NHTSA Complaint #11641404 — 2017 HYUNDAI TUCSON

The engine entered limp mode, lost oil pressure and began knocking. Vehicle was brought to a dealer where it remained for ~1 month. The dealer inspected the vehicle, and determined it to be a valve cover leak, which does not track given the issues. When picked up from the dealer, the engine seized shortly down the road. Upon my own inspection, it was found that the engine oil drain plug was missing. It is unclear if the dealer loosened the drain plug during their inspection, or if it fell out due to some other issue. In either case, the manufacturer and their representative (dealership) created a dangerous situation for the driver of that vehicle, which had to be pushed out of moving traffic during a busy time of day.
