My trailblazer has stalled (cut off) now 4 times and it is getting old and unsafe. When you are going down I-95 and it cuts off. Imagine having no powering steering and trying to get out of the way before you get hit going 70 mph! and Chevrolet will not take it back or help with a trade! I may contact the papers and have someone look into this!!

Engine stalls at various times for no reason. Have had it into dealership many times. Dealership has been unable to isolate problem. Service engine soon light came on after first stall. Dealership reset computer. Since then, the engine has stalled at least 5 times. Ses light has not come back on. Engine usually restarts after approx 5 minutes.

Trailblazer EXT 6-cyl

Full destruction because of fire I was on the way back from a long trip in southern chile (up to ushuaia) over the "carretera austral" and, after about 9'000 km drive without any problem, I saw a white smoke back my vehicle. Oil pressure: Normal, motor temperature: Normal. This meant immediate stop along the "ruta 40 norte" in argentina (about 100 km North of bariloche, on the way to neuqu). While stopping, I felt the brake pedal just going without immediate reaction but the pression came back. While bringing the gear shift to position parking, I did not feel any sensation, as if it would have no connection; the automatic door blocker connected to the gear shift did not work too, so that we had to unlock the doors manually. After having disconnected the engine, I saw white smoke coming out from the upper left corner of the motor. I opened the capot and the smoke came from the left corner (close to the driver's place). Suddenly, some material in flames fell to the bottom, about middle light left of the car. I tried to put out the flames with the extinguisher, but other burning material fell. Other people had stopped and helped me. We pushed the car a little ahead - though the hand brake was tied and the gear shift on "P", but burning material fell again. In the meantime, my wife and children throw out the luggage, so that we could save almost all of it. But the car burned entirely. What could be the reason of this incident ? thanks god, I stopped immediately so that nobody was injured nor burned and no third party suffered any damage.
