One problem related to tire blowout has been reported for the 2005 GMC Envoy. The most recently reported issues are listed below.
I own a 2005 Envoy sle. I was involved in an accident that was a result of a tire blowout. I was changing lanes on a city street. I moved from the right lane to the left lane. The vehicle did not want to adjust to moving over. I than excellerated the vehicle and it began to fish tail. I tried to correct the vehicle from swirving and I hit the guard rail. When I got out of the vehicle the rear tire on the passenger side was flat. I did not hit the guard rail with the rear of the car only the front. I believe the blowout was the reason the car was out of control. I am saving the tire to have someone inspect it just to see if my claims could be right. The dealership did not find any cuts in the tire to represent I ran over something prior to the accident. Please contact me at 517/636-6528 my name is rose heyer I am peter deluca's daugher who was driving the vehicle.
