2005 Xc90 v8-many problems with check engine light coming on and car losing power. Lost power on interstate-car would lose power and speed-needed tow-happened twice. Current issue check engine light came on followed by all lights coming on stating brake failure, power overload, limp mode and brake failure. Dealer replaced alternator at cost of $1006. 10 days later check engine light and anti skid light came on followed by brake failure light. Car lost headlights and windshield wipers-9 pm and sleeting. Dealer now says need to replace cem and battery at a cost of $3,000 due to water in cem. It was raining or sleeting both times the check engine light came on. Volvo redesigned the cover to prevent water intrusion but needs to issue recall. Very dangerous- ticking time bomb. Someone will have an accident on rainy night on interstate. Please consider requiring recall-owners of this vehicle are spending thousands of dollars due to Volvo Xc90 v8 design flaws. How can Volvo be allowed to sell vehicles that should not be driven outside/or in the rain.
