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.

CarComplaints.com Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

The contact owns a 2003 Chevrolet Trailblazer. For quite some time, the contact has been hearing a noise coming from the rear of the vehicle. He finally took the vehicle to the dealer and they stated that the rear suspension sway bar was loose because the weight of the vehicle was too heavy for the bar. The manufacturer took a report and declined to assist with the repair. The contact paid $307 to have the vehicle repaired. The failure and current mileages were 32,000.

Water has been seen several times dripping from underneath the truck in the center area. It appears to be from the emissions system. No wet weather at the time. It appears to be some sort of condensation. Also fan clutch failure, sway bar linkages failure, tie-rod failure, rack and pinion failure/leak, control arm failures 2 times, windshield wiper would not turn off failure, windshield wiper reservoir tank leak replaced, ac cold air failure. All needed to be replaced on a vehicle less than 5 years old with only 38,000 miles on it.

They replaced the stabilizer links 5 times. The problem recurred. Took the vehicle to another dealership, and they also replaced the stabilizer links. The vehicle shook, and shimmied.
