The check engine warning light was illuminated. The vehicle was towed to a local independent mechanic, where it was diagnosed with excessive oil consumption, catalytic converter failure, and related the failure to NHTSA Campaign Number: 21V301000 (Engine). The local dealer was contacted however, the VIN was not included in NHTSA Campaign Number: 21V301000 (Engine). The vehicle was not diagnosed or repaired.

Power train

38 reports
“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.”

Electrical system

18 reports1 fire
“Vehicle had several non-starts. I took it to the dealer a couple of times and they could not duplicate the problem. This problem continued for a couple years before I took it to an independent mechanic. Said mechanic put it on a lift and found a loose power cable barely connected to the starter. Luckily this never caused a short, spark, or fire. From my searching online it appears this is a non-infrequent issue with Hyundai's.”

Steering

16 reports5 crashes1 fire
“The contact called on behalf of their son who owns a 2020 Hyundai Elantra. The contact stated that while their son was decelerating, speed was unknown, and coming to a stop sign. The next thing their son was able to recall was that the vehicle had suddenly turned right crashing into an electrical pole nearby. The air bags deployed. The driver had lost consciousness during the crash making it difficult to recall all that occurred. The vehicle was towed but they had not yet received any confirmation if the vehicle had been totaled. The electrical pole had fallen and began to catch fire. The fire department had put out the fire. The contact was not completely sure of the damage done to the vehicle. The driver lost consciousness and received an injury on their right arm. Medical attention was needed. The contact could only assume a police report had been filed but had not heard from the police department to confirm. The dealer was not contacted. The manufacturer was not made aware of the failure. The failure mileage was unknown.”

“The contact owns a 2020 Hyundai Elantra GT. The contact stated while driving 5 MPH in stop-and-go traffic, the engine light illuminated. While driving, the vehicle stalled. The vehicle was towed to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving at 35-45 MPH three days later, the engine light illuminated again, and the vehicle started to decelerate. The vehicle was towed back to the local dealer, who performed a combustion test. The dealer requested permission for a mechanic to take the vehicle to the residence for a road test. The contact declined the request. The manufacturer was contacted and opened a case. The contact requested a buyback. The failure mileage was approximately 29,000. The VIN was not available.”
