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.

problem #3

Blazer 4WD

  • miles
Brake lights will not work when applying brakes. Bulbs and fuses are all ok, hazard flasher when flashing causes an electrical static sound under dash and when wiggling the hazard flasher switch, brake lights will work and come on. I also own a 1996 Chevrolet Blazer that had the same problem and was repaired at bob hook Chevrolet 09/07/99 invoice no. 156312. Very little chance that I own two of the same vehicles five years apart and same defect happens to both. This is a serious safety problem that needs to be recalled before accidents occur because the vehicle behind didn't see vehicle in front stop. I am not only concerned about my family being safe but for the safety of others! why would the dealer service shop tell me that the part will have to be ordered and there is a national back order on that part but to continue to drive the vehicle? I have contacted GM. And filed a complaint # C05965366 and they said; we will do the best we can to get the part shipped. Please help get this defect recalled so potential accidents can be avoid.

During operation of vehicle, and upon applying brakes, vehicle was rear-ended by another vehicle traveling approximately 20 mph. Driver was temporarily knocked unconscious and examined by medical personnel. When dealership examined vehicle it was determined the cluster module failed, preventing brake lights from activating.
