2008 with 153k miles and bone stock. Nothing but the tpms warning when I bought it. Driving it home, check engine light came on. That evening, I started to reset the tpms system but didn't realize I would needto inflate ordeflate the tires. It was late andi went to bed. Next morning, no tpms, no check engine. The scanner says it was a 303 and 0014 code. I plan on replacing coil packs and spark plugs with my normal oil change tune up. But I've noticed how many interior lights aren't working. Two of the hvac knows, nothing on the door controls... but I will get those done.
The Big thing is the stock stereo. Only the right tweeter works. :-(
It's GM, what did I suspect...
