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. Notes: Beware of the NHTSA complaint data for the 2007 Corolla. It is almost certainly misleading.

The problem with NHTSA data for the 2007 Corolla is that for months on end, the news media repeatedly told the public that several Toyota models have an unintended acceleration defect, & to go to (the NHTSA's website) to file a complaint.

So, the NHTSA received a disproportionate number of complaints about Toyota unintended acceleration issues because of the national news media attention, to the point where now the NHTSA data is unreliable taken in context with any other vehicle that did not receive national news attention. typically receives more complaints per day about vehicles than the NHTSA does, but the news media did not repeatedly say "go to to report your Toyota acceleration problems" like they did about the NHTSA -- so although we have less complaint data than the NHTSA for the 2007 Corolla, our data for the Corolla is a far more statistically accurate representation of the Corolla's reliability than what the NHTSA data shows.

Our son was driving my car at approx 55 mph, in the afternoon, in cool clear spring weather... a clunk was heard, the engine died, he was lucky to find a wide spot to pull off the rural two lane highway and coast to a stop. The vehicle was towed to a dealer, diagnoses revealed dtc 607 ECM performance, description computer, engine. The computer was defective, and was replaced with 1 quantity....fp number 89661-02K21 computer for the engine under warranty. (31,858 miles on odometer) thurston's dealership in ukiah gave us great service and a quick turn around time enabling son to commute to college once again with little inconvenience. I'm greatly concerned about this incident and hope my data submission will serve to alert service departments, manufacturers and investigators to our experience with the engine computer chip defect. I want to help prevent the possibility of other drivers being placed in a potentially hazardous situation of loss of engine computer control while driving.
