    Howdy,

    Got local Toyota to perform ECU flash as per TSB 0036-19 and it solved the problem on my 2019 Tundra. Finally towed today with no problems confirming it works in my case.

    I gather some dealers couldn't figure it out but it does exist and it did work in my case.

    See attached and show service department if they can't figure it out.

    Good luck!

    Greg

    Hi Greg, my 2018 Tundra is doing the same thing . Can you give me the name and location of your dealer so I can reference them when I take my truck in. For some reason i could not print your screen page. Thanks.

    Hi,

    Desert Toyota in Tucson performed the TSB for me

    I couldn't make it to the dealer who told me (Earnhardt in Mesa AZ) and first one I called argued that one does not exist! Refused to even consider it and insisted on leaving Tundra there all day so they can do numerous system checks!

    Called Desert Toyota who was less argumentative and in 5 minutes found the TSB, made an appt and in 2 hours was done (they did the the other recall radar deal too). Can take as little as 15 minutes but it relies on Toyota server and connection speed etc.

    All they need is the 0036-19 and that 19 may mean 2019 specific. Perhaps you can talk them into doing it on a 2018....
