    Daughter was driving her car on interstate, doing 75, in the middle of traffic when the car would jerk and then loose power. The gas petal stopped working and the check engine light would come on. She had to make her way over to the shoulder, without causing an accident. Once car gets shut off and you wait a few minutes, you can start it and drive it home. This has happened about 4 times now. We are lucky that this hasn't caused an accident! This last time (yesterday), the check engine light stayed on and we were able to hook up the dianostic reader and it read the code for the crankshaft positioning sensor A circut. It says online that this is a common problem with that car and is very dangerous. How is this not up for a recall? My daughter is scared to drive her car.

    I recently purchased a Hyundai Sonata hybrid with 132K miles on it and it has been driving fine for at least two weeks until a few days back the car has been displaying a recurring alarm on the dashboard telling " hybrid system warming! Safely Stop and Do Not Drive " now as soon as I turn on the vehicle the alarm comes on immediately. It's been a week since the car is technically inoperable because if I attempt to drive the car it makes this horrible grinding sound which is terrifying considering if I drive like this it would probably cause more damage to the car, and I have look for information on this issue and have found many of these cases over the years that I can relate to but unfortunately there's no a recall of this problem. I'm taking the car to the dealership soon but I don't have any hopes that they will find a permanent fix for this since nobody has apparently. I'm just trying find some help with this issue. So far I just have lots of regrets about this purchase and just hoping I can find some help with this matter.

    Our 2012 Hyundai Sonata Limited had some kind of seat belt recall done in 2017. Not sure what as we were not given any documentation. We are having problems engaging the Driver's seat belt that started in the last month of 2022. Hyundai keeps referring us to the local dealer to see if indeed it is part of that recall. The local dealer insists on charging $160.00 inspection fee, if it's covered Hyundai will be charged. A knowledgeable mechanic should be able to sit in the driver's seat and attempt to buckle the belt and know if it is covered, without charging $160.00. Pease help.

    We have had issues with the tail lights of the car not working properly. The lights have had issues with the daytime running lights not working or the brake lights not working. When we took it in they said that there was an issue with the wiring harness. I also noticed 4 separate hyundai sonata vehicles with they same body style in the last 2 days that appeared to be having the same issues. I think it is something to be checked out to see if there is an issue there because it is a major safety concern.

    While driving with foot on accelerator, acceleration/ current speed will randomly just stop. 1-1- Once i fully release the accelerator and then reengage the accelerator problem goes away. This is very random as to when it happens, and will happen multiple times in a row some times... and other times happens once and doesn't the rest of the trip. This seems to be more amplified occurrences when it is cold. 2- Safety is put at risk. 3- Not gone to dealer yet. 4- No inspection yet. 5- No warning messages.

    Driver's seat belt takes 3 to 5 times for it to engage. A recall was done for the front driver's seat seatbelt. Campaign recall was done in December 2017 at Chapman Hyundai Phoenix.

    gasoline engine. yes, it is available. This vehicle has broken down and left me stranded at the side of the road more than a few times. It has failed on the Interstates , as well as local highways. The dealer refuses to replace the faulty engine. No warning lights have come on with regard to the gasoline engine. Ever since I purchased the vehicle, it sounds like there are marbles in the gas engine when its running at low rpm. The oil leaks are extreme and getting worse. It is smoking badly. I just do not have any more money to pour into this vehicle. I want a new engine from Hyundai.

    When I start the vehicle in the morning I leave the neighborhood going around 15mph and the car loses power. I have to let off the gas completely then reapply but it still continues to studder. I applied the slapstick sift mode and noticed it does this in first and fourth gear. In automatic you can’t see it
