general problems of the 2017 Hyundai Sonata - part 2

Abrupt and total loss of acceleration at full throttle at or near high rpm shift points. This behavior can be reliably reproduced by "flooring it" (all the way, including kickdown) and not letting go - as if one is executing a passing maneuver. The power loss will occur at the next shift point after kick down, and will not be cleared until the accelerator pedal is released and re-applied - or after approximately 15 to 20 seconds after the occurrence if the driver does not release the pedal. In cases where the pedal is not released after the power loss, the vehicle will surge suddenly after the condition has cleared and repeat the behavior described above. This behavior can be reproduced in any drive program mode (eco, normal, sport, ) and in both automatic and manual shift selection modes. Has been occurring since purchase. Parks Hyundai of gainesville, FL. States unable to reproduce, but a parks' employee confirmed occurrance.

I was driving the vehicle and it of no where the hybrid warming triangle comes up and I had to pull over. The car went in creep mode and then rpm and sped was capped.

Check engine light on,, throttle stuck/revving high in idle. Vehicle lunges forward without touching the gas pedal. Difficult to keep brake applied to stop it from lunging forward. Yet, little to no power over 25mph. Vehicle still under manufacturer, dealer and wrap warranty which was purchased at the dealership at point of sale. Vehicle affected by theta ii engine safety campaign. Hyundai extended the powertrain warranties for all affected vehicles. Manufacturer and dealer notified of the safety issue on vehicle. Both unconcerned and uncooperative. Upon attempting to get my vehicle serviced; was first told 8 weeks before my car can even be looked at. That no loaners are available(I am entitled to a loaner of a vehicle in the same class as mine per my warranty)I reiterated the safety concern. Hyundai and dealership failed & continue to fail to make this issue a priority. Explained that I could not drive the car for 8weeks. That it's dangerous, its going to kill myself or someone else. At the very least it will cause injury. Still no solution offered by manufacturer or dealership. Hyundai representative gave me an itinerary #(?) for reference. Also, attempted to sell me another warranty. I explained that my vehicle was covered by three warranties. I don't need another warranty. I need my car fixed and for someone to make this safety issue a priority! my car was a cpo purchased 5/28/20. Less than 30days after sale the check engine light came on & the car started misfiring. It was able to be serviced quickly, a loaner was given to me promptly and the issue was "fixed". This has now reoccured 6 times. Each of those 6 times my car was able to be brought in and serviced quickly, a loaner given to me. The dealership nor the manufacturer will resolve the current safety issue. The car is going to cause bodily harm and/or a fatality & they will have blood on their hands.

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.

The 2017 Hyundai Sonata didnt even go up to 60 miles ,the oil keep going out the vehicle but not leaking on the ground,the passenger seat in the front the nails,screws has came out on it's on, there was a recall on the engine ,engine light pop on flashing,oil light keep flashing on and off while driving the vechile scare for my safety.

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.

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.

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.

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.

Tl-the contact owns a 2017 Hyundai Sonata. The contact took the vehicle to a dealer(sport durst Hyundai 4507 durham-chapel hill blvd, durham, nc 27707 919-251-5996) to have a manufacturer recall(service campaign#953) performed on the vehicle. The contact stated that after the recall was performed, while driving at 35 mph, the vehicle began to stall and the check engine light began to flash. The contact spoke with the same dealer and they informed her to bring the vehicle back to the dealer the next day. The contact stated that after the second recall was performed, the same failure occurred again while drive at 40 mph; the vehicle began to stall again, the check engine warning also illuminated. The manufacturer had not been notified of the failure. The vehicle had not been repaired. The failure mileage was unknown. Jo.

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. . .

I received a recall notice in the mail on 06/27/19 stating that I needed to bring my car in to have the computer updated to protect the engine from excessive connecting rod bearing damage. I went in to have the service done on 7/1/19. When I came to pick it up the representative told me that the update may or may not have resolved the issue and that my car at any time in the future could go into what they called safe mode. He explained what that was and I truly did not want to take the car home. I no longer felt safe driving it. I contacted customer care by phone, corporate by email and have been told the same thing over and over again. They can only do something if the car malfunctions. I had scheduled a trip to montgomery the day after I had taken my car in to take my 80+ year old parents to see my sisters new home. I ended up having to rent a car because I did not want to take the chance on ending up stranded on the side of the road with my parents. There is apparently a harness that they can put on if the car malfunctions and I do not understand why they do not just do that if there is a possible problem that could occur. I no longer feel safe in my vehicle and feel that I will have to rent a car every time I have to travel. I feel totally helpless in this situation.

