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.

A warning light stating "service 4WD now" appeared on my dash of my 2003. Chevrolet Avalanche. According to the owner's manaul, this indicates that there is a problem with the 4-wheel drive of my vehicle. Upon inspection at the local Chevrolet dealership, I was informed that there is a bulletin from GM stating not to do any repairs for this concern. My vehicle is now stuck in 2wd and GM does not know if or when they will be able to remedy this defect.
