Should I check the MOT history before buying a 2021 Volkswagen Id4 Max?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2021 VW ID4 Max is a solid performer, with a 90.8% first-time pass rate that sits well ahead of the UK average of 80%, though the 20.1% of vehicles that have recorded a dangerous defect is a borderline concern worth noting during any pre-purchase inspection. These are still young cars—averaging 34,714 miles—and they're showing it with only 0.28 failures per vehicle on average.

At 1.6 advisories per vehicle, owners are mostly encountering minor wear items rather than structural problems, which is reassuring for an electric car where the powertrain complexity is simpler than a conventional engine. If you're considering one, request the full MOT history to see what those advisories actually are; electric vehicles are still new enough that patterns aren't yet obvious, so understanding what this particular car needed matters more than the average.

We have limited data for the 2021 Volkswagen Id4 Max — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