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.

Engine oil light or any warning lights and symbols never came on after engine had burned out all the oil. Had oil changed and new oil filter installed and in less then a week it burned out 3 quarts, again with no low oil warning at all. Motor stalled at intersection and had to cool down, oil was again added and lower engine knocking was present. Meanwhile had a mechanic inspect it and diagnostic done and lower bearings are knocking. Vehicle has had this issue for over 4 years and never mentioned to us until now after 100,000 miles. 2019 is when this oil burning issue began. Hyundai dealer serviced this several times and never mentioned the reason for the knocking other then it was low on oil. After breaking down in a busy intersection had to be pushed off road and waited for engine to cool down to add oil and knocking continued.

Minor vibration on front end axle during initial acceleration started early during ownership, but increased over time with mileage and usage. Took into dealership where purchased for diagnosis, but could not isolate cause. Problem worsened over next couple of weeks, so took it back in to same dealership. Finally diagnosed the problem to be a missing circlip ("c" clip) that holds the cv axle in the transmission case. Without it, the axle itself was working its way out of the transmission case, and vibrating because of its looseness. Researched the problem and found that full separation of the axle from the transmission could result in uncontrolled behavior of car, and inevitable accident or worse. This was a manufacturing/assembly error, and could be a systemic problem in the assembly process. The repair was performed by the dealership under warranty, but this could present a dangerous risk to other 2017 Sonata purchasers, so I write this complaint as both a civic right and a responsible citizen. When discussing this issue with a Hyundai representative, I was told in blunt and no uncertain terms that the problem was resolved and there was no further action or discussion that was necessary. Our prior 2011 Hyundai's engine had seized at highway speed, and my wife lost all power steering and braking. Despite safety issues with both 2011 and 2017 Sonatas, there was no acknowledgement nor admission of accountability. I would like to be reassured that this axle circlip problem is acknowledged and rectified, as the greater safety of Sonata owners may be at risk. We personally now feel unsafe in the Sonata model, and only purchased a second one under the assumption that lightning doesn't strike twice. . . This is not so. . .

My vehicle was in park on my street. My husband was in the passenger seat. I exited the driver side of the vehicle and opened the driver side rear door. I kneeled on the seat to reach behind the passenger side seat to grab my laundry basket. The car began to roll backwards. We hit a vehicle directly behind us and ended up in our neighbors yard. We contacted the police and a tow truck was sent. The tow truck arrived from joyce's towing on mt. Nebo road in pittsburgh PA. The tow truck driver noticed that while the car was in park the wheels were spinning. The body shop in which we took our vehicle to, is having an issue trying to duplicate the problem. In the meantime, I do not feel that our vehicle is safe, and do not want to risk this incident happening again, being that it was an issue in 2011-2014 Hyundai Sonatas.

Tl the contact owns a 2017 Hyundai Sonata. While driving various speeds, the accelerator pedal was depressed; however, the vehicle hesitated while making a left turn. There were no warning indicators illuminated. The vehicle was taken to gerald Hyundai of north aurora (209 hansen blvd, north aurora, IL 60542, (877) 781-4106) and napleton's valley Hyundai (4333 ogden Ave, aurora, IL 60504, (630) 851-2500) to be diagnosed, but the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was contacted and provided case number: 15823638. The contact was referred to the local dealer. The failure mileage was 15,494.

Driving to work vehicle lost power in parking garage, during busiest time and lot of traffic in garage. Car felt like it was coasting, pressing the gas pedal and nothing, then floored the pedal and it revved up enough to get me up the ramp into a parking spot. Engine warning light came on. Thankfully this didn't happen on the freeway. Towed to dealership, they don't know what is wrong, the car is still in the shop.
