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.
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 2019 Buick Cascada, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

In owners' own words
Filed with NHTSA by the people who own these cars, one per problem area. Quoted as written, with anything identifying removed.
The contact owns a 2019 Buick Cascada. The contact stated that the convertible top rear glass had significantly detached from the top cover material. The vehicle was taken to the dealer, where it was determined that the entire convertible top needed to be replaced. The vehicle was not repaired.
I am reporting the malfunction and separation of the rear window from the cover. This is a safety issue as there is the potential for it to come off while driving and possibly causing an accident. It started small, but has grown to almost 12 inches. I have not yet found anyone who has the capacity (or desire) to fix this.
The contact owns a 2019 Buick Cascada. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle lost motive power. In addition, the transmission and engine failure warning lights were illuminated.
The contact owns a 2019 Buick Cascada. The contact stated that the rear windshield was separating from the convertible top plastic frame. The contact stated that the rear glass was pushing upward and out of the frame.
The contact owns a 2019 Buick Cascada. The contact stated while driving at an undisclosed speed during a rainstorm, water started entering the vehicle through the rear windshield. The contact stated that the rear windshield was separating from the seal. No warning lights were illuminated.

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

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.

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 | 1 configurations | EPA certification records | Every configuration the EPA certified for sale, with its own test figures. |
| Emission certificates | none | EPA emission certificates | The EPA published no certificate we could match to a configuration on this page. |
| Recalls | none | NHTSA recall campaigns | No campaign has been filed. Because the register is complete, an empty row here means there is nothing to find — not that we are missing it. |
| Owner complaints | 5 | NHTSA complaint database | Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold. |
| Crash ratings | 1 tested | NHTSA NCAP | Only the configurations NHTSA chose to crash-test, which is never all of them. |
| Service bulletins | 539 | NHTSA manufacturer communications | Everything the manufacturer told its dealers about a defect or malfunction, short of a recall. |
| Investigations | none | NHTSA Office of Defects Investigation | No defect investigation has been opened. |
| Driver-assist crash reports | none | NHTSA Standing General Order 2021-01 | No report has been filed. Only entities named in the order report, and only crashes they hear of — so this is also what an unequipped car, or a manufacturer without telematics, looks like. |
| Specifications filed with NHTSA | 8 fields | NHTSA vPIC, decoded from VIN patterns | What the manufacturer filed under the federal VIN rule — a configuration, not the full trim ladder. |
| Trims, pricing & equipment | none | Manufacturer press kit | We have not transcribed a press kit for this model year yet. This is our gap, not the manufacturer's — the one row here where an empty cell means we are behind. |

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.
