This 2021 BMW 545e xDrive is underperforming on MOT reliability: a 73.7% first-time pass rate sits well below the UK average of 80%, and nearly a quarter of vehicles (23.5%) have recorded dangerous defects—a genuine concern for a car in this price bracket. The petrol-electric hybrid powertrain appears to be generating problems faster than conventional alternatives.

At just over 34,000 miles median, these cars are lightly used for their age, yet they're still racking up 0.33 failures and 0.6 advisories per vehicle on average—suggesting mechanical issues emerge quickly rather than through hard use. Before committing to one, get a full pre-purchase inspection by an independent BMW specialist, particularly focusing on hybrid system health and electrical components, since the MOT data hints at systemic weakness rather than isolated problems.

We have limited data for the 2021 BMW 545e Xdrive M Sport Auto — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
