Yup my LBS have said Trek have not really been open to what is going on with the bike and have said they want to take the components apart from the bike. However I have told them I am very reluctant given that I have only used it a couple of times and also with the money spent etc.Hope they fix it quick for you, i was told if something like this happend they would likely replace the bike if it could not be fixed quickly.
I guess this is an early adopter risk for us.
I have uploaded a video with the warning error on the TQ screen which has now made the fuel exe useless. My LBS has said they have run out of options to fix it however they need to wait for Trek to give them the go ahead to replace it.
This is the link to the warning error below
