NHTSA Complaint #11618407 — 2019 HYUNDAI VELOSTER

The contact owns a 2019 Hyundai Veloster. The contact stated that while driving 76 MPH, the vehicle went into LIMP Mode and decelerated to 30 MPH. The check engine warning light was illuminated. Additionally, the vehicle experienced intermittent, unintended acceleration. The contact shifted the transmission to neutral(N), but the vehicle failed to stop. The contact then pressed the shift lock release button, and the vehicle was able to stop. The steering wheel also inadvertently turned left or right while driving, and the Lane Keep Assist System was not activated. The vehicle was taken to the dealer, where it was diagnosed that fuel and oil were leaking into the exhaust pipe, allowing smoke into the cabin. The dealer replaced the alternator, battery, and spark plugs, but the failure persisted. The dealer notified the manufacturer about the failure. The vehicle was then taken to Tarr Hyundai (5524 W Andrew Johnson Hwy, Morristown, TN 37814); however, the dealer was initially unable to duplicate the failure. When Tarr Hyundai was able to duplicate the failure, the failure information was forwarded to the manufacturer. The vehicle was not repaired. The manufacturer was made aware of the failure and several cases were opened. The final case was resolved through arbitration, and the manufacturer was ordered to buy back the vehicle; however, the contact declined the buyback offer. The failure mileage was approximately 141.
