What it saysCertain vehicles may have a condition in which the software that maintains the RESS battery pack may inadvertently cause a drain on the high voltage and low voltage batteries. NHTSA’s full summary ↓

Chevrolet filed this with NHTSA as a service campaign dated Oct 5, 2026, received Jul 21, 2026, about the fuel/propulsion system — 2 documents under this number. It names 1 model year (2027). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

What the document itself lists

The manufacturer titles it “UPDATE: N262559000-01 - Service Update”.

Labour operations and the time the manufacturer allows

Read by machine from the document NHTSA serves (5 pages), read Sep 30, 2026. A part number is shown only where it matches Chevrolet’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.

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 database

Owners of the 1 model year this bulletin names have filed 6 complaints with NHTSA since 2015. 1 of them name Fuel/Propulsion 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.

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.
