TCS:

Traction Control System (TCS) was available on some models, utilizing ABS sensors to manage wheelspin.

Oem Diagnostics:

OBD-I diagnostics port (self-diagnostic system) providing basic fault codes, requiring specific procedures or breakout boxes for full access.

🔧 Maintenance

Oil Change Interval:

Every 3,000-5,000 miles (5,000-8,000 km) or 6 months, whichever comes first (highly dependent on driving conditions and oil used; shorter intervals are often recommended for rotary engines).

Spark Plug Replacement:

Typically every 15,000-30,000 miles (24,000-48,000 km), often requiring specialized spark plugs designed for rotary engines (e.g., two plugs per rotor).

Coolant Replacement:

Every 2-3 years or 30,000 miles (48,000 km).

Timing Belt Replacement:

Not applicable (rotary engines do not have timing belts; they use eccentric shafts and chains/gears).

Brake Fluid:

DOT 3 or DOT 4, depending on original specification and ABS system requirements.

Power Steering Fluid:

ATF Dexron II or equivalent.

Apex Seals:

Wear and failure of apex seals (critical components in the rotary engine's combustion chamber) due to overheating, improper lubrication, or detonation. Regular checks of compression are vital.

Cooling System:

Overheating issues can arise from inefficient radiator design, faulty thermostats, or blocked coolant passages. The rotary engine generates significant heat.

Turbochargers:

Reliability of the sequential twin-turbo system, particularly the smaller primary turbo, can be affected by heat and wear. Actuator issues and wastegate problems are not uncommon.

Emissions System:

Early models had complex emissions control systems. Issues with vacuum leaks, EGR valves, and air injection systems can affect performance and drivability.

Fuel System:

Clogged fuel injectors, worn fuel pumps, and issues with the fuel pressure regulator can impact engine performance.
