Engine stalled while driving. Car taken to Porsche dealership where they determined the camshaft controller needed to be replaced as it was broken. Paid $4000 in repairs in 2016.

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.

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 drov

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.

While driving on the road in a remote national park, the tubing that returns coolant to the engine block from the radiator on my 2011 Porsche cayenne s completely blew apart. This aluminum to aluminum tubing connection appears to have been held together exclusively by a thin, incomplete ring of epoxy glue. This is grossly substandard engineering for any such vital connection within the engine. Porsche has neglected to repair this known issue in model years such as mine, but has changed its design in the subsequent model years (likely because they realized this was dangerous and substandard engineering). They have not sent out any bulletin or recall to advise drivers of this defective construction or preemptively repair it. I was left stranded in a desert where I had to walk for hours to g

When rolling slowly (<15mph) 1-2 second stall/bog after pressing accelerator before car accelerates, creating a major safety issue esp when merging with traffic, changing lanes, etc. *tr Porsche north america denies this is a problem after inspection and says its "performing to specification". Separately, several Porsche dealers have verbally acknolwedged and/or confirmed this issue and call it a "first year" hybrid model problem.

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 sam

The original Porsche leather upper dashboard has shrunk, causing exposed staples, and rippling of the leather , including rippling and bunching of the leather that is covering the passenger dash airbag assembly. I have been informed that in the event of an accident causing airbags to deploy, the passenger airbag would likely not deploy correctly, and further injury could also occur because of exposed staples and hardware that should not be exposed. My Porsche dealer and independent dealer have both advised replacement of dash (for a very large sum of money). I have also taken the vehicle to multiple upholstery shops and all have declined to fix the problem solely due to the airbag risk/liability. This is very common issue for late model porsche full leather option dashes, and specifical

Porsche dash material is separating from the substrate of the structure. This material is directly between the airbag and the now loose material on the surface of the dash (leather). Porsche will not repair this and recommends a replacement at an estimated $10,000 USD. There is a significant risk to safety as the now loose upper material will interfere with the deployment of the airbag on the passenger side, adding potential harm and injury to a passenger inside the vehicle.

The leather on my Porsche Cayenne dashboard has shrunk and is pulling away from the front of the dashboard. My mechanic tells me that this is a possible safety issue because if the vehicle is in an accident, the front passenger airbag may not deploy correctly and recommends replacing (expensive). In checking various Porsche online forums, this appears to be a common issue among owners with the more expensive leather dashboards.

Tl* the contact owns a 2011 Porsche cayenne. While driving various speeds, the contact depressed the accelerator pedal and the vehicle started to jerk. There were no warning indicators illuminated. The vehicle was not taken to a dealer to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 80,000.

Transfer case failure. There is an acknowledgment by Porsche of an associated defect of the transfer case design and a related workshop bulletin (wb) when replacing the transfer case. Porsche mechanics are instructed to replace a "vent hose" for the transfer case. This newly revised design part number for the revised vent is 958-301-047-10. The reason: the original design for cayenne 958 Porsche transfer cases had the hose ending on the lower (closer to the ground) side of the transfer case. The new hose ends on the upper (further from the ground) side of the transfer case. Porsche determined that moisture was getting sucked into the cases and causing fluid contamination. Since the transfer case uses a "multiplate wet clutch", moisture could prematurely corrode or allow rust to form, which

Transfer case has failed, jerking and interruption of accelerations. Almost caused a wreck. Very well known problem and there are a lot of similar complaints on the NHTSA complaint log system as well as documented online. I called Porsche and they denied knowing about any problem with it but you can call the service departments at any Porsche dealer and they immediately know about the problem. I called two and they know of it as a common problem. Extremely expensive to correct ($5,000).

At highway speeds, randomly a serious unsafe to operate 'service necessary' warning appears on the instrument panel and the cruise control malfunctions; abruptly shutting off. With the service necessary warning indicated, the vehicle is unsafe to operate. This unsafe vehicle is not drive-able with cruise control. Error will go away on its own. This breakdown appears to be known to Porsche based on what I have seen on internet community sites

The factory programming of the computer and speed control is incorrect. Porsche states that the vehicle is operating within characteristics and specifications [and according to us law a variance of up to 18% is allowed in the speedometer.] however, Porsche has taken the us law to mean that it is allowed to intentionally program its computers to the same specifications as analog gauges. Porsche cannot demonstrate that the inaccuracy in the speedometer is not effecting the hybrid operations of the vehicle. The inaccurate speed reading may also create inaccurate odometer readings. In addition the vehicle has problems with hard braking which is especially pronounced when the vehicle is under cruise control. And in certain instances there is lag on acceleration. Porsche has refused to reprogram
