Any idea what the issue is?

Couple things to be aware of or think about.
1) The AIP system doesn't engage under 41F anyway, so if bypass failed, the system wouldn't run anyway if you are cold starting sub 41F.(yet to have a known failure in the field BTW).
2) The cold weather glitch isnt a repeatable "normal" thing. Its very rare. So I wouldn't assume because of living in MA and it hasn't happened yet, doesn't mean it won't.....and then may never happen again(or at least be very rare). Do you have a OBD2 scanner? Not to clog up this thread but with a quick check you can look at IAT(Intak air temp) and determine of bypass is working. Email me for details if you want to track it down.
3) Rodents (it happens)
4) Bad MAF sensor. (OBD2 can check this as well)
