doc, do you have the 'elevated idle' enabled?

Not buying it. Just tried it on a 2015 yesterday. I don't know if you are repeating the button sequence correctly. Timed one with a "lock" followed by a 3 second "start", then another "lock" followed by another 3 second "start". It ran 20' 3"... just like the owner's manual said it would.

I wonder when they changed it?

This is from the 2011 OM: ( 'Q' and '/' being the remote buttons)

For example, if Q and then / are
pressed again after the vehicle
has been running for 5 minutes,
10 minutes are added, allowing
the engine to run for 15 minutes
