2002 Rolls-Royce Corniche
The 2002 Rolls-Royce Corniche, a pinnacle of luxury and craftsmanship, represents the final iteration of the classic Corniche line. Powered by a 6.75-liter V8 engine producing around 325 horsepower and substantial torque, it delivers a smooth and effortless driving experience. The engine is paired exclusively with a GM-sourced 4L80E four-speed automatic transmission. Owners often praise the Corniche for its opulent interior, hand-crafted details, and the unparalleled prestige associated with the Rolls-Royce name. However, potential drawbacks include the high cost of maintenance, complex systems that can be prone to age-related failures, and the challenges of sourcing specialized parts for such a limited-production vehicle.

- Recalls: None Found
- Battery Drain
- Description/Symptoms: The battery repeatedly drains, even when the car is not in use. This can be caused by a parasitic drain from a faulty electrical component or a failing alternator.
- Solution: Diagnosis of the electrical system to identify the source of the drain. Repair or replacement of faulty components or the alternator.
- Estimated Cost to Fix: $200 - $1,000+
- Recalls: None Found
Exterior
