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.

While driving at 65 miles per hour the vehicle dash lit up all service lights the vehicle went into reduced power mode not allowing the vehicle to exceed 40 mph and ABS sensors came on staying traction fail, ABS fail, began to stutter and stall. Took to shop. Vehicle running codes for spark plugs, replaced spark plugs. Few weeks later did it again, this time saying throttle body. Replaced it, a month later did it again, each time in major traffic having to pull off roadway to avoid an accident. This time says misfiring, throttle body, ABS, TPMS, thermostat, etc. Take it to have compression test run and system says cylinder failure. Do research on issue and find that there are hundreds of complaints about this online having caused accidents and thousand of dollars spent by consumers after having accidents but no known fatality so GM will no recall or honor the issue repairs. Almost all of them happening at 100K miles.

Started out right rear blinker. Grew to both rear blinkers. Then to all systems worked while brakes applied, then to rear blinker fuse blows when brakes applied. The bulbs were changed but not damaged, diagnosis is body control module. This is a recurring problem with this SUV and is a serious safety hazard to have brake light failure and blinker failure. Should be recalled.
