The rear sliding window stopped working after I tried to open it using the switch located near the rearview mirror. It had only been opened less than 12 times.

I went to open the electric rear sliding window, and it started to open, then it stopped halfway open, with a black cable hanging down. My truck only has about 23,000 miles on it, and have only open it less than 12 times. It still doesn't work. I tried to complain to General Motors Corp. Customer service, with them telling me that it would cost me $542.65 with GM assistance. This is rediculous. It must have been installed wrong, or it was defective. I was stopped at my house when this happened. I've made several calls to the customer service, speaking to several representatives, and I keep getting the same answer, thati will need to pay to have the whole window replaced (not fixed). I would like to know if there are other complaints about this same issue from other customers. The dealer that quoted me the cost was sanborn Chevrolet, in lodi, ca.

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
