According to RepairPal, one common issue that Mazda RX-7 owners may face is an oil leak developing at the rear stationary gear seal and O-ring. This seal and O-ring are located in the engine and are responsible for preventing oil from leaking. However, the seal and O-ring can become worn or damaged over time, causing oil to leak out of the engine.

The issue is reported to affect model years from 1990-1995. If left untreated, this oil leak can lead to engine damage or even failure. Therefore, RX-7 owners must be vigilant and address any oil leaks as soon as they are detected to avoid more serious issues.

Another common issue reported by Mazda RX-7 owners is intermittent no-start, particularly in the turbo models. According to RepairPal, this problem can be caused by a malfunctioning engine control module (ECM). The part controls various aspects of the engine’s operation. When the ECM malfunctions, it can prevent the engine from starting even though it is cranking normally.

Other possible causes of intermittent no-start can include fuel, ignition, or starter issues. Diagnosing and fixing this issue can be challenging and may require the assistance of a qualified mechanic. However, addressing this problem promptly is crucial to avoid getting stranded unexpectedly or causing further damage to the engine.

The anti-lock braking system (ABS) is an important safety feature in any car, including the Mazda RX-7. However, some RX-7 owners have reported that the ABS light can illuminate intermittently, even when there are no problems with the braking system. According to RepairPal, this issue can be caused by a faulty ABS control module or sensor. The faulty sensor can trigger the warning light to turn on even when there is no problem with the brakes.

It is important for Mazda RX-7 owners to address this issue promptly. Malfunctioning ABS can compromise the car’s braking performance. This can potentially lead to dangerous situations. A qualified mechanic can diagnose the root cause of the problem and determine the appropriate course of action to resolve the issue and ensure the ABS is functioning correctly.
