While driving home from work in december 2015, on a local road near my home, the engine began emitting a large steam cloud behind the vehicle and the coolant level light appeared. I pulled over and there was a major coolant leak behind the car. I had the car taken to a shop, and they identified the issues as one of the coolant pipes had separated from the engine and dumped all of the coolant on the road. In the attached image you can see the separated coolant pipe from the engine towards the back of the picture. Given the cost of repair, I had to wait until summer of 2016 to have the repair completed.

I was driving my vehicle down the highway while accelerating when I felt the car squirm and noticed a large cloud of smoke billowing from the rear of the vehicle. I pulled over and identified the issue as a catastrophic coolant leak from the engine area (rear) of the vehicle. I had the vehicle transported home and then to a repair shop where they identified the problem as a coolant line that became separated from the engine block. It was explained to me that porsche, from the factory, used an adhesive like material to mate the connectors of the coolant lines and engine and after usage they will come apart causing coolant to be hemorrhaged onto the engine and potentially wheels/tires causing for very dangerous road conditions. During the incident I almost lost control of my vehicle due to the coolant contacting the tires which would not have otherwise happened had porsche not manufactured their vehicles in the aforementioned way. I as well as others on the road were put in a very dangerous situation because of this manufacturing issue.

I noticed a small coolant leak from the rear drivers side of the engine. This leak became more prominent over the next several days. I took my car to the shop to have it evaluated and it was determined that 4 out of 6 coolant fittings were leaking. The design from porsche has the coolant hoses affixed using an epoxy. After many heat cycles and time, this epoxy fails and coolant leaks from the engine. The engine must be removed to properly fix the problem and it is going to cost me approximately $6,000. This is a known issue for this car and is something porsche should take care of.

I noticed a small pool of coolant underneath the engine compartment. Upon further research I believe the car is suffering from a common problem of the cooling fixtures that are glued onto the motor rather than welded. Amazing that a car this expensive would have such a poorly thought out problem like this. I will take the car to the dealer for estimates but I understand that an engine removal is required and all coolant fixtures need to be welded. This is a rather expensive repair for what appears to be a very flawed design. I have driven the car only a few times since the first incident and notice a pool of coolant every time the car is parked. I will not drive the car until fixed as I understand the coolant leak can be a hazard to be me while driving as well as the cars behind me if I suffer a catastrophic coolant loss.

Coolant leak caused by fitting failure. Repair requires engine removal to replace plastic fittings.

Summary: failure of coolant hoses during normal operation of vehicle, resulting in immediate flushing of all coolant onto road surface and into engine bay. Immediate engine shutdown required to prevent further damage. Observed risks include: panic situation to operator and passengers of vehicle; catastrophic engine failure due to overheating and consequent accident threat; loss of traction to vehicle and subsequent traffic due to high volume of coolant on road surface; vapor trail limiting visibility of subsequent traffic; roadside accident hazard affecting vehicle and subsequent traffic. Details: saturday, july 27, 2013, ~7:15pm et, nassau county ny - westbound on state route 24 - hempstead turnpike. Driving at approximately 45mph in 3rd gear, vehicle operator noticed a thick cloud of vapor emanating from the rear of the vehicle, over the engine compartment. Operator brought vehicle to a halt in the middle of the road, whereupon the odor of burning coolant was detected. Having been familiarized with reports of like vehicles being afflicted with these symptoms, operator immediately placed vehicle into reverse and backed vehicle off of route 24 and onto a side street, and turned off vehicle by removing the key. Operator observed the outside temperature to be approximately 75 degrees fahrenheit, and the vehicle's reported (remaining) coolant temperature to be approximately 190 degrees centigrade at the time of the incident. All other vehicle systems were functioning properly at the time of the incident. Vehicle has been regularly serviced and its engine, intake, and cooling systems are unmodified, factory specification. Operator has photographic evidence of the event and will provide to the federal safety agency and related parties upon lawful request.

My mechanic informed me that porsche used an inferior and mechanically poor design for the engine coolant lines. They are glued together in a place where they get hot. After several heat cycles, they will fail. All cars with this engine design will have this failure over time. If the coolant lines fail while the car is moving, the slick coolant can get on the tires and cause an accident. Also, the engine can overheat with a replacement cost of over $20,000. Porsche is aware of this, as they have uses a superior threaded design on their race cars with this engine. I have been advised that this will take thousands of dollars to fix, and the car will be out of service for weeks.
