The 2019 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 7 recall campaigns for this model year, 5 rated critical, which gives it a Safety Signal grade of F. Owners have filed 32 complaints, most often about the electrical system. NHTSA crash-tested it at 4 stars overall.

Filed by the manufacturer with NHTSA under the federal vehicle-identification rule and decoded from the VIN pattern — not a manufacturer press kit, so it describes the configurations we could identify rather than every trim (seen: Denali, Fleet/Base, SLE, SLT). Figures for the trim you are looking at may differ.

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%.

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 2019 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 2019 GMC Sierra 2500HD, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

In owners' own words

Filed with NHTSA by the people who own these cars, one per problem area. Quoted as written, with anything identifying removed.

The manufacturer placed two 12v batteries to start the truck with one being located on the passenger side just in front of the cowl of the cab. The factory OEM batteries are known to overheat when charging which is exactly what mine did and as the battery boils over with sulfuric acid, the acid is vaporized and ingested into the cabin.

When owners reported it

Reported at 32k

miles, typically

Half the 12 owner reports with an odometer reading on file fall between 15,000 and 49,000 miles. That is when problems get reported, which is not the same as when they start — and not a failure rate, because nobody knows how many of these cars never had a problem at all.

Too few readings for a curve — the 12 on file: 1 under 10k, 3 10k–20k, 2 20k–30k, 2 30k–40k, 1 40k–50k, 1 60k–70k, 1 80k–90k, 1 100k–150k.

Odometer readings as filed by owners with NHTSA. Readings under 100 or over 400,000 miles are dropped as data entry rather than history, and a component needs at least 12 readings before a median is shown for it.

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 2019 Sierra 2500HD

Source: EPA, NHTSA and manufacturer press kits

Does the 2019 GMC Sierra 2500HD have any recalls?

NHTSA has posted 7 recall campaigns for the 2019 GMC Sierra 2500HD, 5 of them rated critical. The most serious on file is 26V325000, covering Air Bags. 2 of them were filed with no repair available at the time — NHTSA's file records what the manufacturer had in hand on the filing date, not what exists today. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2019 GMC Sierra 2500HD?

NHTSA gave the 2019 GMC Sierra 2500HD 4 stars overall in its New Car Assessment Program tests — 4-star frontal crash, 5-star side crash, 3-star rollover. WhichTrim also grades it F (38/100) on its recall record, which is a different question from crash protection.

What are the dimensions of the 2019 GMC Sierra 2500HD?

Transport Canada measured it at 220.1–254.3 in long, 79.9 in wide (body, without mirrors), 78.0–78.3 in tall, on a 133.5–167.7 in wheelbase. Curb weight: 5,631–6,594 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 2019 GMC Sierra 2500HD?

Owners have filed 32 complaints with NHTSA about the 2019 GMC Sierra 2500HD, most often about electrical system, engine, fuel/propulsion system. Of those, 3 a fire, 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 2019 GMC Sierra 2500HD?

The manufacturer has filed 945 service bulletins and related communications with NHTSA for the 2019 GMC Sierra 2500HD, most often covering equipment, engine, electrical system. The most recent is dated 2026-09-26. 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.

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.

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.
