2004 Audi S4

IN JANUARY 2009 I ATTEMPTED TO CHANGE THE RIGHT FRONT TIRE ON MY 2004 AUDI S4. I USED THE CAR JACK THAT COMES WITH THE CAR. AFTER LIFTING THE CAR UP ON THE PROPER POSITION (AS EXPLAINED IN THE AUDI USERS MANUAL) THE CAR JACK BROKE APART UNDER THE WEIGHT OF THE CAR. THE GROUND IN MY GARAGE IS EVEN AND MADE OUT OF CONCRETE AND THE AUTOMATIC TRANSMISSION WAS IN P AND THE EMERGENCY BRAKE WAS FULLY APPLIED SO THAT MOVEMENT OF THE CAR WHILE LIFTED WAS IMPOSSIBLE. THE AUDI DEALER I COMPLAINED TO REPLACED THE CAR JACK AND FIXED THE DAMAGE ON THE RIGHT LOWER SIDE OF MY CAR WITHOUT ANY CHARGES. TWO WEEKS AGO I HAD A FLAT ON THE RIGHT FRONT SIDE OF MY CAR AGAIN COMING UP INTERSTATE I 55 FROM CAPE GIRARDEAU MO. WHEN USING THE NEW CAR JACK (SAME MODEL) THAT THE AUDI DEALER HAD GIVEN ME AFTER THE PRIOR INCIDENT. AND AS YOU PROBABLY GUESSED THE SAME HAPPENED AGAIN. THIS TIME I WAS ON THE SIDE OF THE ROAD BUT THE CIRCUMSTANCES WERE NOT MUCH DIFFERENT. AFTER I STOPPED THE CAR, I SELECTED PARK ON THE AUTOMATIC TRANSACTION AND APPLIED THE EMERGENCY CAR BRAKE. AFTER LOOSENING UP THE BOLTS I PLACED THE CAR JACK AS EXPLAINED IN AUDIS USER MANUAL UNDER THE CAR ON THE FRONT RIGHT SIDE AND LIFTED THE CAR UP. THEN I ATTEMPTED TO TAKE OF THE TIRE WHEN THE JACK SUDDENLY GAVE IN AS DONE IN THE FIRST SITUATION EXPLAINED ABOVE. FORTUNATELY THE CAR DROPPED WITH THE ROTOR ONTO THE INSIDE OF THE RIM OF THE TIRE I WAS ABOUT TO PULL OF. I HAD TO CALL A FRIEND WHO WAS BRINGING ME A DIFFERENT CAR JACK SO I COULD PUT ON THE SPARE TIRE. LATER I FOUND OUT THAT THE RIGHT ROTOR WAS SLIGHTLY DAMAGED AFTER DROPPING ONTO THE INSIDE OF THE TIRE RIM. NOBODY WAS HURT BUT I TRULY BELIEVE THAT THIS CAR JACK IS DANGEROUS AS IT DOESNT SEEM TO BE MADE TO CARRY THE WEIGHT OF MY CAR. I WORKED FOR BMW AS A LICENSED CAR MECHANIC IN THE PAST AS WELL WAS A MAINTENANCE CREW CHIEF WORKING ON FIGHTER JETS WELL CAPABLE OF CHANGING A TIRE; IF THIS HAPPENS TO ME THEN I BELIEVE IT CAN HAPPEN ANYTIME TO ANYBODY USING THIS CAR JACK
