Sometimes upon depressing the accelerator the engine does not respond. The car does not move in a traffic situation. Putting the car in park, shutting it down and restarting makes it go away for a while. Getting on and off the highway is especially dangerous. This has happened intermittently for the past 1-1/2 years. The dealer says that they cannot reproduce the problem. So, they cannot repair it.

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

While driving in stop and go traffic this morning (02/06/2023), at approximately 8:45 am, my Hyundai Elantra began accelerating on it's own. I applied the brakes and the car behaved as though I slammed on the brakes. The acceleration and braking issues happened multiple times during this drive. After the first incident, I shifted the car into neutral, (when it happened subsequently) until it quit accelerating, which was a couple of seconds. I have scheduled service at the Hyundai dealer for tomorrow morning (02/27/2023)

Our problem started a few months ago. At first, we thought it was just a fluke, but this issue has happened too many times to be so. The issues are, the car does not accelerate when we depress the accelerator, we see the tachometer move, but the engine is not actually accelerating. Then at times it will accelerate on it's own, while sitting at a red light, the car tries to move forward despite having our foot on the brake, it acts like we are trying to push the accelerator and the brake at the same time. Even worse, while driving, the car will go into accident-avoidance mode, even though there is nothing in front of us. There are no errors or codes populating on the dash.

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 -€œjust 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.
