The 2019 Mercedes-Benz A Class has 6 recalls, the most serious involving front subframe corrosion that can cause suspension or steering components to detach, leading to a loss of steering control.
A misrouted air conditioning drain hose can allow water to leak into the cabin and short-circuit electrical components, potentially disabling the airbag control unit, cutting fuel pump operation, or preventing the engine from starting. There is also a separate airbag concern: the driver's front airbag module may not be properly secured and can pull away from its mount in a crash, preventing it from deploying correctly. On the visibility side, a software issue can delay the rearview camera image when shifting into reverse, and the adaptive high-beam assist system may fail to dim the headlights when oncoming traffic is detected, creating glare for other drivers. A final recall addresses windshield wipers that were set to clear a slightly smaller area of glass than regulations require, though the regulator notes this is unlikely to affect visibility in practice.
