GM bulletin PIP5962
What it saysThis Preliminary information communicates how to isolate a tick noise from the rear axle housing. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Feb 21, 2024, received Mar 18, 2024, about the power train. It names 12 model years across Chevrolet and GMC (2019–2024). 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 7,382 complaints with NHTSA since 2015. 1,875 of them name Power Train — 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 106 owners who gave an odometer reading for Power Train reported it at a median of 15,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
I was driving and noticed a very strong smell of an electrical fire. The truck popped up a High Voltage Battery warning and several warning lights came on. We stopped, restarted the truck and the lights came on again, the smell returned as soon as we started driving. We drove the truck to Cable Dahmer GMC in Kansas City, MO.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIP5962 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 PIP5962 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 PIP5962 cover?
The manufacturer filed it against 12 model years across 2 brands (Chevrolet and GMC): 2024 Chevrolet Silverado, 2023 Chevrolet Silverado, 2022 Chevrolet Silverado, 2021 Chevrolet Silverado, 2020 Chevrolet Silverado, 2019 Chevrolet Silverado and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
