What Problems Does the 1994 Mazda RX-7 Have?
The 1994 Mazda RX-7, while exhilarating, is known for several frequently reported problems and long-term reliability concerns, primarily stemming from its unique 13B-REW twin-turbo rotary engine. The engine's apex seals are a critical wear item, and their failure often necessitates an expensive rebuild. Owners commonly report high oil consumption, which while somewhat normal for a rotary, can indicate seal wear if excessive. Heat management is another significant issue; the engine runs hot, and a compromised cooling system can quickly lead to catastrophic failure. Aftermarket cooling upgrades are highly recommended.
The complex sequential twin-turbo system is a frequent source of trouble. Vacuum lines, solenoids, and control units can fail, leading to inconsistent boost, "limp mode," or a complete loss of secondary turbo function. Turbocharger seals can also fail, resulting in excessive smoke from the exhaust. Age-related issues are also prevalent, including cracking of plastic components in the engine bay, deteriorating rubber hoses, and brittle vacuum lines.
Electrical problems, such as flickering or faded gauge cluster lights, failing power window motors, and various sensor malfunctions, are not uncommon. Suspension bushings and other chassis components often require replacement due to age and spirited driving.
Several recalls impacted the FD generation, including the 1994 model:
Prospective buyers should prioritize models with extensive maintenance records, particularly evidence of engine rebuilds by reputable rotary specialists.
