Turns out the starting problem I experienced wasn't unique to my 2010.
During that cold spell at least five 2010's in Fargo ND experienced the
identical problem. Toyota engineers were called-in. Their preliminary
determination suggests the 2010 suffers from two problems, the first
involving the engine running very rough when very cold, the second being a
poorly designed motor mount that results in the banging noise while the
engine is running rough. I've been advised to "live with it" until they
come up with a solution. The NWS forecasts -11F tomorrow morning and -18F
Thursday morning so it's rock and roll time Minnesota.
