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 was northbound on interstate 15 in Utah and noticed smoke coming out from underneath my car. I pulled into a Firestone service center where they diagnosed the issue to be a faulty oil cooler hose assembly on my 2007 Toyota Sienna mini-van. I contacted Toyota dealer who said that the part had been upgraded from a rubber hose to a metal hose that would not burst like mine had. I was not informed of the option to upgrade prior to this incident and in fact had had my car into the dealer for an oil change the week before this incident. Firestone said I was down to two quarts of oil remaining in the oil pan. I feel lucky that I did not burn up my engine by stopping before the oil pan ran dry. Also, I am lucky that I was driving and not my wife with a car full of kids as there seemed to be a risk of a car fire based on the smoke. I am wondering now just how safe and reliable my car is and what other problems Toyota is aware of that they have not yet told me about on my year make and model. By the way it kind of ruined the family vacation we were just starting.

After a short trip, 5 miles, I was backing into my driveway when I noticed some fluids on the cement. I checked the liquid and was not sure if it was coolant or transmission fluids so I called my mechanic and he recommended that I should have it towed in.it turns out that the problem was that a connector at the bottom of the radiator cracked and was mixing the coolant with the transmission fluid, it appears that a defective fitting was the problem. It cost me $977.3 to replace the radiator and flush the transmission. My mechanic said if I would have continued driving with these 2 fluids mixing I would have damaged the transmission beyond repair for a bill of $3,000. More if this is a common problem on these cars people should at least be notified what to watch for or better yet repaired by the company.
