This 2011 Smart ForTwo Passion CDI diesel struggles at MOT time: a 73% first-time pass rate sits 7 percentage points below the UK average, and a concerning 32% of these cars have been flagged with dangerous defects—nearly double the typical rate. Buyers should treat this as a red flag for structural or safety issues lurking in the used market.

At just under 52,000 miles median mileage, these are relatively low-mileage examples for their age, yet they're still averaging 2.26 failures and 9.5 advisories per test—suggesting inherent reliability weaknesses rather than wear-and-tear. Have a pre-purchase inspection focus on brake systems, suspension geometry, and corrosion, as the dangerous defect rate hints at deeper engineering or build-quality problems specific to this model and engine combination.

We have limited data for the 2011 Smart Fortwo Passion CDI 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.
