NHTSA Complaint #11679168 — 2021 GMC ACADIA

Car was parked overnight in my garage and in the morning it would turn over, but not start. Had to have it towed to my GMC dealer, but had great difficulty moving the car out of the garage because the transmission remains in PARK if the engine is not running. Had this happened on a highway while driving and without a place to safely get off the road ( which HAS happened to others who have made this same complaint to NHTSA), this could have been an extremely hazardous situation for the occupants of the vehicle. The engine will suddenly shut down, power steering is lost, and power braking will also be lost. This problem was diagnosed as a failed fuel pump module. The failed part was replaced by the dealer (GM part#13554820). The service manager acknowledged that this is a known and common issue and that GM is aware of it but has not issued a voluntary recall. The manager also advised that this part has not been updated and that it may fail again without warning. Please....this is a serious safety issue that needs to be addressed before someone is injured or killed while abandoning a car stalled in traffic that cannot be moved.
