Measured by Transport Canada for its Canadian Vehicle Specifications database, which covers the North American versions of each model — here 6 configurations: Crew Cab L/Box 2WD, Crew Cab L/Box 4X4, Crew Cab S/Box 2WD, Crew Cab S/Box 4X4, Extended Cab L/Box 2WD, Extended 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%.

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
Source: New York State DMVIn New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2020 GMC Canyon failed the emissions check on 5.3% of first inspections — higher than the 2.2% for every 2020 model-year vehicle inspected; and the safety inspection on 0.53% (every 2020 vehicle: 1.6%).

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 2020 vehicle” is every 2020 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).
Canyon by model year
all years, side by side →Common questions about the 2020 Canyon
Source: EPA, NHTSA and manufacturer press kitsDoes the 2020 GMC Canyon have any recalls?
No NHTSA recall campaigns are on file for the 2020 GMC Canyon. New campaigns appear here within a week of NHTSA posting them, and a clean sheet on a recent model year often just means the vehicle is new.
How safe is the 2020 GMC Canyon?
NHTSA gave the 2020 GMC Canyon 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 A (100/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2020 GMC Canyon?
Across the 6 EPA-rated configurations of the 2020 GMC Canyon, the best EPA combined figure is 23 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2020 GMC Canyon?
Transport Canada measured it at 212.6–224.8 in long, 74.4 in wide (body, without mirrors), 70.5 in tall, on a 128.3–140.6 in wheelbase. Curb weight: 3,948–4,480 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 2020 GMC Canyon?
Owners have filed 14 complaints with NHTSA about the 2020 GMC Canyon, most often about power train, engine, electrical system. 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.
How clean is the 2020 GMC Canyon?
The EPA smog rating for the 2020 GMC Canyon runs 3 to 5 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 — California LEV-III ULEV125, California LEV-III ULEV70, Federal Tier 3 Bin 125, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2020 GMC Canyon?
The manufacturer has filed 862 service bulletins and related communications with NHTSA for the 2020 GMC Canyon, 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 2020 GMC Canyon do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2020 GMC Canyon failed the emissions check on 5.3% of first inspections — higher than the 2.2% for every 2020 model-year vehicle inspected; and the safety inspection on 0.53% (every 2020 vehicle: 1.6%). 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.

| Fuel economy & configurations | 6 configurations | EPA certification records | Every configuration the EPA certified for sale, with its own test figures. |
| Emission certificates | 6 configurations | EPA emission certificates | Smog rating, standard and the sales area that decides where the car can be sold new. |
| Recalls | none | NHTSA recall campaigns | No campaign has been filed. Because the register is complete, an empty row here means there is nothing to find — not that we are missing it. |
| Owner complaints | 14 | NHTSA complaint database | Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold. |
| Crash ratings | 4 tested | NHTSA NCAP | Only the configurations NHTSA chose to crash-test, which is never all of them. |

| 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. |

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.
