Almost everything in new cars is controlled by some microprocessor (module) and they all run written "code" (software). "Bugs" in code can sometimes happen (written by humans and subject to "error").
When the right sequence of events happen unusual things can happen.
Stupid things like this example... "turning the air conditioning on high, then checking the trip odometer, and turning off the cruse control" (all controlled by same MPU) in that exact sequence...and the MPU outputs a very strange result... (doors lock, lights come on,fans run continuously)
Just by turning off the car and restarting it may have cleared the "bug" (reset the certain MPU) and it may NEVER return... OR ...you may have a problem beginning to show it's nasty head... I'm glad I'n not a car mechanic by trade!
That's why many times they "reprogram" the ECM (Engine Control Module) or BCM (Body Control Module) or TCM (Transmission Control Modules).
I'd keep an eye on the car and "if" other problems crop up DOCUMENT what you were doing at the time (speed of car,engine cold/hot,cruse on/off,....ect). It may help the KIA tech to pinpoint where the problem is...
Cars are not simple anymore with the fuel/economy, crash protection, air quality requirements, and ipod interfaces....Micro-computers won't go away and their presents will be seen and felt. It's not just "KIAs" They all have them.
The Forte has a known "bug" with hard shifting problems between 2nd and 3rd when the engine is first started. I don't know if they ever got that bug "squashed".
Your feedback to the dealer/KIA/service tech can sometimes REALLY help!
