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.

Locks began locking occasionally while driving at speeds about 20mph. I would be driving at 70mph and they would re lock. One day they relocked at least 14 times in one drive time. I began to notice every time I would accelerate from a stopped position(while still in drive), they would lock around 23mph. Then the whole car shut down while in drive. I figured the locking was a precursor to the shut down, but the dealership I had the vehicle towed to said there was no apparent reason for any problem. They claim to had driven the car while trying to diagnose the problems and it drove great with no locking or shutting down. I have seen others have had these same problems in online car forums with no diagnosis to speak of.

For the past few months if I get out of my car and lock it it has been beeping, letting me know that it is locked, but has not been actually locking. At first I thought it was a problem with the remote and tried locking the doors with the switch on the door. Usually it would lock if I tried with the switch but today it did not and going around to all the doors and pushing down the lock is ANNOYING! It has gradually been getting worse which leads me to think it is a short in a wire and I also have no bad fuses and I don't think there is a relay for the doors.
