On [XXX] at approximately 2 pm the 2019 GMC Sierra 1500 AT4 (with 6.2 gas motor) motor died while I was driving in traffic. Incident #1 - The vehicle started sputtering and died - no alerts on dash until after the truck died - an empty fuel tank symbol briefly lit up on dash that led me to suspect a fuel pump issue as the fuel tank was full. Safety issue = vehicle failure with no warning in traffic putting occupants in risk. The vehicle would not start and was towed to the GMC dealer where I had purchased the vehicle. Incident #2, the 2019 GMC Sierra 1500 AT4 has an electronic gear shifter and will not go into neutral unless engine is running - problem as needed tow as not able to crank yet struggled to get towed as transmission will not go into neutral - apparently dealer has special tool to put 2019 GMC Sierra into neutral that is not available to consumer. Service department at dealer - Childre GMC in Milledgeville GA - contacted me on September 25, 2024 and stated 2019 GMC Sierra 1500 AT4 needs a Fuel Pump Control Module part number 13565641 but the part is not available in the GM system and may take weeks or months for part to arrive. Apparently, there are other GM trucks at this dealership waiting same part (appears to be a national issue not just a one time issue). Dealer gave me a GMC customer service number to call. I called GMC customer service on September 25, 2024 and registered a complaint that no parts are available to fix my car. Neither the selling dealer or GM customer service offered any relief with a loaner or rental car. Internet searches on forums focused on new GMC/Chevrolet trucks confirm that multiple consumers have this issue with the Fuel Pump Control Module and that GM cannot supply the repair part. The part is not available on the secondary supply chain like AutoZone, Oreilly, or similar. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
