Expert verdict
Suspension: 1.5× the national share
Suspension accounts for 31.2% of everything recorded on the 2004 Chrysler Jeep Wrangler, against 21.0% nationally — 10.2 points above. Ask for the front and rear suspension to be checked on a ramp before you buy — worn bushes and broken springs are cheap to look at and expensive to discover at test time.
- 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 76.2% — 4.0 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 72% 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 8.9% 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 leaks 3.0% of tests
“steering box leaking oil”
Park on clean cardboard overnight. A few drips are an advisory; a steady patch under the engine, gearbox or a shock absorber is a fail. Have the source identified before the test rather than after.
-
Check the wipers and washers 3.0% of tests
“wipers does not clear the windscreen effectively”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
