Hailed as one of the best cars for new drivers, the Toyota Yaris is safe, reliable and fun to drive. Not to mention it’s superbly economical, which in the current financial climate is the biggest compliment a car can receive. But how does it fare in terms of reliability?
This guide examines known issues with the Yaris, providing owners and potential buyers with insights into specific faults and their average repair costs.
In a nutshell: The Toyota Yaris is generally a dependable small car. Older cars (2006-2011) are most prone to MMT auto gearbox quirks, clutch judder, and the occasional engine warning light, while 2011-2020 models can suffer minor electrical glitches, DPF blockages on diesels, and suspension noises. On 2020-present hybrids, the most talked-about niggle is the 12V battery going flat if the car isn’t used regularly. Overall, reliability remains a Yaris strong point.
What’s wrong with the Toyota Yaris?
Drivers are searching online for information about the following problems.
Toyota Yaris semi-automatic gearbox problem
Symptoms include no response from the vehicle when in gear, unusual noises when changing gear and shaking or grinding. A gearbox oil leak could be to blame, or the gear shift and clutch servos may simply have worn out.
Average auto gearbox repair price: £562.22
Toyota Yaris Cross battery problem
Some Yaris Cross owners - particularly of the hybrid variant - report that the 12 V auxiliary battery can drain unusually quickly when the car sits unused or on lots of short trips. This is often attributed to the charging characteristics of hybrid electrical systems rather than a mechanical fault.
Average hybrid car battery repair price: £470.76
Toyota Yaris engine problems
Some owners report a small number of engine-related issues worth being aware of. On 1.0-litre petrol versions, sluggish acceleration or hesitation at low revs is often linked to the engine’s limited power output, rather than a mechanical fault. No repair is usually needed unless poor running is caused by worn components such as spark plugs or a dirty throttle body, which are relatively inexpensive to fix.
On 1.4-litre diesel models, reduced power or warning lights can sometimes be traced back to turbocharger wear or diesel particulate filter (DPF) blockages, typically caused by frequent short journeys. Repairs may range from a DPF clean or sensor replacement to turbo repairs in more severe cases.
Hybrid models are generally well regarded mechanically, with no widely reported engine faults beyond routine maintenance-related issues.
Average spark plug replacement price: £163.96
Average DPF clean price: £207.06
Recent recalls

The inner belt (buckle portion) of each of the rear three seat belt assemblies is secured to the floor of the vehicle with an anchor plate. The anchor plate might have been manufactured with a sharp edge around the punched portion. In the event of a collision there is a possibility that the inner seat belt webbing could become cut and separate at the anchor plate. If this occurs the inner seat belt may not properly restrain the occupant which could increase the risk to injury. |
Toyota Yaris 2006-2011 problems
1. Erratic auto gearbox
Some Yaris models fitted with the automated MMT transmission can change gear erratically, particularly when downshifting at inappropriate times. This tends to show up most clearly on cooler starts or when the gearbox hasn’t fully warmed up.
What repair is needed for an erratic auto gearbox, and how much does it cost?
A diagnostic is usually needed first to confirm the problem. If the transmission unit itself is at fault, options include rebuilding or replacing the MMT control unit and mechanical components, which can cost several hundred to over a thousand pounds. Because this variant is known for quirks, many owners choose a manual gearbox version when buying used to avoid the issue entirely.
The average price of an automatic gearbox repair on FixMyCar is £562.22.
2. Juddering clutch
Some second-generation Yaris owners report that the clutch judders or slips when accelerating and changing gear, sometimes sooner than expected for the car’s mileage.
What repair is needed for a juddering clutch, and how much does it cost?
Clutch judder typically requires the clutch assembly to be replaced, including the disc, pressure plate, and often the flywheel. Labour is intensive as this involves removing the gearbox.
Replacing the clutch on a Yaris costs £633.26 on average.
3. Engine warning light
Older diesel Yaris models sometimes display an engine warning light, which can indicate misfires, glow plug wear, or particulate filter issues.
What repair is needed for the engine warning light, and how much does it cost?
When the check engine light comes on, the first thing to do is to run a diagnostic test to find out what the problem is. A mechanic will plug a machine into your car to read the error code.
A diagnostic test costs £59.84 on average for a Yaris.
4. Loose fan belt
Owners occasionally report squealing or chirping noises from the engine bay on start-up or when accelerating, commonly traced to loose or worn belts. Over the long term, belts and their tensioners age and stretch, reducing efficiency and sometimes leading to noise.
What repair is needed for a loose fan belt, and how much does it cost?
