Summary
The Mercedes-Benz A Class has 7 recalls covering the 2019-2022 model years, with the most serious affecting 2019 vehicles where the front subframe can corrode until suspension or steering components detach, causing a loss of steering control. The 2022 model year has a single recall for headlamps that were not aimed correctly at the factory, which can reduce the driver's forward visibility and throw glare into oncoming traffic. Across the 2019 model year, three additional issues stand out. A misrouted air conditioning drain hose can allow water to migrate inside the cabin and short circuit nearby electronics, potentially disabling the airbag control unit, knocking out the fuel pump, or leaving the engine with reduced power or unable to start. The driver-front airbag module on some 2019 vehicles may not be properly secured to its mount, meaning it can shift or separate in a crash and fail to deploy correctly. There is also a software fault on 2019 vehicles that can delay the rearview camera image appearing after the driver shifts into reverse, reducing visibility while backing up. Two lower-severity issues round out the 2019 recall picture: the adaptive high-beam assist camera software may not detect oncoming vehicles and automatically dip the beams, though drivers can override this by switching to manual light mode, and some 2019 vehicles left the factory with the driver's windshield wiper slightly under-adjusted, covering a marginally smaller arc than regulations specify.
