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.

Was driving with 50 mph and traffic stopped so I had to press the brakes a little harder. At that point both rear leaf springs failed, damaging drive shaft and pulling driveshaft from the transfer case. Repairs for all this were $2700.......updated 09-03-14 updated 09/8/2014

The contact owns a 2006 Hummer H3. While the vehicle was parked the contact noticed the HVAC unit failed. The vehicle was taken to the dealer for diagnostic testing and the technicians stated the HVAC blower motor over heated and melted the resistor. The technicians stated the blower motor, relay and the wiring harness needed to be replaced. The vehicle was not repaired. While driving the front drivers side mirror also began to vibrate and when depressing the accelerator pedal the vehicle would decelerate. The technician stated that the arm bracket that holds the front drivers side door mirror was broken and needed to be replaced. The vehicle was taken to the dealer where the electric pedal was replaced. The vehicle HVAC unit and the drivers side mirror were not repaired. The approximate failure mileage was 90,000.

So could you please investigate on this, because it happen to me it could happen to other Hummer H3 owner.

The gas pedal is too close to the brake pedal, causing your shoe to get stuck when switching from gas to brake.
