This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Actuators stopped functioning properly to control A/C and heat in vehicle when turned on. If A/C is turned on, it may run for awhile then turn to heating cycle on one side of the vehicle or the other. This happens whether the vehicle is in motion or not. If heat is called for in winter, I.e. to defrost windows, the heat may or may not run or if running may turn to A/C. many times in winter the heat turns to A/C and there is no heat entering the vehicle. Noted there were numerous GMC vehicles with the same issue as late as 2015 when looking on the internet.
I noticed that the car was making a rattling sound. At low speeds you can hear it and sometimes when it is idling. Seems to come from the exhaust next to the gas tank.
