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.

Suburban 4WD 8-cyl

  • Automatic transmission

Noticed a strong smell of antifreeze from outside the vehicle after turning it off. Then began to notice fluid leaking from under right rear quarter behind the wheel. Took vehicle to webb Chevrolet. Diagnosis was faulty coolant lines running into other lines forcing a leak of coolant. I wasn't to clear on diagnosis, but they had to order parts and we lost the vehicle for 3 days.
