BRAKES LOCK ON CAR. THE BRAKES ARE BEING APPLIED WITHOUT PUSHING THE BRAKE PEDAL. THE BRAKES WILL LOCK AND THE CAR IS NOT ABLE TO GO WITHOUT PRESSING HARD ON THE GAS. THIS HAS OCCURRED 4 TIMES. THE DEALER COULD NOT FIND THE PROBLEM. IT HAPPENED AGAIN ON 06/17/2018. THE BRAKES LOCKED AGAIN AND YOU COULD SEE SMOKE COMING FROM A SMALL FIRE BY THE BRAKE AREA AT THE FRONT WHEELS. THE CAR HAS BEEN TOWED TO THE DEALERSHIP AGAIN.

HAD A NEAR DEATH INCIDENT AT FREEWAY SPEEDS IN HEAVY RAIN WHEN THE CAR LOST TOTAL CONTROL, HYDRO-PLANED FROM THE 2ND TO LEFT LANE AND HIT THE CEMENT BARRICADE ON THE LEFT AND IN THE PROCESS THE STEERING WHEEL IS LOCKED ALONG WITH THE BRAKES AND WITH THAT IMPACT, RICOCHETED ALL THE WAY TO THE RIGHT HAND SHOULDER OF A 4-LANE FREEWAY BEFORE COMING TO A STOP. FREEWAY IS 280 S (SAN FRANCISCO TO SAN JOSE). LOCATION WAS PALO ALTO, JUST A FEW MILES AFTER SAND HILL RD EXIT (MENLO PARK) WHERE THE FREEWAY IS JUST STRAIGHT FOR MILES WITHOUT ANY STEEP CURVES. HAVE DRIVEN SO MANY OTHER BRANDS OVER THE LAST 20 YEARS IN HEAVY RAIN ON THE SAME FREEWAY WITHOUT AN INCIDENT. THE CAR CANNOT HANDLE FREEWAY SPEEDS AND BECAME VERY UNSTABLE. COULD BE DEFECTIVE TIRES, THEIR TECHNOLOGY CONTROLLING THE WET TRACTION WHICH CAUSED HYDROPLANING ETC FORTUNATELY THERE WERE NO OTHER CARS IN PROXIMITY ELSE COULD HAVE BEEN A BIGGER ACCIDENT.

I WAS TRAVELING EAST ON US I90 IN CHARLTON MA IN HEAVY HOLIDAY TRAFFIC KEEPING A SAFE INTERVAL AS CARS KEPT BRAKING OFF AND ON AND SOMEONE A DOZEN CARS UP SLAMMED ON THIER BRAKES CAUSING A CHAIN REACTION. I HIT MY BRAKES HARD ALSO BUT DID NOT SLOW DOWN FAST AS IF I WAS STILL PRESSING ON GAS PEDAL I WAS SLOWING BUT NOT (RIGHT ?) OR FAST ENOUGH AS I WAS STANDING ON BRAKE BUT STILL KEEP MOVING FASTER AHEAD THEN SEEMED RIGHT? THIS HAD HAPPENED A MONTH OR SO BEFORE AND I THOUGHT MAYBE MY RUG HAD SLIPPED UNDER BRAKE PETAL AND OVER MY GAS PEDAL AS IT SEEMED THE HARDER I PRESSED ON BRAKE I STILL KEPT MOVING FORWARD AS IF BOTH WERE BEING PRESSED AT THE SAME TIME IT SEEMED VERY ODD OR ERIE AS I JUST KEPT MOVING FORWARD. I DID MANAGE TO STOP JUST IN TIME BEFORE I HIT HIS BUMPER. LIKE I SAID I THOUGHT AT THE TIME MAYBE THE RUG HAD SLIPPED OR SOMETHING BECAUSE IT HAD SLIPPED OFF THE HOOK ON THE FLOOR BUT IT HAD NOT REALY MOVED THAT MUCH AND I SECURED IT WITH HOOK ON FLOOR AND CHECKED TO MAKE SURE IT WAS STILL SECURE THE SECOND TIME IN JULY 3RD AND IT WAS . SINCE THEN I HAVE READ ABOUT 2014 SONATAS HAVING PROBLEMS WITH THIER BRAKES THAT FITS WHAT HAPPENED EXACTLY ON OVER 800,000
