Engine — Loss of motive power due to engine failure post recall remedy open

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or a

Whether any of this applies to one specific Suburban

A campaign covers a build range, not a model year, so two identical-looking cars from 2023 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.

In October 2024, the vehicle just shut off while we were driving down the road. Had to pull off to the side and got it going after about 5 minutes. Couldn't get the vehicle to replicate the problem so nothing chevy could do. No check engine light. No codes were given. On January 4th the vehicle started making a horrible noise.

Reported at 44k

miles, typically

Half the 18 owner reports with an odometer reading on file fall between 25,000 and 100,000 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.

Too few readings for a curve — the 18 on file: 2 under 10k, 1 10k–20k, 2 20k–30k, 2 30k–40k, 2 40k–50k, 3 50k–60k, 1 60k–70k, 5 100k–150k.

Median mileage by component

Component	Reports	Median miles	Vs same age
Engine	15	50,000	1.51×

Vs same age is this model year’s median for the system divided by the median of every 2023-model-year complaint about the same system, all makes: under 1× means owners of this car reported it at lower mileage. Here, owners reported later: engine (1.51×). Which systems go early across the whole fleet: the component study.

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.

This PI is to instruct dealer on diagnostic procedures that need to be completed prior to replacing a radio or IPC display

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.

A rate appears only where at least 200 inspections stand behind it. “Every 2023 vehicle” is every 2023 model-year car, SUV and pickup inspected in the same window, all makes.

NHTSA has posted 4 recall campaigns for the 2023 Chevrolet Suburban. The most serious on file is 25V274000, covering Engine And Engine Cooling. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2023 Chevrolet Suburban?

NHTSA gave the 2023 Chevrolet Suburban 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 C (79/100) on its recall record, which is a different question from crash protection.

What is the fuel economy of the 2023 Chevrolet Suburban?

Across the 6 EPA-rated configurations of the 2023 Chevrolet Suburban, the best EPA combined figure is 23 mpg. Figures are the EPA's own, per configuration, and every one is listed above.

What do owners complain about on the 2023 Chevrolet Suburban?

Owners have filed 148 complaints with NHTSA about the 2023 Chevrolet Suburban, most often about engine, power train, electrical system. Of those, 1 involved a crash, 4 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 2023 Chevrolet Suburban?

The EPA smog rating for the 2023 Chevrolet Suburban 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, Federal Tier 3 Bin 125, Federal Tier 3 Bin 50 — which the table above lists per configuration.

Are there service bulletins for the 2023 Chevrolet Suburban?

The manufacturer has filed 1279 service bulletins and related communications with NHTSA for the 2023 Chevrolet Suburban, most often covering electrical system, unknown or other, engine. The most recent is dated 2026-10-17. 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 2023 Chevrolet Suburban do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2023 Chevrolet Suburban failed the emissions check on 3.0% of first inspections — higher than the 1.6% for every 2023 model-year vehicle inspected; and the safety inspection on 0.88% (every 2023 vehicle: 1.1%). 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.

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	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	4	NHTSA recall campaigns	A complete federal register: every campaign covering this model year, with severity and advisory flags.
Owner complaints	148	NHTSA complaint database	Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold.
Crash ratings	2 tested	NHTSA NCAP	Only the configurations NHTSA chose to crash-test, which is never all of them.
Service bulletins	1279	NHTSA manufacturer communications	Everything the manufacturer told its dealers about a defect or malfunction, short of a recall.
Investigations	4	NHTSA Office of Defects Investigation	Open and closed defect investigations, with the agency's own narrative.
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	12 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.
