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 CLS-Class

A campaign covers a build range, not a model year, so two identical-looking cars from 2020 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 2020 Mercedes-Benz CLS-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.

Manufacturer-defined — the meaning is set by the automaker, not the standard.Engine3 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 2020 CLS-Class

Source: EPA, NHTSA and manufacturer press kits

Does the 2020 Mercedes-Benz CLS-Class have any recalls?

NHTSA has posted 8 recall campaigns for the 2020 Mercedes-Benz CLS-Class, 1 of them rated critical. The most serious on file is 24V445000, 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 2020 Mercedes-Benz CLS-Class?

NHTSA has not published a crash-test rating for the 2020 Mercedes-Benz CLS-Class yet. On the recall record WhichTrim grades it F (59/100), which measures open and severe recalls rather than crash protection.

What is the fuel economy of the 2020 Mercedes-Benz CLS-Class?

Across the 3 EPA-rated configurations of the 2020 Mercedes-Benz CLS-Class, the best EPA combined figure is 26 mpg. Figures are the EPA's own, per configuration, and every one is listed above.

What are the dimensions of the 2020 Mercedes-Benz CLS-Class?

Transport Canada measured it at 196.5 in long, 73.2 in wide (body, without mirrors), 57.1 in tall, on a 115.7 in wheelbase. Curb weight: 4,255–4,456 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 2020 Mercedes-Benz CLS-Class?

Owners have filed 6 complaints with NHTSA about the 2020 Mercedes-Benz CLS-Class, most often about electrical system, engine, wheels. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.

How clean is the 2020 Mercedes-Benz CLS-Class?

The EPA smog rating for the 2020 Mercedes-Benz CLS-Class is 6 out of 10. 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 ULEV50, Federal Tier 3 Bin 50 — which the table above lists per configuration.

Are there service bulletins for the 2020 Mercedes-Benz CLS-Class?

The manufacturer has filed 352 service bulletins and related communications with NHTSA for the 2020 Mercedes-Benz CLS-Class, most often covering electrical system, power train, equipment. 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.

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.
