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.

Print this page 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.

I have a 2003 Chevrolet Trailblazer lt model. The rear hatch latch fails to lock or unlock due to corrosion. I found online that there is a recall covering certain GMC vehicles. The site I found listed the 2003 Chevrolet vehicle as part of this recall. The campaign # is 05V494000 and the GM recall # is 05V494000. The recall stated the following:certain sport utility vehicles have a rear side closure latch that may not latch or unlatch due to corrosion caused by road splash, such as water and road salt. These vehicles were originally sold in or currently registered in the following states: Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. Consequence summary: If the door is not latched properly and it goes unnoticed, it may open while the vehicle is in motion. If an unbelted occupant fell out of the vehicle, personal injuries could occur. Recall notes: GM recall no. 05077. I contacted Chevrolet 1-800-630-2438. I spoke with a representative there and gave him all my information. He informed me that he could not find any recalls on my vehicle. I gave him the campaign # listed on the website and he looked it up and found the recall and said that Maine was not a state involved in the recall. I informed him that the recall I was viewing on line clearly listed Maine as a covered state. He then said he noticed it. I gave him the GM recall # and he said that the recall only covers GMC Envoy and Chevrolet Trailblazer ext models. It clearly is the same problem. I checked and the latch is corroded due to salt and water. My complaint is that this is the same safety issue as the other vehicles and should be covered on this recall. The only difference is the trim its lt as opposed to the ext.

Raised rear lightgate heard a crunching sound. On inspection the plastic piece on the top of the lightgate was cracked & lifted up. It was a fairly warm day & I had washed the truck early in the day & it sat in the sun all day. Ice build up was not a possibility. Took the truck in for repair of this piece, bodyshop states that there are 2 bushings missing from the hinges where the rear glass pivots on the hinges. Dealer parts dept. Confirms that bushings should be there. Parts dept. Had conversation with GM customer service these hinges & replacement bushing are only services able when the rear liftgate glass gets replaced.

When using the remote control to lock or unlock the vehicle the mirrors moved and it changed the position of the mirrors. Consumer drove the vehicle and noticed the mirrors were facing the ground or the sky. Vehicle were taken to the dealer, and nothing was done to correct the problem.
