The 2016 GMC Sierra 3500HD 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, 3 rated critical, which gives it a Safety Signal grade of F. Owners have filed 19 complaints, most often about the service brakes.

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, SLT). 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 16 configurations: Crew Cab L/Box Drw 2WD, Crew Cab L/Box Drw 4X4, Crew Cab L/Box Drw 4X4 Denali, Crew Cab L/Box Srw 2WD, Crew Cab L/Box Srw 4X4, Crew Cab M/Box 2WD …. 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%.

Problem General Motors, LLC (GM) is recalling certain 2016-2018 GMC Sierra 3500 and Chevrolet Silverado 3500 trucks equipped with gasoline engines and dual fuel tanks. The fuel-level sensor in the front tank may stick in a low-level position, allowing the rear tank to overfill the front tank. Risk If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire. Fix GM has notified owners, and dealers will replace the rear-tank fuel-pump module, inspect the front tank and, if necessary, replace the front tank, free of charge. The recall began July 30, 2019. GM's number for this recall is N182204190.

The brake pedal pivot nut may loosen, causing the brake pedal to be loose or inoperative. Risk If the brake pedal becomes loose or inoperative, the driver may be unable to stop the vehicle by using the brake pedal. Additionally, a loose pedal may also interfere with the accelerator pedal. Either condition may increase the risk of a crash. Fix GM will notify owners, and dealers will add adhesive to the nut and reinstall the nut with increased tightness, free of charge.

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 3500HD

A campaign covers a build range, not a model year, so two identical-looking cars from 2016 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 2016 GMC Sierra 3500HD, 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.

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 2016 Sierra 3500HD

Source: EPA, NHTSA and manufacturer press kits

Does the 2016 GMC Sierra 3500HD have any recalls?

NHTSA has posted 7 recall campaigns for the 2016 GMC Sierra 3500HD, 3 of them rated critical. The most serious on file is 19V088000, covering Fuel System, Gasoline. 1 of them was 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 2016 GMC Sierra 3500HD?

NHTSA has not published a crash-test rating for the 2016 GMC Sierra 3500HD yet. On the recall record WhichTrim grades it F (46/100), which measures open and severe recalls rather than crash protection.

What are the dimensions of the 2016 GMC Sierra 3500HD?

Transport Canada measured it at 220.1–254.3 in long, 79.9–96.1 in wide (body, without mirrors), 77.2–78.3 in tall, on a 133.5–167.7 in wheelbase. Curb weight: 5,774–8,014 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 2016 GMC Sierra 3500HD?

Owners have filed 19 complaints with NHTSA about the 2016 GMC Sierra 3500HD, most often about service brakes, steering, engine. 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 2016 GMC Sierra 3500HD?

The manufacturer has filed 661 service bulletins and related communications with NHTSA for the 2016 GMC Sierra 3500HD, 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.
