Boy, am I frustrated! My car was one day short of being mine for a month and I'm driving home from work...and <bing> on comes the check engine light! It was -12 outside, but this car was tested in Northern Canada right? I charge at work (240V) and at home (240V). Not one issue until that evening.

I did get an error on the Onstar app when I tried to preheat the car from the office (error message 202) before all this happened. So, anyway I started it when I got to the lot and noticed the check engine light about 2 miles into my 30 mile drive home.

Called Onstar and they said I needed to get the car into service within the next seven days. I was told it was an I.C.E.issue (code P2097). The car seems to run fine, but it will not start remotely, while plugged in.. I'm dropping it off for service tomorrow morning.

It's hard to find new roads, while it's sitting on a dealer's lift!

Bumming in Chicago!:(

Strange, I can't find much information on P2097 here:
http://service.gm.com/gmspo/mode6/pdf/2011/11OBDG01 HYBRID Diagnostics.pdf

Be careful about the causation there, e.g. that the lack of a remote start is related. Unfortunately, OnStar is pretty unreliable with remote starts. I've found that, for me, it works well if I hit remote start on my phone and wait for the popup to say "Sending Remote Start Request" and then disappear (on the iPhone). At that point, the start request has been relayed to the OnStar server, and usually all is good from there.

Please keep us updated, as I believe this is a new error code to the forum. Hopefully this will be the only error you'll ever see. Most of us may have had an error or two pop up, but otherwise have had trouble-free experiences for years :)

I got a CEL the first day I had my Volt after plugging in the a public charger that had some voltage issue. OnStar told me the same thing" within 7 days. In others words, a somewhat minor issue. Still, it freaked me out. My advice, roll with it and don't stress. Stuff can happen. That's what the warranty is for.

My Check Engine light came on last night on my way home at -20F. Same as OP reported - car would not remote start this morning using either fob or myVolt.com application. I called OnStar on my way to work and they said the code indicated "reduced engine power" could result and was related to the fuel system. Whatever it was I had OnStar hand me off to the service dealer and scheduled an appointment for tomorrow morning.

Our high temperature yesterday was -14F and the low was -24F. People had problems with all makes and models of cars where I work. At any one time during the day one out of every five cars in the parking lot was running. My son's 2005 Scion wouldn't start even with a strong battery - I spent three hours at -18F trying everything I could think of. We went to check on it today before picking up a tow strap and tow vehicle at home to haul it home. it was -4F at the time but had gotten as high as +4F with sunshine during the day. Remarkably it started right up.

Through all this my 2013 Volt was issue free until the check engine light came on last night. I had gone out for lunch and driven it once during the day long enough for the ICE to become warm. I remote started it three hours later but another three hours in -18F was enough to effect the battery. It took only three miles of driving with the ICE to get my full electric range back.

The upside of all this cold is that it will kill off a large population of the Emerald Ash Borer. A few days of extreme cold, though a pain, is worth it for saving the Ash trees in my part of the country. Let's just not do this every winter.

If the golf was so great in Minnesota I'd move back to Arizona tomorrow. Then I could suffer through +123F days like I did in 1989.

Take the 12V battery out of the car and let it warm up a few hours inside, Mike? Does wonders for my cars and John Deere snow blower.

ECM = engine control module, right? Something to do with the heated oxygen sensors, but let a trained mechanic diagnose it, not me.

Yea I was going down that road and got everything disconnected but could not physically get the battery out of its spot. It's a tight fit on a warm day but with gloves and parka couldn't get it. Finally capitulated after 20-30 minutes of just trying to get it lifted out and hooked it back up.

But the battery was cranking pretty good. I figured like you suggested it just needed some heat in it (which is why I was trying to take it out) so I resorted to turning on everything electrical in the car while I had it jumpered to the 12V battery in the Volt. I wanted that thing to have as much current going through it as possible just to generate some heat. And it definitely helped. It came so close to starting but it seemed like it was fuel or ignition limited. In any event we got it started today and it is in my +15F garage tonight next to the John Deere X500 with the 44 inch snowblower. My Volt is outside connected to the charger.

We have 24 more hours of this silly cold and then temperatures are climbing way above zero for the next week. Hurray!!!

.. water/condensate in the fuel .. a fuel line freeze up ..? I've seen it happen on some other cars before.
you are a master of understatement- the Volt does a great job of keeping new moisture out of fuel, but your local gas station and storage farm, probably not so good. Tiny, Tiny bits of ice can affect lots of fuel system componentss, as can condensate on the heated O2 sensors before they heat up......

I've been thinking along the same lines as you and Neromanceres. It's part of driving a Volt not to fill it up very often, and I was worried about the gas I put in on a mild day in October, so yesterday I topped it off. That is a normal ICE under the hood and it would be subject to all the normal cold weather issues.

Through all this mine's been parked outside plugged in, and there's been no problem at all apart from being encased in ice during the pre-Christmas storm.

