Yeah, navy federal pulled trans union for my recent model Y purchase too. I only know because of the disclosure they mail you after the application. For me, Trans Union has always been the lowest of my 3 scores. It doesnt matter much to me because all of them are over 800, but my trans union is like 809, and the other two this month are 830-840.
Navy federal isnt "Tesla" though, which is what this thread was originally asking. For credit freeze purposes, its best to temporarily unlock all 3 right before you apply, for a few days.
