Toyota Highlander Hev MOT pass rate & common failures
The Toyota Highlander Hev appears in 1,197 MOT tests spanning model years 2021–2023, and 92.2% of them passed. All cars of a similar age fail at 8.6%, so the Highlander Hev sits squarely on the average. Its most common failure areas are visibility, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — visibility (4.6%) and lighting & signalling (4.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, wipers and tread depth — headlamp aim alone was recorded 72 times.
Condition tracks the odometer closely. Failures run at 6.3% in the 0-30k band and 16.3% in the 60-90k band, a 10.0-point spread — more than double.
Tyres is the most common advisory, noted on 22.1% of tests — work that passed today but is likely due soon.

What to check before buying a Toyota Highlander Hev
- Visibility (4.6% 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.
- Lighting & signalling (4.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.2% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
