2007: “My 2007 gms denali envoy lowers itself independently when not be driven for about 6 hours or more. The vehicle was taken to the dealership and told that there is a leak in the rear bags. The vehicle was not repaired. I took the vehicle to an independent mechanic for a second opinion. His findings were the same and cheaper in the price to repair.”

I must speed home or to a safe area to let the engine cool. If I come back in a few hours,the truck will start with no problem. It has been to the shop more often then I remember. Is there anyone having these same issues?”
