I was driving along interstate 69 near fort wayne in my leased 2006 GMC envoy denali with my boss on company business when a car from behind me pulled along side honking their horn and yelling for me to pull over and get out of my car because it was on fire. We immediately stopped, got out, and saw flames underneath the engine compartment of my vehicle. We called 911 who dispatched fort wayne fire and indiana state police personnel. The car was towed to the local GMC dealership.
My wife was involved in an accident last night in which the vehicle, a 2006 GMC envoy denali was totaled, but neither air bad deployed.
I was pulling up to park in a parking lot.I had total brake failure. The electronic safety features failed- and there was no stopping the envoy. I slid up the curb and into the building. The mechanic that repaired the envoy has a written report of the safety systems getting stuck half opened and the brake lines braking and there wasn't any fluid in system.

Last night I noticed at a stop light that I did not have low beam headlights on. Very disconcerting. After I made my turn to exit the busy street, the headlights did come back on. After researching the issue, it is a known issue with GM. In fact, many cars were selectively recalled on this issue. Mine was not. Granted, my car is 11 years old with 157,000 miles, I still believe GM at some point should have warned me of this serious and dangerous issue.
