I recently purchased a '03 mazda protege5. while driving down the road yesterday at 65 mph, i heard a loud bang and heard something hit the bottom of the car. the car exhaust suddenly became much louder. i immediately pulled off the road. i looked under the car, and the exhaust had come apart. the piece of the exhaust after the cat was hanging about 1 inch from the ground. this piece is after the catalytic converter, near one of the hanging points of the exhaust system. two bolts, which hold this piece together, and the exhaust gasket were missing. luckily, there was no damage whatsoever. this problem could have ended tragically. *tr

On at least 3-5 occasions this 2.0l engine has suffered the exact same fate as nhtsa id# 10422484. check engine light on, misfiring, associated noise sounding like a bolt / screw bouncing around in the engine for maybe 15 seconds, then would return to normal. each time there has been a different cylinder misfire, upon spark plug removal it was found the gap was closed causing no spark. each time, a new plug was installed and corrected the immediate problem. after seeing these complaints and a recall regarding this issue i realized i've had the same issue. don't know if my vin # is in the effected range or not. car now has 123105 miles. would hope that mazda would cover any vehicle with this problem. *tr
