Times recorded adds every DVSA code with this wording, so a test can record it more than once, for example on two wheels under separate codes.

What it means

This is an advisory: the car passes its MOT, and the tester is warning about the part. An advisory is something the tester noticed that could become a defect later. The car passes its MOT. The advice is to monitor the part and repair it if it gets worse.

When it gets worse, the tester records it as a fail: Drive shaft excessively worn.

The tester looks at the body and underside for corrosion and damage, especially near the points where suspension, steering and seat belts are mounted, and checks the exhaust, fuel system, drive shafts and towbar.

The tester fails the car when the part reaches the point the MOT inspection manual describes (section 6.1.7):

A transmission joint, belt or chain excessively worn

The DVSA codes counted on this page: the manual item and the defect text as DVSA records them. The heading above joins the two, as a certificate does; the tester also adds the position, such as nearside front.

Models that get it most

Each model generation is compared with cars of the same ages and fuel, so older and diesel models are not penalised for their age or fuel. Generations are never pooled.

Model generations with the highest rate as an advisory, against cars of the same ages and fuel. A model’s figure counts this defect only at ages where it is among that model’s 25 most recorded items, and as zero elsewhere, so it is a floor. Tests (n) are all the generation’s MOT tests at ages with at least 1,000 tests each; at least 5,000 in total.
Model	Per 100 MOTs, at least	Same ages and fuel	Times as often	Tests (n)	Ages
Jaguar XK	0.65	0.060	10.9	86,405	8 to 25
Jeep Cherokeefirst used before 2014	0.24	0.088	2.7	26,264	15 to 25

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.

Repair and cost

We do not map this defect to one repair job, because the fix depends on the cause. Garages charge by the hour, so ask for a quote that lists labour time and parts.

Local garage labour, per hour (65 shops)£78

Local garage, middle half£70 to £96

Main dealer labour, per hour (62 shops)£156

Main dealer, middle half£144 to £174

Median hourly rate charged for car repairs, from 1,058 local garage and 953 main dealer price quotes collected by the ONS, September 2025 to August 2026. The same shops are priced each month, so the number of shops is the real sample.
