The Mercedes-Benz B-Class has long been recognized for its blend of practicality and premium features, appealing to families and urban drivers alike. Introduced as a compact MPV, the B-Class stands out with its spacious interior, advanced technology, and a reputation for comfort. As the years progress, understanding the reliability of specific model years through MOT inspection data provides valuable insights for potential buyers and current owners.

In terms of general reliability, the B-Class has performed well against the average of similar vehicles in its class. For instance, the 2019 model recorded 77 defects per 100 inspections, significantly lower than the average of 106 defects, marking a 28% improvement. The trend continued in 2020 with 68 defects compared to an average of 90, showcasing a consistent reliability advantage during these years.

The 2021 model saw a marked improvement, with defects dropping to just 47 per 100, outperforming the average of 79 by a substantial 40%. This positive trajectory continued into 2022, where the B-Class recorded only 33 defects, again below the average of 70, representing a remarkable 53% reduction. This consistent decline in defects suggests that Mercedes-Benz has effectively addressed issues over the years, enhancing the model's overall reliability.

Recurring issues across these years primarily involve tyre condition and brake wear, which, while common across many vehicles, indicate that regular maintenance is crucial. Problems such as inadequate tyre tread depth and worn brake pads were frequently reported, but these issues are not unique to the B-Class. Overall, the data reflects a strong performance in reliability, especially in the latter model years.
