The Sym Aj has an overall MOT pass rate of 78.6% across 430 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common failure point is stop lamp does not illuminate immediately a brake applies with 3 recorded occurrences. Check for this on any test drive or pre-purchase inspection.
On the safety side, the most frequently flagged dangerous fault is tyre tread depth is below minimum requirements of 1.0mm. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Sym Aj with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.
A typical Sym Aj owner drives around 653 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
In terms of longevity, most Sym Aj models stay on UK roads for around 13 years. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
