Low coolant.

I added my own coolant and then I had to bring in the Volt to have the light reset. My preference is to have it touched as little as possible. The dealer wanted to do a pressure test. Why would I want my system under pressure and risk starting a leak where there was none. I told the mechanic to reset the light and I will be on my way. He thinks there were air bubbles that just settled after 10k miles and it should never happen again. I am keeping an eye on the fluid levels anyway. So far they have not moved after a month, so I think I am fine for another 10k miles when I think I will have to add some more coolant, unless it really was air bubbles.
I am just posting this to let others know my opinion on this, but it is your decision whether you want your car messed with.

    pressure testing the battery system standard procedure when coolant level is low, and is to protect you against the possibility of recurrence leaving you stranded.

    Yes, I figure that if I keep checking it and it never goes down or takes 10k miles before it does, then I should be ok.
    Actually I think the pressure test is more of a safety thing. They do not want liquids getting in contact with the battery. A low battery coolant will just turn you over to gas, like what happened to me. I think?
    The mechanic said that they do not know where this fluid is going. So I have little confidence they would know with a pressure test. Either way, I do not think there is a problem. It is either air bubbles or it gets burned off faster when you drive mostly in electric mode. If I see the level dropping off sooner than 10k miles, then I would get a pressure test.
