“I had pro-active repairs performed on my 2004 Porsche gt3 coolant system due to known issue of coolant pipes separating from the engine. I had the repair performed because I was afraid of losing control of my vehicle (it is my daily driver) or causing a crash behind me. The repairs cost me $3900 + ca state tax (7.75%) for a total of: $4200+.”
NHTSA complaint #10514295, filed 2013-05, 18,000 miles“The coolant lines on this car have well known and documented failure problems. I am very concerned for my safety and the safety of my passengers and as such am going to have the repairs completed as a precautionary measure. With the failure rate of the coolant fittings on these cars, and the usually catastrophic results I do not feel safe driving this vehicle. I'm going to spend my own money to correct a problem that should have been fixed by Porsche.”
NHTSA complaint #10513371, filed 2013-05, 24,148 miles“I purchased my 2004 Porsche gt3 in may of 2009. It had just under 20,000 miles on it. In august, 2010, I was driving on track at texas motor speedway and one of the coolant fittings came loose from the engine. The epoxy that holds the press-fit coupler to one of the heat exchangers had lost its ability to retain the fitting and came disconnected. All of the engine coolant was lost in a single instance. [catastrophic coolant loss]. I had that fitting replaced by the Porsche dealer in dallas under aftermarket warranty. …”
NHTSA complaint #10519858, filed 2013-06, 20,000 miles“I bought this car brand new from Porsche and although it only has around 14,000 miles on it, I feel I must limit use of the car until it gets the glued coolant lines repaired. I have not had a failure yet but the risks of waiting until that happens are high and could easily go beyond the financial aspects and result in physical harm to myself, a passenger, or other motorists. The problem of catastrophic coolant line failure is well known with this model due to the use of glue rather than mechanical or welded connections. …”
NHTSA complaint #10511702, filed 2013-05, 14,000 miles“I was driving at miller motorsports in tooele utah in drivers education event when my engine temperature gauge started to increase from 180 degrees up past 200 degrees. As the temperature gauge went to 250 degrees, a coolant failure light came on. I pulled off the track and shut down the car within 2 minutes of the failure light and I had to be towed off the miller motorsports track. I had lost all of my coolant from the car. The next morning (sunday) I took a rental car back to miller motorsports along with 9 gallons of distilled water. …”
