What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Coolant hose coupling came lose while driving the vehicle at speed, resulting in loss of all engine coolant. Coolant spilled resulted in temporary reduction of vehicle traction, fortunately without incident. Engine damage due to possible overheating is under investigation.
Resulted in rapid coolant loss. Car had to be towed/hauled approx 140 miles to repair facility near my home. I have not yet seen the bill for this service. I am having all coolant fittings welded to prevent this from happening to any of the other lines. Work is not yet complete but the estimated bill is $3500+.
I was driving my car on I-79(3 lane highway) at 70 mph when I noticed a large cloud of smoke/steam from the rear of my car. I then noticed other cars pulling off to the side to get away from all the coolant spraying from my car. I pulled off to the side of the road and called for a tow truck.
Driving a 2007 porsche gt3 when a hose fitting came loose from the engine block causing a catastrophic loss of coolant from the engine. The failure can occur multiple times I have been told by other owners of 996 and 997 model porsche 911 model variants.
Vehicle had complete loss of control due to a cooling system fitting coming unglued from the engine block. The coolant fitting is press fitted into place using an adhesive that failed. The entire contents of the cooling system released onto the rear tires causing a loss of control.
Coolant fitting adhesive failed, spraying coolant on rear tires, which caused the vehicle to lose control. Fitting was replaced under warranty with the same problematic adhesive.
