After heavy rain the backseat of the car was flooded as well as the rear wheel well likely due to the sunroof not draining properly. This led to electrical failure of the sunroof mechanism and potential to damage other electrical elements. This will be looked at by the dealership but have read that this is a known issue.

The complaint I have is the inside front of the car is too small and I cant reach the gas pedal except with my toe. My foot keeps slipping off as I am driving. I have to have the seat way up or I cant reach. I am 5 foot tall woman. This is a ridiculous thing that I have to put up. I drove it for 10 minutes and didn't realize it. I asked for a pedal that is longer and closer to the floor after I had bought it and service people told me they don't have anything to do to fix it. They asked if I had a button to adjust it and I don't. its on the expensive one. This should be on all vehicles for safety. I wanted to give it back but they never helped me. I have 1100 miles on it.it new still. The other thing this creates is I am up so close to the steering wheel that its almost on my chest in order to reach pedal without having to strain and later having pain in my leg from doing that. I am so disappointed with chuck nash GMC in san marcos, Texas. Is there anything to be done by the GMC company. I also told the salesman I wanted a canyon pickup like I had before. I traded that one in due to the fact that the 2017 canyon was always in the shop. Only had it for 2 yrs and 1 month. They were no help! thank you, [xxx] please help me information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
