In May, my wife experienced a complete loss of the center LCD display..no Radio, Nav, My Car and the BLIS stopped working. It was intermittent. We took it in and the dealer said they would re-load the software (SW) in the ICM Control Unit 36001980-6, which by Volvo poilicy they could not replace until having tried reloading the SW once. I was skeptical that SW could could cause such an intermittent fault, but it did work OK until a week ago, when the problem recurred. We took it back when they had the new part, but it would not accept SW, so they had to order yet another replacement, which did work. This is not a case where you can bring it in and wait while they plug in the new part...apparently it takes hours just to load the SW. But they gave us decent loaners in both cases. The part alone costs ~$900. It is working properly so far, but after this and the CANBUS failure reported here previously, we are thinking extended warranty. Thoughts?
