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%.

Whether any of this applies to one specific Silverado
A campaign covers a build range, not a model year, so two identical-looking cars from 2017 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Chevrolet 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 2017 Chevrolet Silverado, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

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 Chevrolet itself: 172 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 7 killed, 219 injured, as claimed, not verified — about 41 per 100,000 built.

miles, typically
Half the 399 owner reports with an odometer reading on file fall between 18,000 and 70,000 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.

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.

At the New York inspection station

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 2017 vehicle” is every 2017 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).
Common questions about the 2017 Silverado
Source: EPA, NHTSA and manufacturer press kitsDoes the 2017 Chevrolet Silverado have any recalls?
NHTSA has posted 7 recall campaigns for the 2017 Chevrolet Silverado, 1 of them rated critical. The most serious on file is 16V256000, covering Suspension. There is an active do not drive advisory — act on it before driving. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2017 Chevrolet Silverado?
NHTSA gave the 2017 Chevrolet Silverado 5 stars overall in its New Car Assessment Program tests — 5-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it F (59/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2017 Chevrolet Silverado?
Across the 14 EPA-rated configurations of the 2017 Chevrolet Silverado, the best EPA combined figure is 20 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2017 Chevrolet Silverado?
Transport Canada measured it at 201.2–235.4 in long, 79.9 in wide (body, without mirrors), 73.6–74.0 in tall, on a 118.9–153.1 in wheelbase. Curb weight: 4,522–5,359 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 2017 Chevrolet Silverado?
Owners have filed 839 complaints with NHTSA about the 2017 Chevrolet Silverado, most often about power train, service brakes, engine. Of those, 49 involved a crash, 15 a fire, 21 reported injuries. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2017 Chevrolet Silverado?
The EPA smog rating for the 2017 Chevrolet Silverado runs 5 to 7 out of 10 across its configurations. That score covers tailpipe pollutants other than greenhouse gases, and it only compares vehicles within the same model year. It is certified for all fifty states, so it can be registered new anywhere in the U.S. Its configurations were certified to different standards — Bin 5, Federal Tier 3 Bin 70, LEV-III ULEV125, LEV-III ULEV70 — which the table above lists per configuration.
Are there service bulletins for the 2017 Chevrolet Silverado?
The manufacturer has filed 2183 service bulletins and related communications with NHTSA for the 2017 Chevrolet Silverado, 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.
How does the 2017 Chevrolet Silverado do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2017 Chevrolet Silverado failed the emissions check on 8.6% of first inspections — higher than the 3.7% for every 2017 model-year vehicle inspected; and the safety inspection on 2.0% (every 2017 vehicle: 2.1%). 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.

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.
