general problems of the 2008 Porsche Cayenne

Coolant distributor barb came unglued causing loss of coolant on highway. Car was in motion on the highway. This is a common issue and Porsche has updated the part however will not warranty the defective parts still on vehicles.

Engine rough idling which dealer cannot diagnose.

Parked vehicle and attempted to turn off got a red alert steering faulty,everything locked up including transmission and window switches. . Had to be flat bedded to a Porsche dealership took a week for them to figure out,had to replace steering column. Concern is what would have happened if driving at the time. . Got no answer.

Tl the contact owns a 2008 Porsche Cayenne s. While driving various speeds, the engine warning indicator illuminated. The vehicle was taken to an independent mechanic who diagnosed that the fuel, high pressure, and pressure pumps failed and needed to be replaced. The vehicle was not diagnosed or repaired by a dealer due to the cost. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a recall. The contact was referred to NHTSA. The approximate failure mileage was 120,000.

The distributor collector coolant systems including the pipes has failed. However, I have been informed by the Porsche corporate office there are no complaints or recalls on file. Unfortunately, they were unable to provide the number of complaints for this make/model/year. On the date of the incident I was driving the vehicle and the coolant light appeared (no other symptoms), I did not hit a bump, it was all of a sudden when my vehicle began to smoke as if it was on fire.

While driving, all of the sudden felt a strong coolant smell, slowed down immediately and drove home. Upon further investigation it was discovered that the coupling pipe that inserts into the water distributor was coming out. The glue that held the pipe in place failed and the pipe was 60% out! I stopped in time before the pipe completely blew out and sudden loss of coolant occurred, the pipe was literally finger tight, nothing held it in place anymore. Porsche quotes $3500 to repair!!!! this needs to be a service action clear as day.

Sudden and total coolant loss when coolant distribution housing pipe came apart while driving on a public roadway resulting in disabled vehicle. Part # 948-106-061-06 distributor tube failure at bottom connection. Required to remove engine and replace coolant distribution housing.

I purchased my 2008 Porsche Cayenne turbo as a second owner but before the purchase was completed the coolant hose rupture failure occurred. The repair was at a cost well north of $2000 at the motor werks Porsche of barrington. I also have a 2002 Porsche 996 turbo which just recently ruptured the coolant hose. The cost is once again right around two thousand dollars. I'm just fed up that this epoxy failure within the coolant system which has affected so many Porsche owners. I'm very disappointed that this issue is not fixed even in their later models but very happy to find out that maybe something will arise with these complaints.
