I’m looking at buying a used volt. However, I’ve been reading a lot about the BECM issue for a lot of the 2017-2018 models, and those are the models I’ve been looking at getting….

I’ve read about the special warranty that covers this issue, but I’m not sure about the specifics of how it works.

I live in NC, (which I don’t believe is a CARB state). On local dealership websites, I can’t seem to look up any information on the cars here that specify if I have the warranty or not. I can see the carfax on them, and some say they were originally sold in a CARB state like Maryland. But the warranty section on carfax just says “no data”.

I’ve been looking into cars near me however, and I found one in VA that has a vehicle information page on the website. I can see under “applicable warranties” in includes:

Emission limited warranty - end date (09/29/33).

Voltec component warranty - end date (09/29/26).

Emission select state component ltd wty - end date (09/29/33).

PZEV emission limited warranty - end date (09/29/33).

If I buy this vehicle and bring it to where I live in NC, will I still have the warranties? Or will they be voided since I don’t live in a CARB state? The warranty status is a pretty large determiner of whether I buy this car or not since I can’t afford a $15k BECM replacement.

2018 Volt Premier. 133k miles

Anything I should be aware of?

Thanks for your advice- college student here thinking of getting a '14 Volt w/ 98k miles for $5500.

Seems like a great deal and they said it still gets 40 miles per charge. Any concerns I should be aware of with it being a 10 year old car? How many more miles of life does this thing have? Thanks!

So my Gen 2 has been in with the dealer since September second. Vehicle had a failed charging attempt and a litany of codes normally pointing towards a 12v issue (expected since it has original 12v battery.) volt has had becm and 2 hv cell groups under warranty. I asked dealership to replace 12v and reset hv codes but was instructed I could not leave the dealership as my car has a voltage spread on 3 cells after the charge event and they need to replace the entire hv battery. Part delay has now gone from December to march to July. Any thoughts on how I can get this up and running. It is our only vehicle and while we have a loaner from Chevrolet we can only put on 2k miles at a time and cannot leave our metropolitan area. I have to take my daughter to the Ryan ability lab in Chicago multiple times per year and have to rent a vehicle every time. Just looking for thoughts. I have a vcxnano and almost want to pay out of pocket to replace 12v battery and reset hv codes so I can have my car back. I also offered to pay for a salvage hv pack and becm reprogram but they said I would void any warranty by doing so. We requested a buyback due to part delay and they called us on the last day of warranty saying they denied request and as we were now outside warranty we could not peruse any other remedy

Hello everyone, had a weird thing happen yesterday.. 2017 Volt Premier no ACC

Driving along with about 2/3 battery charge and all of a sudden the engine kicks on and stops using the battery. Also the switch over was abrupt and not smooth like usual. I was unable to put it back in normal (EV) mode, it just ignored the switch. This happened for about 3 min and then switched back to EV automatically. Again very abruptly and not smooth as usual. No further issues or events, no idiot lights or warnings (it is time to change my oil).

It's not maintenance mode as I make about a 60 mile trip every weekend which is about 40 miles of gas usage. No chance I hit the modes button as it is behind my cup holder glasses case.

1st time this has happened, I am curious if anyone knows things I should check.

I was changing my oil and noticed that the reservoir for the power electronics coolant was completely empty. I have no idea how long this has been empty and the can has been running completely normally. I refilled the reservoir and will be checking the level regularly to see if I can find a leak. I am wondering if I need to get the coolant line flushed.

On a side note, I am not sure if this is at all related, over the summer my car had been throwing p2135 codes randomly and going into reduced propulsion mode. I would clear the code and it would come back sometimes immediately or not for a week or two. I replaced the accelerator pedal, but the code eventually came back. I noticed that the code appeared only on the hottest of days. Since it has cooled off I have not seen the code in months. I am now wondering if it had something to do with the lack of coolant.

Thanks to all who helped me evaluate the Bolt as my possible first EV. I've ended up leasing a 2023 VW iD4 Pro, as it was a deal I couldn't refuse. As such, I'll be departing this sub. You can find me over at VW iD4 Owners if any of you decide to check them out. PEACE!

Been doing a lot of research and I love the volt. The way it’s primarily an EV with gas powered range extender is absolutely amazing tech. Way better than pure EV vehicles around today. I’m really looking to getting one, but the average price from places like CarMax or Carvana are about $12-15k at the minimum w/ 70k+ miles… is that a good deal?

I have seen others - at side of the road type of car yards, with way over 150k miles for under 10k, but honestly, I don’t want this car just for a few years. I love the design of this car and the tech, so I would really like to drive this for years. Is getting from carvana/carmax at those higher prices worth it?

Is that

So, the fb volt page declined to post my post because I questioned weather Gen 2 used heat pump for cabin heating. I’ve spent hours sitting in new volt investigating what’s what and I absolutely hear the elec compressor come on when heat set to “eco”, and warm air then blows from vents. It also seems to have a resistance element within the air box, used when heat set to “max”.

Now I want a definitive answer, have checked interwebs, no clear result.

Here’s the declined post…

Wrapping my head around the Volt cooling systems and hvac. Fascinating reading…

As a side note, seems Gen 1 uses resistance heat in ICE coolant loop to heat cabin. Gen 2 seems to have heat pump and resistance heating element built into hvac air box.

My first gen gives me a notification when I have a bulb out. Does the 2nd gen not have this feature??? A man pulled to tell me my brake light is out.

Hello!

Does the 2014 Chevy Volt support Bluetooth music steaming? Asking because my 2013 GMC Sierra supports Bluetooth calls but not music 🙄 I just want to listen to music via Bluetooth while driving! Lol.

