Radiator Problems of Porsche Cayenne

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 get help and had to have $1000 tow to the nearest city, all because of this dangerous design and construction of which Porsche is already aware.

While driving under normal driving conditions the check/add coolant alarm/icon appeared in the dash display. After letting the vehicle cool down, checked the radiator coolant reservoir tank and found little to no coolant in side the reservoir tank. Subsequently as I closed the hood I happened to see a fresh trail of coolant from where I had backed into the parking spot. Looked under the car and the coolant was steadily leaking out from the rear, center left bottom of the engine splash/cover. After getting the vehicle inspected by the repair facility, the vehicle was found to have suffered a coolant pipe failure.

The contact owns a 2005 Porsche Cayenne s. The contact stated that the radiator pipe was fractured, causing anti freeze to leak from the vehicle. The vehicle was towed to the dealer where the original hose lines were replaced with metal lines due to corrosion. The manufacturer was made aware of the failure however, did not offer any assistance. The current mileage was 75,000 and the approximate failure mileage was 74,800.
