NHTSA Complaint #10073196 — 2000 CHEVROLET IMPALA

PERIODIC TRANSMISSION SLIP FROM INITIAL DATE OF PURCHASE - DEALER COULD NOT DUPLICATE WHEN TAKEN IN FOR SERVICE, UNTIL OUT OF WARRANTY. REFLASH E-PROM/UPDATE DONE AT 75K MILES TO CORRECT PROBLEM. NOW AT 110K DEALER SAYS NEW TRANSMISSION IS NEEDED AS CAR IS EXHIBITING SAME PROBLEMS. CAR HEADLIGHTS GO OUT WHEN USING HIGH BEAMS. CAR HAS LOST ALL POWER TWICE WHEN DRIVING AND COMPLETELY SHUT OFF, THUS CAUSING A SIGNIFICANT STEERING PROBLEM UNTIL THE CAR COULD BE STOPPED. GROUNDING WIRES ADDED TO SEE IF CORRECTION COULD BE MADE. LIGHTS & CAR HAVE NOT QUIT YET, BUT TRANSMISSION CONTINUES TO EXHIBIT SHIFTING PROBLEMS WITH CHECK ENGINE LIGHT COMING ON. WHEN CAR IS SHUT OFF THE ENGINE LIGHT WILL GO OUT AND NOT COME BACK ON AND THE CAR WILL RESET IT SELF AND RUN OKAY FOR AWHILE. THE CAR ALSO EXHIBITS A LOUD WHINING NOISE WHEN THE SLIPPAGE / JERKING IS ABOUT TO OCCUR. GM WILL NOT ALLOW CONVERSATION WITH ANYONE BUT A CUSTOMER SERVICE PERSON. ALL FILE NUMBERS GIVEN TO ME BY GM PERSONNEL WHEN CAR WAS UNDER WARRANTY ARE NOT LOADED INTO THEIR DATA BASE, THUS NOTHING CAN BE DONE, MILEAGE IS TOO HIGH AND THESE THINGS ARE EXPECTED TO HAPPEN. *NM
