2008 Volvo S60

I WAS DRIVING ON THE FREEWAY IN SOUTHERN CALIFORNIA HEADING TO SAN DIEGO DURING EVENING RUSH HOUR TRAFFIC. THE TRAFFIC HAD COME TO A COMPLETE STOP AND AS TRAFFIC WAS STARTING AGAIN AS I PRESSED THE ACCELERATOR THE CAR ENGINE BEGAN TO SPUTTER. THERE WERE NO DASHBOARD WARNING LIGHTS OR INDICATORS TO GIVE US ANY INFORMATION ON WHAT WAS GOING ON WITH THE CAR. I ONLY KNEW THAT I HAD NO ENGINE POWER. THE GASOLINE GAUGE SHOWED THAT I HAD ABOUT HALF A TANK OF GAS LEFT. WE TRIED TO RESTART THE ENGINE A COUPLE OF TIME. THE ENGINE WOULD SPUTTER AND THEN DIE. FORTUNATELY, I WAS IN THE SLOWER RIGHT HAND LANE AND WAS ABLE TO PULL SAFELY OFF TO THE SHOULDER. IF I HAD BEEN THE FASTER FREEWAY LANES, WITH THIS SUDDEN LOSS OF ENGINE POWER, WE WOULD NOT HAVE BEEN SAFE AND THE RESULTS MAY HAVE BEEN VERY TRAGIC! WE WERE TOWED TO A VOLVO DEALER IN CARLSBAD, CALIFORNIA. THERE THE DEALER FOUND THAT THE CAR HAS A FAULTY FUEL PUMP AND SENSORS. WITH THE FAULTY SENSOR, WHILE THE GASOLINE TANK APPEARED ON THE DISPLAY GAUGE ON THE INSTRUMENT PANEL TO BE HALF FULL, THE TANK WAS ACTUALLY ALMOST EMPTY. CURRENTLY, (AS OF APRIL 6,2015) THE CAR IS STILL WITH THE VOLVO DEALER WAITING FOR THE PART TO ARRIVE FROM THE EAST COAST. MY CONCERN IS THAT THIS IS A RELATIVELY NEW CAR - 2008 MODEL WITH LOW MILEAGE. I AM CONCERNED THAT THE FUEL PUMP AND THE SENSORS ARE DEFECTIVE PARTS FOR THIS MODEL CAR. I APPRECIATE ANY ASSISTANCE OR ADVICE YOU CAN PROVIDE ME ON THIS ISSUE. *TR
