2020 HYUNDAI ELANTRA Complaints

TOOK OUR VEHICLE TO THE LOCAL HYUNDAI DEALER ON 1/30/2024 TO HAVE THEM LOOK AT THE ENGINE AS MY REGULAR MECHANIC STATED THE "ENGINE WAS KNOCKING" AT THE MOST RECENT OIL CHANGE, AND GET IT TO THE DEALER AS IT SHOULD BE UNDER WARRANTY. TURNS OUT IT DID NEED AN ENGINE WHICH THEY REPLACED YESTERDAY FINALLY, HOWEVER WHEN THEY TOOK IT FOR A TEST DRIVE THEY STILL HEARD NOISES. THEY EXAMINED IT FURTHER AND TODAY THEY NOTIFIED ME IT ALSO NEEDED A NEW TRANSMISSION. THIS VEHICLE WE HAVE HAD SINCE WE BOUGHT IT NEW IN JANUARY OF 2021, HAD LESS THAN 10K MILES ON IT WHEN WE TOOK IT INTO THE DEALER ON 1/30/2024. THIS IS ABSOLUTELY UNACCEPTABLE. THANK GOODNESS I HAD ALL MY RECEIPTS TO PROVE REGULAR PROOF OF MAINTENANCE ESP SINCE I HAVE A REGULAR GUY AND DID NOT HAVE IT DONE AT THE DEALERS.

Started noticing my 2020 Elantra was "jerking", "lurching" while in motion of driving. RPM would shoot up. A handful of times I would be losing power and almost not make to where I was headed. Starting/Turning from a dead stop, I would have no power and then suddenly it would surge and then I could get up to speed. I did not have any indication before hand or while driving. I did not have any lights come up, while driving or when it did the startup check when turned on. I barely made it to a Auto service, he drove it from one end of the parking lot to the other, then whipped into a bay for him to look at. I was told it was the Transmission, specifically CVT slippage and he suggested I do not drive home.

I took the vehicle in for it's regular oil change on 1/19/2024. My regular mechanic stated to me that "the engine is knocking, you need to get it to the dealer so they can fix the issue as it should be under warranty." He finished the oil change and we came home and immediately made an appointment with our local Hyundai Dealer - that appointment is on 1/30/2024 at 9 am. This is an extremely concerning issue as it affects the whole vehicle and the ability of it to be driven and last a long time. No warning lamps, or messages occurred for this issue, only the statement by my regular mechanic. I want to make sure this is documented in case Hyundai tries to get out of fixing the issue. This could be a very expensive problem. The appointment was made for the 30,000 mile service, but I will make sure they are aware of the engine issue when I take it in as well.

The contact owns a 2020 Hyundai Elantra. The contact stated that the vehicle failed to start without approximately 15-20 attempts. The vehicle had since failed to start completely. There were no warning lights illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the starter had failed causing the engine to seize. The contact was informed that the engine needed to be replaced. The vehicle was then towed to the dealer and the contact was informed that there were two open recalls on the vehicle. The vehicle received the recall repairs however, the starter was not replaced. The manufacturer was made aware of the failure and the two unrelated recalls were confirmed with the VIN. Additionally, it was also confirmed that the replacement of the engine was no longer covered under warranty. The approximate failure mileage was 87,000.

The engine at 41,000 miles had a catastrophic engine failure on December 22, 2023. It blew up with all maintenance done on time. I bought this car on February 28, 2023 and I heard the same knocking noise a week after the dealer kept my car for 36 days and was unable to re-create the problem. The car has now been in the shop for 15 days and I believe it is a complete lemon. I do not trust the safety of this vehicle and I see others are filing complaints ago Hyundai and Kia for the same thing I want to be reimbursed and my loan canceled.

I keep replacing the lights the daytime and the headlights and they’re constantly going out . Many of people have this ongoing problem.

Daytime running lights faulty from manufacture. Had to replace headlights once already and now out again. Hyundai has made this headlight assembly non repairable and charges over 1k for a replacement.
