Gearbox malfunction has occurred twice leaving me stranded on the highway and the car will not go over 5 mph. Extremely dangerous as this occurs unexpectedly in traffic. Dealer fixed both times, but transmission still slipped and I feared driving it. The dealer took it in again and had their transmission specialist drive and inspect it. The dealer says that there is a known problem with the 2003 9. 3 Saabs with contamination of the transmission fluid causing the transmission to fail. The transmission fluid is cooled within a section of the radiator. The block that separates the coolant from the transmission fluid is bad and causes the coolant to leak into the transmission fluid. I was scheduled for a new transmission, a new radiator (under warranty), but the car failed a 3rd time when I was trying to drive to the dealer for service. They had another 9. 3 scheduled at the same time for the same problem. Additionally, they are telling me that I need front and back brakes - not under warranty - will cost me $1,000. This is the most serious of the problems I have had with this car, but have had it in the shop 16 days for numerous problems with headlights, on star, sid, locks, door issue, window issue, oil leaks. I am very concerned that a car with this safety rating can have this many problems and especially the extremely dangerous transmission issues that leave you stranded in traffic.
