      This is long – Sorry!

      Truck was new on 11-31-2020. During October 2021, it started producing a rubbing sort of noise on one of the front wheels – could not tell which one, but sounded like the right front. The noise is rotational, meaning – it is only when the wheel rotates at the beginning of the wheel travel for about 1/4 rotation, and then the balance of the wheel travel, nothing, until it makes a full rotation — then it starts again and repeats itself. On October it only presented when the temperature was around 40 degrees (Wisconsin). The rubbing noise only last for maybe 50-75 feet of travel and then quit. It was as though once it got warm, it quit.

      I took the truck to a GMC dealer, and left it overnight so they could drive it first thing in the morning while it was cold. The tech heard the noise, inspected the right front brake, and determined that nothing was wrong.

      I questioned if the noise was a wheel bearing. Dealer says not because it’s not noisy during the entire wheel rotation, and also, when off-loaded from turning left to right. I asked about a CV joint, and they could not find anything in the GM database for a technical service bulletin.

      Fast Forward to March 2022 (30,210 miles). The noise has never quit. Now it is louder than it was last fall and the noise can be heard 70-degree temps here in Alabama. The noise seems to be more prevalent when turning the steering wheel to the left. You can definitely feel a vibration through the steering wheel while the rotational noise is present. Same deal, once it gets warm, it goes away.

      GM warranty is soon to run out at 36K. I’m told that GM will honor the warranty work order from October 2021, if it became an issue down the road post warranty.

      My Question: Has anyone had a similar experience and if so, what was the determination?

      Thanks in advance for your time here.

      Other than the turning symptom you mention, this aligns with the symptoms of a minor warp in the rotor. Once heated from the friction to the brake bad the metal warps back flat. Over time the heat fatigue will make the symptoms worse, last longer, occur at different temperatures, etc.

      My 2020 3500 has been doing pretty much the same thing as yours. It’s currently at the dealership getting the DEF recall issue done. I told them about the noise from the front wheel area now and then. They couldn’t recreate the noise and they said they checked everything out and it looked good.
      Mine started making the noise on and off withing the first week of owning it. It just doesn’t do it all the time.
