The drains in the Cabriolet top can clog, causing water to leak onto the carpets. Water can also accumulate in the doors, causing various electrical problems.

If the vehicle cannot return to run position after start or if the interior fan is not getting power, it may be the electrical portion of the ignition switch has become erratic or has failed. The entire switch assembly should be replaced.

Smoke, oil consumption, and fuel trim issues with various fault codes can be traced to an internal leak at the oil separator.

Windows and interior trim can be prone to squeaks and rattles. Numerous, small adjustments may resolve the issue. Additional creaks have been attributed to front and/or rear window fit as well.

Persistent coolant loss can be caused by a small leak at the coolant reservoir. Our technicians tell us the leak may not be visible due to the trunk carpet hiding the leak.

Engine vacuum leaks can develop from various locations resulting in illumination of the Check Engine Light.

A failing mass air flow sensor or EVAP purge valve can cause misfire issues.
Electrical issues—windows lowering after locking or leaving the vehicle—can be caused by a defect in the window motors.

Engine oil leaks can occur at the rear main seal and/or intermediate support cover o-ring; a revised seal is available. A careful diagnosis with proper tools is necessary to verify dimensional accuracy of the crankshaft to engine block.

Valve cover leaks are common.

If the airbag warning light illuminates, it must be attended to quickly. Seat belt buckles, wiring updates/repairs, and airbag module faults may be the cause.

Depending on driving habits, brake pad and rotor wear can be excessive. Our technicians recommend regular brake inspection to avoid having the pads wear out and damage the rotors. 

Cam tensioner/cam timing issues can cause the Check Engine Light to illuminate.

To ensure engine longevity, coolant loss and overheating issues need to be resolved. Coolant loss—sometimes slow and accompanied by white smoke—is often a sign of internal engine problems. The proper coolant fill procedure must be followed.
Over time, the engine carrier or the rubber portion of the front engine mount yoke can fail.
