An email to Honda Atlas would be the best bet. Also mention the behaviour of dealership as Honda will be compelled to ask the dealership about the issue.
Traction Control can be turned on or off, there are protocols which can be configured, unless it's the problem with some on-board device or module, definitely a warranty issue. The dealership or Honda are both responsible to correct the issue.
They even change parts in warranty after a few months, this kind of ignorant behaviour is unacceptable. How else one would claim warranty?
Even if you have taken the delivery of vehicle, the traction control issue is their responsibility to solve, however, you may have to live with monogram issue as it's highly unlikely to get the correct one without dealership contacting Honda for a replacement.
