The Aygo is a quirky city car packed with personality. Mechanically, it's almost identical to the Peugeot 108 and Citroen C1, but it’s cheaper to buy and run. If you ask us, it’s also better looking.
This guide examines known issues with the Toyota Aygo, providing owners and potential buyers with insights into specific faults and their average repair costs.
In a nutshell: The Toyota Aygo is one of the more reliable city cars you can buy, especially in second-generation form. Common problems include clutch wear, water leaks, water pump failure on older cars, and jerky automated-manual gearboxes, but most issues are relatively minor and cheap to put right.

| R/2014/172 | 28.01.15 | The front shock absorber rod may have an internal fault which could cause it to break. This could have an adverse affect on the front suspension and the driver's ability to control the vehicle. |
| R/2014/020 | 03.03.14 | On subject vehicles there is a possibility that a wld on the rear axle may not be sufficient. In the worst case scenarios this could cause a break in connection between rear axle and the body. This could cause difficulty in controlling the vehicle. |
| R/2010/010 | 06.02.10 | It has been identified that on affected vehicles condensation resulting from cold-weather use of the heater or other causes may form on the worn surface of a component within the throttle pedal assembly known as the friction device. If this occurs there is a possibility that in the worst case the accelerator pedal may return slowly or does not return to the engine idle position. |
Toyota Aygo 2005-2014 problems
The first-generation Aygo is generally a dependable little car, but it does have a few well-known weak spots. The main ones to look out for are clutch wear, water pump failure and water leaks into the cabin or boot.
1. Clutch problems
Clutch trouble is one of the best-known issues on older Aygos. Common signs include a high biting point, squeaking when you lift the clutch pedal and difficulty changing gear. Earlier cars seem more prone to it; later models were fitted with a stronger clutch.
What repair is needed for clutch failure, and how much does it cost?
The usual fix is a clutch replacement. On some cars, that’s all that’s needed, but if the clutch has been slipping for a while, the garage may also want to inspect related parts. The average price of a clutch replacement on FixMyCar is £690.48.
2. Water pump failure
Water pump failure is another known issue on early Aygos. If the pump is starting to fail, you might notice coolant loss, overheating or a whining noise from the engine bay. It’s not a fault to ignore, because if the engine overheats, the repair bill can rise quickly.
What repair is needed for water pump failure, and how much does it cost?
The faulty water pump needs to be replaced, and the cooling system should be checked at the same time to make sure there are no other leaks. If the car has been driven while overheating, extra repairs may be needed.
3. Water leaks
Water leaks are another common Aygo complaint. Water can get into the boot because of poorly fitted weather seals, and some cars also suffer damp in the front footwell because of a faulty vent. If you’re viewing one, check the carpets and boot floor carefully for moisture.
What repair is needed for water leaks, and how much does it cost?
The fix depends on where the leak is coming from. A garage may need to replace seals, reseal the affected area or repair the faulty vent. Water leaks are usually cheaper to sort if you catch them early, before they cause mould, smells or electrical issues. The average price of a leak repair on FixMyCar is £101.59.
4. Jerky automated manual gearbox
If you’re looking at an Aygo with the so-called automatic gearbox, it’s worth knowing that it’s actually an automated manual. These cars can feel jerky or hesitant at low speeds, which is a known characteristic rather than always being a sign of a major fault. It’s still worth checking carefully on a test drive to make sure the gear changes feel acceptable to you.
What repair is needed for a jerky automated manual gearbox, and how much does it cost?
Sometimes there isn’t a fault as such; the gearbox may just be behaving as these systems often do. But if the changes feel especially poor, the car may need a diagnostic check, and the clutch and gearbox actuators may also need inspection.
5. Oxygen sensor faults
The oxygen sensor can cause problems on some Aygos. If it fails, you may see the engine warning light come on, and the car might run less efficiently than usual.
What repair is needed for oxygen sensor faults, and how much does it cost?
The first step is a diagnostic test to confirm the sensor is actually at fault, because an engine warning light can mean several different things. If the oxygen sensor has failed, it will need to be replaced.
Toyota Aygo 2014-2021 problems
1. Clutch wear
Clutch problems are less common on this generation than on the older Aygo, but they haven’t disappeared completely. On a test drive, check for a high biting point, slipping, juddering or gears that feel awkward to engage, because these can all point to a worn clutch.
What repair is needed for clutch wear, and how much does it cost?
The usual fix is a clutch replacement. If the clutch has been slipping for a while, the garage may also want to inspect related parts for wear. Replacing a clutch costs an average of £690.48 on FixMyCar.
2. Exhaust problems
Some owners have reported exhaust issues on this Aygo, usually noticed as a growly or unusually loud sound from the tailpipe. That doesn’t always mean a major failure, but it’s worth checking because an exhaust leak or worn component can make the car noisier and less pleasant to drive.
What repair is needed for exhaust problems, and how much does it cost?
A garage will need to inspect the exhaust system to find the source of the noise. The fix could be as simple as replacing a worn section or seal, but the price depends on which part has failed. The average price of an exhaust repair on FixMyCar is £151.52.
3. Worn brakes
Some Mk2 Aygos have been reported to suffer from squealing or juddering brakes. That doesn’t always mean there’s a major fault, but it can point to worn pads, uneven wear or brake parts that need attention sooner than expected.
What repair is needed for worn brakes, and how much does it cost?
The usual fix is to inspect the brakes and replace worn parts if needed. That may mean new brake pads (average price: £257.48), or pads and discs together (£574.72) if there’s more significant wear.
Toyota Aygo years to avoid
There isn’t one standout Aygo year that’s best avoided across the board. Overall, the Aygo has a strong reputation for reliability, especially the 2014-2021 generation.
If you want to play it safe, these are the years worth treating with extra caution:
2005-2009 - these early first-generation cars are the ones most closely linked to clutch wear and water pump failure, so they’re the Aygo years we’d be most careful with.
2005-2014 automated-manual models - not every car will have problems, but the so-called automatic gearbox can feel jerky and hesitant, so it’s worth trying one properly before you buy.
Is the Toyota Aygo reliable?
The Toyota Aygo has a strong reputation for reliability, especially newer models. In What Car?’s latest reliability data, the 2014-2021 Aygo is described as a very reliable car with few reported faults, while the newer Aygo X has performed even better, achieving a perfect 100% reliability rating in one recent survey and 99.7% in a later update. That makes the Aygo one of the strongest small cars for dependability, even if older first-generation cars are a bit more prone to issues like clutch wear and water leaks.
