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.

On February 23, 2022, I was involved in an accident with the Hyundai Elantra, Vin# [XXX]. The vehicle-€™s brakes failed, and I struck a Blue Ford Escape from behind with a speed of approximately 37 mph. On January 13th, I made an appointment with the Napleton Valley Dealership in Aurora, IL. where the vehicle was purchased complaining about the brakes and drifting into an intersection on Route 83 and Sycamore Rd. for 20 feet. The mechanic checked the brake pads, drove it for 3 miles and deemed that the vehicle-€™s pads were adequate. It was determined that no problem was found, brakes checked good, all within specs. (12,818 miles). The vehicle was towed from Hinsdale, IL. to Dekalb, IL., approximately 85 miles to my residence at 612 Magnolia St. Dekalb, IL. 60115. It was then towed a distance 3.2 mile to Dekalb Body and Collision, 116 Industrial Dr., Dekalb, IL. 60115. Since then, it has been back in the dealership for issues related to the engine, taillight, and a series of additional Inspections verifying that the codes were working. On March 8th when I visited the Body Shop & Collision I was told to -€œhire an attorney-€. The vehicle was defective and should have never been on the streets. Preliminary findings on vehicle were concerning as far as airbag sensor was impacted but no airbags deployed at the time of impact. Upon vehicle arriving at our repair facility, we conducted pre-repair scan vehicle codes read as followed (see picture). Impact sensor was highly damaged, expected to have had airbags deployed at the time vehicle was impacted. Vehicle received front-end damages which resulted in needing the following parts replaced, front bumper and grille. Crash impacted the front bumper reinforcement resulting in some hours needed on frame machine to align front-end. Engine cooling system was impacted resulting in the need to replace radiator assembly and A/C condenser assembly. Hood and both front lamps are needed to be replaced as well.

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.

The car was brought back to the dealership after a few months after noticing that the steering wheel would shake and the car would jerk when brake was applied to slow down. In normal street driving as well as during highway driving. The dealership since it was under the warranty replaced the front rotors and the brake pads to solve the issue. Within the one year of purchase of the car, it was once again having the same issues of steering wheel shaking and the car jerking motion back and forth. When he car was brought back to the dealership they said that it was not under the warranty and that they would not address the issue And that if i wanted it to be fixed i would have to pay out of pocket I think that there is something wrong with either the rotors or the braking system that is casing this shaking and the car jerking when trying to slow down, and it should be addressed and investigated further.
