PURCHASED VEHICLE NEARLY NEW FROM A DEALER IN MAY 2005. HANDLING AND STEERING WERE STABLE AND PREDICTABLE, BUT HAS DETERIORATED SIGNIFICANTLY SINCE ROUGHLY 40,000 MILES. I NOW EXPERIENCE SEVERE SLOPPINESS IN THE STEERING, EXCESSIVE BODY-ROLL WHILE TURNING AND THE CAR IS BUFFETED IN EVEN LIGHT WINDS, ESPECIALLY AT SPEED (55 TO 65 MPH) ON HIGHWAYS. UNDER LIGHT-TO-MODERATE ACCELERATION, I OCCASIONALLY EXPERIENCE STRONG TORQUE STEER WHILE RUNNING OVER VARYING ROAD SURFACES OR IMPERFECTIONS AND WILL VEER SUDDENLY TO THE RIGHT OR LEFT. LOWER CONTROL ARM BUSHINGS ARE SEVERELY WORN AND ARE TO BE REPLACED. THESE HAVE BEEN A PREMATURE WEAR ITEM ON THIS MODEL'S PREDECESSOR, THE DAEWOO LANOS. COMPARED TO OTHER VEHICLES, THE EARLY WEAR OF SUSPENSION AND STEERING COMPONENTS ON THIS MODEL IS A POTENTIALLY FATAL SHORTCOMING. *JB

WHILE STOPPED AT RED LIGHT, OUR 2004 CHEVY AVEO WAS STRUCK FROM BEHIND BY A VEHICLE TRAVELING ABOUT 25-45 MPH, WHICH PROPELLED THE AVEO INTO THE CAR IN FRONT OF IT.
