I have had the same issue since the 400 mile mark. They have replaced the differential twice with no resolution. I also have transmission issues that my truck has been in the shop for 30 days this time alone. It's been in the shop for over 55 days total and I bought it on April 9th 2109. GM refused my buyback and said they'd just keep on fixing it under warranty. This is my 4th Silverado and I will never own another GM vehicle. The differential still makes the chirping noise at higher speeds now but is still loud enough to hear over the engine and radio. When you drive the truck for about an hour the transmission will slam in to 1st gear as you slow down to come to a stop. Feels like someone rear ends my truck. After being told it was normal, GM admits there is a major problem and now shipping my dealership additional parts to throw another band aid at it and hope I give up I guess. It slammed so hard once that the sales manager wouldn't drive my truck because he thought it was unsafe to drive. That was 2 months ago. I was on the highway running 72 going around a curve and it slammed into gear and the truck shook. I thought the car beside me had hit me almost causing a wreck. My son was asleep in the back and woke up thinking we wrecked. They did offer me additional warranty but can't fix either issues I have under the initial warranty. I have several videos of the issues that I'll post in a few.

Hope I have the same outcome. Hoping for the best. Congrats!! Just wish GM would split my payment this month since it's been being worked on more than not. Lol

Just got a call from my service department and they said my truck was the first one that had a new differential put in that didn’t fix the issue. They are replacing the differential a second time and we will go from there. I know our service department is trying to fix it I’m just afraid the new one will do the same.

Meant to quote instead of new post. It's identical to the one in your video. That's what I was told was normal. They have opened a case with GM and hope that they make some progress. All my Ford owner friends are ruthlessly making fun of my new truck.

I was told today that the noise is normal and that if there was anything out there it would have a bulletin on it if a field manager had found something wrong. They kept my truck again and they have no idea of what to do to fix it or if they even will be able to in the future.

Well the dealer replaced my front differential and the noise is still as loud or louder. Heading back to the service department again on Monday morning. Hoping with this new information from this forum they will at least check into it. Thanks for all that are posting and helping find where the defect is.

I took my 2019 in on April 29th and was told today that the differential that they ordered for my new truck would be several more days til it's in. It will have spent more time in the shop than not after this is replaced. Good luck to everyone having this issue. Very disappointed to say the least.

I am having the same issue and have since 500 miles. They'replaced the front differential but is still making the grinding noise. Kinda sounds like a metal on metal noise that seems to be louder the more you drive it. Mine stops making the noise in 4WD as well. Update if you get any resolution.
