Consumer Description
Vehicle (2019 GMC Sierra SLT X31!Crew Cab 6.2 l gas engine) stopped running while driving down the road (Wednesday [XXX]. Tried to start truck - would crank over quickly but failed to start ( crank no start with no check engine light.) tried several times same result. Started after about 5-10 minutes and was displaying low fuel indicator even though we knew it had approximately 1/2 tank. We immediately put gas in it and it took approximately 1/2 tank to fill. Still no check engine light and confirmed no stored codes via onstar report. Drove the truck around for may 1hr and check engine light came on but was still running and did not stop running like it did earlier. On star reported ECM SYSTEM CODE P129F ( Fuel pump or fuel pump power control module). Long story short, put truck in independent repair shop I use. They diagnosed it was a defective fuel pump located in fuel tank. They told me GM technical support recommended to replace the fuel pump and fuel pump power and control module at a cost of ~$1325.00. It is my opinion this is a safety hazard and very similar if not exactly the same failure symptoms / modes as others have already reported. I requested to keep the failed parts and still have them in my possession. Please review and let me know if you need or want additional information . Best Regards, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
