Mazda Miata MX-5 ProblemsCheck Engine Light Due to Improperly Manufactured Threads on Fuel Filler Pipe
Some models may have a problem where the Check Engine light illuminates indicating an improperly tightened fuel cap. Due to improperly manufactured threads on the fuel filler pipe, the filler pipe may need to be replaced.
A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.
The engine may idle roughly or stall when it's cold because the oil pump pressure relief plunger is sticking. Failure is usually due to wear and it causes excessive oil pressure to pump up the hydraulic valve lifters keeping the valves from closing completely, which results in a loss of compression. The oil pump will need to be replaced in this case.

Mazda Miata MX-5 RecallsHorn Contact May Separate from the Steering Column During Airbag Deployment
If the driver's airbag were to deploy in an extremely low ambient temperature, the bolt attaching the horn contact assembly to the steering wheel hub may fail. Should this occur, the horn assembly may separate and could injure the driver. Dealers will replace the driver's front airbag to correct this concern. The Mazda recall number is 3906C.
The heat generated by a fog light bulb can cause the socket holder to be pushed rearward in the light casing. This, in combination with the normal vibration during vehicle operation, can cause the bulb holder to separate from the light casing. Should this occur, the bulb socket and harness can drop inside the bumper and possibly result in the bumper being burned by the hot bulb. Dealers will install a spring to prevent the socket holder from separating from the lamp case. The Mazda recall number is 1103F.
