Summary

The 2001 Rolls-Royce Corniche, while a symbol of luxury, can present owners with a range of potential issues, largely due to the vehicle’s age and complex systems. Engine issues like valve stem seal failures and coolant leaks can be costly to address. Transmission problems with the GM 4L80E can also be a significant expense. The self-leveling suspension and convertible top mechanisms are additional areas where failures are common and repairs can be pricey. Overall, owning a Corniche requires a significant financial commitment for maintenance and repairs, emphasizing the importance of a thorough pre-purchase inspection.
