A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
We were involved in an automobile accident while driving a 2003 trailblazer xt. A driver turned in front of us at an intersection on a busy highway while we had a green light. I slammed on the brakes slowing down to what we believe to be around 35 miles per hour, and we hit head on into the side of his range rover. Neither front airbag deployed. I sustained a broken right foot and multiple bruises to my knees. I also hit the steering wheel with my chest and had many bruises to my chest.
Drivers seat will move to the "exit posistion" while driving. The last time this happened the driver was pulled away from the brake pedal while making a right hand turn and drove off the road. The vehicle has been taken to the dealership several time for repair with no luck.
Dt*: the contact stated while traveling 75 MPH the vehicle swerved to the right and then over corrected. The vehicle went into a ditch, then flipped several times however, the airbags did not deploy. Seat belts were in use and injuries were sustained. The vehicle was towed first to a wrecker service then it was taken to an insurance company. No inspection as to why the air bags did not deploy. The manufacturer has not been alerted. Updated 04/06/06.
There is a strong gasoline smell near the rear of my 2003 chevrolet trailblazer ext. No dripping gasoline is visible.
