|---|---|
| Lamps, reflectors and electrical equipment | 40% |
| Suspension | 17% |
| Brakes | 17% |
| Steering | 14% |
| Noise, emissions and leaks | 11% |

Newest model year first. Only years with at least 50 recorded tests are listed.
These checks follow this Smart Roadster Speedsilver's own most-recorded failure strings, starting with what a tester is most likely to flag on a Smart Roadster Speedsilver.
the suspension joints — “track rod end ball joint dust cover damaged or deteriorated,”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
the exhaust and emissions — “emissions not tested unable to be completed”
Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.
the lights — “headlamp not working on dipped beam”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Derived from the DVSA failure strings testers recorded for the Smart Roadster Speedsilver. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
