I purchased my 2004 Saab 9-5 in 2023. I was under the impression that everything was running and that drivability was proper. When I attempted to drive the automobile it would start, idle 7 minutes and stall. It would not start again for about 35 minutes. I tried to use it, and this behavior continued. Often, in traffic it would stall while I was moving at low speed, and moderate speed: Without warning, it cuts out and won’t start for 40 minutes. I have spent money with my mechanic, over $1,000. I personally bought many parts: MAF sensor, fuel pump relay, fuel filter, and fuel pump. I replaced the Coolant Sensor. After all this the vehicle still stalls 5 minutes after warmup. If it drives to warm up, it stalls and won’t restart for 40 minutes. After I replaced the Crankshaft Position Sensor, (CPS), it has never restarted. I bought 3, one a Bosch branded model, and It has never restarted. Many other drivers complain in forums, like Saab Forums, that they are experiencing the same problems. As you know, stalling at highway speeds can cause death. Clearly the problems with the Saab motorcars, produced, owned, and sold through General Motors, are something that poses a hazard, and should be repaired at GM dealership’s expense. P.S. The vehicle’s immobilizer device has caused my vehicle to not start at all. The key fobs have stopped functioning at all. I replaced the batteries, and they won’t connect to the engine. The vehicle will crank, but no start. Battery runs down, with crank, but no start behavior. Can General Motors either: 1. replace the entire engine, 2. repair the ‘stall, no restart’ situation, 3. moreover repair my seeming to be, ‘anti-theft system, no start’ situation, called DICE/TWICEsystem, 4. achieving an actual fix for these older, but cherished sporting cars?
