What 190 owners told NHTSA about the 2020 Hyundai Elantra Gt

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.

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 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.

My check engine light turns on and I’ve taken it to Hyundai to have it fixed and all they do is turn the light off and say it’s a sensor issue but it’s the fourth time the light has turned on I’m worried their is an issue with the pistons or the big e overheating. It’s also brutning a lot of oil that every 3-4K miles the oil drops to 75% full.

There has been a noise coming from my steering column. Its sounds a like rubbing or whirring noise. It only happens at low or stationary speeds. I took the vehicle to a local shop in my area. They diagnosed the problem as the Worm Shaft Assembly ( located inside the steering column). If steering fails while driving, it can a crash and lead to significant injury. While my steering has not failed or led to any accidents, its very possible and a real risk.

On Aug 30, 2023 I went to a Germain Hyundai for the usual maintenance of my Hyundai Elantra 2020 where they checked the condition of the belts and it passed. Fast forward Oct 1, 2023 the timing belt snapped and I had it serviced at Hyundai Great Lakes Dublin. I aired out my concern that it is too early for that belt to break since my mileage is only at approximately 25000, while their manual even says that the usual replacement /maintenance for the timing belt. So I urged them to check what caused it to break. Oct 15, 2023 I was driving off of freeway and we suddenly heard the belt snapped again and the car started to slow down on its own. It was a crazy experience as we were in the middle lane and we could no longer control the speed of the car. The Hyundai service center did not take this matter seriously and only recommended that the belts be replaced again. Essentially, I am in so much concern of my safety now given the situation that even the service center did not take time to figure out what is causing the belt to break and not being able to identify that puts me in a traumatic and unsafe situation of driving this vehicle , knowing it could break anytime.

I’ve had my car for about 5/6 months and it’s been broken into twice and was recently stolen. I haven’t been notified from Hyundai dealership about any recalls. Recently I called Ray Skillman where I purchased the car and a man said that there was a recall on my car a few days after I purchased the vehicle. I haven’t received any letters or notification about this from Hyundai and if they did it could’ve prevented me dealing with my car being broken into,damaged,and now stolen .

Hyundai updated my car with the “anti-thief” software a few months ago. It clearly did nothing because my car was still stolen. They need to install immobilizers for free to really try to fix the problem!

Driving on a road trip, 2.5 hours in. All doors were locked. Drove over a road change from tunnel to bridge, small bump, and dashboard started beeping and flashing that a door opened. Driver side back door (where my child was sitting) opened, air was rushing in. We had to brake ( on a highway bridge to pull over) and unlock door to get it to close again. The door popped open while still locked. Called Hyundai and they said bring it in, but we probably didn't shut it. It was absolutely shut and locked.

When I start off I give my car gas but it does not want to speed up. The rpm drops to 2 and does not move as I push the gas to go to get out of the way of traffic behind me. It goes about 600 ft before it kicks in. Then it runs normal. It's still under manufacture warrenty (3 more years and 20000 more miles unde warrenty). I've taken it to the dealership and they didn't see anything. Said they would have to keep it a couple of days to check it out. It's my only means of transportation but the never have a loner car for me to use till I get mine back. I've seen others with same complaint so why is there no recall. Afraid I'm gonna get hit in the rear due to lack of power. Doesn't do it everyday but has happened twice in two weeks when I've pulled out onto a major highway with heavy traffic. I bought the car used in Jan.2023 with warrenty still on the car. Thought hey great deal! But now I think I bought a lemon.
