I HAVE BEEN HAVING AN ISSUE WITH MY 2004 VOLVO XC90 WHICH THE DEALERSHIP HAS NOT BEEN ABLE TO CORRECT FOR MY FOURTH VISIT NOW. THE ENTIRE ELECTRICAL SYSTEM SHUTS DOWN WHILE DRIVING ON THE HIGHWAY. THIS HAS BEEN HAPPENING AND EACH TIME I TAKE IT IN, THEY ARE UNABLE TO REPLICATE THE ISSUE AND OF COURSE FIND SOMETHING ELSE TO REPAIR. I HAVE BEEN LUCKY AS NOT HAVE BEEN IN HEAVY TRAFFIC WHEN IT HAPPENS, BUT I COULD IMAGINE IT COULD CAUSE A HORRIBLE ACCIDENT. THE LAST TIME THIS HAPPENED WAS ABOUT 7/18. I WAS DRIVING ABOUT 70MPH ON THE FREEWAY AND THE CAR MADE A 'THUMP' AND ALL THE LIGHTS AND GAUGES TURNED OFF MOMENTARILY AND STARTED BACK UP AGAIN. I SLOWED DOWN TO ABOUT 60MPH AND MOVED TO THE RIGHT SIDE AND THE EXACT SAME THING HAPPENED AGAIN ABOUT 5 MIN LATER. LUCKILY I WAS CLOSE TO THE EXIT WHERE MY MECHANIC SHOP WAS SO I SLOWED DOWN TO EXIT. ALL OF THE LIGHTS ON THE INSTRUMENT PANEL TURNED OFF, AS WELL AS THE AIRCONDITIONING (115 DAY IN PHX) AND A WARNING LIGHT FLASHED SAYING I HAD A BREAK FAILURE. I WAS ABLE TO LIMP TO THE MECHANICS AND LEFT THE CAR RUNNING SO THEY COULD SEE THE ENGINE WAS ON, BUT NOTHING ELSE. THEY DID NOT HAVE THE EQUIPMENT TO CHECK THE 'CODE' ON A VOLVO. THEY WERE ABLE TO RE-SET IT BY DISCONNECTING THE BATTERY, AND THE LIGHTS WORKED AGAIN. AS I PULLED OUT OF THE MECHANICS, THE CAR THUMPED AGAIN AND I ONCE AGAIN LOST ALL POWER. I LIMPED THE CAR HOME WITH PLANS TO DRIVE IT EARLY IN THE MORNING BEFORE IT GOT TOO HOT, TO THE VOLVO DEALERSHIP. IN THE MORNING, THE CAR WOULD NOT START AT ALL. I CALLED A TOW TRUCK AND HAD IT BROUGHT OVER. THE VOLVO DEALERSHIP ONCE AGAIN COULD FIND NOTHING WRONG, BUT FOUND SOMETHING TO FIX AND CHARGE ME FOR, THE IMPULSE SENSOR ($250). I FINALLY GOT THE CAR BACK ON JULY 29TH, 10 DAYS LATER. THIS ISSUE HAS BEEN EXPERIENCED BY MANY 04/05 XC90 OWNERS AS DESCRIBED IN THIS FORUM,HTTP://WWW.VOLVO-FORUMS.COM/T23397-XC90-ELECTRICALENGINE-POWER-FAILURE.HTM. I ASK THAT YOU HAVE VOLVO FIX THIS ISSUE, BEFORE SOMEONE DIES. *TR
