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.

2003 Toyota Prius Owner Comments

problem #1

Jul 212010


  • Automatic transmission
  • 100,000 miles


I had my Prius towed in to the dealer in July 2010 because it wouldn't stay running. I paid over $400 for it to be fixed (idle throttle body). In Sept. 2010 it did the same thing again. I had it towed (again) to the dealer, and now they tell me the inverter/converter is dead, basically, and needs replaced, as it runs the entire hybrid system. Cost?- around $3500. Why didn't this show up in July? Because the machine that diagnoses the problems didn't tell them it was failing. Toyota offered help in the form of $1000 towards the cost, or I could trade it in for a new one and they'd make me a good deal. I declined, and offered to sell it to them back, and they refused.

So now it's being fixed and I'm out $3000, time without the car, and paying for a repair that I feel should have been found on the original breakdown. Do we have any mechanics out there who can look at a car and see what's wrong without a machine to tell them?
