GM filed this with NHTSA as a service bulletin dated Oct 12, 2023, received Nov 6, 2023, about the electrical system. It names 2 model years across Chevrolet and GMC (2019). 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 2 model years this bulletin names have filed 1,784 complaints with NHTSA since 2015. 1,066 of them name Engine, Electrical System — 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 143 owners who gave an odometer reading for Engine reported it at a median of 71,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2019 Chevrolet Silverado 5500. The contact stated while driving at various speeds, the vehicle loss motive power and stalled. The failure recurred on several occasions with the check engine warning light illuminated. The contact was unable to restart the vehicle.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM 19-NA-151 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 19-NA-151 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 19-NA-151 cover?
The manufacturer filed it against 2 model years across 2 brands (Chevrolet and GMC): 2019 Chevrolet Silverado, 2019 GMC Sierra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
