The contact owns a 2020 Toyota Rav4. The contact stated while driving approximately 60 MPH, the "Lane Departure System" jerked the vehicle into the left lane; the contact steered the vehicle back into his original lane. The contact stated no warning light was illuminated or warning chime had sounded. The contact stated that the failure had occurred twice. The contact stated that he turned off the "Lane Departure System”. The contact had taken the vehicle to a local dealer. The vehicle had not been diagnosed and had not yet been repaired. The manufacturer was informed of the failure. The failure mileage was approximately 40,000.

WHEN THE FEATURE IS ENGAGED, THE CAR CHANGES LANES. HAD IT INSPECTED AND ADJUSTED BY THE DEALER. DEALER SAID "IF I DON'T LIKE THE FEATURE, TURN IT OFF" SO I DO NOT USE THIS "SAFETY" FEATURE AS IT WOULD CAUSE ME TO HAVE AN ACCIDENT. I'VE ONLY TURNED IT ON WHEN I CAN DO SO SAFELY WITHOUT SOMEONE NEAR ME TO SHOW. FEATURE IS ONLY ENGAGED OVER 35 MPH SO WHEN I AM ON THE HIGHWAY.

I HAVE HAD A NUMBER OF INSTANCES WHERE MY VEHICLE'S LANE KEEP ASSIST WILL RANDOMLY JERK ME OUT OF MY LANE. IN SEPT 2020 I EXPERIENCED A SIGNIFICANT EVENT OF THIS HAPPENING WHEN I WAS DRIVING IN THE RIGHT LANE OF AN INTERSTATE AND THE VEHICLE JERKED RIGHT SUDDENLY, PULLING THE VEHICLE INTO THE RIGHT SHOULDER AND ALMOST DROVE ME OFF THE INTERSTATE. ANOTHER SIGNIFICANT INSTANCE HAPPENED ON 1/23/2021. I WAS DRIVING NORTHBOUND ON I-44 AND I WAS IN THE MIDDLE OF 3 LANES. MY VEHICLE SUDDENLY JERKED THE VEHICLE TO THE LEFT INTO THE LEFT LANE OF TRAFFIC. LUCKILY, THE VEHICLE NEXT TO ME SWERVED ONTO THE SHOULDER THINKING I WAS GOING TO HIT THEM. THERE HAVE BEEN OTHER REGULAR INCIDENTS OF THIS HAPPENING, BUT NOT AS SEVERE AS THESE TWO.*DT*DT THE CONSUMER STATED WHILE DRIVING ON I-44, THE VEHICLE SUDDENLY JERKED TO THE LEFT TOWARDS TRAFFIC. THE CRUISE CONTROL WAS NOT ACTIVATED. THE CONSUMER STATED THE REPAIR TECHNICIANS WERE ABLE DULICATE THE FAILURE BUT, UNABLE TO REPAIR IT.

THE TOYOTA ADAPTIVE CRUISE CONTROL KEEPS A SAFE DISTANCE TO THE VEHICLE IN FRONT, SLOWING AND ACCELERATING PROPERLY TO KEEP A SET DISTANCE EVEN DOWN TO A FULL STOP. HOWEVER, WHEN TRAVELING AT ANY SPEED AND ANOTHER CAR ENTERS MY LANE IMMEDIATELY IN FRONT OF MY VEHICLE THE SYSTEM DOES NOT RECOGNIZE THE NEW VEHICLE AND HOW CLOSE IT IS TO THE FRONT OF MY VEHICLE. IT DOES NOT SLOW AT ALL EVEN IF THE DISTANCE TO THE INTRUDER IS ONLY A CAR LENGTH OR LESS. I HAVE TO MANUALLY BRAKE QUICKLY TO PREVENT FOLLOWING TO CLOSE AND CAUSING A POSSIBLE REAR END COLLISION. THIS HAPPENS EVERY TIME A CAR SQUEEZES IN FROM OF ME WITH THE ADAPTIVE CRUSE ON AND IS VERY REPEATABLE. I'VE EXPERIENCED IT IN ANOTHER NEW RAV 4 TOO. THIS HAS BEEN REPEATABLY GOING ON SINCE THE VEHICLE WAS PURCHASED NEW ON JAN, 2020
