Expert verdict
Brakes: 1.5× the national share
Brakes make up 31.2% of everything recorded on the 2010 Chrysler 300, against 20.9% nationally — 10.3 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- When it fails, it costs. Only 22% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2010 300
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 2010 300
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 5.9% 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 the suspension joints 5.7% of tests
“ball joint dust cover severely deteriorated”
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.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2010 300 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £27–£74 — and 22% of those repairs are parts that cost under £30.

| Brake discs in such a condition that it is seriously weakened Brakes | Advisory | 20.2% | £45–110 |
