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.

2007 Hummer H3 Owner Comments

problem #2

H3 5-cyl

  • 84,278 miles


Had purchased vehicle 3 days prior from individual. Drove to el paso TX1 approximately 80 miles drove around town doing errands. Transmission started slipping badly, I pulled into a wal-mart and went to check the transmission fluid. Vehicle had a compression type dipstick. When I touched the lever on the dipstick it shot up approximately 8 inches and showered my right hand with very hot transmission fluid. This caused second degree burns to the palm and fingers, this made a trip to the emergency room necessary. The owner of the transmission shop told me that in his 20 years in the business he had never seen a transmission get so hot as to melt the filter. This one had melted the filter.
