Was driving on the highway to lansing when my check engine light came on and I lost all power and guage function.I began to hear a loud howling noise, pulled off at the exit went to the repair shop in portland, mi where my wheel hub exploded in their hand on the passenger side. The fan clutch has completely stopped working witch caused the vehicle to overheat, and loose all power and my 4 wheel drive locked right up and stopped working. This was extremely dangerous at a rate of 70 mph because the vehicle slowed all the way down to 25 and had no power. I have had so many issues with this vehicle that I am now checking for recalls to have the vehicle serviced completely.

The contact owns a 2003 Chevrolet Trailblazer. The contact was driving 29 mph on an icy road and attempted to apply the brakes. There was no traction and the vehicle slid into traffic, crashing into another vehicle. The contact was not injured. The driver of the second vehicle sustained unknown injuries. A police report was filed. The vehicle was taken to the dealer where the technician diagnosed that the front passenger's side wheel hub and sensor needed to be replaced. The manufacturer was made aware of the failure. The vehicle was repaired. The failure mileage was 73,000 and the current mileage was 73,400.

Owned 03 Trailblazer for 4 months and has given me electrical & mechanical problems. I had one problem since I first bought this vehicle and now I have 13 things that are a danger to me and my family. Ac turns on by itself whether car is off or on. Ac has turned on while I was driving frightening the hell out of me causing me to almost lose control of the wheel. Ac, engine lacks horse power, hand brake, hazard lights, lights turn off, mirrors move by themselves, car boggs as if it wants to turn off, while driving steering wheel moves by itself, gas gauge has read low fuel when gas is full. I am terrified the car will give out with my child and I in it.I have tried to have vehicle repaired numerous times and still dealer can't seem to duplicate the problem. The vehicle is a hazard to me and my family and to all those who own one. Need the problem to be fixed before any tragedies occur.
