B (2020+, PSA CMP) · 2020–present
1.2 Turbo 100 · 100 hp · 1.2 Turbo 130 · 130 hp · Mokka-e (50 kWh) · 136 hp
Known problems
- Critical usually from 37,000 mi (60,000 km)
1.2 PureTech wet timing belt (belt-in-oil) degradation
Symptoms: belt material breaking down and shedding debris into the oil; can block the oil pickup/strainer or VVT solenoids, causing low oil pressure, rattling, warning lights and, in the worst case, sudden major engine damage
What to do: The most important check on this engine. Verify the wet timing belt has been serviced with the revised part on the shortened interval and that only the correct oil has been used; consider earlier belt replacement. Investigate any oil-pressure warning, rattle or metallic debris in the oil immediately. Stellantis extended warranty coverage and opened a compensation scheme for affected PureTech engines.
- Worth watching usually from 37,000 mi (60,000 km)
1.2 PureTech oil consumption and three-cylinder ancillary wear
Symptoms: elevated oil consumption between services, and reports of turbo, tensioner and timing-related wear on higher-mileage or poorly-maintained examples
What to do: Check oil level regularly between services and keep strictly to the specified oil and intervals. Oil starvation accelerates the belt-in-oil problem above, so treat oil consumption as a warning sign, not a nuisance.
- Good to know usually from 0 mi (0 km)
Mokka-e / infotainment and 12V-battery niggles
Symptoms: occasional infotainment freezes or reboots and 12V-battery drain/flat-battery reports on early cars
What to do: Largely addressed by software updates; ensure the car has the latest infotainment/BMS software. Have the 12V battery checked if it goes flat repeatedly.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change (1.2 PureTech) important | every 9,000 mi (15,000 km) or 12 months | Use only the exact Stellantis-specified low-ash oil and change on schedule (many owners shorten it). The wet timing belt runs in the oil, so oil condition directly affects belt life on the 1.2 PureTech. |
| EV service (Mokka-e): brake fluid, coolant, cabin filter, brake inspection | every 19,000 mi (30,000 km) or 24 months | No engine oil service. Regenerative braking means low pad wear but calipers still need periodic inspection; check high-voltage battery coolant. |
| Wet timing belt replacement (1.2 PureTech) critical | every 62,000 mi (100,000 km) or 120 months | The 1.2 PureTech uses a belt-in-oil design. Stellantis revised the belt and shortened the replacement interval; treat earlier replacement as prudent and confirm the belt service history on any used car. |
A / Mokka X (2012-2019, GM) · 2012–2019
1.4 Turbo 140 · 140 hp · 1.6 CDTi 136 · 136 hp
Known problems
- Worth watching usually from 25,000 mi (40,000 km)
1.6 CDTi diesel DPF / EGR clogging on short journeys
Symptoms: DPF warning light, frequent or failed regenerations, EGR-related running issues and oil dilution on cars used mainly for short urban trips
What to do: The 1.6 CDTi needs regular longer runs to complete DPF regeneration. Poorly suited to short-trip-only use; verify DPF/EGR health and let regenerations finish.
- Good to know usually from 62,000 mi (100,000 km)
1.4 Turbo (A14NET) general upkeep
Symptoms: reports of timing-chain/tensioner and turbo/carbon-related wear on neglected or high-mileage cars, and occasional coolant/water-pump issues
What to do: Keep to oil-change intervals with the correct oil and address any timing-chain rattle or coolant loss early. Generally durable when serviced.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | Shorter intervals are sensible for the turbo petrol and for short-trip diesel use. |
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.
