2018 TOYOTA TUNDRA Complaints

PCS SYSTEM RANDOMLY TURNS ITSELF OFF, RENDERING RADAR CRUISE CONTROL AND OTHER SAFETY FEATURES USELESS. STARTED WITH LESS THAN 500 MILES ON THE CAR. IT HAS BEEN IN THE DEALERSHIP 3 OCCASIONS AT THIS POINT WITH ALL UPDATES COMPLETED AND PCS LIGHT STILL ILLUMINATES ON ITS OWN.

THE PCS "PRE-COLLISION SYSTEM" SHUTS OFF ALL THE TIME! WHEN CRUISE CONTROL IS ON AND IS SUPPOSED TO SLOW DOWN BY ITSELF WHEN THERE'S ANOTHER CAR IN FRONT OF YOU ACTUALLY ACCELERATES MY VEHICLE THAT CAN CREATE A SEVERE ACCIDENT BY CRASHING INTO THE VEHICLE IN FRONT OF ME! THE SYSTEM IS DESIGNED ON THE RADAR BASE SYSTEM THAT IS SUPPOSED TO SLOW DOWN THE VEHICLE TO AVOID AN ACCIDENT AND IT ACTUALLY SPEEDS IT UP WHICH CAN CAUSE A FATALITY!

TOYOTA'S PRE COLLISION SENSOR IS UNRELIABLE AND INTERMITTENTLY PRODUCES AN ERROR "PCS SENSOR UNAVAILABLE -- CLEAN SENSOR". THE SAFETY PORTION OF THIS COMPLAINT COMES WHEN DYNAMIC CRUISE CONTROL IS SET. WHEN THE SENSOR NO LONGER DETECTS A VEHICLE IN FRONT OF YOU, AND THERE IS CLEARLY THERE, THE VEHICLE WILL ACCELERATE AT A HIGH RATE OF SPEED BEFORE THE ERROR SHOWS ON THE DASH CLUSTER IF THE CRUISE CONTROL IS SET ABOVE THE TRAFFIC FLOW. I EXPECT AND REALIZE THAT THIS SITUATION COULD OCCUR, AND I AVOID USING THE SYSTEM. HOWEVER, IF SOMEBODY NOT FAMILIAR WITH THIS FAULT IS USING THE PCS SENSOR AND DOES NOT REALIZE THIS PROBLEM, THEY WILL END UP REAR ENDING ANOTHER VEHICLE, POSSIBLY AT A HIGH RATE OF SPEED BEFORE THE SYSTEM SHUTS ITSELF OFF AND LETS OFF THE THROTTLE. I KNOW I AM NOT THE ONLY PERSON DEALING WITH THIS ISSUE. SEVERAL OTHERS ON DIFFERENT FORUMS HAVE DESCRIBED SIMILAR SITUATIONS WHERE ACCIDENTS HAVE BEEN NARROWLY AVOIDED BECAUSE OF THIS FAULT. THE LOCAL TOYOTA DEALERSHIP HAS BEEN HELPFUL IN RESOLVING THIS ISSUE AND HAVE PULLED CODES FOR A FORWARD CAMERA COMMUNICATION ISSUE. A NEW CAMERA HAS BEEN ORDERED AND WILL BE INSTALLED NEXT WEEK.

VEHICLE PRE COLLISION SYSTEM (PCS) MALFUNCTION/OFF LIGHT WILL ILLUMINATE UPON ENGINE START AND TURN OFF ONCE SEVERAL MINUTES HAVE PASSED WHEN DRIVING. LIGHT SEEMS TO ILLUMINATE MORE OFTEN WHEN THE TEMP IS <40F. UNKNOWN IF THE PRE COLLISION SYSTEM IS ACTUALLY WORKING WHEN THE MALFUNCTION LIGHT ILLUMINATES.

THE PRE COLLISION WARNING LIGHT ILLUMINATES A VARIOUS TIMES. THE CRUISE CONTROL WILL NOT WORK WHEN ILLUMINATED. THE SENSOR HAS BEEN KEPT CLEAN. IT DOES NOT GIVE A FAILURE CODE AT THE DEALER. IT WAS REPROGRAMED. THE PRE COLLISION BRAKING WAS A MAJOR FEATURE IN MY BUYING PROCESS AND IT DOES NOT WORK CORRECTLY.

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.

MULTIPLE EVENTS. 2500 MILES ON VEHICLE. WHILE DRIVING 70MPH IN CRUISE CONTROL THE PRE-COLLISION WARNING CAME ON AND VEHICLE APPLIED BRAKES FORCEFULLY WITHOUT ANY VEHICLE AHEAD OF MY VEHICLE UNTIL I TURNED OFF CRUISE CONTROL. AFTER THE EVENT THE TRALER BRAKE MALFUNCTION STATEMENT AND WARNING LIGHTS WERE ON. PRE -COLLISION FAILURE LIGHT RESET AFTER KEY CYCLED OFF AND BACK ON. FAILURE OCCURRED MULTIPLE TIMES IN MULTIPLE DRIVING CONDITIONS, CURRENTLY TRAILER BRAKE FAILURE LIGHT IS ILLUMINATED. EACH TIME I HAD TO EXIT OR PULL OVER AND STOP VEHICLE, CYCLE KEY TO HAVE WARNING CLEAR.

PRE-COLLISION SYSTEM WARNING LIGHT IS ON STATING THAT THE SYSTEM IS OFF IT WILL NOT FUNCTION

DRIVING TRUCK ON FREEWAY WITH CRUISE CONTROL ON AT 80-85 MPH. ROAD WAS FLAT AND IT WAS A CLEAR SUNNY DAY. NO CARS NEAR THE TRUCK AND THE PRECOLLISION SENSOR WENT OFF CAUSING THE TRUCK TO ALMOST EMERGENCY BRAKE BEFORE I TURNED CRUISE CONTROL OFF. THERE WAS NOTHING IN FRONT OF THE TRUCK TO CAUSE THIS. A FEW WEEKS BEFORE THE PRECOLISION SENSOR AND LANE DEPARTURE SEMSOR WENT OFF AND TIL ME THE TRUCK NEEDED TO BE TAKEN TO DEALER. THE SENSORS HAVE GONE OFF A FEW TIMES SAYING THEY ARE INOPERABLE.

INTEGRATED BRAKE CONTROLLER NOT FUNCTIONING. TOOK IT TO DEALER A WEEK AND NOT RESOLVED.
