| SLC300 | 6 / 10 | LEV-III ULEV125 / Federal Tier 3 Bin 125 | All 50 states (federal, all altitudes); California and states following California standards | — |
| AMG SLC43 | 7 / 10 | Federal Tier 3 Bin 70 | All 50 states (federal, all altitudes) | — |
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.
Factory warranty running out?
The 2016 Mercedes-Benz SLC-Class is in the years where transmission, electronics and drivetrain repairs land on the owner. What an extended plan does and does not cover is worth reading before a dealer quotes you one.

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.
NHTSA defect investigations
Air Bags:Frontal:Passenger Side:Inflator Module — Desiccated Air Bag Inflator Rupture open
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf. Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a subst

Whether any of this applies to one specific SLC-Class
A campaign covers a build range, not a model year, so two identical-looking cars from 2016 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 2016 Mercedes-Benz SLC-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 complaintsCodes 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.

| C350E C350E on Mercedes-Benz → | Manufacturer-defined — the meaning is set by the automaker, not the standard. | Engine | 1 bulletin |
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.

SLC-Class by model year
all years, side by side →Common questions about the 2016 SLC-Class
Source: EPA, NHTSA and manufacturer press kitsDoes the 2016 Mercedes-Benz SLC-Class have any recalls?
NHTSA has posted 1 recall campaign for the 2016 Mercedes-Benz SLC-Class. The most serious on file is 17V308000, covering Electronic Stability Control (Esc). Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2016 Mercedes-Benz SLC-Class?
NHTSA has not published a crash-test rating for the 2016 Mercedes-Benz SLC-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 2016 Mercedes-Benz SLC-Class?
Across the 2 EPA-rated configurations of the 2016 Mercedes-Benz SLC-Class, the best EPA combined figure is 27 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
How clean is the 2016 Mercedes-Benz SLC-Class?
The EPA smog rating for the 2016 Mercedes-Benz SLC-Class runs 6 to 7 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 — Federal Tier 3 Bin 125, Federal Tier 3 Bin 70, LEV-III ULEV125 — which the table above lists per configuration.
Are there service bulletins for the 2016 Mercedes-Benz SLC-Class?
The manufacturer has filed 66 service bulletins and related communications with NHTSA for the 2016 Mercedes-Benz SLC-Class, most often covering power train, exterior lighting, 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.
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 | 2 configurations | EPA certification records | Every configuration the EPA certified for sale, with its own test figures. |
| Emission certificates | 2 configurations | EPA emission certificates | Smog rating, standard and the sales area that decides where the car can be sold new. |
| Recalls | 1 | NHTSA recall campaigns | A complete federal register: every campaign covering this model year, with severity and advisory flags. |
| 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. |

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.
