"On Wednesday (02/05/2014), at 11 clock, a Porsche has caught on fire on the Wilerstrasse. Firefighters were able to extinguish the fire. The car suffered a total loss in the amount of CHF 200'000. A Porsche GT3 drove on the A1 highway towards St.Gallen. When the driver perceived strange noises from the engine area, he left the highway. On the Wilerstrasse the driver stopped the car. He saw leaking oil and smoke is in the rear engine. A short time later the Porsche caught fire. The fire was extinguished by the fire department. The cause of the fire will be investigated by the Forensic Science Service of the Canton of St. Gallen police."
In the interest of safety 991 GT3 owners should park their cars for now. Apparently five vehicles have suffered this fate. Here is the perspective of the president of an Italian Porsche club from the Rennteam Forums who saw a club members car also go up in flames:
"I am the administrator of Porsche Club Campania, an Italian Porsche club.A member of our Club last Saturday was near Avellino, in the south of Italy, his gt3 was really new, just 60kms. First the warning LOW OIL PRESSURE in the display and after few seconds his GT3 was burning. The gt3 DESTROYED is now at the PORSCHE CENTER NAPOLI and this morning an engineer from Stuttgart came here to see the car. It is the 5th gt3 in Europe that burned with the same problem. It seems that Porsche already know where is the problem but I don't know if the dealer will be able to fix the problem. I will keep you updated."
Porsche has yet to officially comment on the issue and they are more than likely aware as apparently deliveries of GT3's are halted until further notice.
