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.

Drivers side front window falls down without warning, into the door. Will not roll up into the fully closed position when electric window switch is activated. Must manually push the glass into the fully closed position, however, as stated above, it will fall without warning. This creates a serious hazard in that when the window falls without warning, not only can the driver be startled and make a driving error, but also, given the exterior conditions, create a very unsafe driving / operational environment which could result in a crash.

The rear left passenger window began to grind when letting it up and down then it quit working. The right front passenger began to do the same thing soon after. The windows currently have a suction cup holding them up.

Multiple problems with this vehicle with only 40,000 miles on it! power window assembly broke and repaired twice on the same door, inoperable climate control unit, front dashboard gets extremely hot at all times, brakes squeal all the time (dealer could not figure it out and was remedied with ceramic brake pads after multiple attempts), transmission has poor shifting pattern (bulletin provided a new shift program for the transmission and the dealer installed but is right back to it's original problem after 3 months).

  • Automatic transmission

You start to hear a noise when the window is being put up or down, then eventually the mechanics of the window break and the window falls into the socket and will not go up or down. Two of my windows needed to be repaired, costing me several hundreds of dollars later. Same situation in two of my friends cars. Same make and model.
