Chevrolet filed this with NHTSA as a service bulletin dated Mar 25, 2024, received Apr 15, 2024, about the service brakes. It names 6 model years (2019–2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 3,761 complaints with NHTSA since 2015. 417 of them name Service Brakes — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2019 Chevrolet Silverado, the 122 owners who gave an odometer reading for Service Brakes reported it at a median of 8,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Vehicle lost engine power on the road. Light display came on stating engine reduce power. It would not pull the trailer. Had to pull over and the display went away only to appear again later. We brought vehicle to chevrolet dealer . The part needed to hopefully fix is on backorder. There is also recall with no available remedy.

Common questions
Source: NHTSA, 49 CFR 579.5Is Chevrolet PIT6141 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the PIT6141 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every GM warranty extension on file lists the ones GM has filed.
Which vehicles does PIT6141 cover?
The manufacturer filed it against 6 model years: 2023 Chevrolet Silverado, 2022 Chevrolet Silverado, 2021 Chevrolet Silverado, 2020 Chevrolet Silverado, 2019 Chevrolet Silverado, 2019 Chevrolet 6500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
