The 2023 GMC Sierra 2500HD is a pickup truck; vehicles over 8,500 lb GVWR are not certified for fuel economy by the EPA, so this page is built from NHTSA's recall, complaint and investigation records. NHTSA lists 1 recall campaign for this model year, which gives it a Safety Signal grade of A. Owners have filed 33 complaints, most often about the power train.

Where a range is shown, those versions differ. Width is the body without mirrors, which is why it can read narrower than a brochure figure. Before we used it we checked it against the US manufacturer press kits we hold (27 Sep 2026): wheelbase agreed within 1% on every vehicle we could compare, length on 98%, and the curb weight fell inside the manufacturer's range on 96%.

N232426400

570,434 vehicles 74% reported repaired

Problem General Motors, LLC (GM) is recalling certain 2020-2024 Chevrolet Silverado 2500, 3500, GMC Sierra 2500 and 3500 vehicles equipped with power-unlatching tailgates. The tailgate's electronic gate-release switch may short circuit due to water intrusion, which can result in the tailgate inadvertently unlatching while the vehicle is in park. Risk An unlatched tailgate may open while driving and result in a loss of unsecured cargo, creating a road hazard and increasing the risk of a crash. Fix Owners are advised to check that the tailgate is closed and latched before driving. Dealers will replace the exterior touchpad switch assemblies, free of charge. Owner notification letters were mailed May 17, 2024. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232426400.

NHTSA campaign 24V060000 reported Feb 1, 2024 General Motors, LLC the full filing, and every vehicle covered →

These are vehicle campaigns — the ones the automaker filed against this model. NHTSA also records equipment recalls, filed by a parts maker against a component (a tyre, a child seat, an aftermarket part), and those are not listed here or counted above. nhtsa.gov/recalls shows both for a VIN.

Whether any of this applies to one specific Sierra 2500HD

A campaign covers a build range, not a model year, so two identical-looking cars from 2023 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. GMC publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.

Hear about a recall before the letter does

The manufacturer’s letter is the last step of a recall: it has up to 60 days after filing to mail owners, at the address on the registration. We email you the day NHTSA posts a recall on the 2023 GMC Sierra 2500HD, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

A service bulletin is the manufacturer telling its dealers how to diagnose or repair a known condition. It is not a recall, not a finding that the vehicle is defective, and the work is not automatically free — though a bulletin is often what a dealer works from when you describe a symptom, so quoting the document number can save a diagnosis. The count is every communication filed; the list shows the most recent, one entry per campaign, because a single campaign is usually filed as several documents on the same day. The summaries are NHTSA's; the full documents come from the manufacturer.

Generic codes (the second character is 0 or 2) mean the same thing on every vehicle sold in the United States. Manufacturer-specific codes (1 or 3) mean whatever the automaker assigned, and no honest source can define them for you — which is why the ones here carry the evidence instead of a definition. A code is a link when enough separate federal documents name it across the catalogue to be worth a page of its own; the rest are listed here, where the vehicle is the context that makes them mean something.

Common questions about the 2023 Sierra 2500HD

Source: EPA, NHTSA and manufacturer press kits

Does the 2023 GMC Sierra 2500HD have any recalls?

NHTSA has posted 1 recall campaign for the 2023 GMC Sierra 2500HD. The most serious on file is 24V060000, covering Latches/Locks/Linkages. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2023 GMC Sierra 2500HD?

NHTSA has not published a crash-test rating for the 2023 GMC Sierra 2500HD yet. On the recall record WhichTrim grades it A (92/100), which measures open and severe recalls rather than crash protection.

What are the dimensions of the 2023 GMC Sierra 2500HD?

Transport Canada measured it at 235.4–266.1 in long, 81.9 in wide (body, without mirrors), 79.9 in tall, on a 141.7–172.0 in wheelbase. Curb weight: 5,924–6,731 lb depending on configuration. Those are its measurements of the North American versions; every figure is in the table above.

