Car Will Not Start problems of the 2005 Volvo XC90

- purchased used 2005 Volvo Xc90 in spring of 2010 -- during the next year experienced very intermitten electrical issues. Examples are locks not working, blinker, radio. These issues literally only happened a couple times. - in April 2011 had biyearly safety and emissions done at local dealership (non Volvo) and it did not pass emissions - next day took my Volvo Xc90 to weiss Volvo and it passed emissions (without me knowing they cleared errors on the car to get it to pass - this must be the reason in europe that dealerships can't inspect their own make of cars) - on July 17 2011 I was driving down the highway with my 1 year old in the back seat. Radio went out. A few minutes later almost everything in the car shut down except for the engine. Lost a/c (it was 110 that day), lost power steering, braking was intermitten, no blinkers, no headlights, no lights in interior, while I was at full speed on the highway. I am not sure if engine was intermitten or not because I got off as soon as I could. - I was very close to weiss Volvo so dropped it off there again on the date of the total failure. - called Volvo customer care on July 18 2011 to file complaint. - weiss Volvo called back and told us car wouldn't start. Called back later in the day and said they saw that everything went out and car was full of codes. - weiss sent in an estimate for $1500 to replace cem. - I asked weiss to perform an emissions test (by mo law manufacturer's cars must pass emissions test up to 80k miles and my car had 61k) - I researched cem and found very similar stories to mine and brought this up to Volvo na. - Volvo na told weiss Volvo to "reset" my car (again without my permission). The car then was functional after reset. - weiss then "tested" my car for almost 3 weeks to figure out the design flaw for a total of 451 miles. The mechanic told me it was the cem but Volvo na said it was various other reasons and wouldn't replace it. - car still broke. . . . Reached limit.
