VEHICLE WAS BEING DRIVIN ON A TWO LANE HIGHWAY AND ALL OF THE SUDDEN THE FRONT RIGHT FELL TO THE GROUND AND THE CAR SPUN OUT AND SLID INTO A DITCH. THE FRONT RIGHT BALL JOINT FAILED AND BROKE APART. MY MECHANIC SAYS HE REPLACES BALL JOINTS ON THESE CARS AT THE RATE OF FIVE CARS PER MONTH. WHILE BEING REPAIRED, I HAD THE CONTROL ARM BUSHINGS, TIE RODS, AND SWAY BAR ENDLINKS REPLACED AGAIN BECAUSE THERE WERE RATTLING AND CLUNKING AGAIN. MY BROTHER WORKS AT A CHEVY DEALER AND HE SAYS THAT COBALT'S/G5'S/HHR'S COME IN ALL THE TIME FOR FRONT SUSPENSION PROBLEMS. GM KNOWS OF THESE ISSUES BUT DOES NOT WANT TO DO ANYTHING FOR IT'S CUSTOMERS WHEN THE WARRANTY RUNS OUT. A CRASH CAN VERY WELL HAPPEN IF ONE OF THESE COMPONENTS FAILS WHEN DRIVING AND THAT IS WHAT HAPPENED TO ME. EVERY SUSPENSION PART ON THESE CARS IS FAULTY. PLEASE LOOK INTO THE SUSPENSION PROBLEMS ON THESE CARS FURTHER. THANK YOU. *TR
