Software Problems of Volvo S40

The starter control unit (scu) on my 2005 Volvo S40 has ceased to function twice in the 5 years that I've had it (50,000 miles). Essentially, this means that the scu does not read the key (the car tells me I have a "key error"), and therefore the car shuts down completely and does not turn on (the steering locks, the car does not start, it is unusable). The first time it happened, it was under warranty, therefore it was fixed free of charge. It happened again last month, was diagnosed by the bill pearce (reno, nv) dealership as the same issue, and I was given a 50% discount on the repair. It is an issue that apparently many other 2005 Volvo S40 owners have had (learned this through a simple internet search), but it is not recognized as an issue with Volvo and is not a recall item. It is a software problem, not a wear and tear item or something that I can maintain and keep from happening. It should not be something that I have to pay several hundred dollars to fix. There is no warning when this is about to happen. The car works on minute and then doesn't the next. I have no way of knowing when it is going to happen, and was stuck 200 miles from a dealership the last time it happened. It can supposedly be fixed only by the dealership because it's needs the proper software download. Please look into this issue. I have a car that I can no longer trust and the dealerships don't recognize it as a legitimate issue. I have all the documentation to provide if necessary.

Dashboard went crazy, fading in and out. All panels were unreadable, speedometer, radio, temperature gauge. Car accelerated on its own, without my foot on the pedal. Cd was shot into the backseat landing in my child safety seat. All of this occurred while driving on the highway. In all 3 instances the message indicator stated to not drive the car. I had the car towed to 2 different dealers. The first time they said it was the software and reinstalled. The second time, they replaced the alternator and the car was in the shop for over a week, the third time, the replace the cem module and radio. The the fourth time the car wouldn't read the key and had to be towed and they replaced the steering module. This car has been in the shop 3 times in less than 6 months for 3 electrical related issues the car only has 42,000 mile.

I was driving home at night when all of the gauges in my car went out completely. I had no speedometer, no gas reading, no engine heat meter, the message center was out, no turn signals. This is a 2 year old vehicle that was purchased brand new from Volvo in 2004. I had to drive home 60 miles on an extreme;y dark road with no safety gauges- I couldn't call for roadside as I was alone and am a woman- I wasn't going to stop on the side of the road to wait for roadside. I was told by Volvo that it was the ddm module and the wiring harness- my electrical /computer system went bad. How is that possible in a brand new car? furthermore, I was 1,000 miles over the manufacturer's warranty of 50,000 miles- thus Volvo charged me $1,645. 00. Within in minutes of driving the car after it was repaired- the service engine light came on. I was told that my software had to be upgraded and my throttle cleaned? I believe that the electrical/computer systems in these cars are no good.
