2024 GMC Sierra 2500HD
The 2024 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 4 recall campaigns for this model year, 1 rated critical, which gives it a Safety Signal grade of C. Owners have filed 107 complaints, most often about the electrical system.

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: AT4, AT4X, Denali, Denali Ultimate). Figures for the trim you are looking at may differ.

Measured by Transport Canada for its Canadian Vehicle Specifications database, which covers the North American versions of each model — here 10 configurations: Crew Cab L/Box 2WD, Crew Cab L/Box 4X4, Crew Cab M/Box 2WD, Crew Cab M/Box 4X4, Double Cab L/Box 2WD, Double Cab L/Box 4X4 …. 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%.

The cheapest ownership win
Insurers price the 2024 Sierra 2500HD very differently, and the gap between the best and worst quote on the same car and driver is usually larger than any option you are weighing on this page.

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 2024 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 2024 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 contact owned a 2024 GMC Sierra 2500 HD. The contact stated that after parking the vehicle at night and plugging in the engine block heater to a standard 110-Volt outlet with an extension cord; 15-minutes later neighbors were screaming to the contact to exit the residence because the vehicle had caught on fire, and the residence was…
First date was 04/23/2024 my truck went into limp mode with an alert reading engine and transmission control module problem. Brought it in and they reset the sensors. Shortly after the alert warning goes off again and I turn the engine off and start it back up. It cleared the alert, I brought it back in on 06/15/2024.
I drove from California to ohio after I bought the truck, I noticed that when stopping to get gas my tailgate was open without me touching it. I drove with cameras showing the truck bed to see what happened and I watched it do it again while driving the vehicle, it just opened on its own while driving.
I purchased a 2024 GMC 2500 HD truck to pull a 2021 8,000 lb gvw camping trailer that is equipped with electric trailer brakes. My trailer has functioned perfectly related to the trailer brakes with my previous vehicle (2011 Toyota Tundra).
The contact owns a 2024 GMC Sierra 2500. The contact stated that while driving at an undisclosed speed, the vehicle briefly hesitated before returning to normal functionality. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transfer case seals.
The contact owns a 2024 GMC Sierra 2500. The contact stated while driving approximately 45–50 MPH in the rain, the tail gate opened unintendedly. There were no warning lights illuminated. The contact stated that cargo in the bed of the truck fell out onto the roadway.
Complaint counts are raw owner reports to NHTSA, not verified defects, and scale with how many were sold. Use them to spot patterns, not to rank.
Reported by GMC itself: 22 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 25 injured, as claimed, not verified — about 18 per 100,000 built.

When owners reported it
miles, typically
Half the 29 owner reports with an odometer reading on file fall between 3,000 and 41,000 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.
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.

At the New York inspection station
Source: New York State DMVIn New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2024 GMC Sierra 2500HD failed the emissions check on 0.54% of first inspections — lower than the 1.5% for every 2024 model-year vehicle inspected; and the safety inspection on 0.58% (every 2024 vehicle: 0.74%).

New York’s emissions test on these model years is an on-board diagnostics check: it fails a car whose check-engine light is on or whose self-tests have not finished. First inspections only, so a car that failed and came back is counted once; private and special plates, not taxis, livery or commercial plates. A rate appears only where at least 200 inspections stand behind it. “Every 2024 vehicle” is every 2024 model-year car, SUV and pickup inspected in the same window, all makes. This is the state’s record of test results, not a reliability score by itself. Source: New York State Department of Motor Vehicles, Vehicle Inspections (data.ny.gov, Open NY terms).
Sierra 2500HD by model year
all years, side by side →Common questions about the 2024 Sierra 2500HD
Source: EPA, NHTSA and manufacturer press kitsDoes the 2024 GMC Sierra 2500HD have any recalls?
NHTSA has posted 4 recall campaigns for the 2024 GMC Sierra 2500HD, 1 of them rated critical. The most serious on file is 23V549000, covering Steering. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2024 GMC Sierra 2500HD?
NHTSA has not published a crash-test rating for the 2024 GMC Sierra 2500HD yet. On the recall record WhichTrim grades it C (71/100), which measures open and severe recalls rather than crash protection.
What are the dimensions of the 2024 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 2024 GMC Sierra 2500HD?
Owners have filed 107 complaints with NHTSA about the 2024 GMC Sierra 2500HD, most often about electrical system, power train, service brakes.

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 2024 GMC Sierra 2500HD do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2024 GMC Sierra 2500HD failed the emissions check on 0.54% of first inspections — lower than the 1.5% for every 2024 model-year vehicle inspected; and the safety inspection on 0.58% (every 2024 vehicle: 0.74%). 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 | 4 | NHTSA recall campaigns | A complete federal register: every campaign covering this model year, with severity and advisory flags. |
| Owner complaints | 107 | NHTSA complaint database | Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold. |
| Crash ratings | 2 tested | NHTSA NCAP | Only the configurations NHTSA chose to crash-test, which is never all of them. |
| Service bulletins | 860 | 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. |

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.