A technician will inspect the belt condition and tension. Often, belt replacement alone is sufficient, which is a relatively straightforward job at most garages and typically costs around £80-£120 though prices vary by location and belt type.
5. Worn water pump
Some long-term owners note that the water pump can begin to show wear on early Yaris models (a common mechanical wear item in small petrol engines), leading to coolant leaks or overheating if left unchecked.
What repair is needed for a worn water pump, and how much does it cost?
Water pump replacement is a standard service item once signs of wear or leakage appear. It costs £327.27 on average.
Toyota Yaris 2011-2020 problems
1. Electrical glitches
Some owners report intermittent dashboard warning lights or minor electrical issues, such as temporary sensor warnings or centre console display quirks, often without serious fault codes appearing in diagnostics. These are typically nuisance faults rather than indicators of imminent major failure, but they are among the most commonly reported minor problems for this generation.
What repair is needed for electrical glitches, and how much does it cost?
A diagnostic scan (average cost: £59.84) is the first step to check for stored fault codes and rule out underlying faults. If a specific sensor or connector is at fault, repairs can range from £60 to £200+, depending on the component and the labour required.
2. Blocked DPF
Diesel-engined Yaris cars in this period can go into limp mode or lose power if the diesel particulate filter becomes blocked, especially when the vehicle is used for short urban trips that don’t allow the filter to regenerate properly.
What repair is needed for a blocked DPF, and how much does it cost for a Toyota Yaris?
A simple DPF clean should resolve minor blockages, costing an average of £221.06 for a Yaris. In more stubborn cases, DPF replacement may be required, which pushes the average cost to £596.20.
3. Fuel injector seal deterioration
Some later cars in this range have been reported to suffer from fuel injector seal leaks, which can cause fuel smells, drips under the vehicle, or increased fuel consumption. This isn’t a universal issue, but it does come up frequently enough in owner discussions.
What repair is needed for fuel injector seal deterioration, and how much does it cost?
The repair involves replacing the injector seals and sometimes cleaning the injectors. Parts and labour for this typically range from £150 to £350, depending on how many seals are affected and workshop rates. Leaks should be addressed promptly to avoid fuel wastage and potential fire risk.
4. Suspension noises
A number of owners report creaks, rattles or clunks from the suspension at low speeds or over bumps.
What repair is needed for suspension noises, and how much does it cost?
Suspension noise diagnosis may lead to replacement of bushes, shock absorbers or mountings. The average price of a Yaris suspension repair is £254.11.
Toyota Yaris 2020-present problems
1. Flat 12V battery
One of the most frequently mentioned issues for the hybrid 2020-present Yaris is that the 12-volt battery can drain if the car isn’t used regularly, resulting in a flat battery after only a few days or weeks of low use. This tends to occur more on vehicles used for short trips or parked for long periods without running.
What repair is needed for a flat 12V battery, and how much does it cost?
If a flat battery is diagnosed, it typically requires a full battery health check to confirm the condition and, sometimes, a replacement battery. Parts and fitting for a new 12 V battery usually cost £150-£300 at an independent garage, though prices vary by location and battery type.
2. Hybrid system warning
Occasionally, owners report that the car shows a hybrid system warning message or multiple dashboard warning lights, with various systems flagged.
What repair is needed for a hybrid system warning, and how much does it cost?
The first step is a full diagnostic scan (£59.84 on average) to read stored codes and isolate which system triggered the warning. Repairs can vary widely, from a simple sensor reset or connector fix to more involved repairs if a specific hybrid control module or sensor is at fault. Because hybrid systems are complex, parts and labour costs can vary from £100 to several hundred pounds depending on the exact fault.
3. Electrical glitches
Owners sometimes mention minor electrical or infotainment system quirks, such as screens freezing, Bluetooth dropping out, or sensors behaving oddly after exposure to dust or light moisture.
What repair is needed for electrical glitches, and how much does it cost?
A software update or system reset often resolves these simpler electronic glitches and can be done at a dealer or specialist for £50-£100. If a specific component (e.g., the head unit or a sensor) needs to be replaced, costs can range from £200 to £400+, depending on the part, but many issues can be resolved with diagnostics and software adjustments first.
Is the Toyota Yaris reliable?
Reliability has long been a strong point of the Yaris. In the 2025 What Car? Reliability Survey, the latest Yaris placed 20th out of 28 cars in the small car class, with a 92.5% score, which is still a solid result in a competitive category.
It also has a strong track record in earlier results. In What Car?’s 2023 rundown of the most reliable used cars, the Yaris finished seventh overall and first in the small car class, and Toyota ranked second in the most reliable used car brand category.
