2021 Mercedes-Benz Cla-Class Safety Report

The 2021 Mercedes-Benz CLA-Class exhibits a relatively low number of NHTSA complaints, with only 5 total reported incidents. This includes 1 crash, 1 injury, 0 fires, and 0 deaths, suggesting a generally safe vehicle in terms of severe incident frequency. However, the lack of official NHTSA crash test ratings (Overall, Frontal, Side, Rollover are all N/A) means its performance in controlled crash scenarios is unassessed by this agency, which is a significant gap in its safety profile. Despite the low complaint volume, some reported issues are severe, such as a ball joint failure leading to wheel detachment and multiple instances of sudden loss of power/acceleration. Common complaint patterns, though based on a small sample, point to diverse issues rather than a single dominant problem. Components like EXTERIOR LIGHTING, UNKNOWN OR OTHER, POWER TRAIN/VEHICLE SPEED CONTROL/ENGINE, VEHICLE SPEED CONTROL/FUEL/PROPULSION SYSTEM, and SUSPENSION each have one complaint. This spread indicates that while no single component is a widespread failure point, critical safety systems like the powertrain and suspension have been implicated in serious incidents. For example, one complaint details a front right ball joint breaking at 25-30 mph, causing the wheel to detach and the car to crash into a parked vehicle, resulting in an injury. The recall history for the 2021 Mercedes-Benz CLA-Class shows 0 recalls, which is positive in that no widespread manufacturing defects requiring manufacturer-initiated fixes have been identified by NHTSA. However, the absence of recalls does not negate the severity of individual reported failures. The incidents of sudden loss of power on the highway, reported on four separate occasions, and the exploding sunroof, while isolated, highlight potential quality control issues that could impact safety. The lack of crash test data makes it difficult to fully assess the vehicle's occupant protection capabilities in a collision. Overall, the 2021 Mercedes-Benz CLA-Class presents a mixed safety picture. While the low complaint count and absence of recalls are favorable, the lack of NHTSA crash test ratings is a significant unknown. The nature of some complaints, particularly those involving critical mechanical failures like ball joint detachment and sudden power loss, suggests that even with low frequency, these issues can be severe and directly impact vehicle control and occupant safety. Buyers should be aware of these potential, albeit rare, critical failures.

Our recommendation: While the 2021 Mercedes-Benz CLA-Class has a low complaint volume and no recalls, the absence of NHTSA crash test ratings and reports of critical mechanical failures like ball joint detachment and sudden power loss warrant caution; consider a pre-purchase inspection focusing on suspension and powertrain components.
