Example complaints
Engine: “My check engine light came on along with my traction control light, and Reduced Engine Power popped up. This is connected to a recall on this vehicle for a connector at the throttle pedal.”
NHTSA complaint #11632118, filed 2024-12Other or unknown: “When auto start/stop turns on the aux pump that pumps coolant into the cabin to continue to heat makes the most annoying sound in the world. Gm states that it's normal but, under normal operation you can barely hear the pump. When it malfunctions you can hear it down the block. But sure, that's normal, of course it is. That's why they changed the design of the aux pump for 2020 but won't admit fault. Gm refusing to change the aux pump, I had to buy it and do the work myself. Buick warranty is useless.”
