"Wow, this car really is quiet."

While that could be the response of someone new to riding in the Chevrolet Volt extended-range plug in hybrid, the fact is that Chevy parent General Motors is addressing an issue where the car's engine shuts down abruptly, a time when anyone would wish for a bit more noise.

There's a glitch in the software of some 2013 model-year Volts that may cause the car to unexpectedly shut down in the middle of a drive, Hybrid Cars notes, based on items posted on the GM-Volt message board. While steering and brakes remain functional, the powertrain shuts down and may force some drivers to wait as long as five minutes to restart the car.

As a result, GM is offering a free "service" at Chevy dealers that offers a free software upgrade and takes about an hour. GM isn't calling the situation a recall, and Hybrid Cars says no accidents have been reported as a result of the glitch. Still, it's a hiccup for a model whose sales have gained momentum recently. September marked the second straight month of record sales for the Volt, which sold 2,851 units, almost quadruple year-earlier figures.

      Sync needed updates, your computer needs updates...this sort of thing will be more and more common as time goes by. Everyone calm the eff down (I say this preemptively as no one has commented yet, but it is a volt article, so everyone is bound to start screaming.....

        The Tesla Model S is already getting updates, and we all know the saga with Fisker's continuous updates... This is to be expected as autos are more software and less hardware.

          3rd gen Priuses got software updates because they had a bug that caused them to just stop moving at highway speeds from time to time. It's bad to have bugs, but far worse if they are never fixed.

      This is a very complicated car, im surprised it didn't have more problems till it is on the market. Congrat to gm.

      It is interesting that this has happened. Some Volt owners would like '11 and '12 models to receive the same software upgrades that the '13 has. The consensus is that GM updates each model year separately and does not introduce "new problems" with updates across all model years. So likely problems may be isolated to one year. From a software point of view I can see why they want to limit upgrades. But it is frustrating that new model year cars get cool new software features. There may also be hardware changes in between model years that necessitates this too.

        You're talking about the EV HOLD MODE, right? I am curious if that requires hardware updates as well..

          They put the Hold mode right in with the other modes. How you select it is the same as Sport and MTN. I don't know if there is anything "complicated" or hardware related that would be an issue.

        I had to apologize once to everyone - I cannot remember the subject, but I assumed everyone would scream and they did not. Cool being wrong on stuff like that!
