INITIAL EXPERIENCE WAS ABS ENGAGING WHILE MAKING A TURN THRU ANTISKID GRAVEL. PEDAL IMMEDIATELY WENT SOFT, LUCKILY NOT ON HEAVY TRAVELED ROAD. RETURNED HOME, DISCONNECTED BATTERY, RECONNECTED AFTER A WHILE, ISSUE SEEMED TO HAVE RESOLVED ITSELF. NEXT INCIDENT WAS 12/9/17 DURING A SNOW EVENT HERE IN NE PA. WHEN I CRESTED A SLIGHT HILL AND APPLIED THE BRAKES TO SLOW FOR STOPPED TRAFFIC. (HIGH TRAVELED ROAD) ABS ENGAGED, PEDAL IMMEDIATELY WENT SOFT. I WAS UNABLE TO CONTROL THE CAR WITH BRAKING, SO I STEERED OFF THE ROAD TO THE RIGHT SHOULDER AREA. TO AVOID STRIKING A OBJECT HEAD ON, (CEMETERY HEADSTONE) I WAS ABLE TO STEER BACK TO THE LEFT, BUT THEN HAD TO AVOID A UTILITY POLE. I WAS CONCERNED A) WITH ELECTRICAL WIRES COMING DOWN, B) AIR BAG DEPLOYMENT SINCE VEHICLE IS ONE AFFECTED BY TAKATA SWITCHES. I AVOIDED THE POLE, BUT ENDED UP STRIKING A SUPPORT GUY WIRE. THIS RESULTED IN OVER $3,000.00 DAMAGE TO FRONT OF VEHICLE, BUT LUCKILY AIRBAGS DID NOT DEPLOY. HOWEVER, HAD THE GUY WIRE NOT STOPPED ME I WOULD HAVE SLID BACK OUT INTO TRAFFIC, AS I WAS ON SNOW COVERED GRASSY SURFACE. VEHICLE NOT DRIVEN AFTER THAT. DEALER LOOKED AT VEHICLE IN JANUARY, NO CODES IN COMPUTER. FLUSHED AND REFILLED BRAKE SYSTEM, HAD NORMAL BRAKING. RECENTLY WENT AROUND SAME CORNER AS INITIAL ENTRY, (EARLY MARCH) PROBLEM IMMEDIATELY RECURRED, PEDAL ALMOST TO FLOOR. AS WITH OTHER POSTERS, PUMPING PEDAL DOES RESTORE SOME BRAKE CAPABILITY, BUT ONLY FOR THAT INSTANCE. PEDAL IS SOFT AGAIN DIRECTLY AFTER. I HAVE SPE
