Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

On November 26 2007 took my Chevy trailblazer 04 4 wheel dr. In for steering wheel shimmy. Could not duplicate. Also C.D. changer will not eject cd's and low beams on headlights not working. Repaired headlights and C.D. changer. Did not fix steering problem. On June 07 took in for major service with 33,000 miles. On Dec.8 2008 took in for stalling when coming to a stop. Could not duplicate the problem.this is my main complaint, the stalling on Jan.. 10 2009 took in for erratic speedometer which was happening for about 3 months off and on.rebuilt the speedometer. On June 11 2009 took car in for stalling, ses lamp comes on when driving and HVAC fan does not blow on the #5 position. There is alot of grinding and whining when vehicle shifts to second gear. And turning at low speeds there is a whining coming from the front end. Removed and replaced 02 sensor. For the stalling they could not verify concern. Recommended throttle body de-carb and injection system cleaning. For the #5 fan not working removed and replaced speed control resistor. Transmission they could not feel any unusual shifting.for the steering prob.replaced power steering pump and power steering gear. Car still stalling on 6-19 -09. Took in. Did another decarb service and replace fuel filter.still stalls. 7-01-09 when car starts there is a loud clutch fan noise like a jet taking off. Feels like the trans is overworking, veryloud not right. Fix, was fancontrol set im properly trouble code P0483. Bulletin 05-06-02-004 reprogram PCM. Claim code1013B. July 8 took car for stalling issue July 9 took car for stalling issue July 10 took car for stalling issues no paper work for these 3 days they were trying to recreate the stalling issue. July 20 2009 in shop for 16 days for stalling issue they finally confirmed.replaced PCM. They called in tech assistance case #10971267 he said to perform top engine cleaning. Outcome is cannot guarantee repairs at this time due to how random this prob occurs.

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission

I am in the process of having to replace the head unit for my stereo due to malfunctions, my driver side view mirror due to constant shaking, a seal in the window that was coming out, driver side door panel due to the plastic bowing up. Occasionally the rear windshield wiper does not work, as well as the driver's seatbelt fails to release allowing me to put my seatbelt on. Excess wind noise on the driverside possibly due to the windshield not being sealed properly.
