New-vehicle warranty
Source: manufacturer press kits, make-levelAs stated in GMC's press kits for the 2026–2027 model years (6 kits); this model year's own kit states no warranty terms, so the make's are shown. Confirm the term for this car with the dealer.
The cheapest ownership win
Insurers price the 2027 Sierra 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.

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.

Sierra by model year
all years, side by side →Common questions about the 2027 Sierra
Source: EPA, NHTSA and manufacturer press kitsHow much does the 2027 GMC Sierra cost?
Manufacturer pricing runs from $51,295 for the Pro 2WD to $87,895 for the Denali Ultimate 2WD, across 10 trims. Those are MSRPs from the manufacturer's own press material; they exclude destination, options, taxes and whatever the dealer adds. Every trim and price is listed above.
Does the 2027 GMC Sierra have any recalls?
No NHTSA recall campaigns are on file for the 2027 GMC Sierra. 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 2027 GMC Sierra?
NHTSA has not published a crash-test rating for the 2027 GMC Sierra yet. On the recall record WhichTrim grades it A (100/100), which measures open and severe recalls rather than crash protection.
What is the fuel economy of the 2027 GMC Sierra?
Across the 10 EPA-rated configurations of the 2027 GMC Sierra, the best EPA combined figure is 24 mpg (MPGe on the electrified versions) and the longest EPA range is 396 miles on a charge. Figures are the EPA's own, per configuration, and every one is listed above.
Are there service bulletins for the 2027 GMC Sierra?
The manufacturer has filed 17 service bulletins and related communications with NHTSA for the 2027 GMC Sierra, most often covering unknown or other. The most recent is dated 2026-11-07. 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.
Which 2027 GMC Sierra trim is the best value?
$36,600 separates the cheapest of the 10 trims from the most expensive, so the answer depends on which of the differences you would actually use. Every trim has its own page here with the manufacturer's full specification and equipment list, plus a short summary of exactly what it adds over the base trim — worth reading before a dealer frames the walk-up for you. The trim-by-trim ladder shows what every step up costs and what it makes standard.
Is the 2027 GMC Sierra better than the 2027 Ram 1500?
The GMC Sierra wins clearly, 88.9 to 74.4, on fuel & range, performance. The Ram 1500 is ahead on safety. We publish a full side-by-side of the 2027 GMC Sierra against the 2027 Ram 1500 — specifications by family, equipment feature by feature, safety record and ownership costs. You can re-weight what matters to you and the verdict recalculates.
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 | 10 configurations | EPA certification records | Every configuration the EPA certified for sale, with its own test figures. |
| Emission certificates | none | EPA emission certificates | The EPA published no certificate we could match to a configuration on this page. |
| 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 | none | NHTSA complaint database | No owner has filed one. On a car that sold in small numbers this says very little either way. |
| Crash ratings | none | NHTSA NCAP | NHTSA has not tested this model year. Cars are selected for testing, so untested is not unsafe. |
| Service bulletins | 17 | 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 | none | NHTSA vPIC, decoded from VIN patterns | We had no VIN pattern to decode for this model year, or the manufacturer filed nothing usable. |
| Trims, pricing & equipment | 10 trims | Manufacturer press kit | Transcribed from the manufacturer's own press material, every value carrying the document it came from. |

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. Trim-level specifications and pricing are transcribed from the manufacturer's official press kit; every value carries its source in the data file.
