Expert verdict
Lamps & electrics: 1.7× the national share
Lamps & electrics make up 20.4% of everything recorded on the 2004 Jeep Wrangler, against 12.2% nationally — 8.2 points above. Suspension is still the single largest share at 23.3%, but at 21.0% nationally that one is ordinary. Walk round the car with the lights on before the test: bulbs, indicators and number-plate lamps are the cheapest failures to prevent and among the most common.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 72.2% and this one manages 79.8% — 7.6 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 65% of the repairs this model fails on cost under £30 in parts. The pass rate matters less than what a bad afternoon at the test centre actually costs you.

What fails a 2004 Wrangler
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2004 Wrangler
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 3.8% of tests
“rear fog lamp not working”
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.
-
Check the suspension joints 2.7% of tests
“pins and bushes pin or bush excessively worn”
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.
-
Check the windscreen 1.9% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
