Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV) filed May 7, 2024
NHTSA complaint #1989686 (ODI reference 11587414) concerns a 2017 BUICK CASCADA and was filed on May 7, 2024. The owner reports the failure occurred on May 2, 2024. The vehicle had 45,928 miles on the odometer at the time of the incident. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as engine and engine cooling:exhaust system:emission control:crankcase (pcv), one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same BUICK CASCADA cohort independently describe similar engine and engine cooling:exhaust system:emission control:crankcase (pcv) failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2017 BUICK CASCADA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2017 Buick Cascada. The contact stated that while driving at various speeds, there was an abnormal squealing sound coming from the vehicle. There was no warning light illuminated. The vehicle was taken to an independent mechanic where it was discovered that the diaphragm inside the PCV (Positive Crankcase Ventilation) valve had ruptured. The part was replaced by the mechanic. Upon investigation, the contact discovered that the failure was covered under warranty through the manufacturer. The manufacturer was notified of the failure but denied the request for a reimbursement since the vehicle was not serviced at the dealer. The vehicle was repaired. The failure mileage was 45,928.
