NHTSA Complaint #10434153 — 2009 CHEVROLET AVEO

ON THE FIRST INCIDENT, WHEN DRIVING AT 40 MPH STARTED SHAKING LIKE IT WANTED TO STALL AND STOPPED ACCELERATING. THE NEXT DAY WHEN STOPPED AT A LIGHT IT STARTED SHAKING AND THE RPM GAUGE WAS GOING UP AND DOWN. IT DIDN'T HAPPEN AGAIN UNTIL ABOUT A MONTH LATER, WHICH IS WHEN I TOOK IT IN, BUT THE DEALERSHIP COULDN'T REPLICATE THE PROBLEM. IT KEPT HAPPENING -- THE CAR WOULD START SHAKING WHILE DRIVING LIKE IT WANTED TO STALL AND WOULD SLOW DOWN. ONCE WHILE DRIVING IT DROPPED THE ACCELERATION TO ABOUT 20 MPH AND WOULD NOT GO ANY FASTER, THEN JUST LOST POWER TO THE ENGINE. I TOOK IT AGAIN FOR ONE WEEK BUT THEY COULDN'T REPLICATE THE PROBLEM. I GOT THE CAR BACK AND IT WAS FINE FOR ABOUT TWO WEEKS BUT NOW IS HAPPENING REGULARLY. SOMETIMES IT JUST SHAKES QUICKLY BUT SOMETHING THE ACCELERATION COMPLETELY DROPS AND THE CAR WILL JUST STOP WHILE I AM DRIVING, WHICH IS SCARY. I'LL TRY TO ACCELERATE AND NOTHING WILL HAPPEN, THEN FINALLY IT WILL GO AGAIN. SOMETIMES I WILL STOP AND THEN THE CAR WILL LURCH FORWARD. THE RPM GAUGE IS ALWAYS MOVING UP AND DOWN. THERE IS NO PATTERN AS TO WHEN IT HAPPENS. I'VE TAKEN THE CAR IN TWO MORE TIMES AND STILL NOTHING. THEY JUST INSTALLED A DATA RECORDER AND I RECORDED FOUR INSTANCES AND GAVE IT BACK; I'M WAITING TO HEAR THE RESULTS. IT'S VERY DANGEROUS, BECAUSE I WILL BE DRIVING IN TRAFFIC AND MY CAR WILL JUST STOP, AND SINCE I AM NOT BRAKING THERE IS NO INDICATION TO THE CAR BEHIND ME. ALSO, NO LIGHTS ARE COMING ON (NO CHECK ENGINE LIGHT, ETC.). I HAD MY OIL CHANGED THE FIRST TIME SINCE I WAS ABOUT DUE BUT THAT MADE NO DIFFERENCE. *TR
