This vehicle recently had a new engine and new transmission installed into it in February of this year. Less than 10K miles on it. The engine light came on on 4/12/2024 and I took it back to the dealer immediately. They called me on 4/15/2024 stating that their engineers and techs had had problems on the transmission recently installed on it due to manufacturing and/or faulty parts, and to replace that transmission with a new one. Still waiting to get the vehicle back at this point in time.

No. There is a check engine light that appeared. To continue after the questions, Max Hyundai of Manhattan, address: 8020 US-24, Manhattan, KS 66502.

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.

Transmission studders and looses acceleration while driving

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.

I bought the car from the dealer when the car had a total of 12,000 miles on it the transmission would lunge the car forward at speeds around 70 mph. It made driving the car unsafe on the highway as I couldn't tell if it was going to lunge forward and hit the car in front of me, and I got it to the dealer. It was under warranty and the dealership tested it and said it needed to be replaced. When I got to 18,000 miles the new transmission had a similar incident and the dealership tested again and said this new transmission needed to be replaced completely. It is still under warranty and they will replace it in 3 weeks. I am going to be on the third transmission with a car under 20,000 miles. The transmission was only inspected by the dealership, and they told me that they do not know what was wrong they just pulled out the bad one and put in another, they did not take it apart to figure out what the problem was on the first one that needed to be replaced. I still have the car and can be inspected before I drop it off at the dealership May 6th. There were no warning messages on the dashboard or any other problems with the car. Information below is on the first incident, the second incident started around February of 2023.
