What 2008 Porsche Cayenne Turbo owners say
Engine & cooling
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.
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.
