Known Issues
Nb Common Issues Overview:
While generally reliable, some common issues include: oil consumption in higher mileage engines, worn clutch components, aging rubber bushings, power window regulators failing, and convertible top fabric degradation. Radiator and cooling system maintenance is important.
Nb Engine Oil Consumption:
Some NB engines, particularly with higher mileage, may exhibit increased oil consumption due to wear in piston rings or valve seals. Regular oil level checks are crucial.
Nb Rear Main Seal Leaks:
Rear main seal leaks can occur, requiring transmission removal to address.
Nb Convertible Top Leaks And Wear:
Older convertible tops can develop leaks, and the mechanism can require adjustment or lubrication. The rear plastic window can yellow or crack.
