2017 Buick Cascada Safety Report

The 2017 Buick Cascada presents a generally strong safety profile based on NHTSA data, achieving an impressive 5-star overall safety rating. It performed exceptionally well in side impact tests, earning a perfect 5 stars, and received solid 4-star ratings for both frontal crash and rollover resistance. This indicates a robust design for occupant protection in various collision scenarios. However, despite its strong crash test performance, the vehicle has accumulated 12 NHTSA complaints, with a notable pattern emerging around engine-related issues, specifically concerning the PCV valve and camshaft cover. These complaints, while not linked to crashes, fires, or injuries, suggest potential reliability concerns with specific engine components. Analysis of the 12 complaints reveals that ENGINE and ENGINE AND ENGINE COOLING components account for 7 of the total complaints (5 for ENGINE, 2 for ENGINE AND ENGINE COOLING). Several complaints detail issues with the PCV valve, often integrated into the valve cover, leading to rough idle, check engine lights, and significant repair costs at relatively low mileages (e.g., 42,000-46,200 miles). This suggests a design or manufacturing vulnerability in this specific engine system. Additionally, there are multiple complaints regarding the convertible top's rear window separating from the fabric, indicating a potential durability issue with the convertible mechanism. Crucially, the 2017 Buick Cascada has no open recalls, which is a positive indicator regarding widespread, safety-critical defects identified by the manufacturer or NHTSA. While the engine issues are concerning for owners, they have not triggered a recall for this specific model year, although some owners referenced special coverage adjustments for similar issues in other model years. The absence of crashes, fires, or injuries in the complaint data further supports the vehicle's overall structural safety in real-world incidents, aligning with its high crash test ratings. The primary safety concerns appear to be related to component reliability rather than immediate crashworthiness.

Our recommendation: The 2017 Buick Cascada offers excellent crash safety, but potential buyers should be aware of documented engine PCV valve issues and convertible top window separation, which can lead to costly repairs. Consider a pre-purchase inspection focusing on these known problem areas.
