4th gen (GN) · 2021–present
2.4 PHEV · 248 hp · 2.5 MIVEC · 181 hp
Known problems
- Worth watching usually from 50,000 mi (80,000 km)
Direct-injection carbon buildup (PR25DD)
Symptoms: gradually rougher idle, misfires or reduced economy from deposits on the intake valves, and EGR/intake fouling typical of a direct-injected engine
What to do: Use quality fuel, keep to oil intervals, and have the intake valves cleaned (walnut blasting) if idle and economy deteriorate. Regular longer drives help keep deposits down.
- Worth watching usually from 62,000 mi (100,000 km)
Xtronic CVT durability and control software
Symptoms: the petrol car uses only a CVT; watch for overheating or juddering in heavy traffic, and note a software fault that could momentarily reduce the ratio at speed and stall the engine
What to do: Shorten CVT-fluid intervals (~45,000 km), avoid overheating the box in traffic or towing, and make sure any CVT-control-unit software recall has been carried out at a dealer.
- Good to know
Start-stop and infotainment glitches
Symptoms: occasional stop-start hesitation and minor infotainment/electronic quirks on early cars
What to do: Keep software up to date; most reports are usability-level rather than a mechanical fault.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | the 2.5 shares Nissan's PR25DD — ~10,000 km wise; halve for short-trip/severe use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 19,000 mi (30,000 km) | — |
| CVT fluid important | every 28,000 mi (45,000 km) | the petrol car uses the Nissan/Jatco Xtronic CVT — service earlier than the long factory interval; the PHEV has no CVT |
| Spark plugs | every 37,000 mi (60,000 km) | petrol |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | chain-driven — investigate any cold-start rattle |
3rd gen (GF/GG) · 2012–2021
2.0 MIVEC · 146 hp · 2.0 PHEV · 203 hp · 2.4 MIVEC · 167 hp
Known problems
- Worth watching usually from 50,000 mi (80,000 km)
Underbody and rear-subframe corrosion
Symptoms: rust on the rear subframe and its mounts, rear wheel arches, lower doors and sills, and around the fuel-filler pipe where dirt collects — a concern in salted-road climates
What to do: Wash the underbody through winter and apply anti-corrosion treatment; on a used car inspect the rear subframe and its mounting points on a lift, since heavy corrosion there is a structural, not cosmetic, problem.
- Worth watching usually 75,000–112,000 mi (120,000–180,000 km)
Jatco CVT wear and overheating
Symptoms: shudder or high-pitched whine, delayed or jerky engagement, and overheating in stop-and-go traffic or when towing; failures cluster at higher mileage, especially on the post-2015 JF016e box
What to do: Change the CVT fluid (and filter) well ahead of the maker's interval — roughly every 45,000 km — keep the cooler working, and avoid prolonged overheating in traffic or heavy towing. Have any shudder, whine or slip inspected early, before the belt and cones are damaged.
- Worth watching usually from 75,000 mi (120,000 km)
Timing-chain stretch (4B11 / 4B12)
Symptoms: rattle in the first seconds after a cold start; on a badly stretched chain, rough idle and a chain/timing fault warning
What to do: Keep oil fresh and at the correct level — chain stretch on these engines is driven by neglected oil and carbon. If you hear a cold-start rattle, have the chain, tensioner and guides inspected rather than ignoring it.
- Good to know
Infotainment and electronics quirks
Symptoms: laggy head unit, occasional Bluetooth or Apple CarPlay dropouts and screen glitches
What to do: Keep the head-unit software updated; most complaints are usability rather than a hardware fault, and a restart clears many temporary glitches.
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 to ~7,500 km for short-trip/city or severe use — fresh oil directly protects the timing chain |
| Air filter | every 19,000 mi (30,000 km) | — |
| CVT fluid (Jatco) important | every 28,000 mi (45,000 km) | gas 2.0/2.4 use a Jatco CVT — service earlier than the maker's long interval, especially if you tow or drive in heavy traffic; the PHEV has no CVT |
| Spark plugs | every 37,000 mi (60,000 km) | iridium; petrol engines |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | chain-driven — no scheduled replacement, but investigate any cold-start rattle |
Manufacturer-declared fuel economy
| Engine | City | Highway | Combined | Cycle |
|---|---|---|---|---|
| 2.5 MIVEC 4th gen (GN) · 2021–present | 24 mpg (9.8 L/100 km) | 31 mpg (7.7 L/100 km) | 26 mpg (8.9 L/100 km) | EPA |
| 2.0 MIVEC 3rd gen (GF/GG) · 2012–2021 | 24 mpg (10 L/100 km) | 29 mpg (8.1 L/100 km) | 26 mpg (9 L/100 km) | EPA |
| 2.4 MIVEC 3rd gen (GF/GG) · 2012–2021 | 23 mpg (10.2 L/100 km) | 29 mpg (8.1 L/100 km) | 25 mpg (9.4 L/100 km) | EPA |
Lab-cycle figures, each shown with the cycle it was measured under — the same car under WLTP, NEDC, EPA or JC08 can differ by up to 20%. Real-world consumption typically runs 15–30% above the declared number, and that gap is normal, not a fault.
