Twice had to have wiring repaired because animals ate the wiring. Both were caused by GM using soy based insulation on wiring that made it a delicacy to the animals and caused them to eat through two wiring harnesses, one of which GM no longer makes. The other complaint is the timing belt has stretched and is now in need of replacement at a cost of $4500 to $5000.

The defroster/ radio control/ heating area stopped working. Upon visiting a mechanic was told they never seen this or heard of this happening before and quoted me over $1,000.00 dollars to fix stating that due to Federal Law they have to give an estimate but this problem not being in their system they came up with an estimate based on parts and labor. Upon searching online I found a recall for this issue dating back to 2009 recall number was 09V489000 but was never informed about this and while looking up my car it’s not listed but being a safety issue should still be current which it is not.

Driving 50 MPH on the highway, my car decided to 'reduce engine power' and 'service stabilitrak' came on, immediately making the car slow dance forcibly to 25 MPH. The car was shaking and stepping on the gas did nothing. That's dangerous, because the person behind me has to swerve or hit into the back of me for sudden drop in speed. You guys should know better! Happened twice in one day. I had to restart the car, and it happened going onto the bridge. Someone could be seriously hurt, or killed. Do better!
