MY AVEO IS SUPPOSED TO HAVE A WARNING LIGHT TO COME ON WHEN THE ENGINE HAS TO BE SERVICED. APPARENTLY, THIS LIGHT DID NOT COME ON FOR THE WARNING THAT THERE WAS SOMETHING WRONG WITH THE VEHICLE THAT I NEED TO FIND OUT ABOUT. DRIVING TO ME(THE VEHICLE WAS DRIVEN BY MY CHILD OF 28 YEARS WITH A 3 MONTH OLD IN A REAR CAR SEAT) TO PICK ME UP TO TAKE ME TO WORK THE CAR JUST STOPPED. IN THE MIDDLE OF ONGOING TRAFFIC. THANKFULLY THE CAR WAS NOT HIT BUT THE POLICE AS WELL AS MY BROTHER (WHOM WAS ON HIS WAY TO WORK) WERE ABLE TO GET THE CAR TO THE SIDE OF THE ROAD. HER FATHER (HE WAS CALLED) SHOWED UP WITH A TOW ON ITS WAY TO TAKE IT TO MY MECHANIC. IT WAS DETERMINED THAT THE TIMING CHAIN/BELT WENT. BECAUSE THE CAR WAS IN MOTION IT ALSO CAUSED THE BENDING OF 2 PISTONS. IN ORDER TO FIX IT PROPERLY THIS MECHANIC WAS NOT ABLE TO DO SO. I WAS INFORMED HOWEVER THAT ALL AVEOS FROM THIS MODEL OR YEAR HAS SHOWN TO HAVE THE TIMING BELT/CHAIN TO MALFUNCTION BETWEEN THE MILEAGE OF 40,000- 80,000 MILES. SO, I AM TRYING TO FIND OUT IF THERE IS A RECALL ON FIRST THE WARNING LIGHT NOT INDICATING THERE WAS SOMETHING WRONG AND SECOND, THE TIMING CHAIN/BELT MALFUNCTIONING REPEATEDLY BETWEEN THE MILES OF 40,000-80,000 MILES. I LOVE MY AVEO BECAUSE IT IS THE PERFECT SIZE, EXCELLENT ON GAS AND BEING A 2004 MODEL THERE IS ONLY ABOUT 66,000 MILES OR SO ON IT. I AM TRULY MISSING MY AVEO AND WOULD APPRECIATE IT IF SOMEONE CAN HELP ME GET IT BACK TO NORMAL SO I CAN TAKE IT HOME. I HAVE TO SAY THAT THIS IS MY FIRST REAL CAR AND I WOULD RATE IT IN THE TOP TEN VEHICLES TO PURCHASE FOR ITS TOTAL ECONOMICAL QUALITIES. SO, PLEASE LET ME KNOW AT YOUR EARLIEST CONVENIENCE.
