  Structure › Body

  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

  Driving my 2004 mazdaspeed miata on the highway and the engine suddenly stalls. the problem was the fuel pump failure. I bought my car new and it has 4,400 miles on it. I had three fuel pump failures since 2004. I complained to the mazda dealer as to why this IS happening but they don't have a clue. *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

Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.

• 11006987In accordance with Federal regulations, follow the procedure listed below when replacing a speedometer. NOTE: Tampering with a motor vehicle odometer is strictly prohibited by Federal, and State laws. It is the dealers responsibility to comply with Federal, State, and local laws concerning odometer and related documentation requirements when providing a repair or replacement. Mazda vehicles are manufactured with tamper-proof speedometers. When a speedometer is replaced, the new speedometer will read zero (0) miles. This procedure is extremely important to accurately represent actual vehicle mileage. Prior to speedometer removal, complete the information required on the Speedometer Replacement Label. Labels can only be ordered through Mazda eStore. In an effort to achieve a higher level of Customer Experience and retain the value of Mazdas vehicles, MNAO Warranty Operations is allowing all Mazda dealers to utilize a third party, SPECMO Enterprises, Inc., for Instrument Panel Cluster (IPC) odometer setting service. With the use of SPECMOs services, it is possible that the odometer will be set between 10 to 31 miles over the odometer mileage at the time of replacement for both warranty and customer pay repairs. Please make sure that the customer is aware that there may be a slight variance to the odometer, in which case the customer may have to accept the slightly higher mileage. Since odometer setting service is not part of the warranty repair, it is not warrantable nor required, but optional. However, Mazda Warranty policy provides after- warranty assistance (AWA) or DSA that can be utilized to cover this service expense.
