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.

Vehicle cranks but does not start. Security light flashing. After 10 minutes with key on and security light off after turning off then crank engine starts. Happened at least 15 times. Now, engine sometimes will crank itself in the "on" position and will not start and security light flashing. Happened three times and finally after three 10 minute key on wait cycles in a dark parking lot security light stopped flashing and started and made it home. Vehicle very unreliable now. I am tired of having a vehicle that thinks the owner is trying to steal owned vehicle. And auto crank in the on - not start- position without running. How do I bypass this awful system without another car payment to another automaker? this defect is dangerous and hazardous when stopping for fuel and have to leave engine on or holding up customers until engine starts. Also holding up vehicles on a ferry boat. Very embarrassing when friends and co workers have to wait till vehicle decides to start and run. And being late to work. I do not want new parts that will fail again, I want it bypassed. Send me a kit with directions asap!