The x500 is a very nice machine, Mike. Mine is one of its 34 year old predecessors, also with steel frame, hydrostatic transmission, hydraulic lift. Sadly, no V-Twin. However, I keep my Deere outside and the Volt inside, lol.

Well the local Chevy dealer has my car now.. I'm the temporary "owner" of a huge Chevy Malibu. It's big! And it heats the cabin VERY well! Anyway the technician said they haven't seen many Volts come in for service and he's not sure why the CEL came on. They'll call me tomorrow with the news.

I'll post the results when I find out. Stay tuned...

I picked up my car today. No more CEL. I was told the emission sensor initially said there was a problem, but the technician didn't find anything wrong with it. They asked me what octane gas did I put in the car? I explained that I have never put gas in the car. That gas came from the dealership. (I bought the car from another dealer that is farther away from my home.). We'll see if the problem resurfaces. I stopped and filled it up with 93 octane from Mobil since it was pretty low in gas anyway.

I don't have hydraulics but I'm not sure I miss it. The X500 is easy to operate without power steering or hydraulic attachments. I had a coil fail on the Kawasaki twin at 10 hours under warranty. Otherwise the X500 has been reliable for its 213 hours.

Some of the older JD's are better than the new ones. Sounds like you have a keeper.

I've been getting the CEL when my gas is very close to empty. I fill the tank half full like I usually do and it goes away in a few hours. It could be related to our cold Winter temperatures. If you read the manual, a CEL doesn't seem to be a big deal. It can indicate a loose gas cap or cheap gas. What the manual says is fill up the tank with quality gas, be sure your gas cap is tight, and drive it for a few days. If the CEL stays on for an extended period, it may need service. I wonder if somebody could clarify what we should do in case of a CEL.

This sounds like the same problem my Volt exhibited but the technician who was fairly experienced called GM for assistance. Eventually they figured out that one of the gaskets between the catalytic converter and exhaust pipe was leaking causing the post-catalytic sensor to report values that should not have been possible. They asked me the same question about using Premium. I always use Premium. It took them about three hours to diagnose the problem and replace the gasket.

I did not purchase my Volt at this dealer but I had taken a test drive at this dealership. While taking the test drive the "Product Specialist" (i.e. sales person) talked a bit about how their Volt certified mechanic was especially passionate about the Volt and kept tabs the movement of every new and used unit on the lot. By chance I got to meet him.

It turns out that my CEL turned off on its own between parking it Tuesday night and Wednesday morning when I attempted a remote start that succeeded. My appointment at the dealership was at 8:30am and since I had a flakey key fob I decided I would go ahead and have the Volt checked out anyway and get the fob checked out too.

The service advisor made an attempt at explaining the gasket issue and turned the car over to me. When I opened the rear hatch to put in my laptop the rear floor was open and there was a battery charger hooked to the 12V (but obviously unplugged). Since I didn't need a free $150 professional grade battery charger I went back in and told them they had forgotten something. John the Volt Tech came out, apologized profusely, and then spent 10 minutes explaining in exact detail his troubleshooting, conversation with GM tech support, and subsequent repair. He had the charger on the 12V to keep from draining it because the troubleshooting took so long and was interrupted as he was finishing up. No harm no foul. His passion for the car and its level of complexity was obvious. He made a point of telling me not to hesitate to call and ask for him if I ever observed any issues with the Volt.

I left the dealership feeling satisfied. Village Chevrolet in Wayzata MN earned a new service customer with my first visit.

I'm not going to ding Chevrolet for the leaky gasket. It was -20F when the failure was detected. At that temperature I'll excuse any nuisance failure. It could be that cold soaking the entire day at -17F contributed to the failure.

I just got that code on the way home today Volt was plugged in for about 8 hours ironically enough i am hoping it just goes away but on the ironic plus side at -20 Celc it only burned half a liter so the fuel code causes the ice to burn less fuel lol ok for now but might suck with reduced power on a road trip :p

The ERDT did still run just ran for about half as long as normal.

Got P2097 today as well. It has been very cold in Toronto area the past few days, -24C (-11F). We only fill with top-tier gas stations and exclusively fill with 91 octane. My wife and daughter reported strong exhaust fumes during early morning starts a couple of weeks ago and again today. We have a car port that is open on 3 sides. They remote start on very cold days. We are always plugged into our L2 EVSE, yet my wife reports the ICE started to run and has on many occasions. Nobody has messed with the car Config and I have the Volt set to *NOT* have engine assisted heating when plugged in.

I marched out and checked the settings and sure enough, engine assisted heating was Enabled and furthermore the threshold was set to when cold (I have always had it set to 'when very cold'). This is now the second confirmed occasion where these two specific settings have self-reset to defaults after having configured them previously myself. Nobody (wife or daughter) touches the vehicle config, they don't even know it exists. What gives with settings reset to defaults?

The bitter cold ambient temp and P2097 seem to be related. Exhaust gasket was previously mentioned in this thread, ties in with fumes in cabin. Might be something to keep an eye on if this is a trend.
