Check engine light
Anyone know what an MPH caution is for a check engine light? Car runs okay but my check engine light is on. The chech engine light has gone out twice but came back no less than two days after it went out.

You should get the code pulled
It could be something as stupid as a brief misfire or something more serious. I would get it checked out sooner rather than later, but if its flickering on and off you should be ok driving it for the time being...just not at like 120mph

Are you referring to the idiot light on the dash or the "MPH" warning in the DIS?
If it's the latter (more specifically, the letters "MPH" inside a red circle), then you've accidentally set the speed limit warning (e.g. you set a specific speed, and whenever you go over it beeps & gives you a warning in the DIS) and exceeded that limit. RTFM to find out how to remove that limit.
