2016 Encore with code PO700 & U0100

[G-912779]

I purchase my buick from a Ford dealer ship used last year , about 2 weeks ago I got a check engine light , took it to autozone to have it checked and they said it has a lean bank 1 code.called my dealer to it looked at and it took almost 2 weeks to get it checked . They came back with a transmission module code ,.the ford dealership said they don't have any more they can do and suggested I take it to a buick dealer to have it looked at ? I was sold extended warranty thru Ford but it might not be covered,anyone have any suggestions about the codes I have ? Thanx

You'll want to double check but Ford actually has a pretty decent extended warranty for other auto makes. I had one on a 2003 Chevy Trailblazer, and my rear AC went out, the Chevy dealer I took it to had no problems getting it covered. That said, read your warranty and make a few calls to make sure.
