2015 Toyota Noah — MOT failures & pass rate
The 2015 Toyota Noah passed 86.1% of its 417 recorded MOT tests. All cars of a similar age fail 17.3% of the time, so this is 3.3pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and visibility.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 11.0% of tests against 5.5% for the next-worst category.
At component level the recurring items are headlamp aim, rear fog lamp and headlamp — headlamp aim alone was recorded 14 times.
Condition tracks the odometer closely. Failures run at 5.3% in the 30-60k band and 25.0% in the 150k+ band, a 19.7-point spread — more than double.
Suspension is the most common advisory, noted on 15.8% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 25.0% in 2021 to 9.4% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2015 Noah
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.0% of tests. Start there.
- Lighting & signalling (11.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.5% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Visibility (4.1% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
