What owners say about the power train

Verbatim from NHTSA complaints, newest first
“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.”

“The contact owns a 2020 Hyundai Elantra. The contact stated that while driving at various speeds, the RPM elevated to a high level while depressing the accelerator pedal. There was no warning light illuminated. The failure persisted while depressing the accelerator pedal without a warning light being illuminated. The contact used a code reader to diagnose the vehicle; however, no fault codes were found. The vehicle was taken to a dealer and was diagnosed with transmission failure. The vehicle remained in the possession of the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was 70,000.”

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.

“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.”
