2011 Porsche Cayenne. Consumer writes in regards to car stalling while driving. The consumer was advised no fault codes appeared. The vehicle stalled and drifted into a curb bending and damaging the front wheels. The check engine light illuminated.
Major engine failure -related to defect identified in voluntary workshop campaign wc-22-in the aluminum camshaft adjuster bolts which have a tendency to sheer off, which prevent the camshafts from running. If this occurs in the camshaft that operates the vacuum pump, the power braking will also fail, which will result in an extremely dangerous situation especially if the driver does not have the strength to brake the car without the vacuum powdered brakes. The bolts themselves may also drop into the engine and cause the engine to fail. In my case vehicle had dealer routine service check 3-4 days earlier- everything "perfect". On day of failure stopped for gas and after restart heard a new "ticking" and check engine light came on. I called dealer who instructed me to come over. I drove about 3-4 miles to dealer new psm failure and another I did not get when car lost power and seemed to brake poorly. . Rolled into dealer and still there- engine pulled --may be complete loss. Dealer acknowledged today this is the same issue as wc-22.
