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.

1998 GMC Jimmy Owner Comments

I have a 1998 GMC Jimmy - 4 wheel drive and am experiencing this problem with my SUV at this moment. There is an orange mud-like substance came from underneath my vehicle. The engine light never came on to indicate that there was a problem with my vehicle. I took it to a nearby shop and they stated that it may be an engine problem. They stated that we may need to replace the water pump and thermostats and possible damage to the engine. I am concerned that this has destroyed my engine.

Thank you for your time.
