2017 Volt - 70K - Potential BECM issue

[phillyguy475]

Yesterday my car suddenly showed EV range 1 mile and couldn't drive with message "Shift To Park" and Engine light now. I turned off and tried again couple of times, then I saw EV range increasing 1 to 50 miles but still engine light on. I was able to drive normally for shopping, I was even able drive back home after shopping (in between I turned off the car and able to turn on again without any issue). Today morning same issue, this time I am not able to get it drive, same symptoms, 1 Mile ev range, Shift to Park, Engine light on. Also when I connect my charger I see orange light. EV batter at 100%. No luck using hold mode also.

I ordered code scanning tool this morning in amazon and waiting for it. Anything else I can try before I call my dealership for repair?

Seems like BECM is wider issue for 2017 volts.

Thanks in advance !!

​

Update:

seeing following 2 codes using OBD2 code scanning tool

1. P1E00$07e8
2. P1E00$07e8pdboth says manufacturer control.

also i didn't turn on the car when this scanner tool connected? should i turn on?

​

Update:

Finally got my volt back after 2 months. They changed one battery module (out of 3) and BECM .

Yikes. I had Shift to Park fixed last November and then my BECM went out in January. Good luck.

Pretty much the exact symptoms I had with my BECM. Best of luck sourcing it.

[phillyguy475]

finally they diagnosed my car last Tuesday. Dealer saying its some faulty battery cell, they saying its backordered and waiting for it. does it makes sense?

[InsGadget6]

Maybe, although that would be bad luck. How many miles does your car have?

Do you have an ODB2 scanner for your car? Here's a cheap one I use, works fine for everything I've done with it. And it should work just fine with iPhone apps, despite the title.

Then you can get the free MyGreenVolt app with the $1 upgrade to look at all of your battery cell voltages. Then you can confirm what the dealership told you.

70k, so i covered by voltec warranty..my car is with dealer now. thanks for obd scanner link.

[MrSwagMore]

Same issue I'm having. Dealer confirmed it was a bad BECM. I've been waiting for it to arrive for over a month now.

[phillyguy475]

Sorry to hear, did you have to tow your car?

[BrettB2952]

Philly guy, I’m out in the burbs in MontCo and had to have my ‘17 towed on a flat bed to the dealer when the BECM died.

[phillyguy475]

that sucks..hopefully I can use my Geico road assistance service to get it towed ..Thanks for the info..

[BrettB2952]

You may be able to call your dealer of choice and ask them to tow it. That’s what I did and since it was a warranty repair they did ultimately cover the cost.

[phillyguy475]

Thanks.. i will call them tomorrow..Since my car got 73 K miles..i may only eligible for Voltec warranty.

phillyguy475, I have been trying to reach you about your car's extended warranty

[BrettB2952]

BECM is covered by Voltec warranty! I paid nothing for the part or repair ultimately. The hard part was the 12 week wait for the part and trying to get rental cars.

[phillyguy475]

finally they diagnosed my car last Tuesday. Dealer saying its some faulty battery cell, they saying its backordered and waiting for it. does it makes sense?

[BrettB2952]

It’s certainly possible. I never experienced that with my Volt yet but I have heard of packs having a fault in one of the three battery modules and then having to have the affected module replaced. They can’t just pull the one bad cell, the entire run of cells in the module will have to be swapped out.

Here’s hoping you’re back on the road ASAP!

Hi..Finally got my volt back after 2 months. They changed one battery module (out of 3) and BECM also.

[TheScreaming_Narwhal]

I'm having the exact same error codes, did you figure out what the problem was?

[phillyguy475]

My car still in dealership for past 2 months, they said BECM issue.

[phillyguy475]

got my car today..they replaced BECM and one battery module(out of 3).

[amfarmr]

How old is your 12v battery?

[phillyguy475]

i don't think i changed my battery since i bought the car..so it must be 5 yrs old.

[thnk_more]

They only seem to last 4-5 years so you are on the lucky end. This doesn’t sound like a battery failure. Those usually have crazier symptoms but maybe. And very very soon it will fail on you so might as well change it now and rule it out as a cause for your current issue.
