What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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.
I received another call a few days later informing me that my cayenne now had a second coolant leak at the crossover pipe toward the back of the engine near firewall (required removal of the engine in order to repair).
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.
