Mercedes-Benz A-Class Common Problems

ELECTRICAL SYSTEM

Owners of the 2019 Mercedes-Benz A-Class frequently report issues with the vehicle's electrical system, particularly involving display screens and the MBUX Hard Disk Drive. Several complaints describe blacked-out screens on the driver's side and central control display, with repair costs quoted as high as $7,000, and some owners note these issues occurred after automatic updates. The MBUX system failure reportedly leads to safety concerns such as disabled rear cameras and sudden loud audio, which can distract drivers. Additionally, problems with the rear view camera displaying mirrored images are noted, creating confusion during reversing. These electrical issues appear at various mileages, with some reports as early as 738 miles, and may pose safety risks due to impaired visibility and driver distraction.

Owners of the 2018 Mercedes-Benz A-Class frequently report issues with the transmission, particularly difficulty shifting gears. Complaints commonly mention an inability to shift from Park to other gears, and from Drive to Reverse, often requiring the engine to be restarted to resolve the issue temporarily. These problems are noted to occur intermittently and seem to become more frequent over time, with some reports indicating recurrence for several years. One owner reports a crash related to the vehicle lunging forward unexpectedly while stopped. Additionally, some owners describe violent jerking when downshifting and unintended rolling when the vehicle is shut off in Drive. These issues are typically observed after several years of ownership or around 60,000 miles, suggesting potential concerns for used car buyers regarding reliability and safety.
