Owner Complaints (6)
While driving at 75 mph to pass an 18-wheeler, your truck suddenly began idling erratically and lost speed, causing the service engine light and TRAC light to come on. This unexpected loss of power created a dangerous situation with other vehicles on the highway, and your truck wouldn't start when you pulled over. After diagnosis, a mechanic determined the fuel pump was the culprit. The repair involves replacing the fuel pump, which costs over $1,200 in parts alone.

The contact owns a 2020 Toyota Tacoma. The contact stated while driving approximately 80 MPH, the brakes activated independent of the driver input and the vehicle slowed to 60 MPH abruptly. There was no warning light illuminated. The vehicle was not taken to a dealer to be inspected. The manufacturer was not informed of the failure. The failure mileage was approximately 20,000.
THIS MORNING I ACTIVATED MY CRUISE CONTROL (CC)AS I NORMALLY WOULD AT 55 MPH. IMMEDIATELY MY TRUCK BEGAN ACCELERATING UNTIL I FINALLY DISENGAGED CC WHEN THE SPEED REACHED 83-85 MPH. IT WAS STILL ACCELERATING AT THE TIME I DISENGAGED IT. I ATTEMPTED TO RECREATE THE INCIDENT WITH NO LUCK. BEFORE THE INCIDENT, I WAS DRIVING IN A CITY ENVIRONMENT AT SPEEDS LESS THAN 55 MPH, SO THERE WAS NO WAY I HAD PREVIOUSLY SET THE CC TO A HIGH SPEED THAT WOULD HAVE CAUSED THIS TO HAPPEN HAD I HIT RESUME.
SYSTEM WILL OCCASIONALLY SUDDENLY DECELERATE AS I AM PASSING, USUALLY A LARGE TRUCK. I WILL BE IN ADAPTIVE CRUISE CONTROL AND AS I GET ABREAST OF THE TRAILER, THE VEHICLE WILL SUDDENLY DECREASE SPEED BY 10-20 MPH, THEN ACCELERATE BACK TO THE SET SPEED. THIS, OBVIOUSLY, HAS THE POTENTIAL TO CREATE A REAR END COLLISION IF SOMEONE IS FOLLOWING AND NOT PAYING FULL ATTENTION, ESP IF THERE ARE MULTIPLE CARS FOLLOWING. THIS HAS HAPPENED MULTIPLE TIMES.
THE PRE COLISION SYSTEM IS FAULTED OUT DUE TO THE SENSOR BEHIND THE WINDSHILD
