My windows won’t go down. Electric door locks do not work. My radio doesn’t shut off when the door opens. Took the thing to the dealership and it started working again. Codes came up. But, when the tech went to work on it the codes were gone and they can not find the problem.

They can pull previous codes, in fact Advance Autoparts, O'Reilly's, Autozone can pull the codes for you retroactively. If that dealership isn't helpful try a different one.

Do you own a 2021 TB? Just checking, there have been a few folks come here with older gen models of these asking questions. You do not say what year you have. And this issue is a new one to this board. I don't think we have seen this type of issue with the new TB model.

I had this same problem and it wouldn’t duplicate when it was at the dealership. They did everything the bulletins said to do, but none of that worked. Then the last thing was to replace the ECM or ECU cannot remember which one for sure, but that fixed it.
