Common 1991 Mazda Mx-5 problems

The Mazda MX-5 Miata, produced in 1991, is a popular roadster known for its fun, nimble handling, and reliability. However, like any vehicle, it is not without its common problems. Here are some issues that 1991 Mazda MX-5 Miata owners have reported:

• Seatbelt Problems: Over time, the seatbelts in the MX-5 Miata can become harder to pull out and may not retract fully on their own. This is due to dirt buildup on the belts, especially since the car is an open-top vehicle. The solution is to remove the seatbelts from the vehicle, clean them with hot, soapy water and a brush, and allow them to dry thoroughly before reinstalling them.

• Fuel Pipe Problems: Some owners have reported that the fuel system can become extremely slow to fill, with the pump clicking off frequently and the tank stopping any more fuel from being added despite not being close to full. This issue can be resolved by replacing the fuel tank, the fuel filler pipe, and the breather pipe. While it may seem like a daunting task, the procedure is covered in detail in the Haynes Miata manual.

• Shock Absorber Problems: The Mazda MX-5 Miata is known for its excellent handling, but this can be compromised if the shock absorbers lose their oil. Replacement is the key to restoring the car's handling capabilities.

• Short Nose Crankshaft: Some first- and second-year Miatas suffered from defects in the crankshafts that could negatively affect timing, eventually grenading the motor. Most of these "short-nose crankshaft" engines have either been repaired or replaced by now, but it's still something to watch out for.

• Plastic Windows: The plastic windows in the vinyl soft tops can dry out over time, blurring transparency and developing cracks. Fortunately, it's not too difficult to replace them yourself with simple tools on a weekend.

• Airbag Control Module Failure: It's not uncommon to see an airbag light illuminated in the gauge cluster due to a failed airbag control module. The module sits under the dash and costs around $100 to replace.

• General Maintenance Items: As the MX-5 Miata ages, it's essential to inspect more general maintenance items like rubber hoses, suspension bushings, and electrical connections, as those can wear out and fail, causing headaches down the road.

These common problems should be considered when purchasing a 1991 Mazda MX-5 Miata. However, with proper maintenance and care, these issues can be minimized or resolved, allowing the driver to enjoy the car's fun and nimble handling for years to come.
