2010 Audi A4

THE COIL SPRINGS BROKE ON THIS VEHICLE ON 2 SEPARATE OCCASIONS. THE LEFT FRONT COIL SPRING BROKE WHILE IT WAS BEING DRIVEN BY MY HUSBAND ON 7/24/19. THE LEFT REAR COIL SPRING BROKE WHILE I WAS TURNING OUT OF MY DRIVEWAY ON 4/21/20. THE VEHICLE HAS OVER 81,000 MILES, BUT IS IN VERY GOOD CONDITION. I AM CAREFUL TO AVOID POT HOLES WHILE DRIVING, SO I DON'T BELIEVE THE CAUSE IS DUE TO MY DRIVING HABITS. THE PHOTO I HAVE PROVIDED SHOWS THE BREAK IS NOT DUE TO RUST. THIS HAS NEVER HAPPENED WITH ANY VEHICLE THAT I HAVE DRIVEN IN THE 50+ YEARS I HAVE BEEN DRIVING . MY UNDERSTANDING IS THAT A BROKEN COIL SPRING IS VERY DANGEROUS AND CAN CAUSE AN ACCIDENT PARTICULARLY IF IT PUNCTURES A TIRE WHILE DRIVING. MY SUSPICION IS THAT THE COIL SPRINGS ARE DEFECTIVE GIVEN THAT THE BREAKS OCCURRED WITH 2 DIFFERENT COIL SPRINGS. SINCE THIS HAS HAPPENED TWICE, I CHOSE TO REPLACE ALL THE COIL SPRINGS IN THE CAR BECAUSE I FEAR FOR MY SAFETY. I UNDERSTAND THAT VOLKSWAGON, OF WHICH AUDI IS A PART OF, RECALLED OVER 56,000 VEHICLES LAST YEAR DUE TO DEFECTIVE COIL SPRINGS. HOWEVER, I CANNOT FIND ANY INFORMATION REGARDING A RECALL FOR AUDI COIL SPRINGS.