Thanks in advance!

They are the exact same car. They are both GM branded junk so tell me comments what’s the difference between both of them? (;

Hi, 2 days ago I bought a 2011 Volt with 96k miles on it. During the test drive and drive home it was using strictly battery and not showing any signs of the issue I’m having now. During the two mentions drives none of it was highways driving (honestly should have tested that I know) but on my drive to to work and back yesterday and the drive to work today I’ve noticed that while on the highway, during the acceleration process, it will switch to gas, even though I have a full battery. I’ve noticed it stays on gas for a couple miles then switches back to battery, it’ll sometimes go back and forth if I’m in a situation where I have to slow down a decent amount and get back up to speed. Just wondering if this is an issue I should address, or if due to the high speeds and acceleration process of the highway of that is just a feature built into the Volt to maintain battery? I will say I do live in a Michigan and we’re having a cold winter, so that could be an issue. Just a little disappointed as my drive to work and back is in range to never have to use the gas if the batter stays in tact the whole time, and I was pretty excited about (was a main selling point)

Thank you for any feedback!

Thought they'd left off 100,000 miles! Out in VA, must've just lived in the garage.

After leaving us stranded on the interstate and being towed, the dealership finally got back to us and claims the issue is a fouled plug. They want $500 to replace all 4. All signs pointed to the BECM, but they claim that code wasn’t present. What are the communities thoughts?

We got this message after the 12v died on our 2014 volt (133k miles). We haven't driven it in a few weeks as we had some vacation time off and just failed to run it. The car went into anti theft mode which happened once before when the 12v died. Now that we got it charged we got the SHVCS error message. I've been combing the sub here regarding the error. We noticed coolant is low so we were planning on topping it off but I just noticed some people recommend a coolant flush. Which is better?? I don't know if it's ever been flushed before so it probably hasn't.

I've really loved this car, but we decided to upgrade with the risk of the EV tax credit disappearing. We got a 2025 Equinox EV.

Car is in great shape inside and out (there's minor cosmetic damage to the front from an inconsiderate driver in a parking lot...). Heated leather seats, leather wrapped steering wheel. Still gets up to ~30 miles of range (about 9kwh) before the gas engine kicks on. In the last 5 years of ownership, I've averaged 80+ miles per gallon, as long as it gets charged daily.

Color is Viridian Joule and it has 157k miles on it.

I even have a spare tire I got for it. I have 2 volt level 1 chargers and could also include a level 2 charger possibly. It also has an 1500w inverter wired in to the 12v battery. I'll probably remove that, but I'd keep it in if the buyer is interested.

I'm listing it for $5500 obo.

My check engine light turned on and I read the OBDII over Torque. I got a P103A code, which on google appears to vary by make/model, but I think it is "O2 Sensor Slow Response - Rich to Lean (Bank 1 Sensor 2)"

Does anyone know what the code means for a 2014 Volt? Any tips on solving?

I've been running on gas for the last 8 months. I replaced my O2 sensors and spark plugs 3 months ago. I ordered some new fuel injectors; I heard that they could be clogged and mess with the fuel algorithm. I think the CAT could be the next thing to try.

Chevy Volt 2014. I can hear a clanking sound around the trunk area nearby the right rear wheel. It sounds like a plastic thingy banging the metal car skin or something. Had my car checked by a mechanic, they said everything looks okay and that it looks like a well taken cared car for a 2014 volt.

So, quick question. Ever encountered something like this? If so, can you provide details regarding the problem and how you fixed it? Thanks

Hi! My 2015 volt threw an ABS code, took it to dealer and its the dreaded ebcm defect for which the part is discontinued. Lucky i am in CA and its under 10 yr warranty (the car has 56k miles on it and is otherwise an awesome car). So sad that it is now undrivable.

Gm offered a repurchase under CA lemon law. Anyhow, the paperwork came in and the price breakdown is:

Total sales price was $34.5k

• $4.5k for manufacture rebate
• $14.7k for mileage

= $15.3k repurchase price.

I did the math using 120k miles life formula and got -14k for usage (56/120 =0.47%) * $30k

So its about $700 off. Should I get a lawyer to check this or does this look about right? Is it the norm to take out the manufacturers rebate?

Hello, Volt lovers! I've wanted one of these since middle school, and now that I have a big boy job, I'm trying to get my hands on one. Basically my question is: what's the deal with this battery control module? Is the 2017 model more prone to the failure than the 2018 or 2019? If so, is it worth getting a 2018-19 to reduce the risk of being stranded somewhere? Any advice to a prospective buyer?

Thanks in advance!!!! ⚡

Noticed these two odd lug nuts, which I do not ever recall seeing before. At first glance, from a distance, they looked like locking lug nuts which the special “key” to remove them. Looked all throughout the Volt and could not locate such a tool (which, if anywhere, would be located below the hatchback floor). Anyone know if the Volt was originally equipped with one locking lug nut for each wheel? In any case, I have a feeling I’ll be returning to the dealership for them to make it right. Thanks!

How does this look? Unfortunately Mygreenvolt isn't available for my phone running Android 15, so I used Voltage instead. Long story short I'm not 100% sure what good and bad are, other than the delta between high and low voltage shouldn't be huge (and it doesn't look to be). Additionally, do you guys know how it's measuring the 70% capacity? Is it from the original 16.5kWh or the available 10.5kWh? For reference, back in August/September, I was still getting ~10.5kWh from a full charge but over the last few months I only get around 8.8kWh. I know that EVs lose efficiency in the winter, but is less capacity normal? Thanks for any advice you guys can give!
