My IntelliBeam function stops working sometimes, I can still use the lights as normal but the IntelliBeam function stops every so often and starts working after about 2 to 10 mins. Lane departure warning stops every so often and will start working after 1 to 10 mins, I have noticed that when it stops working at night time then the IntelliBeam function stops working also. When I press the on/off button for lane departure then it will say that lane departure is unavailable right now. I have been getting a p20ee code showing something is wrong with SCR nox sensor 2. Scan tool reveals that the sensor works normal and then stops. Once I clear the code then it works good for a few days.

Contacted General Motors to have the Recall software patch installed, appoint was set, vehicle was dropped off and now they are telling me there is nothing they can do, that the recall is not available. The software update is available, and is being installed on other vehicles. This is a life safety issue as the rear wheels can lock up at any time which could cause a vehicle accident involving the vehicle under recall as well any vehicles on the road around this vehicle when it happens. General Motors should be taking care of this asap instead of waiting. I do not feel safe driving the vehicle until they feel like they installing it.

Is 45 complaints a lot? They were filed between 2019 and 2025, roughly 8 a year, which is about the same as the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2020 has 45 complaints on file, more than the 2019 (13) and more than the 2021 (20). That is the most of the 13 model years of the GMC Sierra 3500 we cover. Older model years have had longer to collect complaints.
