The contact owns a 2018 Toyota Tundra. The contact stated that while driving at various speeds, both front headlights would intermittently go dim without warning. The contact then received a recall notice for NHTSA Campaign Number: 21V688000 (Exterior Lighting, Electrical System) however, the part to do the recall repair was not available. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 35,000. VIN tool confirms parts are not available.
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. …

This case results from the malfunctioning trailer brake ECU on 2018-2019 Tundras. There is a Toyota service bulletin T-SB-0036-19, which specifies an updated controller to replace the defective model. Part # : Original 89547-0C020 Update/replacement 89547-0C060 Toyota will not replace this defective part outside of the original warranty period despite the issuance of an updated replacement part. The service bulletin wasn't even issued until 4/19 possibly giving no recourse to owners whose warranty had tolled. The newer part number, suggests this was a dangerous defect that was upgraded. A review of this matter online details this problem has frequently occurred. The reason it's not more commonly reported is that a minority of Tundra owners tow trailers, and even fewer tow with electric brakes. …
I am having problems with the integrated brake controller constantly disconnecting when pulling any type of trailer. When ever I pull a trailer I never know when the controller will disconnect and I'll lose brakes on my trailer. This happens at any speed while towing. This seems to be a thing for 2018 tundras, as I've read about many other complants.
