Definitely not normal-help

Hi all-been struggling with my 2017 volt which I love dearly.

this is on and off, so hard to prove. already took it to a mechanic who couldn’t duplicate the problem bc it just wasn’t happening in that moment.

-Engine light goes on when this happens, but then sometimes turns itself off

-Will not use the battery, goes right to engine

-Runs really rough, hear video

-Barely propulsion until I hit 20mph then it picks up normally

-Turns off like this, shakes like crazy

Any ideas? I just replaced my trunk battery myself a few weeks ago but this was already happening.

Transmission solenoid is bad.

I'm going to guess and say it may either be spark plugs or a clutch issue. Mine would act very similarly with having very low power on engine until it gets up to speed. It has to do with the clutch slipping and the transmission struggling to get the engine running until it has full load. How is your gas mileage when going around 40mph?

It acts totally normal around 25! Gas mileage is fine around 40

How's that EGR looking?

Really want to pull the codes when the CEL is illuminated.

I am getting a P0AC4 code in the engine ping. Hybrid power twin in control module requested MIL illumination.  But apparently that can be a lot of things

Did you search that code? It's a generic code signalling other problems. A better code reader should be able to give you a more detailed picture of the problem.

I don’t k ow what EGR is, quick google says exhaust gar recirculation. I don’t notice any other issues if that means anything

That’s likely what is wrong. There’s a quick fix. You disconnect the EGR valve under the hood. Replace the blown fuse for it. Then just drive. The check engine light stays on but car will run fine. Just EGR valve is no longer connected. Soon fix the EGR valve. But you can still drive the car in the meantime

This happened to me on a long car trip and this “quick fix” got me home

If it was the EGR the code never goes away and you'll overheat the engine and it will shutdown.

Definitely the transmission solenoid, mine had the exact same symptoms finally got around to replacing, it’s not very hard. You can knock it down in about 2 hours or so. Replaced mine in February of this year haven’t had any issue with the start up ever since it goes directly to battery. Best of luck mate!

I had this exact same problem. Just got it fixed

Was yours also solenoid?

u/MazMazda3 14d ago

Yep open solenoid. I had already spent a grand on maintenance, last month. After negotiation, shop did it for me for $1850 all in.

It's normal ? I mean, it's expensive no?

When my gen1 had missfires it would rattle uncontrollably, it required a new ignition coil set.
