ENGINE, UNKNOWN OR OTHER
When driving the car on the highway - "check engine - hybrid system" warning lights come on and indicate hybrid system issue and to shut car off immediately. Extreme safety issue as the car goes from highway speeds to 35MPH almost instantly. This has happened seven times now and Hyundai keeps indicating that technicians are following engineering guidance in fixing the issue related to the knock sensor. The seventh occurrence happened on May 23rd of 2023. First one was in December 2021. As Hyundai is unable to correctly fix the issue I have repeatedly asked for them to replace the car since it is an extreme safety issue but they will not do so. Still waiting for diagnosis of the latest occurrence from May 23rd. Hyundai does not acknowledge that this issue is of safety concern and just indicates that the issue has been fixed each time it occurs.

My 2013 Hyundai sonatas engine seized up while I was drive it. Lucky, I made it to a parking lot before it completely just died. The car only has 114,000 miles on it and I’ve only had it for a year and a half with no other major issues.

STEERING
I had the steering coupler replaced on 5/9/22 at the dealer. Now the steering coupler is clunking again & the dealer will not cover the repair. My car is now out of the 10 year warranty and the replaced steering coupler only had a 1 year warranty on it. This part should not have to be replaced yearly.

VEHICLE SPEED CONTROL
On 5/30/23 while in traffic I pressed the brake to slow down and the car kept moving forward. I pressed the brake all the way down and I was still unable to stop the car from accelerating. I rear-ended the vehicle in front of me. My car is currently being inspected by a mechanic that my insurance company recommended.

ENGINE
The engine seized while driving on the highway. The car is currently at the dealership. It started making gurgling noise and slowed down while driving. This happened in the middle of the road while driving, putting me and other drivers at safety. The dealership inspected the car and they said the engine seized. There is a recall and multiple complaints concerning this car. They have now said that they will not honor the recall and repair the car because I don't have all the oil change documents. I bought the car as a used car and have my documents since I have owned the car. They are taking care of the issue that is definitely manufacturing issues.

ENGINE
My cvvt is bad, the car is only 7 years old and has had on time oil changes. I bought the car from the dealership not even 2 years ago, on september 3, 2021. The cvvt is bad already. I do not speed, and I take good care of the car. There is no reason this part should have gone bad on so many cars this far. Please recall this item as it has gone bad on multiple vehicles, as well as my car constantly smells like it’s burning due to this issue.

ENGINE
Started the vehicle and shifted into gear and the vehicle started to shake and vibrate. The engine was knocking and running very poorly. Within a minute the service engine light came on. We were able to get the vehicle back in to the garage. I opened the hood and checked the oil. The dipstick was dry. The end of the dipstick appeared to have burnt oil on it. I took some pictures and a video of this. I did some simple online research and found numerous cases an articles pertaining to this situation. I have had all my routine maintenance performed at a dealership since it was purchased. I added 3 quarts of oil and now the dipstick reads half-way between Low and Full. I started the vehicle and the engine still shakes and runs poorly. The nearest Hyundai dealer is over 20 miles away and I don't think the vehicle will make it that far. Do I even have any other options than trying to "limp" the car there and possibly mess more things up in the process?

STEERING
The steering wheel completely locks up while driving/turning. It almost as if the power steering has gone out and it's near impossible to turn the steering wheel. On several occasions while backing out of our driveway, the steering COMPLETELY locked up. On few other occasions, it locked up while driving and making a turn. 2 times it locked up randomly while just driving switching lanes at 25Mph. Resolution is to stop the vehicle, turn it off, wait a minute or two and turn it back on to reset the power steering and then it works until it happens again. There are hundreds of reports that can found online for this issue happening to this year and model car (2017 Hyundai Sonata). This is clearly an issue. This is EXTREMELY dangerous as I don't have to explain what happens when steering wheel gets locked up while driving. This has happened SEVERAL times now and dealer was no help when we initially took it in as they could not "replicate" the issue as it is intermittent. Please look into this issue with Hyundai. This is unacceptable. Will action only be taken when lives are lost because of it? Is that the cost to have this issue looked in to? Thank you
