Example complaints
Brakes: “The electronic part of the truck gave a warning and shut off my trailer brake system while towing a 21K 5th wheel trailer (X2). The truck is available for inspection. Any part of the electronics package that has the ability to disable a trailer braking system while towing needs to be removed/disabled immediately. The truck has not been seen by a dealer yet. yes there was a warning I briefly saw both times, but I can't say what it said.”
NHTSA complaint #11732209, filed 2026-04Electrical system: “weekly you will start the truck and have no audio of any kind. No blinker noises no collision warning noises, no radio, no on star noise. No sound at all and sound will never come back on until you turn truck off and wait 20 mins. GMC says it's a known software issue, but this has been going on since I bought the truck brand new back is April of 2025. I live in a hands free while driving state when it's come to cell phone use and can't even take a call with no audio of any kind. I don't see how GMC can say this isn't a safety issue.”
NHTSA complaint #11699761, filed 2025-11Engine: ““I own a 2025 GMC Sierra with 30,000 miles. The oil cooler failed and caused loss of oil pressure and potential internal engine damage. The dealership acknowledges the failure but refuses to escalate the case or perform a proper inspection. I am being instructed to continue driving the truck even though it may suffer catastrophic failure while driving. This is a safety hazard.””
