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.

2003 Mazda Protege Owner Comments

problem #1

Mar 252009


  • 83,000 miles


The 2003-2003.5 mazdaspeed Protege poorly designed limited-slip differential has seen a failure rate of over 125 documented cases online. When this part fails, the vehicle does not respond to acceleration causing a safety issue at highway speeds and residential speeds. When this part fails, it could cause the vehicle and passengers to be at risk for roadside rear end crashes due to loss of power especially if the driver is changing lanes at highway speed. This issue has been a widespread problem for this particular model and Mazda usa has denied any responsibility for issuing a recall. 2003-2003.5 mazdaspeed Protege owners have had the limited slip differential replaced only to find the issue re-appear and fail again. Here is a link to the documented list of owners who have had this fail. ( Some failures have even been dangerous. I would ask that the NHTSA look deeply into this situation before someone gets hurt or worse. Thank you for your time.
