2018 Toyota Tundra UNKNOWN OR OTHER

PRE COLLISION LIGHT COMES ON WITH THE VEHICLE ONLY HAVING 300 MILES ON IT. CYCLE ON AND OFF TO RESET BUT THE LIGHT STAYS ON. RECOMMEND REPLACING THE WIRING HARNESS TO THE PCS. POLLED OTHER 2018 TUNDRAS AND 85% OF THE THEM ARE HAVING THE SAME ISSUE. THE FEBRUARY RECALL DID NOT FIX THIS ISSUE. LIGHT WILL COME ON ONCE THE TRUCK HAS BEEN TURNED ON.

PRE COLLISION SENSOR LIGHT COMES ON AT VARIOUS TIMES DASH READS "PRE COLLISION UNAVAILABLE" CAR HAS 500 MILES ON IT AND IS A WEEK OLD, I HAVE TAKEN CAR TO THE DEALER AND WAS TOLD IT SHOULD ONLY HAPPEN IF THE VEHICLE WAS IN AN ACCIDENT, IT WAS NOT IN AN ACCIDENT, THE SENSOR COMES ON AND OFF AT VARIOUS TIMES, SPEEDS.

THE PRECOLLISION WARNIG SYSTEM KEEPS MALFUNCTIONING FOR NO REASON. I HAVE THEM REPLACE 3 SENSORS, WINDSHIELD CAMERA AND FULL SAFETY HARNESSES ALREADY. HUNDREDS F OTHERS HAVE THIS ISSUE. EVEN THE REGIONAL TECH FOR TOYOTA HAS GIVEN UP AND TOLD ME TO CALL TOYOTA CORPORATE. BUT CORPORATE SAYS IT DOESN'T EFFECT THE SAFETY OF THE VEHICLE. THE SYSTEM DOESN'T WORK WHEN IT'S MALFUNCTIONING, MEANING SOMEONE WILL GET HIT WITHOUT THE SAFETY SYSTEM ENGAGING. HAPPENS ALL THE TIME SUNNY DAY, RAINING, HOT OR COLD. BEEN HAPPENING SINCE JUNE IN FIRST 1000 MILES OF OWNERSHIP

THE INTRINSIC TRAILER BRAKE CONTROLLER DID NOT WORK PROPERLY. THE GAIN COULD NOT BE SET INITIALLY. THE DEALERSHIP COMPUTER SYSTEM COULD NOT DETECT THE PROBLEM. THE ONLY WAY THE PROBLEM WAS RECOGNIZED WAS BY ATTACHING A TRAILER OR A TRAILER SIMULATOR TO THE TRUCK. THE DEALERSHIP NOTED THAT ALL THE 2018 TUNDRA TRUCKS ON THEIR LOT HAD THE SAME PROBLEM. THIS IS A SERIOUS PROBLEM THAT COULD LEAD TO ACCIDENTS IF THE DRIVER IS NOT AWARE THAT THE TRAILER BRAKING SYSTEM IS NOT WORKING. WE WERE PERSISTENT AND THE DEALERSHIP DID REPLACE THE CONTROLLER WITH ONE THAT DID WORK. HOWEVER, THIS CONTROLLER COULD NOT BE ORDERED FROM TOYOTA, BUT ONLY FROM THE SUPPLIER THAT MAKES THEM FOR TOYOTA. AFTER OUR TRUCK WAS AFFECTED, WE FOUND MANY REPORTS OF THE SAME PROBLEM ON THIS TRUCK. THIS PROBLEM WAS DETECTED IMMEDIATELY AFTER WE PURCHASED THE TRUCK BY THE TECHNICIAN WHO INSTALLED THE GOOSENECK HITCH.
