Snapped aluminum camshaft sensor bolt resulted in total engine failure. This is a known issue by Porsche ag has resulted in an amendment in an existing service bulletin (wc-22) and also a recall of over 14000 Cayennes and panameras in china.

The screws holding my camshaft actuator failed and I experienced immediate engine lose as well as braking lose due to no vacuum. At the time of my engine failure it was a known issue for Porsche (see wc-22) whereas they did not make public aware or proactively fix the issue. This ended up costing me approximately $7500 out of pocket (in addition to several emotional damage due to financial constraints and the immediate danger when the engine failed at highway speed in the far left lane). Porsche has subsequently issued a recall (recall ah-08 and NHTSA campaign 17v368000) but had not contacted affected owners yet. I'd like a full refund of my expenses plus interest. I also feel they should be fined or pay impacted owners like myself a penalty due to their improper mishandling.

The car stopped while being driven in traffic on a busy suburban road. The car would not restart. Right before the car suddenly stopped the psm light came on. This was the only thing that occurred prior to the sudden stop. The car was pushed out of the road and flat bedded to paul miller Porsche in parsippany, n. J. The service technician(s) found that at least one aluminum bolt from the cam shaft adjuster had sheared off and fell through the engine causing complete engine failure. The only way to repair the car was to replace the engine. The car was purchase brand new on June 15, 2011. The car had been special ordered several months prior to the delivery date. After this incident, I researched this issue. It appears that Porsche Cayennes and panameras manufactured during the same time period our car was made were recalled in china for this exact same issue-aluminum camshaft adjuster bolts shearing off into the engine and causing total engine failure. This car was out of the Porsche 4 year/50k warranty period. I notified Porsche north America of this incident and they refused to replace the engine. The car was covered under our geico mechanical breakdown insurance. Geico sent out inspectors to examine the car and deemed it a total loss. We surrendered the car to geico and were paid what they deemed the car was worth. The last time we saw the car was at paul miller Porsche in parsipanny, n. J. On July 26th when we emptied it of our personal belongings. Luckily no one was hurt in this incident. Obviously a car suddenly stopping while being driven is huge danger. Had this occurred on a highway or in faster traffic the results could have been catastrophic.
