Late 2010 to early 2012 Porsche Cayenne vehicles with v8 engines have a manufacturing defect with bolts that hold the camshaft adjusters. The weak bolts in question are made of aluminum and have been experiencing failures where they sheer off, causing catastrophic damage to the engine. If this failure occurs when the vehicle is at speed, a loss of power braking and steering will occur as a result. Porsche is aware of the problem and was forced to recall all the affected vehicles in china by the chinese government, but has so far avoided recalling the affected vehicles in the us. The necessary repairs involve replacing the defective bolts with steel ones. Porsche no longer uses the defective bolts in their v8 engines built after 2012. I believe Porsche will not address this defect properly in us cars unless an investigation is launched with the possibility of a recall. Repair costs per vehicle are estimated at $3500, compared to $30,000 for the cost of a complete replacement engine. There are numerous websites with users explaining the problem and limited remedies. . Read more...

Camshaft adjuster bolts starting to become loose and back out, which is a known manufacturing defect on those cars, can lead to sudden unpredictable loss of steering and braking, and potentially accidents, especially with very heavy and very fast car like this one. Dealer quoted $4000 to fix with new bolts and adjusters. Attached are pictures taken with a borescope from my engine. I am scared to drive it. This should be a recall. Owners should not be paying for this. Also attached is quote from dealer.

I was pulling forward on a level city street and turning left from a stop sign. There was a significant amount of shuddering and feeling of a loss of power. This was a significant safety issue due to oncoming traffic. Over a period of several months this had been increasing in severity but the dealer could not identify the problem. I took it to the dealer and was able to repeat the problem for them. They identified the transfer case as the issue. It was replaced. I also had to replace the tires due to the dealers identification that the transfer case had caused differential tread wear damage to a rear tire. As a former military aviator, there is no doubt in my mind that this is a safety issue. Porsche needs to identify what the issues are (design, manufacturing, servicing, etc) and remedy them. Surprisingly, this is a known problem because the service adviser informed me that they keep transfer cases in stock. They retail for $3944, plus the new vent kit (mine does not have it) and then add labor, and tires if they have been damaged. That is a lot of expensive inventory to have on hand if Porsche wants to claim there is not a problem.

Camshaft adjuster bolts snapped while in operating mode. Being made of aluminum not steel as in previous years caused the engine to stop operating. Porsche USA refused to cooperate citing an out of warranty reason. Vehicle onlu had 84000 miles when this factory defect has effected the engine.

Faulty camshaft bolts in early v8's of this generation (2011 models) resulting in loss of engine power, and sometimes brakes. Vehicle broke down in the middle of a busy road, luckily was not at highway speed or it could have been very dangerous.

There have been increasing reports of variocam camshaft drive bolt failures on the 2011 Porsche Cayenne v8 engines. When these bolts fail, engine damage occurs, and the engine typically stops running. In the case of the turbo model - this can also result in the loss of braking ability since the brakes are powered off a camshaft. There is also a loss of power steering - meaning you have a 4,500lb vehicle without brakes or steering. Porsche had a limited "workshop campaign" for these vehicles that addressed a certain range of VIN# in the USA. It is wc-22 (I'm attaching a pdf of it. ) the failures are now being reported with increasing frequency in VIN#'s not covered by this workshop campaign. The campaign involves replacing the variocam assembly with one assembled with steel bolts rather than aluminum bolts. Earlier versions of this assembly also used steel bolts, and the failures appear limited to ones where the aluminum bolts were used. . Read more...
