SINCE PURCHASING THIS VEHICLE IT HAS BEEN IN FOR THE SAME PROBLEM 12 TIMES. EACH TIME THE BILL HAS BEEN BETWEEN $900.00 AND $1500.00 THIS IS THE SAME PROBLEM.

THE LAST SERVICE FOR THIS COMPLAINT WAS THE FIRST PART ON JULY. THIS IS THE 14TH OF JULY AND THE SAME PROBLEM HAPPENED ON THE HIGHWAY FORCING MY HUSBAND TO EDGE INTO THE SHOULDER OF THE ROAD AND STOP THE CAR, TURN THE ENGINE OFF AND WAIT.

DEALER SAID THEY HAD SEEN OTHER PROBLEMS WITH THE SPARK PLUG FAILURE. THEY REPLACED BOTH THE PLUGS AND FUEL GASKET AND FUEL SENDER AT NO CHARGE. I WAS LUCKY, THE CAR WAS PARKED IN OUR GARAGE WHEN IT FAILED. I HAD NO POWER AT ALL. IF I HAD BEEN ON THE ROAD AT NIGHT ALONE AND THE CAR FAILED, I COULD HAVE BEEN IN SERIOUS DANGER. WHEN I TRIED TO START THE CAR, IT WAS CLEAR IT WAS NOT THE BATTERY BECAUSE I HAD THE RADIO AND LIGHTS JUST NO TURN OVER OF THE ENGINE AT ALL. THE FUEL GAUGE WAS STICKING. WHEN I WOULD FILL THE TANK, OCCASIONALLY, THE DASH INDICATOR WOULD NOT REGISTER THE FILLING. THE NEEDLE EVENTUALLY, HOWEVER, WOULD COME UP TO INDICATE A FULL TANK. SOMETIMES, TURNING OFF THE ENGINE AND TURNING IT BACK ON WOULD CORRECT THE FAILURE. *AK
