“The 2019 GMC Sierra AT4 with the 6.2L V8 engine began making a rattling or tapping noise at 45 mph. No warning lights appeared on the dashboard. When starting the engine and idling, a similar noise can be heard from the engine. I bought the vehicle used from a dealership one month ago, with 80,000 miles, and the second issue is the complete failure of the blind spot warning system on both mirrors. It was a one-owner vehicle with a clean Carfax. I am scheduled to take the vehicle to the dealership's service department for a full inspection.”
NHTSA complaint #11723178, filed 2026-03“Rear window leaks as also reported by GM when truck was manufactured (GM Service Bulletin 18-NA-383). Water from leaking rear window gets into the electronics used for safety systems as well as rear camera and eventually disables safety systems.”
