2017 GMC Acadia: fuel pump failure

Filed Jun 18, 2026 · Electrical, Fuel system · KS

Vehicle has experienced multiple electrical and mechanical failures at unusually low mileage. Purchased at 32,000 miles. At approximately 50,000 miles, the factory radio/infotainment system failed completely. Electrical systems were observed remaining active after the vehicle was powered off, suggesting an underlying electrical fault. At approximately 60,000 miles, the power steering rack and fuel pump both required full replacement and were confirmed and replaced by an authorized dealership. No warning lights appeared prior to these failures — components failed without any prior indication. At approximately 100,000 miles, the transmission began failing and exhibits the known torque converter shudder issue widely reported on this vehicle platform. The shudder was present prior to full transmission failure symptoms appearing. The pattern of premature failures across multiple unrelated systems — electrical, steering, fuel delivery, and transmission — suggests a broader manufacturing defect.

While highway driving, engine suddenly lost power and car could not exceed 5 mph. Was able to get off at next exit and get to a local garage. Mechanic inspected. Bolt connecting high pressure fuel pump to cylinder sheared off leaving bolt body in cylinder, bending fuel pump and caused oil to spray over entire engine compartment. Repair unlikely. Engine will likely need to be replaced. Car has always been maintained. No indication of failure prior to incident.

Starting vehicle after 10 hours of vehicle not running, the vehicle cranks/has a delayed start for approximately 4 to 8 seconds. Battery, alternator and start was check and all was in working order. I was told the issue may be a defective fuel pump, due to the engine losing fuel pressure after not running for an extended period of time.

The vehicle has had ongoing issues since it was purchased in june of 2017. The 'shift to park' problem had to be fixed twice, the emergency braking system engages itself for no apparent reason which has almost caused several accidents, the horn does not work when needed in emergency situations, the headlights are so dim it's dangerous, the battery has drained and left my wife stranded 4 times, and the vehicle has a very rough idle and it almost stalls out. I attempted to work with gm to have them take the car back early (lease) and the request was recently denied. This is my 3rd acadia and it by far is the most dangerous car I have ever driven. I am now reading about a fuel pump problem that could cause the vehicle to catch on fire, a driveshaft that may separate while driving, and a faulty braking system that could cause the vehicle to lose all braking capability. I do not feel safe having my family in this car and I am requesting your assistance to help me work with gm on a resolution. I entered the date that the vehicle first started to have issues, there have been over 20 incidents over a 2.5 year period causing a safety issue or leaving my wife and children stranded.

Oct 23, 2019 we were supposed to bring our car for a service because the check engine is on but before we even get to the dealer the car won't start. We have to call for a towing company. When we get there they said they don't know what's wrong. We called gmc complaint before we got an answer with the dealer on oct 30 they said its a fuel pump recall. Since then we haven't heard from them. It will 6 weeks this week. We just bought this car as certified pre owned last april 2019 now we cant't use it and no updates at all. We don't know when will have our car back.
