2020 Hyundai Elantra Powertrain & Transmission Problems

I see there was a P0420 error code related to catalytic converter oil consumption recall, but when I put in my VIN it said no recalls. This is for a 2020 Hyundai Elantra 2020. The problem comes and goes and was able to be reproduced or confirmed by a dealer Hyundai. The warning lamps, messages comes on frequently and was reportedly fixed charges $2000 for a sensor. I the code and it is all over the internet that it is a recall.but does not show up with VIN.i need assistance with getting this fixed at the dealer

Was driving car after a recent oil change. The oil change was performed early because the car was ticking and found oil to be low. Was going to take into dealer to be looked into but the car made a loud sound and stopped immediately and turned off. Luckily I was not driving too fast but had I been this could have posed a risk to myself, my passengers and other drivers. This complaint is consistent with prior engine failure complains of other Hyundai models. The Elantra has yet to be investigated. The maintenance lights that came on have only been for a high mount break light and low tire pressure. I did not get a low oil or oil change needed alert.

Vehicle was recently purchased and brought in to service recall 22-01-030H (TCU Update and IVT Replacement) Fred Bean Hyundai of Langhorne (1106 E Lincoln Highway, Langhorne, PA, 19047) did the software update, but refuses to honor the IVT replacement as part of the recall, despite the transmission not working and needing to be towed to the dealership. They are attempting to charge me a minimum $5000 to replace the transmission, despite the replacement being covered under this recall campaign. Please contact me and advise if I should pay them and am then entitled to a reimbursement or if I should even have to pay them in the first place. They currently have my vehicle and I can't even drive it off-lot due to failed transmission.

I have a code "P0867 Transmission Fluid Pressure" that showed up on my car. Yes. Dealership refused to fix under "Service Campaign [XXX]". Dealership confirmed issue. 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. Refused to fix my vehicle under "service campaign [XXX]". As the service campaign indicates Code P0867 must be present, which it is. As well as a VIN that starts with [XXX], which my vehicle also has. As well as 20MY Elantra's. Which my car falls into that category as well.

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.

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.

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.

Engine seized while going 55-60mph with warning lights only 15 seconds before my vehicle completely stopped on the highway [XXX] ) The engine was replaced by Hyundai along with the manifold and catalytic converter. Vehicle lost all control and power and started excessively knocking while I tried to get to the shoulder but only made it to the right lane. The safety of others and myself were out at risk due to no control of the vehicle. Repair order attached INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

While driving home from my family’s house in the next town over. My car decided to have transmission issues I have had the car car for 3 years so far with now issues until two days ago when I heard a loud pop and my car stopped accelerating. Tried to put it manual mode and I watched the gears shift from 1st to 8th gear in seconds then get stuck in fifth the the check engine light came on. And I was stuck on the interstate for almost 8 hours while I tried to get it to move. The car turned over just fine and revved but no movement like it was stuck in neutral

Loud knocking noise coming from engine. Car unable to be driven. No recall for my particular make and model per Hyundai dealer. Extra consumption of oil and loss of power during acceleration. No warning lights or other messages. 79, 500 miles. Problem inspected by certified auto mechanic.

Transmission failed - car disabled at 85mph
