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.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

NHTSA campaign 22V903000 reported Dec 8, 2022 General Motors, LLC the full filing, and every vehicle covered →

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 CT4

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. Cadillac publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.

The problem first arose in June 2023 with a different car, 2022 CT4V VIN . I was driving and suddenly, all the dashboard lights went on and the brakes stopped working. There was no pressure on the pedal. I was able to roll to a stop without incident.

Service Brakes Jan 10, 2024 NHTSA owner report · ODI 11564719

The vehicle shut off while driving on the feeder of the highway. Vehicle was no longer responsive and had to be towed to Central Cadillac of Houston; where later it was determined that the vehicle needed a new engine. The Vehicle is a 2023 with less than 5,000 miles on it.

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.

New York’s emissions test on these model years is an on-board diagnostics check: it fails a car whose check-engine light is on or whose self-tests have not finished. First inspections only, so a car that failed and came back is counted once; private and special plates, not taxis, livery or commercial plates. 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. This is the state’s record of test results, not a reliability score by itself. Source: New York State Department of Motor Vehicles, Vehicle Inspections (data.ny.gov, Open NY terms).

Common questions about the 2023 CT4

Source: EPA, NHTSA and manufacturer press kits

Does the 2023 Cadillac CT4 have any recalls?

NHTSA has posted 1 recall campaign for the 2023 Cadillac CT4. The most serious on file is 22V903000, covering Exterior Lighting. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2023 Cadillac CT4?

NHTSA has not published a crash-test rating for the 2023 Cadillac CT4 yet. On the recall record WhichTrim grades it A (97/100), which measures open and severe recalls rather than crash protection.

What is the fuel economy of the 2023 Cadillac CT4?

Across the 8 EPA-rated configurations of the 2023 Cadillac CT4, the best EPA combined figure is 27 mpg. Figures are the EPA's own, per configuration, and every one is listed above.

What do owners complain about on the 2023 Cadillac CT4?

Owners have filed 3 complaints with NHTSA about the 2023 Cadillac CT4, most often about power train, engine, electrical system. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.

How clean is the 2023 Cadillac CT4?

The EPA smog rating for the 2023 Cadillac CT4 runs 5 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 — California LEV-III SULEV30, California LEV-III ULEV50, California LEV-III ULEV70, Federal Tier 3 Bin 30, Federal Tier 3 Bin 50, Federal Tier 3 Bin 70 — which the table above lists per configuration.

Are there service bulletins for the 2023 Cadillac CT4?

The manufacturer has filed 554 service bulletins and related communications with NHTSA for the 2023 Cadillac CT4, most often covering unknown or other, electrical system, engine. The most recent is dated 2026-10-07. 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 Cadillac CT4 do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2023 Cadillac CT4 failed the emissions check on 4.3% of first inspections — higher than the 1.6% for every 2023 model-year vehicle inspected; and the safety inspection on 3.5% (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.

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.
