“Sirius xm signal is not working and I have had the dealer do a reboot/reset on the radio. The reset worked for 2-3 months when I took it to gilchrist Chevrolet in tacoma wa. I have lost signal again and dealership is not very helpful with this type of situation. Sirius xm points their finger at GM and GM is pointing their finger at sirius xm. I just want my radio to work. Dealership does not seem knowledgeable about hybrid cars that GM manufactured.”

“Rear door locks (actuators) stopped working. First passenger rear lock failed to open or close. This happened after warranty coverage had ended. After some research I have found out that this is a widespread GM issue especially with 2008-09 GM SUV type of vehicles. My understanding is that the actuator motor fails. It is also my understanding that this electrical failure is due to a very inexpensive electrical actuator is used for the locking mechanism. This is a real safety issue and I am wondering when GM will be held accountable.”
