NHTSA Complaint #10428878 — 2009 CHEVROLET AVEO

I BOUGHT MY 2009 CHEVY AVEO A YEAR AND A HALF AGO. WHEN MY CAR WAS AT 6,000 MILES, I DROVE MY CAR TO SCHOOL AND PARKED IT IN A PARKING GARAGE. WHEN I RETURNED TO MY CAR AT THE END OF THE DAY IT WOULD NOT START. MY CAR WAS TOWED TO A DEALERSHIP AND A FAULTY FUEL PUMP WAS REPLACED. WHEN MY CAR REACHED 16,000 MILES I BEGAN EXPERIENCING SHAKING AT STOP LIGHTS AND STOP SIGNS, AND VERY SLOW DELAYED ACCELERATION WHEN STARTING TO DRIVE AFTER STOPPING. THE SHAKING AND DELAYED ACCELERATION WOULD OCCUR RANDOMLY YET WAS VERY LIKELY WHEN MY AIR CONDITIONING WAS ON. I BROUGHT MY CAR TO THE DEALERSHIP YET THEY SAID THE PROBLEM COULD NOT BE REPLICATED. MY CAR IS CURRENTLY AROUND 22,000 MILES. OVER THE LAST WEEK MY CAR HAS BEGUN DECELERATING AND THEN SUDDENLY LUNGING FORWARD WHILE I AM DRIVING. THE DECELERATION AND LUNGING FORWARD IS HAPPENING WHEN I AM DRIVING ON LOCAL ROADS AT ABOUT 30MPH AND WHEN I AM ON A HIGHWAY DRIVING AROUND 70MPH (AND EVERYTHING IN BETWEEN). TODAY, PULLING OUT OF A PARKING LOT, MY CAR WAS VERY DELAYED IN ACCELERATION. WHEN I STOPPED AT A STOP LIGHT, MY CAR BEGAN SHAKING AND THEN SHUT OFF. THIS PROBLEM IS SPORADIC, YET INCREASINGLY WORRISOME AND DANGEROUS. DEALERSHIPS HAVE NOT IDENTIFIED A PROBLEM AND INSIST THERE IS NOTHING THEY CAN DO. *TR
