MY 2001 VOLVO V70 SPONTANEOUSLY LOST POWER AND DIED. I WAS STRANDED FAR FROM HOME WITH MY DAUGHTER ON A FRIDAY NIGHT. AFTER SUPPOSEDLY BEING REPAIRED AT THE DEALERSHIP, SEVERAL MONTHS LATER ON A ROAD TRIP, AGAIN FAR FROM HOME, MY CAR ALL OF A SUDDEN STARTED COUGHING AND LOSING POWER, ON THE HIGHWAY AT HIGHWAY SPEED, PUTTING ME AND MY PASSENGERS AT RISK.

INITIALLY, I TOOK MY 2001 VOLVO V70 STATION WAGON TO THE DEALER BECAUSE THE CRUISE CONTROL FUNCTION WAS NOT WORKING AND THE "CHECK ENGINE" LIGHT CAME ON. THEY RAN A DIAGNOSTIC COMPUTER CHECK AND TOLD ME THAT EVERYTHING CAME BACK FINE -EVEN THOUGH IT WAS OBVIOUS THAT THE CRUISE CONTROL WAS NOT WORKING WHEN WE DROVE IT AROUND THE LOT. THEY SAID THAT IF THE COMPUTER DID NOT DETECT AN ERROR THEY WERE NOT ABLE TO FIX ANYTHING, ALTHOUGH THEY SUSPECTED THAT THE ELECTRONIC THROTTLE CONTROL MIGHT BE CAUSING THE PROBLEM. THEY RESET THE COMPUTER SO THAT THE "CHECK ENGINE" LIGHT WENT OFF. A MONTH LATER, I WAS PULLING OUT INTO TRAFFIC FROM MY DRIVEWAY WITH MY THREE-YEAR OLD IN THE BACK SEAT AND LOST ALL POWER. THE MAX SPEED I COULD GO WAS ABOUT 10 MPH. FORTUNATELY, I WAS ABLE TO PULL OFF TO THE SIDE OF THE ROAD. IT IS A VERY BUSY UNCONTROLLED ACCESS - I WAS FORTUNATE THAT THERE WASN'T MORE TRAFFIC AS AN ACCIDENT WOULD HAVE OCCURRED. THERE WAS NO WARNING LIGHTS OR INDICATION THAT THIS WAS GOING TO OCCUR - IT JUST STOPPED. I HAD THE CAR TOWED TO THE VOLVO DEALER WHO DIAGNOSED A MALFUNCTIONING ELECTRONIC THROTTLE MODULE. THE CAR HAD 72,000 MILES ON IT. I EXPRESSED MY DISAPPOINTMENT THAT A CAR WITH A REPUTATION FOR SAFETY WOULD FAIL IN SUCH A WAY THAT COULD CAUSE A TERRIBLE ACCIDENT. I ALSO LODGED A COMPLAINT WITH VOLVO CUSTOMER SERVICE. RECENTLY, I HEARD ABOUT THE INVESTIGATION ON THIS SAME ISSUE. I WAS DIRECTED TO YOUR WEBSITE WHEN I SEARCHED FOR ADDITIONAL INFORMATION ON THE INTERNET. *JB

DT: THE CONSUMER WAS HAVING PROBLEMS WITH VOLVO 2001 V-70 CROSS COUNTRY WAGON. THE VEHICLE WAS STALLING AT RANDOM SPEEDS STARTING IN MID-AUGUST OF 2004. CONSUMER TOOK THE VEHICLE TO A REPAIR SHOP, AND THE MECHANIC SUSPECTED THE THROTTLE WAS THE ISSUE. THE PROBLEM WAS RANDOM AND IT WOULD NOT DO THIS FOR SEVERAL DAYS. THE VEHICLE STALLED ON THE HIGHWAY WHILE THE CONSUMER WAS MERGING INTO TRAFFIC. THE VEHICLE WOULD START AFTER CONSUMER LET THE CAR SIT FOR A FEW MINUTES. LATER THAT DAY THE CAR STALLED AGAIN. CONSUMER HAD TO HAVE THE CAR TOWED TO A DEALERSHIP FOR REPAIRS. THIS TIME THE CAR DID NOT START. THE DEALER REPLACED THE THROTTLE MODULE, LOADED SOFTWARE; THROTTLE BODY, CABLE TIE AND ETM RELOADED. THE CAR WAS RUNNING OKAY AT TIMES, BUT THE ENGINE WAS RACING VERY HIGH FOR SECONDS AND THEN RETURNS BACK TO THE NORMAL RATE. THE MOTORWAS REVVING AND THE TACHOMETER WAS REGISTERING HIGH FOR A MOMENT. CONSUMER CONSIDERED RETURNING THE VEHICLE BECAUSE OF THE PROBLEMS. THE TOTAL COST ON REPAIRS HAS BEEN OVER $800.00. NHTSA INVESTIGATION, PE05041. *AK *JB
