2026 ZERO S

I own a 2022 Hyundai Palisade SEL. On XXX, while driving at the intersection of [XXX] and [XXX] in [XXX], the engine abruptly lost power, causing a sudden loss of engine power while the vehicle was in motion. This is my family's primary vehicle, and my wife and children were in the car during this i... ncident. On XXX, I brought the vehicle to Courtesy Hyundai in [XXX]. The dealer found essentially no oil in the engine despite my keeping up with scheduled oil changes. The dealer replaced the oil and performed a software update described on the repair order as "9C9 C ECU SW UPDATE EMISSIONS IMPRV 26-01-010H," and I was instructed to return after 1,000 miles for an oil-level recheck. At that recheck, the dealer's service assistant reported the oil was full. On XXX, before a planned family road trip, I returned the vehicle for another check. The service department found the engine was two quarts low — this was only 4,000 miles after the oil service on April 10, 2026. The dealer stated they requested an oil consumption test but that Hyundai denied the request. Per the dealer's instructions, I returned again after another 1,000 miles, and the engine was one quart low. I am filing this complaint because I believe the excessive oil consumption and the resulting loss of engine power represent a safety defect that has not been remedied. An engine that abruptly loses power while driving creates a serious hazard, including loss of power steering and reduced braking assist, and I am concerned for my family's safety while this condition remains unresolved.
