I purchased this truck November 26 2016, within a month I was sitiing in my driveway I turned the truck on when I went out to go to work in the morning I got a bunch of flashing lights service stabilitrak, service 4wheel drive, service traction control, made multiple attempts to contact five star auto in biddeford, brought the truck in they refused to fix issues, asked for a trade nothing on the lot was worth purchasing without putting me out more than I already owed, christmas morning the truck was towed to weirs in arundel they pulled the truck apart and found a bunch of wires were corroded and the frame of the truck was caked with rocks mud and sand which had caused the corrosion, they fixed the issue. Within a couple months the same issue came back up and once again the truck was in the shop getting worked on. The problem is not fixed after spending money to fix a problem I had less than 30 days from buying this vehicle(driving completely normal will cause these lights to flash at random times), all the lights do still come on randomly and today while at the dayton country store my transmission in my truck went, I am waiting to get my truck towed from the store to a shop! for a vehicle that the carfax came back clean and the dealership made no attempt in helping me fix or pay for any issues I have had. Im now struggling with a vehicle that I was lied to about the condition it was in after paying $32,000 for a truck. I have kept all documentation and have images that were sent to me from weirs

The biggest problem (out of many) that makes this vehicle unsafe, stressful, and discomforting to drive is how it will randomly decides to raise the idle to 900+ RPM (in gear) and basically drives it's self. During this condition it is very difficult to operate vehicle. Because of its random pattern it caused me to have an accident that resulted in $3500 in body damage to the truck. Thank god no one was hurt. Wear and tear is drastically increased as the vehicle is trying to drive on its own as I'm trying to stop at traffic light, stop signs, or simply parking. Drive-train is banging, brakes are working harder, and fuel is being wasted. Now, add a payload or trailer as I often do and problems are magnified. Essentially the vehicle is aging and wearing its self out before its time. I have been ordered by pima county court to have the vehicle fixed or replace. The officer that gave me the citation witnessed the high engine idle and agreed that it would be difficult to stop especially with a loaded trailer as I had that day. Officer also testified this in court on 11/4/2015. There is a current law suit in California for this defect. My local dealers will not work on vehicle anymore do liability and told me take it up with GM. GM has provided no assistance.
