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.
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.
