1.0 Boosterjet · 111 hp · 1.2 Dualjet · 90 hp
Known problems
- Worth watching
Body corrosion in salted climates
Symptoms: surface rust around wheel arches, door/tailgate edges and underbody fixings on cars run through winter road salt
What to do: Rinse off winter salt, keep drains clear and treat any bubbling promptly; check the arches and underbody on a used example. Less prevalent than on the previous generation but still worth watching in salt regions.
- Good to know
Air-conditioning weakness
Symptoms: cooling that fades over time, usually a slow refrigerant leak from the front-mounted condenser
What to do: Pressure-test the A/C if it stops cooling well; a leaking condenser is the common cause and a simple fix. Repair the leak before regassing.
- Good to know usually from 37,000 mi (60,000 km)
1.0 Boosterjet carbon and mild-hybrid 12V battery
Symptoms: a gradually lumpier idle from direct-injection carbon on the turbo three-cylinder, and on SHVS mild-hybrid cars a 12V battery that tires under start-stop
What to do: Use good fuel and keep to the oil schedule to limit carbon on the Boosterjet; have the 12V battery load-tested if starts get sluggish or start-stop drops out. Both are minor on an otherwise very reliable car.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | ~10,000 km is wiser on the 1.0 Boosterjet turbo and under severe use; check the level between changes |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs | every 37,000 mi (60,000 km) | ~60,000 km on the 1.0 Boosterjet turbo; the naturally aspirated 1.2 Dualjet uses long-life iridium good to roughly 105,000 km |
| Brake fluid important | every 24 months | — |
| Timing chain | — | chain-driven — inspect for noise rather than scheduled replacement; keep oil fresh |
3rd gen (2010-2017) · 2010–2017
1.2 VVT · 94 hp
Known problems
- Worth watching
Body corrosion in salted climates
Symptoms: surface rust and bubbling around the rear wheel arches, tailgate/door edges and underbody, mainly on cars run through winter road salt
What to do: Wash off road salt in winter, keep drains clear and treat any bubbling early; inspect the underbody and arches when buying used. Cars in mild, salt-free climates are far less affected.
- Good to know
Air-conditioning weakness
Symptoms: gradually weaker cooling, most often a slow refrigerant loss from a leaking condenser or connections
What to do: Have the A/C system pressure-tested if cooling fades; a leaking condenser (exposed at the front of the car) is the usual culprit and is a straightforward repair. Regas only after the leak is fixed.
- Good to know usually from 81,000 mi (130,000 km)
Oil consumption on higher-mileage cars
Symptoms: the oil level drops between changes without an obvious leak, more noticeable past 120,000-130,000 km or if oil changes have been stretched
What to do: Check the oil level regularly and top up as needed; keep to the correct grade and don't overrun oil-change intervals. It is a monitoring item rather than a common failure on a generally durable engine.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | halve for severe/short-trip use; check the level between changes |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs | every 65,000 mi (105,000 km) | long-life iridium; sooner under severe use |
| Brake fluid important | every 24 months | — |
| Timing chain | — | the K-series is chain-driven — no scheduled belt; keep oil fresh and listen for cold-start rattle |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
