I have a similar situation. I have a 2012 Volt with 195k total miles. Of those, about 125k is ICE. Oil pump failed and the engine needs to be replaced. I'm trying to figure out what to do now. I feel my options are pretty limited and my wait in MO for a Bolt EV is end of the year. I do think it's funny the ICE is what failed while I still mostly have the same range of a new one on electric. At least I can drive it close to home!
Disintegrated Oil Pump
The oil pump in my 2012 Volt disintegrated suddenly without any prior warning just one month out of power train warranty.
GM is not helping me to fix this because I bought the car pre-owned (so, no Good Will warranty even though I have maintained the car as recommended and the prior owner's maintenance records are in the glove box. I spoke with GM customer service and the Electric Vehicle team and all said the same as the dealer service manager: I am out of luck as per GM policy).
So, I spent $2500 to have the oil pump replaced (at a Chevy dealer) and the car ran fine for about a week. Now it's making a tapping/clicking noise and the Knock Sensor error (P0324) has triggered the CEL.
Anyone else have an oil pump disintegrate? I am planning to file a report with the NHTSA so that there is some oversight. But, I am curious if there are any other cases of oil pumps disintegrating like the one in my car did.
Thoughts on what the tapping might be now? It is full of oil and the oil is clean.
TIA!

Sorry to hear about the oil pump failure. If this was a frequent issue this would have been reported on this site by now, but this hasn't been the case. Since you bought used, the other unknown portion of the equation is what the prior owner had done, and if they were using the correct fuel and fluids. This is why I personally won't buy used. Most of the time your'e okay however occasionally you're unlucky.
One should never run the engine without oil pressure. The correct response is to pull over, turn off the engine, and call for a tow. Once you do the engine is toast.

PUMP KIT. Engine Oil Pump Part Number: 55574770 PUMP KIT,OIL.
Considering the oil pump repair kit for the Gen1s is @$100, wonder if preventative replacing the oil pump with this kit for high-mileage Volts would be in order?
I guess it depends on how hard the replacement procedure is. Anyone willing to post the steps from the service manual?

Special Oil Pump Helps Chevrolet Cruze Conserve Fuel
Something tells me this wouldn't be a simple DIY!
Seems like of all the hundreds of parts to break or malfunction in a modern gasoline, or diesel engine, the oil pump is perhaps the most durable as it is for the most part submerged or lubricated with motor oil. I wonder if the same oil pump design has continued with the Volt's 2016-17 model with the 1.5 engine?
Most modern engines have switched over to this rotary vane design (over older gerotor type pumps) as they are more controllable and reduce parasitic mechanical loads. (better mpg) Most all automatic transmissions have been using this type of pump for over 50 years.Seems like of all the hundreds of parts to break or malfunction in a modern gasoline, or diesel engine, the oil pump is perhaps the most durable as it is for the most part submerged or lubricated with motor oil.

I understand the frustration, but don't see how taking a big hit on trade value and then buying another vehicle is cheaper than just fixing the one you have. Good luck, though!
find an engine here and have a local mechanic put it in,,plenty of low mileage engines.I have a similar situation. I have a 2012 Volt with 195k total miles. Of those, about 125k is ICE.

I just wanted to bump this thread with the thought that replacing the whole engine with a brand new one might be cost effective, depending on the mileage of a damaged engine. Here is one costing $3552.12 with a core charge of $300. Of course, additional labor and shipping costs would be on top of that. I don't know how much that would be. But, it's food for thought.

Very interesting; thank you for posting and reviving this now over 2 year old thread...Even with additional costs, it might be a suitable option in case of one of these rare but catastrophic engine component failures.I just wanted to bump this thread with the thought that replacing the whole engine with a brand new one might be cost effective, depending on the mileage of a damaged engine.

I wonder whatever happened to the OP's damaged Volt. Did it get repaired or traded away?

Its easy finding good low mileage used engines for these cars, there is a big auto breaker near me that has several, one is 16k miles and only $350.
Not worth spending the money on a new engine for the Gen 1 volt now. Its part of what makes them such a great deal now, really low cost replacement parts!
