Transmission.

Sounds like something is scratching the glass inside the door ... awful. Mine has done it from day one as well. Figured it was just another crappy design. Can't imagine GM actually doing anything about it.

How do you know it isn't the motor?

Thanks for the info. It was the front diff vent hose that was disconnected. Not sure if that was intentional or accidental. Glad I saw it. I put it back on. Is there supposed to be a hose clamp to stop it from coming off?

So I took my truck to another dealership besides the one I bought it at to have them take a look at the leaking engine oil. Took 15 minutes for them to confirm leaking engine oil cooler hoses and they replaced them. They couldn't figure out why the other dealer needed to add dye to the engine oil and make me drive it around for 300 miles to make it leak more. They said it was totally obvious. So I just spent 2 hours cleaning up the undercarriage of the truck from the oil that was all over from the leaking and the repair and I came across this random hose. It is down by the front diff and terminates up near the battery where it is electrical taped onto a wiring harness. Does anyone know what it is? I don't recall seeing it before. If it was something important I can't believe that the service technician wouldn't have hooked it back up. Maybe I should just rip it off? Took off the right front wheel well liner to keep an eye on the engine oil cooler lines to see if they start leaking ... even though they were originally leaking at the engine block adapter. They also said something about a TSB for the adapter bolts being too long to get proper torque which made connection leak at gasket. I couldnt find that TSB and they didnt mention it in the notes. Check out pics. I also created a complaint with the NHTSA on the leaking oil cooler lines just in case anyone else is experiencing them. I had less than 1000 miles on the vehicle before I noticed the leak.

Ditto the fuse block bolts ... I had all kinds of weird stuff happening on mine including it dying on me while driving down the highway just to start up again on its own 20 seconds later ... happened multiple times. I torqued down those fuse block bolts and problem went away ... worth a shot ... would do it yourself vs dealer ... .02

Ugghh ... break out the stethoscope

Yes. Mainly clips but there are screws under the passenger side end cover after you take it off. Nothing complicated. Dealer can print off parts diagram for you for reference. What are you doing? I vinyl wrapped my wood grain trim for a different look.

Thanks for that info. Makes me feel a bit better when I have to drive around with the oil cooler lines leaking that there isn't a loss of pressure.

My 2023 Silverado LT 4WD has done this from day 1 with only 7 miles on the odometer. Primarily in reverse when turning wheels but more specifically I hear it when also compressing suspension at same time like backing out of my driveway which is on a slight incline. I thought maybe it was some control arm or other suspension bushings settling but it hasn't stopped. It's not as bad as a sway bar link noise or bad control arms but it is definitely there. Checked toque on everything suspension related (control arms, struts, sway bar) and they seemed fine. Maybe it is something with a CV axle ... seems early on for that to be an issue but hey, my new truck as been leaking engine oil since day 1 so a bad CV axle wouldn't surprise me.

Believe it or not the USB cable you use can impact this. I see you have changed USB cables already but have you used a high quality USB cable? There is a difference. I had to find the right cable before mine started behaving correctly and then over time due to flex of cable I believe pin wiring broke and it started to act up. Replaced cable and it was fine again. Here's and interesting article on USB cable construction comparison. https://www.lumafield.com/article/usb-c-cable-charger-head-to-head-comparison-apple-thunderbolt-amazon-basics

Sneaky Pete is correct. Oil leak is not repaired. Dealer where I bought truck hasn't called me back to schedule. I left them voicemail over 10 days ago letting them know it's still leaking after they put dye in it. I am hesitant to call them multiple times now since they told me I was making a big deal out of it. I am paying for a rental car out of pocket to minimize the amount I have to drive it but unfortunately I have to tow the landscaping equipment. Hopefully the dealership will call back soon. Oil level is fine on dipstick though so I thought maybe this oil pressure reading is normal. Never had digital gauge before. Pressure does increase at higher rpm.

What do normal oil pressure gauge readings look like for everyone? I have a 5.3. Is this low at idle? Thanks.

This happens to me frequently on 23 Silverado. I find that changing to Sirius XM and changing to a different preset cause infotainment to "unmute" ... definitely buggy.

On my steering wheels this has been the actual leather breaking down from use. I have bought leather steering wheel covers and hand stitched them on. They are a pain in the butt ... but look nice. I didn't use the same stitch pattern that they used from the factory but sewing this on by hand gave me a new appreciation for an OEM leather wrapped steering wheel.
