Same thing happened to me just a few hours ago. Car has been running fine with no issues, was driving back home and went to run on my headlights than wam (Check breaking system, Check ABS, Check VSA, Check power steering). Pulled into a local shopping plaza and restarted my car about three times, nothing.
Figured I can make it home and hopefully nothing will happen, pulled out of the plaza and all warning indicators and i-Mid warnings went away after 30 seconds or so of driving.
I have HIDs and the Injen CAI. Have had both for a good 7-8 months now with no issues until today.
