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.

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).

Left driver's side outside mirror is not holding the correct settings, and clicks constantly. The mirror is hitting against something, and turns completely to the ground. When using keyless entry the mirrors also turn to the ground. The mirror is changing by itself, and it is not going back to the correct setting. The mirror is always making a clicking noise and it is facing downward. There is no problem with the right side. The dealer replaced the right side mirror, and from then on the left side has not worked. Consumer has taken vehicle to dealership 4 or 5 times to be checked. Dealership insists the mirror is working fine. But as soon as the consumer leaves the dealership the mirror will work for a couple of hours and then stop working properly. Consumer took the vehicle to the dealership and the mechanic didn't write down the problem with the mirror in his paperwork, and this happened more than once. When shifting from park to reverse the vehicle jerked at times. The engine control module was reprogrammed. The consumer believes that the reprogramming resulted in poor fuel economy. The cd player made a hissing noise. When the brakes were applied they would grind. The 4-wheel drive switch shorted. Windshield wiper motor failed. Right side tag light bulb blew.
