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.

Main computer failed while driving causing total loss of power. One pin was bad in the computer that controls the cars fuel, engine, etc. Replaced the defective computer costing over $1,000. Prior to the failure the check engine light came on many times. The computer did not store a code for this problem. This total loss of power is a costly safety issue.
