2021 HYUNDAI ELANTRA Complaints

Car will accelerate when pressing on brakes. Once car is able to turn off, the problem does not repeat. This has occurred at least 3 times with the same car and random times while on the road. Dealership is unable to replicate the brake issue every time the car is brought in.

The contact owns a 2021 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the vehicle overheated. The vehicle was taken to the dealer, who informed the contact there was a crack on the radiator. Additionally, the dealer determined that the failure was possibly collision related; however, the contact stated that the vehicle was not involved in a collision. The manufacturer was not made aware of the failure. The failure mileage was 39,573.

The contact owns a Maxi Cosi Coral XP car seat, Model Number: IC313FNDV, Manufactured: 10/09/2020. The car seat was being used in a 2021 Hyundai Elantra. The contact stated that the seat base failed to separate from the stroller when the release handle was pulled firmly. The contact stated that several attempts were needed to remove the car seat from the stroller. The child was not in the car seat during the failure. The contact later received notification of NHTSA Campaign Number: 23C002000 (Child Seat), which she related to the failure. The manufacturer was notified of the failure. The car seat was not replaced.

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.

I was driving using cruise control when suddenly I got the error message “Check Forward Safety System” and my cruise control no longer functions. Turned car off and back on and message is still there. As the emergency braking system stopped working, this is a safety issue. Have not taken it to dealer yet. The car has other software/electrical issues related to the reverse camera and Apple CarPlay. There seems to be several software issues with this car.

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)

The contact owns a 2021 Hyundai Elantra Hybrid. The contact stated that on multiple occasions while the vehicle was idling, right before releasing the brake pedal, the vehicle did not immediately accelerate forward while depressing the accelerator pedal. Additionally, while driving at various speeds, the vehicle experienced unintended acceleration. After stopping and turning off and restarting the vehicle the failure was self-corrected. The vehicle was taken to the local dealer who was unable to duplicate the failure or detect the cause of the failure. The manufacturer was also notified of the failure, but no assistance was offered. The failure mileage was 2,000.

Check forward safety system is on all the time, dealer refusing to fix it. Did have airbag recall repai done yesterday Had computer update done on car.

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.
