Mazda Miata MX-5 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mazda Miata MX-5

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.

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.

Failure of the valve cover gasket can allow engine oil to leak onto the spark plug wires and damage them. The engine will run poorly (misfire) if the spark plug wires fail.

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.

As the former owner of half a dozen British sports cars, I came across a great deal on a high mileage slightly beat up Mazda Miata. What a surprise! After doing several minor repairs and catching up on neglected maintenance by the previous owner I started to drive and enjoy my Miata more and more. I asked myself the question do I want to work on my British cars during the week so I could drive...

My Miata is an SE model with a 6 speed manual trans. It has 17,500 miles on it (Garage Queen). The only problem I've had is the clutch (chudders) and I can be difficult to shift into 5 and 6th gears at times. I replaced the trans. fluid with synthetic (Red Line) fluid. I also replaced the clutch fluid (SAE #3, brake fluid) and bleed the line. This has greatly improved the trans. shift p...

My 2004 Mazdaspeed Miata is my fifth Miata in 10 years. Every time Mazda upgraded the car, I traded up. The Mazdaspeed has a turbocharged engine, numerous suspension upgrades, and other go-faster goodies. It was sold in limited numbers for 2004 and 2005, and in special colors. Every Miata I've owned has been almost flawless in terms of reliability. My 2001 had a transmission issue fixed under...
