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 current issues ( which we believe are Mazda corporate issues) and inherent to this vehicle which has low, low, low miles have caused the engine to overheat and have resulted in an engine fire, twice, on the freeway: 1)faulty electrical parts: This vehicle has had the same electrical problems since the first day we brought it and has had multiple replacements of the electrical module, batteries, alarm system, and other items, which have proven faulty by Mazda. 2)shutter valve recall: Ours was inspected, but not replaced even though things were out of sorts. It was later deemed a problem. 3)faulty belts, due to engine overheating, which technicians have told us was from an overheating issue and potentially created by the inherent problems with the electrical system. 4)leaking radiator technicians have indicated this is due to the ongoing overheating problem we have been overwhelmed by the interchanges with Mazda personnel regarding a "lemon? vehicle we purchased in 2003 or 2004. Subsequently, we drive it minimally and it only had 30,000 plus miles on T within the 4 year, 50,000 warranty expired. That said, within 24 hours of purchase, the car had electrical problems. When in an ?off" position, the lights stayed on and the alarm sounded errantly and intermittently. The car ran hot, and had other issues we mentioned. The dealer replaced the electrical module and/or alarm system. The problems persisted. We brought the car in for inspection multiple times, and received multiple responses from service technicians: 1)nothing wrong 2)needed routine maintenance, oil, plugs, points, etc 3)multiple battery replacements due to dead batteries and draining issues 4)car out of alignment ( the car had 3 sets of tire replacements at 40K) 5)faulty belts ( we paid for replacement) 6)shutter valve ( recall was not replaced) 7)water pump leak 8)electrical issues not definable, but battery drains 9)engine runs hot and rough 10) fire in engine on freeway.

When driving at any speed vehicles unexpectedly died. Dealer determined that computer needed reprogramming. Two months later the engine died again. The vehicle was taken in for second time where they service dealer could not find the problem. On one occasion the powertrain control module was reprogrammed due to the vehicle stalling.
