The Jcb Unknown has an overall MOT pass rate of 98.4% across 793 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common problems on the Jcb Unknown are obligatory mirror missing (2 recorded failures), stop lamp not working near and offside (1), and fog lamp missing (1). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
On the safety side, the most frequently flagged dangerous fault is tyre tread pattern not visible over the whole tread area when minimum depth required is 1.0mm both. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Jcb Unknown with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.
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.
