What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
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.
Failure of factory glued in coolant fitting caused an instant dump of coolant onto the rear tires of the car causing loss of control and a spin. This is a well documented problem in all porsche gt3's and porsche turbo's and porsche refuses to identify the design flaw of having these fittings glued together.
While driving the car on track, a coolant fitting broke loose and dumped all the antifreeze down onto the track surface. A vehicle on track behind me ran over the antifreeze, lost control and skidded off the track. The driver of the other car wasn't injured and there didn't appear to be much damage to his car, except perhaps some scuffing of the paint on his front bumper. The fitting that came loose is one of 8 fittings that porsche glued into place when they originally built the engine of my 04 gt3.
Previous owner stated that coolant lines disconnected due to failure of the fittings. Coolant was spilled all over the road behind him. Another driver barely missed the coolant but there could have been a major accident. Porsche fixed the problem under warranty, but the fittings were not welded as the fix recommends, merely re-glued. I'm afraid this will happen again.
On very hot day, over 100 degrees f, after having just exited a freeway onto a city street, while accelerating from red light, a glued-in water coolant pipe/tube popped out from its cast housing, causing catastrophic loss of all cooling fluids which spilled onto the roadway, immediate increase in engine temperature from 185 to over 260 degrees f, and loss of power. Car needed to be towed to repair shop.
