What 2001 Chevrolet Trailblazer owners say
Engine & cooling
While driving ABS light came on. When applying brakes pedal went to the floor. Dealer contacted. The vehicle had gone through five red lights, intersections, and stop signs with no brakes and was unable to stop. Other problems were: the tires were out of round(all 4), there were no brake or tail lights, the engine surged, the speedometer fluctuated, there was a smoke and or smoky odor, the electronic brake control failed, the vehicle did not start, the brakes would lock when the vehicle was backed, and the battery died.
Consumer stated that while driving and without warning oil is leaking from the vehicle and causing the consumer to refill more then often. Cause unknown. Dealer notified. Ts
Transmission & drivetrain
My 2001 Chevy tb has already had the transmission rebuilt as the result of a sun shield failure at 36K miles. As of right now I am at 90K and it is failing again. A quick search through edmunds.com shows this is not an isolated incident. Chevy has done nothing to rectify this and since they were the ones who supposedly fixed it before, they have obviously not attempted to engineer an adequate fix for this failure. If this fails on an interstate there will be a serious safety issue for me and my family.
While pulling out onto a busy highwaytransmission jerked and bogged down. When trying to accelerate to keep from getting rear ended, I pushed the acceleratot but 1st to second gear would not engage. After backing of the accelerator the gears caught. Now it will not go in reverse and 1st to 2nd and 3rd to 4th has trouble engaging.
Brakes
While coming to a stop in my 2001 Chevy Trailblazer the brake system (ABS) keeps engaging causing it not to stop. I have went through many stop signs and intersections from not being able to stop. Changed all the brakes ,bleed the brakes and put new sensors on..still having the same issues . I have read that GM knows that this is a flaw in the design ,what can be done about it?
