All of a sudden the pre-collision system malfunctions and stops working and the lights go on in the dashboard and then causes the cruse control to stop working as well. I took it to Toyota and they stated they did not know what the cause of it would be.

Vehicle was diagnosed with having a left rear speed sensor and speed sensor wire was broken due to a piece of plastic part came separated from the wheel. Have all kinds of lights come on dashboard and flash on and off, until sensor is replaced with new at an astronomical rate, which cannot be replaced at this time. Feel that the vehicle should be considered recalled for this issue, as the wire is just hanging there, attached to the wheel underneath and should be fixed and attached somewhere else, where it is not less likely to be pulled or disruptive on the future, by other vehicles like mine is. Should be on a recall list as I do not know if other Toyota owners are experiencing the same problem. The lights on the dashboard just blink off/on continuously, even when it starts and from the time the vehicle stops. Cannot see the speed on the dashboard when you are driving down the road.

When its moist out. The cruise will auto cancel itself and the pcs failure lights up on the dash. Happens semi often. Dealer states they can't fix it but to bring it in when it happens again. The truck brakes for ghosts as I drive down the highway. They can't fix this either.

Collision avoidance system engaged randomly with no known cause at location traveled on a frequent basis. At between 40-45mph on a sunny day at temperature in upper 60's and a location that I travel multiple times a week, the collision avoidance system engaged on the dash board. There were no cars, guard rails, trees or other major metal objects on or near the road at the time of the incident. Toyota service mgr indicates that there was no data logging of the event and technician was unable to reproduce; indicates that without 'evidance', they cannot make a repair. However, the evidence of intermittent sensor or computer failures is not always available if proper data logging equipment is not installed in the system. Previously, the collision avoidance system had been engaged by an oncoming bus in the adjacent lane (normal daily driving condition, no expectation of collision) at 30mph. Parking collision sensor (left front) was also triggered in minor snowfall at low speed in a parking lot. Vehicle was purchased new from dealer 12/2017 and had all scheduled services.

Loss of dynamic radar-controlled cruise control: Clean sensor, once on city street, then I stopped and restarted the vehicle, it cleared itself, then a few minutes down the road stopped at a stop sign. It came back on. I checked my VIN# and my truck is not listed for the same recall that I have seen others get.

The avoidance collision radar can be intermittent. Sometime, it detects the vehicle in front of me, then stop working and my truck will accelerate towards the vehicle in front of me. At other time, the warning light will come on, saying the sensor needs to be cleaned, even though the windshield is spotless and drop my truck out of cruise control, causing a quick de-acceleration. I was in front of a semi-truck going at highway speed when this happened and the semi-truck came close to hitting me in the rear end. I've had this into my Toyota dealer and they told me that the vehicle software does not record when the collision avoidance system isn't working. I consider this problem to be extremely dangerous and have avoided using my cruise control most of the time.

The contact owns a 2018 Toyota Tundra. While driving various speeds with the cruise control engaged, the pre-collision system malfunction warning indicator illuminated. The contact stated that the warning indicator remained illuminated even after the cruise control was disabled. The vehicle was not taken to a dealer to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 1,500.

Pre-collision sensors. Pre-collision sensor has gone off twice advising me to brake. Both times there was no other vehicle around me nor was there anything to the sides or in front. Took it to the local dealership and they called Toyota corporate (?). was advised there's no fix and to continue driving the vehicle and annotate all factors surrounding my vehicle if it goes off again. Seems like an extremely unsafe alternative to finding out why a pre-collision sensor goes off. I should not feel unsafe driving my vehicle

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!

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.
