  1. First EMM on my 2017 Volt

    Generation 2 Volt (2016-2020)
    Well today was a small thrill. I just passed 700 miles on my new Volt and got to experience my first Engine Maintenance Mode. I wasn't sure what to expect, but it was fun watching the progress on the Info screen. My first thought was, 'Oh crap how long am I going to have to drive around and...

  2. EMM while parked, or while driving?

    Generation 1 Volt (2011-2015)
    Greetings, all! I believe my first ever Engine Maintenance Mode should be coming this Sunday (although, I actually think I'll be doing a lot of driving Friday/Saturday and might end up using the ICE before the 6-week mark--we'll see), and I just wanted to see what other people do with regard to...

  3. EMM/FMM and Electricity Generation

    Propulsion Systems - Chevy Volt
    I just had my first EMM since I've been using my OBD to monitor things. I was under the impression that EMM simply switched to gas mode to get things running, and otherwise normal operation, despite having battery left over. And that any unused power from the engine spinning the generator would...

  4. New car smell? Not!

    Chevy Volt General Discussion, News, and Events
    Just leased a new 2014 Volt last Friday night and took it for a shakeout ride the next day. At about the 40-mile mark, when the ICE kicked in, I began to notice an industrial, acrid odor (like a car fire). We were on the highway in stop-and-go traffic (on the Cross Bronx Expressway headed to the...

  5. Discrepancy in gas used for Engine Maintenance Mode

    Generation 1 Volt (2011-2015)
    Today I had Engine Maintenance Mode (EMM) #16. I use my VoltStats data to calculate the amount of gasoline used by dividing total miles by MPG. From my last VoltStats update before the EMM I had 42,111.58 miles with 3,036.37 MPG which works out to 13.869 gallons. According to my Volt I used...

  6. I had to do it (EMM)

    Generation 1 Volt (2011-2015)
    So, after delaying Engine Maintenance Mode (EMM) four times Saturday night, I did it Sunday and it took 4 minutes and 3 seconds. I planned it so that I was on the freeway. It only ran for 0.6km (0.37 miles) and used 0.12 liters (0.03 gal) of gas. I'm at 92% EV at 471 MPG (lifetime). :cool: I...

  7. How often and under what circumstances does the Volt force gas burning in EMM or FMM?

    Mechanical Systems - Chevy Volt
    I'm a newbie and am certain this has been previously discussed but I couldn't find it in one thread on this forum. If the Volt is driven in EV mode exclusively, how often does it burn gas in engine maintenance mode (EMM) to keep the ICE happy? and is there any warning? I think I read that if...
