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.

I bought my car used and it has a new tranny, cv axles and everything the only thing original is the engine. So I have already had to replace the O2 sensors twice at $60 each. I have had to replace the tps sensor, thermostat and housing, ignition coil, battery, starter, fuel pump and alternator. All because I kept getting the check engine lights on and throwing coding all over the place. And the car still stalls when I stop at a stop light and runs and idles rough. I have spent over $1500 fix this problem and it still exists I did all the work myself I have worked on cars my whole life and am a mechinic. Every mechanic I take it to can bot find the problem and Suzuki can't give an answer to the problem and I don't know what to do.
