3900 miles. Got the Malfunction Indicator Lamp (MIL) on, solid (not blinking). Looks like this:

Took it into the dealer and they referenced TSB 2053040/2 Checking DTC - Cleaning DTC - Adapt the Throttle Body.

Code P050A00 (cold start idle air control performance) was stored.
Technical Background (on my paperwork from the dealer):
On some vehicles, it is possible the throttle body is unable to lower engine idle during catalyst warm up. This is caused by incorrect basic settings for the throttle body stored in the ECM. This is NOT due to a component defect.

So, I take it that they clear a setting in the ECM and then perform some test/running/driving procedure and the ECM stores a new/different setting. Seems simple enough.
