Yaris Passes 75% — Lights and Springs Flag
Toyota's reliability reputation holds up to a point: the Yaris clears 75.45% of MOTs across 527,880 tests, but headlamp lens defects and fractured coil springs are the most common failure triggers. Owners of the 1.33 CVT have reported snapped offside front springs — one was caught under an extended Toyota warranty at 65,000 miles, but that safety net won't apply to used buyers. The 1.4 D-4D diesel adds EGR complications at higher mileage. Pre-purchase checks should cover front lamp condition, both springs, and clutch play on manual versions, particularly below 60,000 miles.

Owner reports · Honest John
What owners actually report.
Verbatim faults logged by owners on honestjohn.co.uk over recent years. We didn't summarise — these are the words people typed in.
What's good
Fairly big boot by class standards, tempting hybrid option, Toyota has an epic reliability record.
Where it falls short
The Toyota Yaris feels a little dated these days, with a bland interior, inconsistent equipment levels, lacklustre performance and mediocre driving experience.

R eport of two issues with 2012 Toyota Yaris 1.33 CVT now at 65k miles. The offside front coil spring snapped, happily replaced under an extended Toyota warranty. But also has keyless entry and go which is playing up. The central locking has been malfunctioning with symptoms that include unlocking some doors and not others (completely at random). When in the vehicle we can hear the central locking "clicking" for a brief period as if something is slipping. As yet dealer has been unable to replicate this so not yet fixed.

2015 Toyota Yaris 1.4 D-4D needed a forced DPF regeneration and oil change at 18,000 miles, costing £275.

Problem occurred despite almost all mileage on motorway on 800 mile road trips at 2,000rpm.

Buying or keeping a Yaris?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Yaris and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
