Is the Toyota Yaris 2015–2020 reliable?
The Toyota Yaris is the used car you buy when you want zero drama. It won't excite you, the interior feels dated against rivals, and it's not particularly spacious — but it will almost certainly still be running without significant expense when everything else at this price point has needed major work.
The 2015–2020 generation comes in two flavours: the 1.0 and 1.5-litre petrol Yaris, and the 1.5-litre hybrid. Both are genuinely reliable. The hybrid is slightly more complex but Toyota's hybrid system has 25 years of development behind it and real-world failure rates are low.
The main caveat: the Yaris is not exciting to drive and the infotainment system is well behind the class average. If reliability is your only priority, it's hard to beat. If you want a more engaging drive or a premium feel, look elsewhere.
Known faults — what to watch for
These are the issues that come up repeatedly in owner forums, Which? reliability surveys, and DVLA MOT data. Not every car will have them — but every buyer should ask about them.
Hybrid battery capacity degradation
The hybrid battery doesn't fail catastrophically — it gradually loses capacity over time and high mileage. On a 100,000-mile hybrid Yaris the battery may only hold 70-80% of original charge, reducing the EV assist and fuel economy benefits. A full hybrid battery replacement is expensive but rarely necessary below 150,000 miles on a well-maintained car. Check the hybrid health display if buying a high-mileage example.
Medium risk on high mileageInfotainment and touchscreen faults
Toyota's infotainment systems from this era are behind competitors in both functionality and reliability. Screen unresponsiveness, Bluetooth pairing failures, and navigation errors are reported by owners. Not a deal-breaker but worth testing everything at the viewing. Aftermarket head units are available as a cheap fix if the system is faulty.
Medium annoyance riskAir conditioning compressor wear
The AC compressor on higher-mileage Yaris models can wear and eventually fail — a common issue across small city cars used predominantly in urban environments. Test the AC thoroughly at the viewing. A regas is cheap; a compressor replacement is not.
Low riskCVT transmission hum (hybrid)
The hybrid Yaris uses a CVT-style eCVT transmission rather than a conventional gearbox. A mild humming sound under acceleration is completely normal — many buyers mistake this for a fault. The transmission itself is extremely reliable. If the hum is very pronounced or accompanied by vibration, have it inspected.
Low risk — usually normalDoor seal and weather strip wear
On higher mileage examples the door weather strips can harden and crack, leading to wind noise at motorway speeds. This is a comfort issue rather than a mechanical one. Replacement strips are inexpensive — use it as a negotiating point on any car showing this wear.
Low riskDon't buy blind — check the car's full history first
Finance owing, previous write-offs, and clocked mileage won't show up on a visual inspection. Our report surfaces all of it instantly.

We analyse real DVLA MOT records across thousands of UK-registered examples from this generation. The data below reflects actual test outcomes — not manufacturer claims.
| Failure item | How common | What it means |
|---|---|---|
| Tyre wear | City car tyres wear faster with frequent low-speed manoeuvring. Budget £70–£120 per tyre. | |
| Brake pad wear | Hybrid models use regenerative braking so physical brake pads last longer — but check anyway. | |
| Rear light seal | Water ingress into rear light clusters is a common advisory. Cosmetic but worth noting. | |
| AC system | Compressor wear on older high-mileage examples. Test before purchase. | |
| Wiper blades | Often neglected. Check both front and rear. |
Pro tip: Toyota Yaris hybrid models often have very high mileage because owners rack up miles confidently. High mileage on a Yaris is less concerning than on most other cars — check the service history rather than dismissing it based on the odometer. PlateSure's full check pulls every MOT result, mileage reading, and advisory — instantly, for £9.99.
If the Yaris feels too basic, the Honda Jazz offers more interior space and similar reliability. For a step up in driving engagement, the Ford Fiesta is more fun but carries more mechanical risk.
What should you pay?
The Yaris holds its value unusually well given its reliability reputation. Don't expect significant discounts — but don't overpay for high mileage hybrid examples.
What to check at the viewing
- Hybrid or petrol? Both are reliable — hybrid suits urban use best.
- On hybrid models, check the hybrid health display for battery capacity indication.
- Full Toyota service history — Yaris with gaps in the record should be avoided.
- Test the AC thoroughly — compressor wear is the most common mechanical issue.
- Test the infotainment system fully — screen, Bluetooth, navigation.
- Check door seals on higher mileage examples — hardened seals cause wind noise.
- Listen for any unusual noise from the eCVT on hybrid models during the test drive.
- Check all four tyres for condition and age.
The most reliable used car in its class — without question
If reliability is your primary criterion the Toyota Yaris 2015–2020 is the answer. It's not exciting, the infotainment is dated, and it's not cheap relative to comparable city cars — but it will run and run with minimal drama. The hybrid system is mature and well-proven. The petrol version is even simpler. Buy one with full service history and reasonable mileage and you'll likely have years of trouble-free ownership. Run a full check before buying — Yaris models are popular with older buyers and occasionally have hidden finance outstanding.
Frequently asked questions
Is the Toyota Yaris hybrid reliable?
Yes — Toyota's hybrid system is one of the most proven in the industry with over 25 years of development. Battery degradation is gradual and rarely requires replacement before 150,000 miles. The hybrid Yaris is one of the most reliable used cars you can buy at this price point.
How long does a Toyota Yaris hybrid battery last?
Toyota claims hybrid batteries are designed to last the life of the car. In practice most batteries are still functioning well above 150,000 miles. Capacity gradually reduces with age and mileage but catastrophic failure before 200,000 miles is rare on well-maintained cars.
Is the Toyota Yaris good for motorway driving?
It's adequate but not its natural habitat. The 1.5-litre engines are comfortable at motorway speeds but feel stretched. The hybrid is more comfortable on A-roads and urban routes where the regenerative braking and EV assist provide the most benefit.
