2003 Mazda Miata MX-5 ProblemsCheck Engine Light Due to Restricted EGR System
The passages for the Exhaust Gas Recirculation (EGR) system can become restricted or clogged causing the Check Engine Light to illuminate. The EGR valve will need to be inspected and the passages cleaned.
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 clutch slave cylinder may develop a hydraulic leak resulting in no clutch pedal pressure and the inability to shift gears.

2003 Mazda Miata MX-5 RecallsFog Light Socket May Fall Out of Lamp Assembly
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.
