NHTSA Complaint #11718913 — 2025 HYUNDAI PALISADE

I am reporting a serious safety issue involving my 2025 Hyundai Palisade. The vehicle has repeatedly produced white smoke during cold start and has experienced loss of engine power while driving. Despite multiple repair visits (six times) to an authorized Hyundai dealership, the dealer repeatedly stated that the condition could not be reproduced and no repairs were performed. I provided video evidence of the white smoke and described the symptoms in writing at each visit. Shortly after the most recent service visit(12/22/25), within approximately five days, the vehicle displayed an “Engine Power Limited” warning message and a malfunction indicator light (MIL). When this occurred, the vehicle’s power was significantly reduced, making it difficult to maintain speed and creating a potentially dangerous condition, especially during highway driving or merging into traffic. This issue poses a serious safety risk because sudden loss of engine power can increase the risk of collision. The problem appears to be intermittent but recurring, and it has not been properly diagnosed or corrected by the dealership despite repeated opportunities. The vehicle has not been repaired for this condition, and the defect remains unresolved. The condition may be available for inspection upon request, and diagnostic data such as warning messages and onboard fault codes should be present in the vehicle’s system. The failure began with white smoke during cold start and later escalated to engine power limitation and warning lights.
