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.

It would switch from 2 wheel drive to 4 wheel drive while driving, causing car to slow down dramatically. Transfer case actuator module bad on truck when called for warranty they stated it was a common failure. I felt it was a deadly and dangerous situation, depending on where you were driving when it happens, and should be looked into.

Transfer case has failed 3 times, and each time it was replaced by the dealer. It stayed in 4 high, and it just locked up, consumer had it replaced and it worked for a minute and failed again, it kept doing the same thing.

The four wheel drive did not engage properly. The switch was disconnected by the dealer and the part would be replaced, once it arrived.

  • Automatic transmission

Our 2001 Blazer 4WD failed to engage. We were traveling East on highway 36. It was snowing. I pressed the 4WD hi button and it continued to blink. We were on a narrow two lane highway and had no where to pull over. The 4 wheel drive failed to engage and the Blazer, within seconds sliped over the cliff. The front wheels did not lock in. We rolled down the cliff approximately 50 feet and hit a tree.

When the car in gear on a hill, it will roll down the hill and increase in speed. The car rolls so fast that you cannot safely make the transition from brake to accelerator without rolling severely, the manufacturer stated that this falls within specs, the 4 wheel drive service light is illuminated.
