Chevrolet bulletin PIP5781D
Chevrolet filed this with NHTSA as a service bulletin dated Mar 31, 2026, received Apr 7, 2026, about the unknown or other. It names 7 model years (2020–2026). 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. Quote it at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Chevrolet PIP5781D 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 PIP5781D 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 PIP5781D cover?
The manufacturer filed it against 7 model years: 2026 Chevrolet Corvette, 2025 Chevrolet Corvette, 2024 Chevrolet Corvette, 2023 Chevrolet Corvette, 2022 Chevrolet Corvette, 2021 Chevrolet Corvette and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
