* Recall Campaign Number : [018G, 019G] I. Statement of Complaint This complaint concerns a failure in a critical safety-related component that was previously addressed under a mandatory manufacturer recall, and the subsequent refusal by the authorized dealership to provide a second no-charge repair for the same repeated failure. II. Chronology of Events * Original Recall Repair: Approximately thirteen (13) months ago, 8/30/2024 the vehicle was taken to Anaheim Hyundai to address a safety recall concerning the...

oil feed pipe. The prescribed remedy, a replacement of the oil feed pipe, was completed at no cost under the recall campaign. * Second Failure (Current Event): On or about 10/6/2025, while the vehicle's engine was running, I observed smoke rising from the engine compartment. The vehicle was immediately taken to a local independent mechanic who diagnosed the issue as a burst oil feed pipe - the identical component subject to the prior recall. * Attempted Repair at Anaheim Hyundai (Denial): The vehicle was then towed back to Anaheim Hyundai. The service department acknowledged that the component failure was the same issue addressed in the previous recall. However, the dealership has now refused to perform the repair under the recall process, citing a specific 12-month policy set by Hyundai Motor America regarding the warranty on recall remedies, which has now expired. III. Request for Intervention The failure of the previously installed recall remedy (the oil feed pipe) exposes the vehicle to the original safety risk, including potential engine failure and fire hazards, and the manufacturer's refusal to re-remedy the defect effectively negates the purpose of the mandatory recall. I request that NHTSA investigate this matter and compel Hyundai Motor America to: * Honor the original safety recall and provide a permanent, effective remedy at no charge to the consumer. * Clarify the consumer's right regarding the warranty on recall remedies, fails after install
