Side/window Air Bag Problems of Volvo XC90

At about 60,000 miles while the vehicle, a 2004 Volvo xc 90 t6 was in operation at 55 mph the power to the dash and all accessories went dead. The horn, the blinkers, the speedometer (radio, power windows etc. ) all failed to work even as the car was in operation and was being driven on the highway. Later upon restart there was an error code in the dash, in the icm I believe they call it (infotainment control module), saying urgent srs (supplemental support system- aka side airbags) service urgent ?or something to that effect. The dealer used their proprietary reader to decipher the error codes and we were told that the dim, or driver information module for the srs system had gone bad, it had a short. They said if we did not replace it they said that the short could override communication of the other modules and electronics on that same circuit and we might lose other controls including possibly an unexpected engine shutdown or other operational abilities. $ 1532. 00 later, and less than two days after we had the SUV repaired, we had a repeat of the complete dash power failure. This time we were too worried to turn the car off and instead drove directly to the dealer without a speedometer, horn, gas gauge or turn signals. We checked and the wipers remained operational. Upon restart at the dealership the same error message appears- srs service urgent. But this time the dealer reads the diagnostic error codes and tells us that it is likely a cem, or central electronic module- (about $1200. 00 + tax) but they add it might be the dem or differential electronic module. It seems ludicrous that necessary electronic controls would not have protection from cross failures, and that a bad dim or cem would place the operators and passengers at risk by knocking out other controls. Of course I am wondering how to determine if the dealer is right this time and even more concerned about experiencing another blackout.

2004 Volvo Xc90. Consumer states problem with transmission the consumer stated the vehicle was jumping into gear or lunging when he applied the accelerator pedal. The consumer stated the original transmission was replaced at 53,000 miles in 2008. The dealer performed a diagnostic check and determined that the front axle had lost a plug and that the transmission had become contaminated and that was the cause of the jumping in the transmission. The repair of the front axle and transmission flush was approved at Volvo's cost. However, diagnostics also revealed the passenger side air bag was defective and needed to be replaced.
