I HAVE REALLY GOOD DRIVING RECORD WITH NO ACCIDENT & NOT EVEN 1 TICKET IN THE PAST 20 YEARS BEFORE THESE 2 ACCIDENTS & WE'VE HAD THE CAR FOR 6.5 YEARS. 1ST ACCIDENT HAPPENED ON 4/11/14 AT 9:14AM. TRAFFIC WAS BAD DURING THE MORNING RUSH HOUR SO ALL CARS WERE TRAVELLING SLOWLY. I WAS ON FWY 5 HEADING S TO THE FWY 55 S RAMP IN CA. MATRIX (1ST CAR) SUDDENLY STOPPED WHILE ALL OTHER CARS WERE STILL MOVING FORWARD. EQUINOX (2ND CAR) STOPPED & I IMMEDIATELY SLAMMED MY FOOT ON THE BRAKE PEDAL. HOWEVER, I DIDN'T FEEL THE CAR STOPPING AT ALL & I THOUGHT I HEARD THE ENGINE ROARING, BUT THEN THOUGHT IT WAS ONLY MY ILLUSION. SINCE THE DAMAGE WAS ONLY BUMPERS & HEADLIGHTS WE JUST LET INSURANCE HANDLED IT & MOVED ON WITH OUR LIFE. HOWEVER, I DID START DRIVING EXTRA CAREFULLY AFTER THIS INCIDENT. 2ND ACCIDENT HAPPENED ON 6/23/14 AT 8:40AM. AGAIN, TRAFFIC WAS BAD DURING MORNING RUSH HOUR. I WAS ON JAMBOREE IN IRVINE, CA HEADING TOWARDS NEWPORT BEACH. I WAS WAITING FOR THE RED LIGHT ON JAMBOREE AT THE 405 N BOUND EXIT INTERSECTION IN THE 2ND LANE FROM LEFT (TOTAL 4 LANES). THERE WERE ALREADY 2 ACCIDENTS AROUND THERE & LIGHT HAD JUST TURNED GREEN. ALL CARS WERE MOVING VERY SLOWLY DUE TO ACCIDENTS NEARBY. YUKON HAD ALREADY PULLED INTO THE INTERSECTION & SUDDENLY STOPPED. I WAS STILL BEHIND THE LINE WITH SOME DISTANCE & SLAMMED ON BRAKE IMMEDIATELY BUT DIDN'T FEEL THE CAR STOPPING UNTIL HITTING YUKON. I HEARD BRAKE SOUND AND ENGINE ROARING AGAIN WHILE MY FOOT WAS ON THE BRAKE PEDAL. THIS TIME THE
