NHTSA Complaint #11469256 — 2019 TOYOTA TUNDRA

A technical safety bulletin was issue for this issue (T-SB-0036-19). On a recent trip in the Great Smokey Mountains National Park, my wife and I were pulling a travel trailer with LED lights and noticed that the trailer disconnected warning come on. We thought it was a loose cable and pulled over to check the plug. We started home after our trip and had this occur several times on step grades. The scary issue is the lights continue to work indicating that it’s still connected, however when I checked the manual brake controller there were no brakes! There were no areas to pull over. Once we were able to pullover safely, we checked the connection again and it was still secure. This occurred again on I-40 as we approached and accident scene with sudden braking. Then it disappeared again. We made it safely home and I started researching the issue and found the bulletin. I took it to Toyota to complete but it’s still an optional bulletin. This is an enormous safety issue considering a 5400 pound truck capable of towing a 9200 pound trailer at highway speeds with no braking or access to the first step to stop trailer sway.
