NHTSA Complaint #11323299 — 2020 FREIGHTLINER CASCADIA

HAVE HAD SEVERAL FREIGHTLINERS FROM COLUMBIAS TO CASCADIAS, THEY ALL HAVE HAD ONE THING IN COMMON. THEY ALL LEAK WATER UNDER RAINY CONDITIONS. THE WINDSHIELD, THE DRIVER'S DOOR AS WELL AS THE DOOR ON THE SIDE OF THE AD SLEEPER. DOESN'T MATTER IF IN MOTION OR SETTING STILL IT LEAKS WATER. SAD PART IS I HAVE A 2020. THIS TRUCK WAS ALSO PURCHASED WITH AN ADVANCE WARNING SYSTEM THAT WILL SELF APPY THE BRAKES TO SLOW THE TRUCK DOWN. I HAVE HAD SEVERAL INSTANCE OF GOING OVER A BRIDGE WHERE THE TRUCK WILL MOMENTARILY BRAKE FOR NO APPARENT REASON. NOTHING IN FRONT OF ME OR TO THE SIDE. THIS HAPPENS FOR A SPLIT SECOND BUT IS FUSTRATING. THE OTHER, AND MORE IMPORTANT ISSUE HAPPENED ABOUT 4 MONTHS AGO WHILE TRAVELING DOWN THE HIGHWAY AT 65 MPH. A VEHICLE WAS IN FRONT OF ME WHEN THE DRIVER STARTED SLOWING DOWN AND USED HIS TURN SIGNAL WHEN BEGINING TO EXT THE HIGHWAY. I HEARD SEVERAL BEEPS ON THE DASH, THERE WAS AN AUDIBLE SOUND AND THE TRUCK WENT INTO A FULL EMERGENCY BRAKING CONDITION WHIHC INCLUDED THE TRAILER TOO. THE TRAILR STARTED TO FISHTAIL AND SKIDMARKS FROM THE TIRES. I TRIED TAPPING THE BRAKES SEVERAL TIMES BUT NOTHING CHANGED. THE TRUCK SLOWED TO 20MPH AND BRAKES RELEASED. THE TRUCK BEHIND ME PASSED ME ON SIDE WITH THE DRIVER GIVING ME THE BIRD. I HAD NO CONTROLL OVER WHAT HAPPENED!
