An analysis of 43,637 real DVSA MOT tests on the Smart Fortwo Passion Mhd Auto — what fails, how often, and how that compares to every other car on UK roads.

Where the Smart Fortwo Passion Mhd Auto fails its MOT

The single biggest MOT failure point on the Smart Fortwo Passion Mhd Auto is engine mounting/bracket severely damaged or det... — this model is 55 times more likely to fail on this item than the average car on UK roads.

Bodywork failures usually mean structural corrosion — not cosmetic rust, but rot that affects the car's structural integrity. Check sills, subframes, and chassis rails carefully, especially on older examples.

Other notable weak points include anti-roll bar links worn (12x the fleet average), headlight fault (13x the fleet average), significant brake effort recorded with no brake... (11x the fleet average), and tyre valve seriously damaged or misaligned (9.2x the fleet average). These ratios compare the Smart Fortwo Passion Mhd Auto's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.

The failures span 5 categories: Bodywork, Suspension, Lights & Electrics, Brakes, Tyres. If you're inspecting a Smart Fortwo Passion Mhd Auto before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.

How failures change with mileage

The Smart Fortwo Passion Mhd Auto's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.

Under 60,000 miles

At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.

For the Smart Fortwo Passion Mhd Auto specifically, the DVSA data shows the most common failures at this mileage are engine mounting/bracket severely damaged or det... (55x the average) and headlight fault (13x). anti-roll bar links worn (12x) and significant brake effort recorded with no brake... (11x) also appear frequently.

60,000 to 100,000 miles

This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.

For the Smart Fortwo Passion Mhd Auto specifically, the DVSA data shows the most common failures at this mileage are engine mounting/bracket severely damaged or det... (29x the average) and tyre valve seriously damaged or misaligned (6.1x). anti-roll bar links worn (5.2x) and anti-roll bar links worn also appear frequently.
