GM bulletin PIP5988
What it saysThis preliminary information communicates to technicians not to replace the injection pump for DTCs P0089 and P2293, but to replace the fuel rail instead. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Sep 6, 2024, about the engine. It names 2 model years across Chevrolet and GMC (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.

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 2 model years this bulletin names have filed 735 complaints with NHTSA since 2015. 392 of them name Engine — 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 2024 GMC Sierra, the 27 owners who gave an odometer reading for Engine reported it at a median of 25,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Exactly what was described in the N192220080 Recall on New Model 2019 Chevy Silverados in cold climates (Like Utah winters) so at 45,280 miles the oil line popped out just like the recall described There were no oil leaks or signs of oil loss in the driveway where the truck is parked.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIP5988 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 PIP5988 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 PIP5988 cover?
The manufacturer filed it against 2 model years across 2 brands (Chevrolet and GMC): 2024 Chevrolet Silverado, 2024 GMC Sierra. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
