What it saysThis Preliminary information communicates to dealers engine wiring harness inspections and engine oil pump diagnostic testing related to MIL on with P0521, P06DD or P06DE. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 13, 2024, about the electrical system. It names 4 model years across Chevrolet and Buick (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.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches GM’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 4 model years this bulletin names have filed 294 complaints with NHTSA since 2015. 127 of them name 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 2024 Chevrolet Trax, the 15 owners who gave an odometer reading for Electrical System reported it at a median of 16,400 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The instrument panel intermittently blacks out while driving. I have taken it back to the dealer twice and they are unable to reproduce the issue. The first time, they said it was a software issue and ran an update, but that did not fix the problem. I found online that this is a known issue so I contacted Buick Customer Care.
2024 Buick Envista · Electrical System · filed with NHTSA Apr 11, 2025
The contact owns a 2024 Chevrolet Trax. The contact stated that while the vehicle was parked, the vehicle was remotely started erroneously. The vehicle was taken to the local dealer who determined that the infotainment system had been hacked. The infotainment center software was reloaded but the failure continued to occur.
2024 Chevrolet Trax · Electrical System · filed with NHTSA Mar 25, 2024
The contact owns a 2024 Buick Encore. The contact stated that while attempting to start the vehicle, the instrument panel displayed a blank screen. In addition, the contact stated that the failure occurred every 31 seconds. The vehicle was taken to the dealer where it was diagnosed with a failed VCU module.
2024 Buick Encore · Electrical System · filed with NHTSA May 21, 2026
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 PIP5932D 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 PIP5932D 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.
Which vehicles does PIP5932D cover?
The manufacturer filed it against 4 model years across 2 brands (Chevrolet and Buick): 2024 Buick Encore, 2024 Buick Envista, 2024 Chevrolet Trailblazer, 2024 Chevrolet Trax. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
