| Inspection section | Share of failures |
|---|---|
| Brakes | 33% |
| Lamps, reflectors and electrical equipment | 13% |
| Body, chassis, structure | 13% |
| Identification of the vehicle | 13% |
| Suspension | 13% |
| Road Wheels | 7% |
| Visibility | 7% |
Shares are over the Lhy 300ATV's recorded defect strings, merged across its year pages.

Testers recorded "Decelerometer (sp) efficiency less than 50% of the required value" (4.8%), "Gradient tester (sp) efficiency below requirements" (1.6%), "Hand lever has insufficient reserve travel" (1.6%) among the Lhy 300ATV's brakes faults.
Around 13% of the recorded Lhy 300ATV failures fall in the Lamps, reflectors and electrical equipment section of the MOT inspection manual. Testers recorded "Headlamp aim too low" (1.6%), "Position lamp not working" (1.6%) among the Lhy 300ATV's lamps, reflectors and electrical equipment faults.
Around 13% of the recorded Lhy 300ATV failures fall in the Body, chassis, structure section of the MOT inspection manual. Testers recorded "Joints constant velocity boot severely deteriorated" (3.2%) among the Lhy 300ATV's body, chassis, structure faults.
The descriptions below are the exact DVSA failure strings testers recorded most often for the Lhy 300ATV, each with how many of the model's 63 tests it was noted on.
The strongest Lhy 300ATV model year on record is 2020 (92.1% across 63 tests), and the weakest is 2020 (92.1%). Years with fewer than 50 recorded tests are excluded, so these are the years with enough MOT history to mean something.
| Year | Tests | Pass rate |
|---|---|---|
| 2020 300ATV | 63 | 92.1% |
Newest model year first. Only years with at least 50 recorded tests are listed.
These checks follow this Lhy 300ATV's own most-recorded failure strings, starting with what a tester is most likely to flag on a Lhy 300ATV.
the number plates — “registration plates missing”
Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.
the wheel bearings — “wheel bearings has excessive play”
Listen for a hum that rises and falls with speed and changes when you load one side in a bend. A noisy bearing is an easy pre-test diagnosis and an awkward surprise at the test station.
the lights — “headlamp aim too low”
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 Lhy 300ATV. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
92.1% of the 63 recorded Lhy 300ATV MOT tests ended in a pass, +11.1 percentage points above the national average. 91.5% of those passed on the first attempt.
2020 is the strongest Lhy 300ATV year on record at 92.1%, while 2020 is the weakest at 92.1%. The year-by-year table below lists every model year with at least 50 recorded tests.
The most recorded Lhy 300ATV failures are "Decelerometer (sp) efficiency less than 50% of the required value" and "Joints constant velocity boot severely deteriorated" — together around 8% of tests, mostly in the Brakes section.
