Engine — Loss of motive power due to engine failure closed

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 en

Whether any of this applies to one specific Sierra

A campaign covers a build range, not a model year, so two identical-looking cars from 2019 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 2019 GMC Sierra, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

When owners reported it

Reported at 13k

miles, typically

Half the 237 owner reports with an odometer reading on file fall between 5,000 and 71,000 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.

Vs same age is this model year’s median for the system divided by the median of every 2019-model-year complaint about the same system, all makes: under 1× means owners of this car reported it at lower mileage. Here, owners reported earlier than same-age vehicles: electrical system (0.52×), steering (0.64×); later: engine (2.0×). Which systems go early across the whole fleet: the component study.

Across 2018–2022 model years the GMC Sierra ranks 51 of 79 nameplates in the odometer-at-first-complaint study: owners reported problems at 1.37× the mileage of vehicles the same age (median 34,500 miles against a fleet 23,512).

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 DMV

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2019 GMC Sierra failed the emissions check on 5.7% of first inspections — higher than the 2.7% for every 2019 model-year vehicle inspected; and the safety inspection on 1.3% (every 2019 vehicle: 1.7%).

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 2019 vehicle” is every 2019 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 2019 Sierra

Source: EPA, NHTSA and manufacturer press kits

Does the 2019 GMC Sierra have any recalls?

NHTSA has posted 10 recall campaigns for the 2019 GMC Sierra, 2 of them rated critical. The most serious on file is 19V888000, covering Electrical System. 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 2019 GMC Sierra?

NHTSA gave the 2019 GMC Sierra 5 stars overall in its New Car Assessment Program tests — 4-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it F (45/100) on its recall record, which is a different question from crash protection.

What is the fuel economy of the 2019 GMC Sierra?

Across the 22 EPA-rated configurations of the 2019 GMC Sierra, the best EPA combined figure is 21 mpg. Figures are the EPA's own, per configuration, and every one is listed above.

What are the dimensions of the 2019 GMC Sierra?

Transport Canada measured it at 225.6–241.3 in long, 79.9–81.1 in wide (body, without mirrors), 74.0–75.6 in tall, on a 143.7–156.7 in wheelbase. Curb weight: 4,619–5,115 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 2019 GMC Sierra?

Owners have filed 684 complaints with NHTSA about the 2019 GMC Sierra, most often about engine, power train, service brakes. Of those, 13 involved a crash, 3 a fire, 13 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 2019 GMC Sierra?

The EPA smog rating for the 2019 GMC Sierra runs 3 to 6 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 ULEV50, California LEV-III ULEV70, Federal Tier 3 Bin 125, Federal Tier 3 Bin 50, Federal Tier 3 Bin 70 — which the table above lists per configuration.

Are there service bulletins for the 2019 GMC Sierra?

The manufacturer has filed 2400 service bulletins and related communications with NHTSA for the 2019 GMC Sierra, most often covering equipment, engine, electrical system. The most recent is dated 2026-10-15. 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 2019 GMC Sierra do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2019 GMC Sierra failed the emissions check on 5.7% of first inspections — higher than the 2.7% for every 2019 model-year vehicle inspected; and the safety inspection on 1.3% (every 2019 vehicle: 1.7%). 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.

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.
