NHTSA Complaint #10404047 — 2004 VOLVO XC90

I HAVE HAD TWO INCIDENTS IN WHICH THE CAR CYCLES OFF AND ON AFTER APPROXIMATE THREE HOURS OF HIGHWAY DRIVING A FEW TIMES, AND THEN LOSES ALL AUXILIARY POWER, SRS LIGHT COMES ON, BRAKE FAILURE, BUT CAR CONTINUES TO RUN AND BRAKES OPERATE FINE. ON THE SECOND OCCASION, I PULLED OFF THE HIGHWAY, TURNED THE CAR OFF, THEN ON AGAIN, AND THE CAR WORKED FINE FOR A FEW MINUTES, AND DID THIS AGAIN WHEN THE CAR POWERED DOWN, UNTIL I REACHED MY DESTINATION. THE CAR THEN SAT IN A PARKING LOT AND I RETURNED ON THE 250 MILE JOURNEY HOME. I STOPPED EVERY HOUR TO HOUR AND A HALF, AND MADE IT HOME AFTER FIVE HOURS, WITHOUT INCIDENT. THE MECHANIC INITIALLY TOLD ME IT MIGHT BE THE DRIVER INFORMATION MODULE (DIM), WHICH THE PART COST $1200 AND THEN LABOR, BUT IT MAY OR MAY NOT FIX THE PROBLEM. IT IS IN THE SHOP NOW AFTER THE SECOND EPISODE, 3 WEEKS LATER, AND AGAIN THEY SAY IT LOOKS TO BE THE DIM. I AM NOT WILLING TO SPEND THE MONEY ON THIS IF IT WILL NOT FIX THE PROBLEM. I WILL CONTINUE TO DRIVE THE CAR LIKE THIS UNLESS IT BECOMES A SAFETY HAZARD. *TR
