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.

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.

The engine is ticking as well as vibrating. Looked on the website to see if there were any recalls for this which every year other than the 2020 was having this issue - spoke with a diagnostic shop and they said have had newer models with the same situation and was able to turn over to Hyundai - which they replaced with no charge to the owner. It happens when it idles as well as when I am on the interstate.

The car has issues with starting, and accelerating. Dealerships have zero availability for weeks out to provide any sort of diagnostics, and are unable to assist with this issue. The following email was sent to Hyundai Customer Service: I am currently leasing a 2020 Hyundai Elantra.? In July of this?year, the car suddenly had trouble accelerating.? Being due for an oil?change, and wanting to get the?engine codes read, I contacted my local Hyundai dealership, and they had no availability for weeks.? I used a local service station to have the codes read/get the oil change, and the car continued to have difficulty (I am attaching the BlueLink reports on said codes).? I was finally able to bring it in to the local dealer who cleared the codes, and said they were the result of "not having enough oil."? The car drove well until 11/27, when the car started to sputter, not allowing it to accelerate?properly, and with multiple error messages, including a flashing engine light.? After contact my local dealer who I first used in July, they said "it is probably low oil like last time, these cars are known to burn oil quickly."? I again?brought it to my local service station for the oil change, and for a NYS inspection.? As my car is under 15k miles, and up-to-date with oil changes, I would imagine it would pass said inspection.? It did not.?

They advised me that they ran scans to determine what the problem was. On one occasion they stated a censor needed replacing, and later told me that was done. Thereafter, on Friday, August 26, 2022, I was positioned to bring the car in again because the check engine light remained on, and additionally, another dash light came on causing a loss of power and the car to stall. The dealership told me they ran another scan and found metal shavings in the engine, and the engine would need to be replaced.
