Ford Grand C-Max: MOT pass rate and reliability data

The Ford Grand C-Max fails its first MOT more often than the average UK car, by 2.9 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 36,037 individual Ford Grand C-Max tests. Nothing here is an estimate or a survey.

The numbers

First-time pass rate73.8%
UK national average76.7%
Difference-2.9 points
Tests analysed36,037
Average mileage at test79,941 miles
Average year of manufacture2014
Reliability rank1,650 of 2,005 models

What this means if you are buying one

A 73.8% first-time pass rate means roughly 26 in every 100 Ford Grand C-Max presented for MOT fail on the first attempt. That is worse than average, so budget for remedial work and treat a fresh 12-month MOT as a genuine selling point rather than a given. The average Ford Grand C-Max tested had covered 79,941 miles and was built around 2014.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Ford Grand C-Max sits 2.9 points below the national average, ranked 1,650 of 2,005 models. On one bought as repairable salvage, assume the mechanical side needs more than the visible accident damage, and pad your repair estimate accordingly.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Ford Grand C-Max rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see the median recorded closing bid for a damaged Ford Grand C-Max: £450 at UK salvage auction, from 11 ended listings, not independently confirmed sales.
