2021 Hyundai Tucson SE Nav48v MHEV CRDI 2wd
CarHunch analysed 1,551 real MOT records for the 2021 Hyundai Tucson SE Nav48v MHEV CRDI 2wd. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Hyundai Tucson SE NAV hybrid diesel is slightly more reliable than average, with an 86.3% first-time pass rate against the UK average of 80%, and only 7.2% of vehicles have ever recorded a dangerous defect—a reassuringly low figure. The electric diesel variant (which makes up 91% of this cohort) achieves an 85.2% pass rate, while the smaller "Other" fuel group hits 98%, though that's based on only 123 vehicles.
These cars are running at typical mileage for their age, with a median of just under 32,000 miles, and they're encountering fewer failures than many rivals—averaging just 0.34 failures per test. The 1.9 advisories per vehicle suggest minor wear items are the main concern rather than structural problems. If you're considering one, prioritise a full pre-purchase inspection focusing on the hybrid electrical systems and battery health, as these specialist components fall outside typical MOT checks.
What to check before buying a 2021 Hyundai Tucson SE Nav48v MHEV CRDI 2wd
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
