engine maintenance mode

  1. EMM achieved, Yay!

    Care, Maintenance & Service - Chevy Volt
    I'm proud to have finally joined the Engine Maintenance Mode club. This is a great day. It means I'm not using gas anymore and the Volt had to fire up the gas engine for a few minutes to keep things working and maintained. For years I have seen posts by those complaining about EMM, but for me...

    Care, Maintenance & Service - Chevy Volt
    My 2016 had a humorous message pop up this morning indicating that the engine needed to run for 15 minutes since it hasn't been used enough. Hey, sure...no problem! What did surprise me, however, is that car continued to use the battery while the engine was running and drank down the normal...

  5. Got My First Engine Maintenance Mode...

    Chevy Volt Engineering and Design
    I used about one gallon since Thanksgiving so the engine maintenance mode ran for about 5 minutes using a tenth of a gallon. If it does this every 6 weeks, after a year, how does the entire tank get burned down? Does it run for much longer, anyone experience it running after a year on the...
