Expert verdict
Body & chassis: 2.6× the national share
Body & chassis accounts for 14.6% of everything recorded on the 2001 Chevrolet Gmc Blazer V6, against 5.6% nationally — 9.0 points above. Brakes are still the single largest share at 19.9%, but at 20.9% nationally that one is ordinary. Look underneath for corrosion near the jacking points and suspension mounts; surface rust is normal, flaking metal is not.
- 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 73.3% and this one manages 77.4% — 4.1 points ahead of what its age and mileage predict.
- Based on a small sample. 53 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

What fails a 2001 Blazer V6
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 2001 Blazer V6
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 battery 5.7% of tests
“battery(ies) insecure”
Check the battery is secure and its terminals are clean and tight — a loose battery is a fail on its own, and a weak one shows up as slow cranking on a cold morning.
-
Check the lights 5.7% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
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 corrosion 3.8% of tests
“chassis condition or chassis has excessive corrosion, seriously affecting its strength within 30cm of a body mounting”
Look under the sills, around the jacking points and where the suspension mounts meet the body. Flaking, holed or crumbly metal fails; a brown stain on sound metal does not.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
