My CR-Z just had the check engine light come on (steady) and now it won't change modes. Standard only, no Sport or Eco. I think it's just that it wants and oil change. It's been warning and now it says do it now, oil life down to 5%. Seems when that came on I can no longer get to sport mode. All else seems fine. I'm scheduled with the mechanic in a couple days. Does it just refuse to change modes anytime the check engine is on?
