    THE FORWARD FRAME RAILS ARE SEVERELY RUSTED, COMPROMISING THE FUNCTION OF THE BUMPERS GREATLY INCREASING THE LIKELIHOOD OF INJURY IN THE EVENT OF A FRONT COLLISION. CORROSION IS NOT READILY APPARENT, SUGGESTING THAT MOST PEOPLE ARE UNAWARE THAT THEIR VEHICLE'S SAFETY HAS BEEN COMPROMISED.

    THE CAR HAS A INTERMITTENT PROBLEM RUNNING, IT HAPPENS WITHOUT WARNING. LAST TIME IT HAPPENED I WAS ALMOST RUN OVER BY A 18 WHEELER. I HAVE MENTIONED IT TO THE DEALER AND NO RECALL EXISTS THIS PROBLEM IS WIDESPREAD ON THIS MODEL AS NOTED BY MEMBERS OF MIAT ACAR CLUBS. BECAUSE THE MANUFACTURER WILL NOT OWN UP TO THE PROBLEM EXTENSIVE TESTING HAS BEEN DONE BY OUR CAR FORUM. REPLACING THE MAP SENSOR CURES THE PROBLEM FOR ABOUT 90 DAYS BUT AT 100 DOLLARS A POP IT IS A LITTLE EXPENSIVE. CARS THAT HAVE HAD THIS PROBLEM HAVE BEEN MODIFIED TO RUN WITHOUT A MAP SENSOR AND THIS HAS CURED THE PROBLEM. UNFORTUNATELY THE CURE IS 2000 BUCKS. I HAVE BEEN HAVING THIS PROBLEM FOR 2 YEARS NOW AND WOULD LIKE SOME HELP FIXING IT. *TR

    CAR WOULD NOT ACCELERATE. I CAME TO A STOP AT A TOLL BOOTH. WHEN I WENT TO PULL AWAY THE CAR WOULD HARDLY ACCELERATE. ANY AMOUNT OF THROTTLE WOULD CAUSE THE CAR TO BOG OUT. SEEMS VERY LIKELY A CRASH COULD OCCUR IF THIS PROBLEM HAPPENED AT THE WRONG TIME. THIS IS SPECIFICALLY A PROBLEM WITH THE MAZDASPEED MODEL OF THE MX-5. *TR
