NHTSA Complaint #10198919 — 2001 VOLVO V70XC

7/26/07 TRAVELING ON I-77 AND THE CAR RAN GREAT. SUDDENLY, IN SAME MANNER AS CAR DID APPROX 2 YRS AGO ON SAME INTERSTATE RPMS DROPPED, CAR LOST SPEED, NO RESPONSE AT THROTTLE, AND WITHIN A FEW SECONDS WE LOST POWER, BRAKES, STEERING. SINCE THIS SEEMED JUST LIKE 2 YRS AGO (WE REPORTED THIS INCIDENT IN 2005) WE THOUGHT MAYBE THE CAR WILL START IN 10-15M. AFTER 15-20 M OF ATTEMPTS WHERE CAR STARTED & IMMEDIATELY STALLED CAR DID START AND RAN FINE. SINCE 2 YEARS AGO DEALERS WERE UNABLE TO DIAGNOSE & CORRECT WE CONTINUED TO DRIVE THAT EVENING AND AGAIN THE FOLLOWING DAY. THE FOLLOWING DAY THE CAR STALLED AGAIN ON I-? NEAR ATLANTA, BUT THIS TIME IN MORE TRAFFIC WITH DIFFICULTY GETTING CAR TO SIDE SAFELY. AGAIN CAR STARTED LIKE THE EVENING BEFORE. AGAIN-SIMILAR FUEL LEVEL. WE TRAVELED 2 1/2 MORE HOURS ON INTERSTATE. AT DESTINATION AND LOCAL DEALER FOUND NO FAULTS SO NO CORRECTION WAS MADE. AFTER THIS 2ND OCCURRENCE WE FILLED UP MORE OFTEN 1/2 FULL OR MORE. 2 DAYS LATER AND 7 MORE HRS ON ROAD WITHOUT ANY PROBLEM.. AS WE ARRIVE. CHECK ENGINE LIGHT CAME ON. ALTHOUGH CAR RAN FINE WE TOOK CAR TO LOCAL DEALER 1 HOUR AWAY. THEY SAID THEY HAD A CATALYTIC CONVERTER ERROR BUT THEY DIDN'T HAVE ONE IN STOCK. I TOLD THEM I WASN'T SURE THIS WAS THE PROBLEM THAT WAS CAUSING THE STALLING BECAUSE IT STALLED 2X (+1X 2 YEARS AGO) BEFORE THE CHECK ENGINE LIGHT CAME ON. I CALLED MY LOCAL DEALER TO DISCUSS AND HE SAID HE DIDN'T THINK THE CATALYTIC CONVERTER WAS CAUSING THE STALLING. AGAIN, NO DEFINITIVE ANSWERS. AFTER WE LEFT THE DEALER, THE CHECK ENGINE LIGHT WAS OFF AND IT HAS STAYED OFF. A COUPLE OF DAYS LATER WE DROVE THE CAR 9-10 HOURS ON THE INTERSTATE TO GET HOME. AGAIN, I KEPT THE FUEL LEVELS APPROXIMATELY 1/2 TANK AND ABOVE. THE CAR PERFORMED FINE. WE ARE VERY CONCERNED ABOUT THE STALLING. WHEN I CHECK OTHER COMPLAINTS LISTED IT APPEARED THAT SOMEONE ELSE MAY HAVE HAD A SIMILAR ISSUE WITH LOW FUEL STALLING. PLEASE DON'T HESITATE TO CALL TO DISCUSS. *JB
