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.

I picked up my Hyundai Elantra n-line today 12/1/22. My car was at the dealership for almost 3 weeks for transmission judder (shudder?) issues and they claim to have fixed the issue with a TSB (Technical Service Bulletin) from Hyundai with some snap and cable and additional work that was not disclosed. After picking it up and driving only 3 blocks my car went berserk where all dummy lights went on, the car's engine revved to redline, took off and suddenly the front wheels turned left (due to the avoidance features of the car perhaps) and I was able to pull the emergency break and stop the car. The car stopped luckily and if the e-brake did not work I would have ended up hitting the rear corner of a car and into a house. While the car was stopped, it was still on (unable to be turned off), all lights blinking including dummy lights and the car was showing still in DRIVE mode even though the revving stopped and the car was dead stop. After 10 minutes I was able to turn the car off (push button). Dealership dispatched a tow truck and now my car is back at the dealership for investigation. NOTE: TSB is something that is a known issue from Hyundai but not yet to the level of an official recall is what I was told by the dealership.

The contact owns a 2021 Hyundai Elantra. The contact stated that the vehicle was taken to the dealer for an unknown recall repair and for an oil change. However, while driving at an undisclosed speed after the services were performed, there was smoke coming from the exhaust pipe and the engine oil warning light was illuminated. The contact noticed that the engine oil had leaked onto the roadway while driving. Upon inspecting the vehicle, the contact noticed that the engine oil drain plug was missing. The dealer was made aware of the failure but provided no assistance. The vehicle was then taken to a second dealer, Columbia Hyundai (10981 Montgomery Rd, Cincinnati, OH 45249). However, the vehicle was not diagnosed or repaired and remained at the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 15,500.

At about 11 months old my car suddenly seized while attempting to enter the highway. This came with no type of warning from the vehicle until the car had stopped and then every light on the cluster came on. I was fortunate not to be rear ended. The car was towed and 2 days later the dealership called to tell me there were no errors and NOTHING WAS WRONG with the car. I told them what had happened and they called later that day and I was informed that they needed to install and entire new engine assembly. The car only had 7000 miles on it and should not need a new engine. There is some major design flaw with this car which poses a safety issue. Additionally I looked at my service records for the car and it looks as if the dealership is trying to cover up the fact that a new engine was placed in the vehicle as it is listed as routine maintenance. Please look into this and contact me if needed

On multiple drives the car has "lurched" or accelerated when foot was NOT on the accelerator pedal. These were minor issues, but unnerving when pulling up to park near a structure. Today 3-23-22 I was driving and after about 1 hour of normal operation the car began to accelerate while pressing the brake, and decelerate while pushing the gas. The engine was revving and then slowing down opposite of what would be expected. This is a hybrid vehicle - it felt as if the gas engine was supposed to be spooling up to charge the battery but instead was feeding power to the wheels. there was no engine light illumination from this. I restarted the car and it seemed ok. Honestly, this was scary - trying to move from one lane to the next to an exit to safely exit the morning rush hour freeway. I had to keep my foot HEAVY on the break to make it slow / stop. On two other previous drives the vehicle "lurched" / the car "bucked" once or twice and then the gas engine would not re-engage. the MIL came on, and the car drove on battery power only. I drove off the road, restarted, and the vehicle worked fine. By the time i got the car to the dealer the MIL had cleared and they were unable to pull any codes and deemed the car safe / found no issues.

On 1/27/2022 my daughter was driving home from school in her 2021 Hyundai Elantra SEL which was purchased new on 6/19/ 2021 when at 5600 miles on the odometer a message came on the instrument cluster which read put car in neutral and turn off engine, when it was safe to do so she stopped the car and turned it off in the middle of a two way road because there was no shoulder and no place to exit the roadway when she tried to restart the car the engine would not crank or turn over to start the car so she called me and I called a tow truck while she was waiting vehicles behind her where forced to go around her car when it was safe for them to do so, the tow truck came and took her car to the dealership where she purchased it two days later they called and informed us the engine was completely seized up and that they would have to replace it with a NEW ENGINE despite the fact the original engine had oil and was only six months old with only 5600 miles on it.
