What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Driver's side airbag didn't deploy, but passenger's side air bag deployed. Driver sustained broken ribs.
While driving, consumer was hit in rear by another driver. Vehicle hit a meduim strip at 30 mph. Driver was injured. Two minutes later, driver's side and passenger's side airbags deployed.
While researching online, there are numerous complaints about a gas smell on these cars.
Engine began running badly and check engine light came on. Took to mazda dealer shop and was told a spark plug wire was defective and burned up. In actuality, the ignition coil had failed and caused the problems. The dealer replaced spark plugs, ignition wires, and coil.
No mention had ever been made of rust in the front frame rails. I pulled the front wheels to clean up rust and all connections and found patches of rust on both frame rails between the sway bar bracket and strut brackets. I can punch a screwdriver through the rust on the driver's side.
1999>2000 mazda miatas are known to have had a bad batch of coil packs put in them, resulting in the check engine light coming on, (has happened to me three times), not while driving, but upon restarting after a brief stop, like at a store, wherever.
Area of the front frame support rails (core support is official name) rusts from the inside out. The construction method is a sandwiched material with some sort of tarpaper in the middle which traps moisture which, in turn, hastens frame rusting.
1999 to 2000 mazda miata the wiring harness for the low/high beam has been shown to generate high temperatures and on one occasion, cause a fire. I personally have experienced this with my 1999 miata which prompted me to replace the forward section of the h4 headlight wiring harness.
