Certified for all fifty states, so it can be registered new anywhere in the U.S.

The smog rating scores tailpipe pollutants other than greenhouse gases, 1 (worst) to 10 (best), and is comparable only within a model year. The standard is the federal bin or California tier the configuration was certified to. Both come from the EPA certificate behind the window sticker.

Filed by the manufacturer with NHTSA under the federal vehicle-identification rule and decoded from the VIN pattern — not a manufacturer press kit, so it describes the configurations we could identify rather than every trim (seen: G580e, GLS450 4MATIC, GLS580 4MATIC). Figures for the trim you are looking at may differ.

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%.

Problem Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2024 GLE 350 4MATIC, 2025 GLE 450e 4MATIC, GLE 450 4MATIC Coupe, GLE 450 4MATIC, GLS 450 4MATIC, Maybach GLS 600 4MATIC, AMG GLE 53 4MATIC, AMG GLE 53 4MATIC Coupe, AMG GLE 63 S 4MATIC Coupe, and AMG GLS 63 4MATIC vehicles. The multi-purpose camera and the rearview mirror may be insufficiently attached to the windshield and may detach. Risk A detached mirror can reduce visibility for the driver. A detached camera can cause a loss of certain driving assistance systems, such as Active Lane Keeping Assist and Active Brake Assist. Either of these situations can increase the risk of a crash. Fix Dealers will replace the windshield and reinstall the multi-purpose camera and rearview mirror, free of charge. Owner notification letters were mailed June 27, 2025. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2025060001.

These are vehicle campaigns — the ones the automaker filed against this model. NHTSA also records equipment recalls, filed by a parts maker against a component (a tyre, a child seat, an aftermarket part), and those are not listed here or counted above. nhtsa.gov/recalls shows both for a VIN.

Whether any of this applies to one specific GLS-Class

A campaign covers a build range, not a model year, so two identical-looking cars from 2025 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Mercedes-Benz 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 2025 Mercedes-Benz GLS-Class, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

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.

Diagnostic trouble codes on file

Source: NHTSA manufacturer communications and complaints

Codes documented against this model year in the federal record. A code appearing here does not mean this vehicle will set it — it means the code is part of this nameplate-year's documented history.

Code	What it means	Most often filed under	Where it appears
U019F U019F on Mercedes-Benz →	Manufacturer-defined — the meaning is set by the automaker, not the standard.	Engine	4 bulletins

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.

Common questions about the 2025 GLS-Class

Source: EPA, NHTSA and manufacturer press kits

Does the 2025 Mercedes-Benz GLS-Class have any recalls?

NHTSA has posted 1 recall campaign for the 2025 Mercedes-Benz GLS-Class. The most serious on file is 25V325000, covering Visibility. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2025 Mercedes-Benz GLS-Class?

NHTSA has not published a crash-test rating for the 2025 Mercedes-Benz GLS-Class yet. On the recall record WhichTrim grades it A (92/100), which measures open and severe recalls rather than crash protection.

What is the fuel economy of the 2025 Mercedes-Benz GLS-Class?

Across the 4 EPA-rated configurations of the 2025 Mercedes-Benz GLS-Class, 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 2025 Mercedes-Benz GLS-Class?

Transport Canada measured it at 205.1–205.9 in long, 79.9 in wide (body, without mirrors), 71.7 in tall, on a 123.2 in wheelbase. Curb weight: 5,467–6,074 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 2025 Mercedes-Benz GLS-Class?

Owners have filed 10 complaints with NHTSA about the 2025 Mercedes-Benz GLS-Class, most often about engine, service brakes, electrical system. Of those, 2 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 2025 Mercedes-Benz GLS-Class?

The EPA smog rating for the 2025 Mercedes-Benz GLS-Class runs 4 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 SULEV30, California LEV-III ULEV70, Federal Tier 3 Bin 30, Federal Tier 3 Bin 70 — which the table above lists per configuration.

Are there service bulletins for the 2025 Mercedes-Benz GLS-Class?

The manufacturer has filed 392 service bulletins and related communications with NHTSA for the 2025 Mercedes-Benz GLS-Class, most often covering electrical system, power train, visibility/wiper. 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 2025 Mercedes-Benz GLS-Class do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2025 Mercedes-Benz GLS-Class failed the safety inspection on 0.71% of first inspections — higher than the 0.36% for every 2025 model-year vehicle inspected. 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

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.
