2017 Mercedes-Benz C-Class Safety Report

The 2017 Mercedes-Benz C-Class presents a mixed safety picture based on NHTSA data. While there are no official NHTSA crash test ratings available for this specific model year, the vehicle has accumulated 249 complaints, including 12 crashes, 2 fires, and 16 injuries. A significant concern is the complete absence of recalls, which is unusual for a vehicle with this volume of complaints, especially given that some complaints directly reference issues covered by recalls for similar VINs or models (e.g., fuel smell, sunroof detachment). The most frequently reported component is the ENGINE, with 50 complaints, often related to check engine lights (P052E code) and strong gasoline smells, suggesting potential fuel system or crankcase ventilation issues. Another notable pattern involves SEAT BELTS (20 complaints) becoming stuck or inoperable, and STRUCTURE (17 complaints), particularly concerning spontaneous sunroof explosions or detachments, which are serious safety hazards. The lack of recalls addressing these recurring, potentially dangerous issues is a significant oversight. Despite the lack of formal crash test data, the high number of complaints related to critical safety components like the engine, seat belts, and structural integrity (sunroof) raises concerns. The 16 reported injuries and 12 crashes underscore that these issues are not merely inconveniences but can lead to hazardous situations. The recurring nature of problems like the P052E engine code and sunroof failures, as detailed in multiple complaints, indicates potential design or manufacturing flaws that have not been officially acknowledged or remedied through recalls. This suggests that owners may face significant out-of-pocket repair costs for known issues that could impact vehicle safety and reliability. In summary, while the 2017 Mercedes-Benz C-Class has no official safety ratings, the substantial volume of complaints, particularly concerning engine issues, seat belt malfunctions, and spontaneous sunroof failures, points to several unaddressed safety and reliability concerns. The complete absence of recalls for a vehicle with 249 complaints, including incidents of crashes and injuries, is a critical point for potential buyers to consider. The data suggests a pattern of recurring problems that could compromise occupant safety and vehicle integrity.

Our recommendation: Given the 249 complaints, including 16 injuries and 12 crashes, and the complete absence of recalls for recurring issues like seat belt failures and sunroof explosions, exercise extreme caution. A pre-purchase inspection by a trusted mechanic, specifically checking for engine codes (P052E), fuel system integrity, and seat belt functionality, is highly recommended.
