GM bulletin 03-06-04-017T
What it saysThis service bulletin provides information on availability of Diesel Fuel additives. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 1, 2023, received Aug 28, 2023, about the fuel/propulsion system. It names 95 model years across Chevrolet, GMC and Cadillac (2016–2024). 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 (2 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 95 model years this bulletin names have filed 19,270 complaints with NHTSA since 2015. 1,033 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.
On the 2022 Chevrolet Equinox, the 35 owners who gave an odometer reading for Fuel/Propulsion System reported it at a median of 24,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
My vehicle lost power while driving on the highway. It was later determined that the fuel pump controller module required replacement. Losing power while driving 65 mph was not enjoyable or safe. The GMC Dealer Service department made the assessment, replaced the module, and the vehicle is now in my possession and functioning as normal.

Purchased new chevy Colorado 4X4 extended cab with 3.6-liter v6, transmission 8-speed model 8l45. Transmission developed shudder during light throttle acceleration between 30 and 70 MPH. Shudder is cyclic lasting 4 - 12 seconds, reaccurring 45 - 90 seconds. Shudder feels similiar to driving over mild rumble strips or rough pavement.

Bought the vehicle new in 2019 currently at a dealership to have the third in tank electric fuel pump installed. When it was in the shop for the second fuel pump installation the technician informed me that the pump can go out at any time causing a potential accident. Fortunately truck wouldn’t start and was diagnosed at dealership

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 03-06-04-017T 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 03-06-04-017T 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 03-06-04-017T cover?
The manufacturer filed it against 95 model years across 3 brands (Chevrolet, GMC and Cadillac): 2023 Cadillac Escalade, 2022 Cadillac Escalade, 2021 Cadillac Escalade, 2022 Chevrolet Colorado, 2021 Chevrolet Colorado, 2020 Chevrolet Colorado and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
