“The integrated brake controller works intermittently. Receive two errors that state trailer wiring type or connection fault and pre-collision system malfunction . After the error is received, the trailer brakes no longer function. If the vehicle is turned off and on again the errors go away and the brakes will function again. The problem seems to occur most often when using the manual switch on the controller. Both truck and trailer are new (less than 6 months old).”

“I bought 2020 Toyota Tundra 1794, black. I love this truck, but it annoy me when every time I start the vehicle and drive about 15miles/hour I hear and feel a clunk sound under the front drive side, and feel it on the gas pedal. I heard this sound after 5 days since I bought it, I called the dealer and set up appointment. I brought it to dealer where I bought it, they cannot fix it. That problem bothers me all the tine. I don't know that to do with it.”

“NOTE: Toyota has confirmed this issue, but is unable to resolve this. When the SOS button is pressed, the DCM module is supposed to send the proper VIN number and location to the call center. The call center does not receive the proper VIN number and pulls up the wrong person / location. In my case, if an emergency occurred, they would send emergency assistance to a vehicle located in another state entirely. This is not because the wrong owner is assigned to their system. They can find my vehicle VIN with the proper owner information in their system. …”
