Known Problems

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.

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.

Symptoms such as dragging or a stiff pedal can be caused by accumulated water entering the brake booster. The root cause is a plenum drainage issue. Updated parts are available for early-production vehicles.

Abnormal noises from the intermediate shaft area may be signs of impending engine failure, don't wait to get this issue checked out!
