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: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

Have had many of the problems I read on posted complaints: New engine required within nine months-one year of owning new vehicle, inside driver door panel replaced three times, change oil and service engine lights staying on, hood not closing properly, back glass needing replacement, fabric problems in back seat, etc., etc. And this morning it is a $200 problem with the headlight switch. Too many things to even remember or name, but Chevy has a pretty thick file on me and my vehicle.

Trailblazer 4WD

Consumer stated that without warning the hatchback exploded. Dealer notified. Vehicle was parked in the driveway. Consumer believed it was a design flaw. The arms to open the window forced the glass outward up to 10 feet. If the glass goes, the arms are forced to open like two catapults. Dealer refused to acknowledge the problem and correct it under warranty.
