Unintended acceleration is happening. After about 15-30 minutes of driving, accelerating from a stopped position becomes very difficult in the sense that the vehicle does NOT accelerate when gas pedal is pressed. This can be extremely dangerous as you do not know when the vehicle will no longer accelerate and could get hit when crossing an intersection or turning onto any road at all. ESC warning light came on today and vehicle will no longer start but goes into auxiliary mode. This is not the first time, second, third, nor even 5th time a report on this vehicle has been made and with each report more issues are arising with seemingly NO fix in sight.

One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. I took it to the Hyundai dealership and they told the me senor is off alignment and it will cost $500 to repair because they have to remove the entire bumper. I have seen on Hyundai forums this is a common problem.

When driving at 55MPH with cruise control on, the car suddenly accelerated to 75MPH, this happened on the open road and was able to keep under control. Auto has less than 10,000 miles. I will be contacting Hyundai customer service for a case number on this incident. First indication of a problem was cruise control, auto braking failed iin June of 2023. This follows a replacement of defective front radar unit by Hyundai which was replaced at 8295 miles on July 26, 2023. This problem first occurred in late June/early July of 2023. There was no warning.

Driving on highway, dashboard reported "Check Forward Safety System" and "Check Smart Cruise Control System". The car then disabled both while I was driving. This has happened 6 times to me. The first time I brought it to dealer and they stated it was a calibration problem. They reset it and I had no problems for a while. The problem has occurred 5 times more and will stay on for about a week or so and then just go away. It works again and then occurs again. So, it is intermittent and recurring. Each time the diagnostic code reported by the software to my phone is C162078. I see the 2018 Kona had the same exact problem and a software update TSB was put out there.

The forward collision warning stopped working several months ago. We gave the (leased) car to the dealer for repairs after 4 weeks of waiting (parts, etc.) We were told the car was fixed and ready for pick-up. I drove it from Baltimore to DC for a meeting and on several occassions when car stopped abruptly in front of me on the highway it did not give a warning, when I tried using cruise control, it would not engage because the conditions for doing so had not been met - same message I had when foward collision was not working. It's pretty clear that this was not fixed and instead they must have changed the messaging so that it does not appear as a warning when you start the car. The feature is really important to us because it has prevented a potentially fatal accident on a winding road in NY state where we found a truck on our lane due to a downed tree on the other lane - the car braked well before I did- which is the point of these safety systems. The dealer is Len Stoler Hyundai in Owings Mills

Forward collision system continually fails. This disables the vehicles cruise control. The vehicle has been in the shop multiple times with no resolution.

Hello everyone. I NEED HELP i have a 2021 hyundai elantra and i have had the same issue for over 10k+ miles and 6 months. My traction control light, (no matter what speed or acceleration/deceleration.) will flicker on and off, make a horrible noise almost as if the ABS is applying but no ABS light comes on, and the pedals will go stiff and the whole car jerks. My 2021 elantra has had a new transmission put into it AND when that didn-??t fix the issue, the wheel speed sensor was replace-?? well if that had fixed the issue, i wouldn-??t be writing this post. after a new transmission, and wheel speed sensors, didn-??t fix the issue the dealership themselves advised me to look into the lemon law being they had no idea at this point what was going on with my car. i have attempted getting my car bought back under the lemon law (Ohio) which my car meets the qualifications being that the issue was brought the the dealerships attention, before the 12 month or 18k (whichever came first) which in this case was taken to them before both. and that my car had been in the shop more then 30 days cumulative (it-??s been 41) and hyundai has denied my request for a buy back, and has told me i need to do more research or get an exterior 2nd opinion. (pretty much a lawyer). they-??ve advised me to -??just keep taking it to the shop and get it fixed-??. the issue is, this does not occur all the time. it is completely random and will do it once in a week and then not again for another 3. but when this happens, it-??s scary. it-??s loud, the pedals go stiff and the whole car jerks. accelerating or decelerating. the dealership will not replace something if they cannot duplicate the issue which is also a reason it-??s taken so long to get any sort of answers. i have multiple videos, the service MANAGER, has rode in my car with me while this issue has occurred and stated himself my vehicle is unsafe, and i should not be driving it. i need help!

My vehicle was slowing down and was halfway into a parking spot. Then, it suddenly accelerated, jumped over commercial parking blocks, and ended up stopping after hitting a wall. My brake was not working at that moment. I initially reported it to Hyundai USA (as a dealership doesn't seem to consider this a serious issue at all), but decided not to let them investigate on their end based on their slow and unprofessional responses.
