GM filed this with NHTSA as a service campaign dated Aug 4, 2026, about the engine. It names 6 model years across Chevrolet, GMC and Cadillac (2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 321 complaints with NHTSA since 2015. 179 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The vehicle developed a rapid and moderate shudder followed by "Check Engine", "Service Traction Control", "Service ESC" messages and associated icons on the driver display. The shudder happened a second time within approximately 30 seconds and the engine lost power followed by "Reduced Power Warning" message.
