Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Driving in a high performance driving event on a hot day going around a fast right hand turn and felt the car being a little loose then noticed the on board computer flashing low coolant. I slowed down and pulled in to a safe place to check the motor and saw a coolant j shaped press fitting completely popped out and dumping mass amounts of slippery coolant on the engine and rear tires. I popped the fitting back in and safety wired it so hopefully it will not come back out. Replaced coolant fluid with new and burped the system.”
NHTSA complaint #10379946, filed 2011-02, 39,000 miles“Porsche gt1 engine press fit coolant coupling failure. High pressure coolant coupler fails causing rapid loss of all coolant. This is not only a toxic hazard, but a safety concern on the road. Further, loss of coolant jeopardizes engine life. The gt1 engine has 8 press fit couplings. So far, 2 different couplings have failed on my car. 1 on the heat exchanger, and 1 on the steering pump housing.”
NHTSA complaint #10379589, filed 2011-01, 23,000 miles“Porsche gt1 engine press fit coupling for coolant lines. When coupling fails, there is rapid coolant loss which is a toxic hazard as well as potentially dangerous to traffic. Also, without coolant the engine is in jeopardy of overheating.”
NHTSA complaint #10379588, filed 2011-01, 35,000 miles“Pressed fittings for the cooling system failed dumping coolant on the rear tires causing the car to crash. The replacement part failed the same way three weeks later.”
