The Mercedes B-Class has a mixed reputation for reliability, with recent models generally performing well but older models showing some recurring issues.
For the 2012-2019 models, the B-Class has been rated highly in reliability surveys, often topping its class with an impressive overall score of around 96%. However, these models have seen some common issues, particularly with non-engine electrical systems. Owners have reported problems with the engine management system, sat-nav, and ignition operation, which, while not widespread, are worth considering if you're looking at a used B-Class from this period.
In contrast, the older 2005-2012 models had more pronounced reliability challenges. Recurring issues included problems with electronic systems, seatbelt wear, and clogging of the particulate filter in diesel models. Mercedes-Benz worked to address these issues over time, but these older models still tend to have a lower reliability score compared to more recent versions.
Overall, the B-Class holds an average reliability index score of 145, with average repair costs around £515.43. This suggests that while the car is generally dependable, repairs can be on the expensive side. To mitigate these costs, following a strict maintenance schedule is essential. Doing routine maintenance and minor repairs yourself with the help of a detailed repair manual can be an effective way to keep your B-Class running smoothly and avoid high repair bills.
