the car starts again. Meantime, the gas attendant is already annoyed why you can't move your car?

I purchased my 2017 Hyundai Sonata on July 21, 2017 in houston, tx. Early June 2019 I received a letter regarding a recall on the engine, I took it to the local dealership and got the required update. On June 17, 2019 my vehicle became inoperable on the highway due to the recall, which placed it in a safety mode and caused the engine light to blink continuously. I parked my vehicle, contacted Hyundai towing and had it delivered to a dealership. After four days with no call to update me on my vehicle, offer a loaner car or rental, I contacted the 800 number and was told there was nothing Hyundai could do to assist with the inconvenience they have caused. My complaint was sent to case manager, diane C. (714-965-3595). I never received a response from diane. On July 13, 2019, I traveled to Chicago, il, while on the highway going around 70 mph, the car again placed itself in safety mode, pulling it back down to 45 mph and causing the vehicles behind me to brake and swerve in the attempt to not rear end me. I immediately went to the closest Hyundai dealership, rogers Hyundai, 2700 S Michigan ave, Chicago il, 60616. The service manager, tony serpico, was no help to me whatsoever. He was very rude and insincere to my problem. I contacted the towing company again and had my vehicle towed to another dealership. I needed to return home for work so I rented a vehicle at my own expense. Diane finally contacted me after I called and sent 'alerts' to her several times. I explained the whole situation to her and have yet to get a response regarding my vehicle, a rental or my reimbursement. I am very upset at the way Hyundai has treated me throughout this whole ordeal, which is at no fault of my own. Instead of replacing the engine or buying back the vehicle Hyundai continues to put me and my family in danger.

After receiving recall mail, yesterday I left my vehicle at service. They gave me back my car and told me they have fixed it. After driving less than a mile the engine stoped and a yellow light turned on. Again left my vehicle at the same service, today I called them and told me that they will probably fixing it after receiving the part next week. If it won't get fixed they are planning to change the engine. Is this a normal process! and what happens to the value of the car if the engine changes?

Wirring handss, engine red lights on and can't go over 55 miles, start to shake

- Reston, VA, USA

For some period of time, now, I have lost engine power, while in motion. It happens sporadically when I cannot press the gas pedal for continuous motion forward. This has been happening on a highway as well as city streets. It pauses when I press the gas pedal and the delay is momentary. Lately when starting the car for the first time in the morning I hear continuous knocking until I drive for several miles, then it dissipates.

Campaign 953 I received a recall notice by mail for the knock sensor detection system software update and it was completed on 03/19/2019. The vehicle doesn't accelerate past 20 mph, jerks and hesitate. I contact the Hyundai dealer service department and told them about the problem and gave me an appointment for the next day. The vehicle was inspected and I was advised that the vehicle is not safe to drive, will not provide me a loaned vehicle and will not cover a rental. My wife just gave birth to our son on 03/21/2019 and we were depending on this vehicle to Transport the baby from the hospital to our home. I was basically forced to purchase another vehicle with another company, because the Hyundai representative could not give me a date or an approximation of when the vehicle will be fixed. I still owed $3500 and still paying insurance for it. I need help.

I was driving very slowly to make a turn into my garage when the car accelerated on its own and hit the side of my house breaking through a patio guard rail. The front wheels of the car went over the bulkhead. Insurance company sent a wrecker to retrieve the vehicle. The insurance company totaled the car. This unintended acceleration had occurred once when I was driving on a state road in cruise control when the car accelerated beyond the set cruise control speed. This occurred again on the day before the accident. This unintended acceleration had also occurred when my husband was driving the car while in speed control.

My car is a death trap, I have already been in one accident and too scared to drive it, it just sits in my driveway. When you make a left turn at say a red light the car go's about 5 feet and then stops for 3 seconds, people behind honk at you and then the car rockets forward, I have already been hit once and the other driver took off, so I was left with the bill. The dealership says they can't fix it, even though it has a powertrain warranty. Please tell me what I can do.

Engine uses full synthetic oil at a rapid rate. One quart of full synthetic had to be added after driving only 3600 miles from previous oil change, and again at 4700, and even then the dipstick was still 1/2 quart below full when oil was changed at 4800 miles from previous oil change. Hyundai service technician could find no oil leaks.

This is my first time buying a brand new car in my mid 40's. I purchased the car (plug in hybrid) with only 25 miles on March 15, 2018 and after 7 days and 353 miles later, upon driving and coming to a stop in the city of philadelphia, pa, the car stalled and lost power. Warning message "check hybrid system." I had to step on the gas pedal all the way down to the floor and waited a second or two in order for it to move at a turtle's pace. Fortunately, I was able to find a safe spot to park the car. It was towed to a local Hyundai dealership near me and as of yesterday, 3/27, no diagnostic findings. I have notified Hyundai motor America and they have opened a case#. I have also reached out to the selling dealer to help me with this matter. This is extremely upsetting and disappointing, especially for me as new car buyer!!!
