2008 Lexus IS complaints

I PURCHASED 2 BRAND NEW MICHELIN PILOT SPORT A/S PLUS 225/45/ZR17 91Y FOR MY 2008 LEXUS IS 250 INSTALLED AS FRONT TIRES AT COSTCO. BEFORE LESS THAN 24 HOURS OF INSTALLED, AND LESS THAN 15 MILES OF USE, ONE OF THEM LOOSE THE AIR PRESSURE, THE TPMS ALERT ME OF LOW TIRE, I STOP AT NEAREST GAS STATION (ABOUT 2 MILES FROM THE MOMENT OF THE TPMS ALERT) AND IN EFFECT THE LEFT FRONT TIRE WAS LOW, I START TO INFLATE THE TIRE AND BEFORE THE TIRE WAS COMPLETELY INFLATED, A BLOWOUT OCCURRED CAUSING AN INJURY IN MY FACE. *TR

I AM WRITING TO REPORT A BRAKE FAILURE ON MY NEW LEXUS IS 350 WHILE PARALLEL PARKING. I BACKED MY CAR INTO THE SPACE, AND THEN TOUCHED THE GAS LIGHTLY TO MOVE IT FORWARD TO CLOSE THE 4 TO 5 FOOT GAP. I PUT FOOT ON BRAKE AND PUSHED DOWN. BRAKE WENT DOWN CLOSE TO FLOOR AND DID NOT STOP CAR. IT KEPT MOVING SLOWLY FORWARD AND BUMPED INTO VEHICLE PARKED AHEAD OF ME, SCRATCHING BOTH IT AND MY CAR. WITH CAR IN NEUTRAL I PUSHED DOWN THE BRAKE PEDAL TWICE MORE AND IT WELT CLOSE TO FLOOR. ON THIRD ATTEMPT IT CAME BACK TO NORMAL. I LEFT NOTE FOR OWNER OF CAR AHEAD OF ME AND TOOK CAR TO LEXUS OF PLEASANTON. THEY KEPT CAR FOR 2 DAYS BUT SAY THAT THEY CAN'T DUPLICATE PROBLEM AND THAT IT IS SAFE. A QUICK GOOGLE SEARCH OF "LEXUS BRAKE FAILURE" DEMONSTRATES OTHER SIMILAR PROBLEMS WITH OTHER LEXUS CARS. LEXUS REFUSES TO ACKNOWLEDGE THIS PROBLEM OR DEAL WITH. THEY SAY THAT IF THEY CAN'T DUPLICATE THE PROBLEM THEY DON'T BELIEVE IT EXISTS. A FRIEND OF MY WIFE SAYS HER LEXUS DID THE SAME THING BUT LEXUS TOLD HER THAT NOTHING IS WRONG WITH IT. LEXUS HAS A PROBLEM WITH ITS ABS BRAKING SYSTEM , BUT IS STONEWALLING THE PROBLEM. SOONER OR LATER SOMEONE WILL BE SERIOUSLY INJURED OR KILLED BECAUSE OF LEXUS FAILURE TO ACKNOWLEDGE THIS PROBLEM. *TR
