2017 HYUNDAI SONATA HYBRID Unknown Or Other Problems

Literally for years I have been taking my car in to Rick Case Hyundai with the complaint of smelling gas even when the car was parked for long periods. Each time they said they fixed with different items. Gas cap, a part on the catalytic converter, etc. The problem never resolved but I noticed it only happened when the tank was more than half full. I got a video of gas dripping out underneath and took the car to Rick Case and gave them the video. My car has been there ten days because they first tried to say it was a seal on the fuel pump. This time I said that seems unlikely cause that only happens when tank is full and persists even after car is parked many hours. Now they report they found a pinhole leak in the gas tank. I will upload the video if this form allows. This does not appear to be a pinhole leak to me. I first noticed this around 2019. Unfortunately the video is MP4 and I cannot upload it.

My 2017 Hyundai Santa hybrid limited it all started with 11 icons appeared on the dash took it to Hyundai dealership Gainesville to be fixed in July of 2024 dropped it off Wednesday they emailed me with a price of 1563.70 I okay it to be fixed. I picked it up that following Saturday no sooner after leaving halfway home the check engine light came on took it back the following Monday they pulled it in the shop no more than 15 minutes later they pulled it out said they fixed it said if it should happen again to bring it back shortly after leaving check engine light came on again took it back to them and fixed it left check engine light came on again so I took it to Tallahassee Hyundai dealership they changed cabin air filter and engine filter we left the check engine light came on again so we took it back to them again and they found nothing . Then the check engine light was still on then the car wouldn't start so I had to pay to have it towed to Hyundai dealership of Gainesville again told them now the car won't start and it's been there since October 20 2024 spoke to them many times I still haven't gotten any one that can seem to fix my car they don't return phone calls just give me the run around it's my only car I have never heard of a dealership that can't fix there own car they sell . I'm getting nobody that is willing to help me and the car is not paid for im so upset is this the kind of business you provide to your customer's.

This is the seventh occurrence of complete loss of power while driving on the interstate. The hybrid system warning activated, followed by the engine shutting down, and all dashboard lights illuminated with alerts indicating "Shut Off Engine/HEV." An 18 wheeler was pulling out from the shoulder as I was losing power and barely missed getting crushed. The former problems have all been at interstate speeds with similar accident avoided. The service history clearly demonstrates that Hyundai has repeatedly attempted to address this issue by replacing numerous critical components, including the engine, transmission, knock sensor, battery (three times), integrated brake actuation system, and smart cruise control, among others. Despite these extensive repairs, the problem persists. On this latest occasion, less than 4,000 miles and four months since the last major incident, the dealership has proposed replacing the intake manifold, EGR valve, HSG belt, and spark plugs. The belt was changed less than 20K miles ago. and I believe the spark plugs were as well. Each time my vehicle experiences this issue, it is out of commission for weeks or even months at a time, causing significant inconvenience and raising serious safety concerns. I no longer trust this vehicle and I don't believe the many recalls have successfully addressed the root cause of issues with the 2017 Hybrids.

In May, the engine completely failed as I was driving on the freeway, without cause. It had to be towed to the dealership where luckily the engine was replaced under warranty. Less than 6 months later, the HEV and CEL warning lights came on as I was commuting to work via highway. The car was very low powered, hard to accelerate, and immediately decelerated whenever I started to let off the gas pedal. It struggled to go at or above 60-65 mph. The freeway speed was 70 mph and it was a safety risk for the car to power down. Dublin Hyundai could not replicate the problem, simply recharged the battery and said I was good to go. Less than 1 week later, the exact same thing happened as I started on a road trip. I had to return the car home and get it towed to Stockton Hyundai for diagnosis. This is car is only 6 years old, has been routinely maintained, and just hit 100k miles, for which Hyundai is denying any repair assistance even though there is a lifetime hybrid battery warranty.

I first experienced HEV hybrid system issue back in 2022. I took my sonata to the dealership which they had over a month to try to fix the problem which they did for the time. Now a year later I’m back with the same issues and the dealer basically saying they can’t see my car for a month then don’t know how long it’s going to take to fix the issues if the even. Nobody can really tell me what’s wrong with my car. This the second time it’s been a safety hazard while driving on the interstate and the system malfunctions causing a hazard to me and drivers around me because the vehicle has basically cuts off rapidly slowing the vehicle down

This issue has happened twice in one month on my Hyundai sonata hybrid that I’ve had for less than 3 years. It is a 2017 model. While driving on the interstate, the car will stop accelerating and all warning lights will come on along with “Check hybrid engine. Turn off engine”. The dealership has yet to find out the problem and cannot tell me what the issue is both times I’ve brought it in (it’s had ti be towed both times). I cannot afford to keep paying for repairs on an almost new car along with the safety concerns of driving it. I am attaching pictures of both times it happened- noting that it is the same warning each time. It looks like multiple owners are having this issue and none has yet to be resolved.

My wife and I have been having an intermittent but constant problem with our steering mechanism which our dealer says they cannot replicate and therefore cannot resolve. This constant problem is one that MANY Sonata Hybrid owners have reported online. Our experience is having the steering wheel seize, flashing lights during which the red steering wheel icon with an exclamation point remains on. Our experiences have been in our mobile home park when we are turning left. The last two incidents were when we were blocking our street and vehicles could not pass. A prominent feel in the steering wheel of clicking, clunking, and play in the wheel accompanies these incidents. I had to, as others, to turn the car off and restart to carefully, amidst clicking and clunking, to return the car to our driveway where it will sit until we take frontage roads to our dealer. We recently received a notice from Hyundai that the steering wheel mechanisms' warranty has been extended 15 years from the ending date of the original warranty. The notice indicated that our Sonata Hybrid "may exhibit reduced power steering assist and/or motor driven power driven steering (MOPS)." We believe this is suggesting that MANY complaints have been sent to various authorities regarding this same issue. We now have a much delayed (due to our dealership's backed up service appointments) appointment to again address this problem which they say is not happening because they cannot replicate it. Many online comments indicate that people are scared that themselves, loved ones or others will be involved in a fatality due to this "intermittent" problem. We could not find a Hyundai Regional Manager with whom to correspond. We feel abandoned by Hyundai but hopefully not by the NHTSA.GOV. We are scared and disappointed. Is Hyundai really "committed to providing vehicles of outstanding quality and value" as its August, 2022, EXTENDED WARRANTY NOTIFICATION said. Please help. Hyundai dealers won't.

The contact owns a 2017 Hyundai Sonata Hybrid. The contact stated that while driving at an undisclosed speed, the check engine and ABS warning lights illuminated. Additionally, the check HEV System message was displayed. The vehicle then lost motive power and was not able to restart. The vehicle was towed to the dealer on two separate occasions. The dealer replaced the engine coil and battery; however, the failure recurred. The vehicle was taken back to the dealer and the dealer performed NHTSA Campaign Number: 21V749000 (Exterior Lightning, Electrical System) however, the failure recurred. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 75,000.
