2019 Hyundai I800 — MOT failures & pass rate
Across 8,546 MOT tests, the 2019 Hyundai I800 recorded an 84.6% pass rate. Against all cars of a similar age (10.1% fail rate), the 2019 I800 comes out 5.2pp worse. Failures cluster in lighting & signalling, visibility and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 17.7% of all tests — 12.2 points clear of visibility, so it is the first thing to check.
At component level the recurring items are headlamp, headlamp aim and wipers — headlamp alone was recorded 990 times.
Mileage matters less than usual here: the 2019 I800 fails 13.1% of the time in the 0-30k band and 15.2% at 150k+, a spread of only 2.0 points.
Advisories point at the next bill rather than this one: tyres was flagged on 21.2% of tests without failing them.
The trend is worsening — 7.7% of tests failed in 2021 against 14.8% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 I800
On a 2019 I800, lighting & signalling is what the MOT record says goes wrong most — it appeared in 17.7% of tests. Check these areas before you commit.
- Lighting & signalling (17.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (5.5% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Brakes (4.5% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
