2018 TOYOTA TUNDRA Complaints

TL* THE CONTACT OWNS A 2018 TOYOTA TUNDRA. WHILE DRIVING 35 MPH, THE PEDESTRIAN WARNING INDICATOR INTERMITTENTLY ILLUMINATED AND THE BRAKE WARNING INDICATOR ILLUMINATED; HOWEVER, THE VEHICLE FAILED TO STOP. THE VEHICLE WAS TAKEN TO TEJAS TOYOTA (19011 HIGHWAY 59 N, HUMBLE, TX 77338), BUT THE FAILURE WAS UNABLE TO BE DUPLICATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS APPROXIMATELY 7,800.

RECEIVED A PRE-COLLISION MALFUNCTION AND TRAILER BRAKE ERROR MULTIPLE TIMES. WAS INFORMED THE FAULT OCCURRED DUE TO COLD WEATHER. WAS INFORMED THAT RECALL SOFTWARE UPDATE WOULD RESOLVE ISSUE BUT HAS OCCURRED TWICE SINCE WITH THE LATEST OCCURRING 1/12/2018. ALSO, HAVE BEEN EXPERIENCING A RATTLING/VIBRATION NOISE COMING FROM THE PASSENGER SIDE DASH SINCE PURCHASING THE VEHICLE IN OCTOBER; TOYOTA HQ INVOLVED. LATEST DIAGNOSIS IS A FAULTY ECU; AWAITING REPAIR AND VALIDATION.

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.
