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

Structure:Body:Roof And Pillars — Front Roof Panel Detachment closed

On January 8, 2021, after ongoing review with Mercedes Benz, the National Highway Traffic Safety Administration (NHTSA) Office of Defects Investigation (ODI) opened PE21-001 to assess allegations of front roof panel detachments while driving at highway speeds in certain 2015 Mercedes-Benz (Mercedes) C-Class vehicles. The subject front roof panel is a stationary panel composed of polycarbonate and is attached to the vehicle via adhesive at the time of manufacture. The panel is found on subject vehicles equipped with panoramic sunroofs. Over time, the subject panels may exhibit cosmetic degradation leading to replacement of the panel, a procedure which entails: removal of the old panel and adh

Whether any of this applies to one specific CLA-Class

A campaign covers a build range, not a model year, so two identical-looking cars from 2017 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 2017 Mercedes-Benz CLA-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.

How safe is the 2017 Mercedes-Benz CLA-Class?

NHTSA has not published a crash-test rating for the 2017 Mercedes-Benz CLA-Class yet. On the recall record WhichTrim grades it F (46/100), which measures open and severe recalls rather than crash protection.

What is the fuel economy of the 2017 Mercedes-Benz CLA-Class?

Owners have filed 28 complaints with NHTSA about the 2017 Mercedes-Benz CLA-Class, most often about electrical system, engine, air bags. Of those, 2 involved a crash, 2 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 2017 Mercedes-Benz CLA-Class?

The EPA smog rating for the 2017 Mercedes-Benz CLA-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, LEV-III ULEV70 — which the table above lists per configuration.

Are there service bulletins for the 2017 Mercedes-Benz CLA-Class?

The manufacturer has filed 177 service bulletins and related communications with NHTSA for the 2017 Mercedes-Benz CLA-Class, most often covering electrical system, exterior lighting, power train. The most recent is dated 2026-09-22. 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.
