This 2015 BMW 420D Gran Coupé has a first-time pass rate of just 55.4%, significantly below the UK average of 80%, which signals meaningful reliability concerns for buyers considering this model. The good news is that dangerous defects are absent from this dataset, so while these cars need attention, they're not failing on safety-critical items.
At 83,111 miles median, these vehicles have covered typical mileage for their age, yet they're still arriving at MOT with an average of 0.26 failures per car—a modest figure that suggests issues are spread across the fleet rather than concentrated. Before purchasing, have a pre-buy inspection focus on the diesel engine and transmission, as the low pass rate points to wear patterns in those areas rather than catastrophic design flaws.
