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.

Corolla 4-cyl

  • 33,000 miles


The contact owns a 2004 Toyota Corolla. While driving 45 mph, the vehicle began to hesitate and attempted to stall. The contact engaged the accelerator pedal so that the vehicle would not stall at all. The vehicle was taken into the dealer where they stated that there was excess carbon build up in the throttle body from a new battery that was installed. The dealer then performed a throttle body cleaning which removed the carbon build up. The contact stated that within the last 3 to 4 months the problem continued to occur. The dealer was not contacted and there have been no diagnostic test or repairs. The failure mileage was 33000 and the current mileage was 36000. Updated 12/03/10. The consumer stated it felt as though the engine was going to stall. According to the service invoice, the dealer stated the engine belt was glazed and the tensioner had lack of tension.

2004 Toyota Corolla drive belt cracked at about 5K miles I have a 2004 Corolla which is maintained regularly at darcars Toyota of silver spring, Maryland. When I had my car oil changed at mileage 53200, the service representative told and showed me that my car's drive belt has many, many cracks on it. They told me I need to replace it with a new belt and will be charged $210. Toyota officially recommends an initial inspection of drive belt at 60K/72 months, 15K thereafter. It means before 60K miles there should be fine. I sent an email to Toyota and asked them if my car has a quality problem. In their reply, they refused to answer my question. Toyota is famous for their vehicle excellent quality, but it looks not in my case.
