One problem related to car stall has been reported for the 2004 Porsche 911 Gt3. The most recently reported issues are listed below.
While driving at a drivers education event at watkins glen race track, a coolant fitting came apart and out of its housing releasing about 3-4 gallons of coolant onto the track. Luckily no accident occurred. Since the car was still under warrenty Porsche agreed to cover the failure under good will and a new housing (same design) was installed by the local Porsche dealer. However, in October, 2011 while driving at another drivers education event, the same fitting failed. This time 3 cars following me slid off the track due to the coolant with one crashing into another. One car was totaled and the other seriously damaged.
