NHTSA Complaint #11080776 — 2018 TOYOTA TUNDRA

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.
