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.

The brake doen't work when I was driving out of the highway. I pressed hard of the brake and cannot stop the car. And I crushed into a big truck. The car crushed once with the truck and the momentum made the car to hit the traffic light pole again. Terrible.

Sunday Dec. 11th: Pulling out of Chicago garage, car makes odd rotational noise. The sound seems to go away after about a block or so of driving. The dealership is closed and I am booked up with clients, so I continue to test and see if temperature or environment effect the noise. The noise appears to only happen on a 'cold start' but all other factors do not seem to show an impressive change. Dec. 15th: I call Toyota corporate and file a complaint, then per their direction, call the dealer and make an appointment to have the noise problem fixed. Jan. 13th: After several calls to corporate, and having taken the car in three times to the dealership (midtown Toyota- Chicago), I have been informed by one of the service employees that Toyota is having a problem with many of these models. They think it is a back brake issue, perhaps defective part(s). As both Toyota & the dealership are not officially telling me this. This is what I know, they have been lying to me as a consumer and me and other customers are driving a car with a potential safety problem. I do not feel safe driving this car.
