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 contact owns a 2004 Mazda3. She stated that the vehicle could be driven as an automatic or a manual. While driving 20 mph in manual mode she attempted to shift gears, to no avail. She had to take her foot off of the gas pedal in order for the gears to release and afterwards the gears started to shift on their own. She was able to exit the freeway when the vehicle lost all power, but continued to accelerate. She was unable to stop the vehicle or make a turn. The vehicle began moving from one lane to another and accelerated through a red light to avoid a collision. The vehicle stopped accelerating within in a few minutes. The vehicle was towed to a local mechanic who diagnosed the failure as the intake manifold. The intake manifold melted, damaged the sensor and the catalytic converter. The mechanic replaced the catalytic converter, sensors, and the gaskets; however, she had to add oil to the engine because the engine light illuminated constantly. She took the vehicle back to the mechanic who stated that the engine also needed to be replaced. She contacted the manufacturer and filed a report; however, the manufacturer stated that they would not assist with the repairs. The engine was not replaced. The failure mileage was 25,000 and the current mileage was 75,000.

There were no major events that lead up to the failure, just normal commuting back and forth to work. The failure was my passenger side engine mount, which failed completely, 1 occurrence which happened just outside of the warranty window. No immediate side effect but long term ramifications due to stresses placed on other motor/transmission components still unknown. Motor mount purchased and replaced by myself. Old part not available.

Request for reimbursement for replacement of vehicle. The engine and power transmission shifted hard from 3rd to 4th gear and while doing so there was subsequent over -rev of the engine at any speed while in 4th gear when the accelerator was depressed in 4th gear. This would become a no-control situation.
