I have had my 2003 XC90 for 20,000 plus miles. Other than 'normal service' and a few recalls here and there I have been completely happy. About 4 weeks ago when I went to start my car, the engine will crank but not turn on - in the message box I get "Anti-Skid" service needed, the check service light comes on and after 3,4 hours the car will finally start.We have 'upgraded the software' that was suppose to fix it -3 weeks later I continue to experience the same issue over and over.

Help! and Thank you.
