“Summary of Event: This vehicle was brought to an authorized Hyundai dealership for a mandatory safety recall engine replacement under the Theta II Engine Recall Campaign. The dealership successfully installed a replacement engine provided by the manufacturer. However, the dealership and Hyundai Motor America are now refusing to return the vehicle to me in a functional, safe condition. Safety Hazard & Defect: The dealership states that the replacement engine shipped by Hyundai is mechanically and physically incompatible with the vehicle's original, factory-installed high-pressure fuel pump (HPFP). In an official written correspondence from a Hyundai Motor America Corporate Case Manager, Hyundai explicitly documented that: "dealership stated that it is not safe to drive the vehicle with old fuel pump." Despite acknowledging that the vehicle is now in an "unsafe to drive" condition due to the mismatched replacement parts provided by the manufacturer, Hyundai Corporate and the dealership are refusing to complete the safety recall remedy unless I pay $1,500 out-of-pocket for a new, compatible fuel pump.”
“Odometer Fraud. The contact owns a 2014 Hyundai Sonata. The contact purchased the vehicle on April 28, 2025, with 28,974 miles from a dealer. On January 20, 2026, while attempting to start the vehicle after being parked for a while, the vehicle lost power and failed to start. The contact walked to an AutoZone nearby, where a mechanic diagnosed that the battery and starter needed to be replaced. The vehicle was repaired while with the mechanic, and the contact was informed that the actual mileage on the vehicle was 170,123. The contact reported the issue to the dealer and was informed that it would be investigated; however, the contact had not received any additional information. The dealer had taken possession of the vehicle and informed the contact that payments were still expected despite the odometer discrepancy. The manufacturer was informed of the failure and the odometer discrepancy. The failure mileage was not provided.”
“The contact owns a 2014 Hyundai Sonata. The contact stated that while driving 60 MPH, a bystander notified the contact that the brake lights were inoperable. An independent mechanic was contacted. The vehicle was taken to an independent mechanic to be diagnosed and determined that the brake light housing needed to be replaced. The brake light housing was replaced; however, the failure persisted.”
