'Service Stabilitrak' refuses to be fixed.
I bought this truck three months ago with 32000 miles. On the way home, the Stabilitrak light comes on. I figured since there was a crap ton of snow, it must've been that. I called the dealer who sold it to me and they confirmed that. I also scheduled an appointment to have it fixed at my local dealer. They replaced my electronic brake control module and kept it for a couple days. Later that week, it pops back on again. I take it in again, they have no idea what to do other than put so dielectric grease on some electrical ends, thinking it's a short. It comes on whenever I start the truck the truck, or whenever I'm just about the park it. I do not hammer this truck, it's the nicest vehicle I've ever had so I want to last.
Fastforward two months and 3000 miles, it's back on again, so it's back at the dealer.. Onstar told me it's throwing a u0077 code. Can't find much information on it other than Stabilitrak and anti lock brake related. The warranty is still active til 48000 miles, but I can't keep dropping my truck off. I'm a full time nursing student with a full time job, I need this vehicle. Any idea what to do or where to point the techs to if they can't figure it out this time? I'm about to call up GM and throw a fit and get them to give me a huge discount on an extended warranty cause I'm nervous these problems will keep coming up..
