Known Issues

Engine Wear:

Potential for piston ring wear or oil consumption in high-mileage engines, common in many naturally aspirated V6s of this era. MIVEC system can be sensitive to oil quality and maintenance.

Transmission Reliability:

F5M42 manual transmissions are generally robust but clutch wear is a consumable. F5A42 automatic transmissions can develop issues with valve body solenoids or clutch packs if not properly maintained with fluid changes.

Electrical Components:

Age-related issues with wiring harnesses, sensors, and the ECU can occur, as with any vehicle of this vintage.

Suspension And Brakes:

Wear on bushings, ball joints, and brake components is typical for a performance-oriented coupe of this age. Regular inspection and replacement are necessary.
