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.

1) on interstate I-495 long island expwy, car moving slow came from on ramp straight across to middle lane. Went to accelerate to pass in left lane and engine stopped. Putted on emergency flashers and was able to pull into hov shoulder and restart engine. 2) on northern state pkwy (2 lanes only) on long island, NY and was in right lane- saw oncoming traffic merging ahead and went to give gas to move over to left lane and engine stopped. Again- moved to shoulder, restarted engine. 3) was doing 65 on njtpke I-95N in left lane between cars and trucks on right. Engine stopped (no acceleration- just straight driving). I was between vehicles and no place to pull over- put car into N and restarted and back to drive. This happened again- did same thing. When it was clear- pulled over to right shoulder- turned car off and restarted and continued trip. ** could this be part of the recent recall on caddys 2005-11 but did not include Sts's"??" just for the record- have new air filter and sprayed both the maf and throttle body valve with correct cleaners- recently- after seeing a video on caddy complaint forum.

Car lurched to left into oncoming lane, braking as it veered left. Had I been driving 70 on freeway, I believe there would have been a major accident.
