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.

I was driving on the highway and as I was entering an exit, I heard a loud bang like a shot gun blast. I was on my way back to work from lunch, so I pulled into my office's parking lot. I look at my vehicle's dash display screen to see if a tire had blown. I exited my vehicle and walked around, but didn't notice any damage. Later that afternoon on my way home I heard wind whistling in the vehicle, I checked my windows, but they were all closed. I then opened the sun screen and that is when I noticed a huge hole in the center of my sunroof. The center of the sunroof had blown out.

While descending a steep grade towing an 8,000lb travel trailer using appropriate hill descent braking techniques, an error message came on the dash indicating a trailer wiring, type, or connection fault. From this point forward, I had no trailer brakes and was left with truck brakes only. I got the truck/trailer combination to the bottom of the grade safely, however this could have been catastrophic for an inexperienced driver or in a different situation. Upon further investigation, this is a common problem with Toyota Tundra’s, and acknowledged by Toyota in TSB # T-SB-0036-19 issued on April 1, 2019. The dealer and Toyota Customer Service will not acknowledge this, and states it is something only covered under the 3 year warranty. My question for you, the NHTSA, is how would this not be considered a safety issue, when the issue comes on unexpectedly under less than ideal circumstances, especially when Toyota has acknowledged that there is a problem with their brake controller. This is a safety issue, not a warranty issue. Toyota will be held accountable for any injury or death caused by my vehicle in this situation.
