Hello, I just bought a 2012 Chevy Volt,
I'm driving and all of a sudden the Propulsion Power Reduced, Engine Not Available warnings and yellow check engine symbol appears, plus sometimes I get hard time starting to move, I put in D and nothing happens, just the bubble that resembles my driving manners goes way up...

Dont know what to do, already changed the battery thats in the back to a new one (not the big one that stores the driving energy), biggest problem is that I'm from Lithuania and here we don't have a Chevy dealership, or even a service thats able to do that kind of diagnostics.

Check to see if the Battery TMS coolant level where it's supposed to be? I assume you have an Owners Manual? It will show you how to do that and exactly what kind of fluid you need to fill it.

You should get an OBD-II reader that plugs into a connector under the dashboard near the steering wheel. This will allow you to read any error codes from the car's self-diagnostics. If you had an OnStar subscription they can run a diagnostics report and tell you error codes also if you specifically ask for the code numbers. However, I don't know if you have access to OnStar. OBD-II is common to all cars sold in the USA but I'm not sure if it would typically be present in a European car. A local car mechanic might be able to use their OBD-II reader if you don't want to buy your own but they are cheap now and easy to buy on Amazon etc.

Once you have the code numbers you can post them here and people here who have Volt service manuals can lookup to see exactly what is wrong.

Thanks Jeff, today I will try to do the OBD-II reading and be back with some codes..

I think these codes are both somewhat vague and general codes rather than detailed and specific codes that usually also are reported with them. Perhaps you can try searching for additional codes.

In any case, the P0700 code is a general code indicating a problem related to the transmission. If you try searching Google with the search term "site:gm-volt.com P0700" you will find a bunch of threads discussing car problems that included this error code but you will see that there are additional codes that point to specific problems rather than this general error code. Still, reading some of these other threads may help give you some clues. I just quickly looked and the various problems ranged from wiring connector pins being not correctly inserted, bad grounding connections, to the need to replace the valve body control unit that is part of the transmission.

As I said, if you can somehow provoke and read more specific error codes that will help pin down the exact cause. With a more specific error code I can also look up more details on further diagnostic suggestions in my copy of the Volt service manual.

In your situation, it might be a good idea to buy your own service manual. It costs $200. The paper version is a 3 book set containing maybe 3,000 pages of information including illustrations of all of the parts in the car, descriptive and diagnostic suggestions for every possible error code, wiring diagrams, and detailed descriptions of how different components of the car function.

Here is the link to buy it. It is written by GM but published by a company that specializes in publishing service manuals:
