My Certified MDX has worn out tires. will Acura help?

Hi,
I am new to this forum.pls. excuse me if there are any mistakes.
I recently bought a certified MDX on 4/29th(3 days ago) from an Acura dealer.
after getting car home, yesterrday I checked tire tread with guage bought at autozone. tread is 4/32nds, 3/32nds. only one tire has 5/32nds.
If I contact Acura, will I get any help with these tires? pls. suggestion.

Thanks in advance.
