2008 Porsche Cayenne Turbo Engine Problems

“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. …”

“While driving on the freeway my temp gauge started climbing and the low coolant light came on. I immediately pulled off of the freeway and had the car towed to a Porsche mechanic. He later identified the problem as the pipe or tube that connects to the water/coolant distributor came loose spilling all of the coolant out, which could of LED to a catastrophic engine failure while on the freeway. Not sure what the cost is going to be yet. My mechanic said he's seen this failure on 957 cayenne v8s many times. This is a dangerous thing to have happen on the freeway.”

“In 2010, I bought a '08 Cayenne Turbo at 40k miles. Prior to delivery, I had Porsche dealership run a system check to confirm the vehicle was mechanically solid & free of defects. Subsequently, they performed a repair on the coolant pipes (still under factory warranty) and assured me it was in excellent condition to purchase. 105k miles: cayenne's starter was making noises and not functioning 100% of time, so I brought vehicle to the same Porsche dealership who had been servicing it since 2010. The starter was immersed in coolant. …”

“Under moderate acceleration a coolant distributor pipe failed without warning and sprayed/leaked coolant all over the engine bay and underneath the car. The failure occurred at the back of the engine where a pressed in pipe fitting came loose from the engine casting. Repair required removal of the engine at a cost in excess of $3.500. All the coolant was lost from the engine and luckily I was on a side street and not the highway.”

“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.”
