This 2009 E350 BlueEfficiency is a significant reliability concern—it passes its MOT first time just 41.6% of the time, nearly half the UK average of 80%. The diesel variant (which makes up 213 of the 215 vehicles analysed) performs identically poorly at 41.2%, suggesting the problem is endemic to this model rather than fuel-type specific.
With a median mileage of 112,190 km for a 15-year-old car, these examples are running fairly hard, and they're clearly suffering for it: owners face an average of 0.97 failures per test. Before buying one, have a pre-purchase inspection by a Mercedes specialist and budget for imminent repair costs—nearly 6 in 10 will need work to pass their next MOT.
