WE PURCHASED A 2001 VOLVO V70 2.4T WAGON 12-16-01 FROM THE DEALER, WHO HAD USED IT AS A LOANER VEHICLE. THIS COMPLAINT IS REGARDING THE THROTTLE CONTROL. FOR ABOUT A MONTH IT WOULD FEEL AS IF A PLUG WAS BAD OR A FUEL LINE CLOGGED WHEN DRIVING AT A STEADY SPEED. IT WASN'T AT FIRST NOTICEABLE DURING ACCELERATION. THEN A "REDUCED PERFORMANCE" MESSAGE CAME ON THE DASH. FINALLY, ON 8-20-05, THE CAR STALLED ON THE WAY TO THE DEALER IN RENO TO GET IT REPAIRED. FORTUNATELY, WE WERE IN THE RIGHT LANE AND MANAGED TO PULL OFF THE ROAD OUT OF TRAFFIC. JUST A MATTER OF TIMING AND THIS PROBLEM COULD WELL HAVE BEEN DEADLY. IT RESTARTED AND WE MADE IT INTO THE DEALER. THE THROTTLE BODY WAS REPLACED AND THE PVC SYSTEM CLEANED, AS THE SERVICE MANAGER STATED THE PROBLEM CAUSED IT TO NEED CLEANING. THE TOTAL BILL WAS $1,336.49. I FEEL VOLVO HAS A SERIOUS PROBLEM HERE, AND JUDGING BY THE NUMBER OF COMPLAINTS, WHICH MUST BE ONLY A FRACTION OF THE NUMBER OF INCIDENTS, IT IS ONLY A MATTER OF TIME BEFORE IT CAUSES DEATHS ON THE HIGHWAY IF IT HASN'T ALREADY. *JB

I HAD BEEN EXPERIENCING A HESITATION FOR APPX SIX MONTHS, JUST WONDERING WHEN THE CAR WOULD FINALLY FAIL AND WHERE. I DROVE THE CAR HOME ON LIMP MODE TWICE. I'D TAKEN THE CAR TO THE DEALERSHIP ON 4 SEPARATE OCCASIONS TO FIGURE OUT THE PROBLEM. EACH TIME THEY COULD NOT FIGURE OUT THE PROBLEM AND CHARGED ME TO LOOK AT THE CAR.

THEY COULD NOT ADJUST THE TRANSMISSION. CURFRENTLY, THEY TOLD HIM THAT IT WA STHE THROTTLE BODY. TO REPLACE IT WOULD COST CONSUMER $800.00. HE ENDED UP PAYING $250.00 FOR THROTTLE BODY REPLACEMENT.

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

ON WEDNESDAY AUGUST 24,2005 I WAS DRIVING ON THE INDIANA TOLL ROAD TOWARD CHICAGO WHEN MY 2001 VOLVO V70 WHICH HAS LESS THAN 40,000 MILES ON IT, STOPPED RESPONDING TO MY FOOT ON THE GAS PEDAL. A MESSAGE LIGHT THAT SAID "PERFORMANCE REDUCED" CAME ON AND I COASTED WITHOUT ANY CONTROL OVER THE SPEED OR POWER OF THE CAR. I WAS FORTUNATE TO BE CLOSE TO A TOLL BOOTH AND WAS ABLE TO PULL OVER TO THE SAFETY LANE PAST THE BOOTH. I WAS FORTUNATE TO BE IN A SAFE PLACE ESPECIALLY AS I HAD MY 7 YEAR OLD SON AND DOG IN THE BACK OF THE CAR. I TURNED OFF THE CAR AND SAT FOR ABOUT 10 MINUTES TRYING TO FIGURE OUT WHAT TO DO (EVEN THOUGH THE CAR HAS ONLY 39500 MILES ON IT, WHICH IS NO LONGER UNDER WARRANTY). I STARTED THE CAR 10 MINUTES AFTER THIS EVENT, IT STARTED UP FINE, AND THERE WERE NO WARNING LIGHTS OR MESSAGES. I DECIDED WE WOULD BE SAFER GETTING OFF THE TOLL ROAD EVEN THOUGH I WAS TAKING A RISK THAT THIS COULD HAPPEN AGAIN. I DROVE THE REMAINING 15 MILES HOME WITHOUT A PROBLEM (NO MESSAGES OR WARNINGS). I WAS ABLE TO BRING THE CAR TO A MECHANIC WHO IS AN AUTHORIZED VOLVO DEALER, HE CALLED ME ONE HOUR LATER AND TOLD ME THE PROBLEM WAS THE THROTTLE MODULE AND HE WOULD WORK TO FIX IT. BECAUSE I DIDN'T THINK SOMETHING LIKE THIS SHOULD HAPPEN TO A 4 YEAR OLD CAR WITH VERY LITTLE MILEAGE, I DECIDED TO CHECK THE INTERNET TO SEE IF THERE WAS ANY NEWS REGARDING VOLVO. I GOGGLED VOLVO THROTTLE AND FOUND TWO REFERENCES TO A NEWLY OPENED INVESTIGATION THAT DESCRIBED A SCENARIO VERY SIMILAR TO WHAT WE EXPERIENCED. I DECIDED TO CHECK THIS WEB SITE TO LEARN MORE. AS OF TODAY, AUGUST 29, 2005, MY CAR IS STILL NOT REPAIRED. THE MECHANIC IS WORKING WITH VOLVO. THE MECHANIC HAS BEEN TOLD SINCE AUG. 25, THAT THE VOLVO COMPUTER, WHICH IS NECESSARY FOR THE THROTTLE REPLACEMENT DOWNLOAD, HAS BEEN DOWN FOR 4 BUSINESS DAYS. IN ADDITION TO BEING PUT IN A DANGEROUS SITUATION ON THE TOLL ROAD WITH MY YOUNG SON, MY CAR WILL COST CLOSE TO $1000 TO FIX, AND I HAVE NOT HAD USE OF MY CAR FOR 5 DAYS!
