What this shows

These are MOT fail items that coil spring replacement fixes, as testers found them on the day of the test. Repairs done between MOTs never show up in MOT data, and mileage is not taken into account, so this is not how often owners pay for the repair.

By age

Fail items fixed by coil spring replacement, per 100 MOT tests, against cars of the same age and the same fuel mix. The model figure is a floor: DVSA data lists each model’s 25 most recorded items per age, and an item outside that list is counted as zero. The comparison figure is a ceiling: an item too rare to be listed for a fuel is counted at its highest possible value.

How we decide: a page exists only when the main generation’s rate, weighted to its own mix of ages and fuels, is at least 1.5 times the rate of cars of the same ages and fuel, from at least 50,000 tests at 3 or more ages, with at least 100 expected items.

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.

What garages charge

Prices are national. They are not specific to the Mazda 3.

No public source records the price of this whole job, and the time it takes varies from car to car, so we do not publish a single figure. Garages charge by the hour, so ask for a quote that lists labour time and parts. The rates below are what UK garages charge per hour.

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.
