My cold pressure is in the high 30s as well.

Maybe @Katech_Zach could chime in on this? ��

Good Morning,

As far as I know (the oil pump control strategy has changed year-to-year), the target hot oil pressure at idle is either 30, or 40 (depending on what you were just doing). I don't think there is ever a case where it is trying to target less than 30.

If it were me personally, I would start a GM case immediately (contact GM online via live chat), have them start a case, and bring it to a dealership to have them note the symptoms and temperatures you are seeing. Make GM aware of the issue prior to the warranty expiring, explain you want it addressed prior to expiration.

At least then, it is clear you are making an effort to get it fixed prior to your warranty expiring. If there is a case where you see a failure and your powertrain warranty is expired, you will now have reference material to show them this problem has been around prior to expiration. Then you have a chance at a "warranty repair" with an expired warranty.

Hard to say, usually I see 20-25PSI cold when it is at the "half-failure" point. So you are lowering than normal, but also higher than the expect failure points

Got it. Currently on live chat with GM, calling my dealer right now. I thought I was past worrying about the oil pump, but I guess the stress is only just beginning!

Thank you for your insight as always, Zach, it is much appreciated. 🍻

Car has been dropped off at the dealer. Here’s hoping for the best! I hope they offer some lenience and drop a new pump in there given the issue is well-known enough, and I have several pictures documenting the oil pressure < that magic 30 PSI threshold.

2022 vert with 1500 miles. ~40 at idle and in the low to mid 40s while driving.

Same with my 2023 Vert

UPDATE:

I hadn't heard anything back on the car since dropping it off on Monday; just called my Chevy dealer, the phone rep told me the car was currently getting an oil pump installed under warranty! I swear, less than 5 minutes later I get a text from my service adviser telling me the car is ready to go and that they swapped out the pump.

Unreal... I must have the greatest Chevy dealer of all time at my disposal; they've been incredibly pleasant to work with up to this point as well. Love those guys.

That has to be the fastest warranty work of this magnitude ever performed.

But just like a dealership to have done the work without even telling you they were going to do it, or asking for your permission. Lol

It seriously does have to be the fastest ever. I dropped my car off on Monday, and now it's sitting in my driveway in time for Cars and Coffee tomorrow morning. Unreal service.

I'm not even mad about them not asking tbh, I expressed my concerns and how I suspected it was the pump, and if I can get it done under warranty to just do it, so I'm totally good with it. My face lit up at work when I made the call and they were like "oh yeah it's literally being worked on rn." lmaooo

Peep the 30 PSI at operating temp now!

Jealous.. shout out to Salt lake..

seems the newer cars (mine included) are running around 37-38 hot at idle. I wonder if it's due to newer pump design (if so did they put an older pump in your car?) or the software? If software I wonder if Chevy can do an update to boost the pressure?

Congrats on the quick warranty work! It’s good to hear that there are still some good dealers out there.

Very happy for you. Did they say if the oil pump had a break or start of break? I think I will follow your lead if I see it below 29-31 where I see it warm. I appreciate how you kept the community informed. Thank you.
