Have a 2004 XC90 T-6 that recently gave me a thud in the drive side dashboard, then all the instruments went out, signals died, windows would not open, AC died and the transmission was stuck in gear - would not shift as the engine rpm's increased! Luckiliy I was on a side street. Turned it off, let it sit and it started ok but all the warning lights on the dash were on. Took it for repair and there were so many codes they could not tell what was wrong. They cleared the codes and it ran fine for 2 weeks - then happened again. Same process, cleared codes and again 4 weeks later, but this time with my wife driving!

Dealer has no idea. Volvo of America has no idea! Yet the car is unreliable and should it do this in highway traffic we could all be hurt!

Does anyone have the solution?

I have heard that the CEM, DIM, or wiring harness tied with the seats might be the issue, but the dealer and Volvo plead ignorant on all counts. CEM is quoted as $1300, DIM is $1300 and check the wiring = $2000. Guess this "luxury" vehicle carries a high price but NO RELIABILITY or Volvo support!

I have also created a google doc shared link in case you would list your name so we can get a list going to share with Volvo to get some action, or find an attorney to help. The link is:https://spreadsheets.google.com/ccc?...fdkJocUE&hl=en

Thanks for any help,
