What owners say
The contact owns a 2025 GMC Sierra 1500. The contact stated that while driving approximately 5 - 10 MPH, the vehicle went into LIMP Mode and failed to properly accelerate, and the transmission unexpectedly downshifted. There was an electrical malfunction, which caused the transmission to downshift. An unknown message was displayed on the instrument panel. The contact stated that the network was not operating at the correct voltage due to the wiring harness. The engine light illuminated after the failure. The vehicle was towed on two occasions to the dealer to attempt to duplicate the failure. The dealer was unable to determine how to repair the vehicle. The vehicle was driven to the dealer in LIMP Mode. The manufacturer, General Motors, was contacted by the dealer, and the contact also reported the failure to the manufacturer. A General Motors service engineer had inspected the vehicle. The failure mileage was approximately 34,637.
First occurrence was 02/27/2026 - onstar detecated a critical issue, the check esc, check tsc words came on in the center dash, then the orange lights came on and my truck went into limp mode at a stop light. I had to limp mode a mile to the nearest dealer. Where nothing was repaired just reset. Second occurrence - exhaust flap valve failed creating chirping noise resulting in a muffler replacement on 04/28/2026 - picked the vehicle up on 04/30/2026 Third occurrence - 05/01/2026 came out after a wedding to start my truck which it immediately repeated the first occurrence, check esc, check tsc with the orange lights and chugging. recorded on camera now the trucks been at the dealership awaiting updates.
Driving at highway speed engine lost most power (limp mode), was able to get to an exit at low speed with flashers on but was creating a hazard on busy interstate. Dealer diagnosed truck needs new 3.0 liter duramax engine per GM TSB 25-NA-307, bad thrust bearing.
We were traveling when it went into limp mode slowing our speed way down. We got it to a dealership and they determined low oil pressure and metal in the oil. My vehicle only has 1185 miles on it.
