Reading your post it appears you gave tacit approval and from my experience there's no going back and undoing the inquires. Had a similar experience a few years ago
online and ended up with seven inquires. Very annoying but lesson learned, good thing they dropped off about a year or two later and had minimal effect on my scores. Oddly enough, I purchased a car from Infinti last year and they never pulled my credit and no inquires on my credit report.
Go sort your auto loan out with DCU or Penfed or one of the other copious and admittedly damned good auto lending CU's that pull EQ exclusively.
My personal opinion is virtually everyone should sort out financing before they head into the dealership, but your situation is easy to solve honestly: don't finance through the dealer in this case.
FWIW the dealer has absolutely zero control on who the lenders they submit their package to pull, and Ohio area, yeah that's old TU land from back in the day so I'm not surprised by your pull distribution. What's done is done as there isn't any recourse in this situation from a consumer protection or legal perspective, they had permissible purpose... so if you want the truck, go sort out the financing on your own with a lender, then walk back down there and tell them no with regards to financing.

Just to give a quick update. I went to PenFed and applied and was approved for the full amount!! They are sending me a check today to be delivered to me by Monday =) If I didnt need or want this truck so badly I would take the check up to them, show them, then leave lol.. Thanks all for the responses and the advise of going to PenFed!!!
