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.

The precollision warnig system keeps malfunctioning for no reason. I have them replace 3 sensors, windshield camera and full safety harnesses already. Hundreds F others have this issue. Even the regional tech for Toyota has given up and told me to call Toyota corporate. But corporate says it doesn't effect the safety of the vehicle. The system doesn't work when it's malfunctioning, meaning someone will get hit without the safety system engaging. Happens all the time sunny day, raining, hot or cold. Been happening since June in first 1000 miles of ownership

Toyota informed me through mail to my address that my new 2018 Toyota Tundra "fail to conform to Federal Motor Vehicle Safety Standards (FMVSS) no.208, " "occupant crash protection, " and 214, "side impact protection." When I called the customer service number provided 1-888-270-9371 to ask if they would be willing to cover the cost of taking the vehicle to an alternate repair facility located on my island, they refused, not only did they refuse but they claimed that only a Toyota authorized dealer could perform the repair. When I asked how I was suppose to deal with the safety recall without an option to bring my vehicle to an authorized dealer, I was told that I would just have to figure that out on my own, when I asked for the response in writing they also claimed that Toyota would not provided that.

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 Tundra 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.

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.

The intrinsic trailer brake controller did not work properly. The gain could not be set initially. The dealership computer system could not detect the problem. The only way the problem was recognized was by attaching a trailer or a trailer simulator to the truck. The dealership noted that all the 2018 Tundra trucks on their lot had the same problem. This is a serious problem that could lead to accidents if the driver is not aware that the trailer braking system is not working. We were persistent and the dealership did replace the controller with one that did work. However, this controller could not be ordered from Toyota, but only from the supplier that makes them for Toyota. After our truck was affected, we found many reports of the same problem on this truck. This problem was detected immediately after we purchased the truck by the technician who installed the gooseneck hitch.