What do owners complain about on the 2023 GMC Sierra 2500HD?

Owners have filed 33 complaints with NHTSA about the 2023 GMC Sierra 2500HD, most often about power train, electrical system, service brakes. Of those, 1 involved a crash, 1 reported injuries. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.

Are there service bulletins for the 2023 GMC Sierra 2500HD?

The manufacturer has filed 764 service bulletins and related communications with NHTSA for the 2023 GMC Sierra 2500HD, most often covering engine, unknown or other, electrical system. The most recent is dated 2026-10-07. A bulletin is not a recall: it is the repair procedure a manufacturer sends its dealers for a condition it knows about, and the work is not automatically paid for. It is still worth knowing — if the symptom matches, quoting the bulletin number at the service desk can save a diagnosis. The document numbers and summaries are listed above.

How does the 2023 GMC Sierra 2500HD do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2023 GMC Sierra 2500HD failed the safety inspection on 0.57% of first inspections — lower than the 1.1% for every 2023 model-year vehicle inspected. The figures are New York State DMV’s own inspection records, first inspections only, and the table above sets each one against every vehicle of the same model year.

What we hold, and what an empty row means

Paid vehicle-history reports will not tell you the difference between “nothing happened to this car” and “we never received that record” — both of the big two say as much in their own help pages. Most of what is on this page comes from complete federal registers, so we can tell you which is which, row by row.

Data	Held	Source	What it covers — or what empty means
Fuel economy & configurations	none	EPA certification records	The EPA does not certify vehicles rated over 8,500 lb GVWR, so heavy-duty nameplates have no entry at all.
Emission certificates	none	EPA emission certificates	The EPA published no certificate we could match to a configuration on this page.
Recalls	1	NHTSA recall campaigns	A complete federal register: every campaign covering this model year, with severity and advisory flags.
Owner complaints	33	NHTSA complaint database	Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold.
Crash ratings	none	NHTSA NCAP	NHTSA has not tested this model year. Cars are selected for testing, so untested is not unsafe.
Service bulletins	764	NHTSA manufacturer communications	Everything the manufacturer told its dealers about a defect or malfunction, short of a recall.
Investigations	none	NHTSA Office of Defects Investigation	No defect investigation has been opened.
Driver-assist crash reports	none	NHTSA Standing General Order 2021-01	No report has been filed. Only entities named in the order report, and only crashes they hear of — so this is also what an unequipped car, or a manufacturer without telematics, looks like.
Specifications filed with NHTSA	7 fields	NHTSA vPIC, decoded from VIN patterns	What the manufacturer filed under the federal VIN rule — a configuration, not the full trim ladder.
Measured dimensions	7 fields	Transport Canada, Canadian Vehicle Specifications	Length, width, height, wheelbase, track and curb weight, measured on the North American versions.
Trims, pricing & equipment	none	Manufacturer press kit	We have not transcribed a press kit for this model year yet. This is our gap, not the manufacturer's — the one row here where an empty cell means we are behind.

Sources & method

Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). The most serious recall counts in full and each further one counts 85% of the one before, because a vehicle sold in millions is recalled more often than a rare one without being more dangerous — and because a flat subtraction bottomed the scale out, scoring a vehicle with 22 recalls within a point of one with six. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Read it as what it counts: recall campaigns on the federal record, weighted by severity. The damping reduces the sales bias by roughly 40% but does not remove it: like our complaint counts, this is not normalized by how many were sold, so a best-seller still scores somewhat worse than an obscure model with the same real risk. NHTSA crash ratings, do-not-drive and park-outside advisories, and the crash, fire, injury and death counts in owner complaints are reported separately on every page and never blended into the letter — a vehicle can hold five stars and a poor letter at once, and where that happens we say so rather than leave you to notice. Because the scale subtracts from a clean sheet, a model year too new to have been recalled, complained about or bulletined scores full marks on an empty record; we label those grades provisional rather than present them as earned.

EPA figures come from fueleconomy.gov vehicle records. Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed nightly.
