In October of 2020, my avalanche only would start in winter after disconnecting and reconnecting the battery. It was also on numerous occasions go into limp mode while driving at normal city speeds meaning it wouldn’t go above 25 miles an hour. The entire dash would light up. It threw numerous codes. Had to be towed to get it looked at but then would mysteriously start without issue. I took it to young Buick gmc in Layton Utah with no resolution. Finally in December 2020 it was determined by now Heritage Chevrolet in Evanston Wyoming to be the Onstar module. This part was no longer available and couldn’t be replaced. The dealership’s solution was to wire around the faulty part which has allowed the truck to start and no longer go into limp mode from 70mph on highway to 20mph without notice. I immediately got a hold of Chevrolet to get a satisfactory answer about why I couldn’t get the part that was making the vehicle unsafe to drive. They said the part was no longer being manufactured and it wasn’t their problem sorry about the inconvenience Case number [XXX]. I did have the dealership wire around it so I have the truck working, but Chevrolet did not care about the truck going into limp mode suddenly on the highway and it could have caused an accident. They not not offer any compensation for the part not being manufactured and according to to your website if a part is causing a safety issue they are they are required to have that part fixed. I am still upset about their lack of support and service and want Chevrolet held accountable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Having alot of issues with the drain tubes especially with the front top tubes my floor boards are being soaked. The tubes are plastic so when and why for the drain tubes and how often should they be really be changed. The seal above driver door and passenger door in front are not always put in correctly or they move causing the water to cross over and pull into car instead of exiting. And the ac plug also problem. Certain years do not have the cabin filters .The engine light is very sensitive as well.
