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: 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.

Trailblazer 4WD

This SUV automatically locks into 4-wheel drive while you are driving the vehicle. I have had the SUV in the service garage 3 times. Nov. 13, Dec 19, and Dec. 27. all three times they replaced the transfer case switch. The SUV is still locking into 4-wheel hi while driving. Jan.2 I almost wrecked because it engaged at 35-40 miles per hour while going around a bend. The vehicle had to be shut off to disengage the 4-wheel drive system. I have contacted GM about this problem and they are basically ignoring it. Please help find out what the problem is before someone is hurt.
