Known problems
- Worth watching
12V battery drain and hybrid battery care
Symptoms: occasional 12V battery drain leading to no-start or electrical quirks; the hybrid/PHEV high-voltage battery needs normal ageing care
What to do: The most-cited niggle on this generation is 12V battery drain — keep the 12V battery healthy and, if the car sits for long spells, watch for a flat battery. Follow the hybrid-system service records and, on the PHEV, use the charging routine the handbook recommends.
- Good to know
Infotainment glitches and sensor niggles
Symptoms: occasional multimedia glitches, connectivity drops and driver-assist sensor niggles
What to do: Minor and typically fixed by a dealer software update. Keep the multimedia and vehicle software current and log anything persistent while under warranty.
- Good to know
Occasional CVT hesitation
Symptoms: the odd jerky or hesitant response from the Direct-Shift CVT in some conditions
What to do: This is generally a driveability characteristic rather than a fault. Keep the CVT fluid serviced and have any consistent shudder or slip checked, but don't over-read an occasional hesitation.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | halve under severe, city or short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | — |
| CVT / e-CVT fluid important | every 37,000 mi (60,000 km) | 2.0 uses a Direct-Shift CVT, the hybrids an e-CVT |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | — |

Known problems
- Worth watching usually from 50,000 mi (80,000 km)
2.0 turbo (8AR-FTS) cold-start noise and water pump
Symptoms: rattly or noisy running when cold that fades as the engine warms; some cars need a water-pump replacement, and the direct-injection turbo can be costly to service
What to do: On the turbo, keep to clean oil on a shorter interval — the oiling system is fussy — and treat a cold-start rattle that lingers as worth investigating. Have the electric water pump checked at service. The very early turbochargers (around 2015-2016) were improved under warranty, so later cars are the safer buy.
- Good to know
Infotainment and electronic glitches
Symptoms: occasional multimedia freezes or glitches, sensor niggles and, on some cars, sunroof noise after years of use
What to do: These are minor and usually resolved by a software update or normal maintenance. Keep the multimedia software current and don't read a one-off screen glitch as a serious fault.
- Good to know usually from 56,000 mi (90,000 km)
Steering and suspension ball-joint knock
Symptoms: knocking or clunking through turns and over bumps as steering and suspension ball joints and bushings wear
What to do: A knock felt while turning usually points to a worn steering or suspension ball joint or bushing. Have them inspected at service and renew as needed; it is normal wear rather than a design defect on this generation.
- Good to know usually from 93,000 mi (150,000 km)
Hybrid 12V and HV battery ageing (2.5 hybrid)
Symptoms: a weak 12V battery causes no-starts and electrical quirks; the HV battery slowly loses capacity and range can dip in extreme heat
What to do: On the hybrid, keep the 12V battery healthy — it causes many odd faults when tired — and budget for eventual HV-battery service on very high-mileage cars. Park in shade in hot climates to ease the pack.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | halve under severe, city or short-trip use; the 2.0 turbo especially benefits from clean oil |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | — |
| Automatic / CVT / e-CVT fluid important | every 37,000 mi (60,000 km) | NA 2.0 uses a CVT, the turbo an automatic, the hybrid an e-CVT |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | shorten to roughly 60k km on the 2.0 turbo |
| Brake fluid important | every 36 months | — |
| Timing chain | — | all engines are chain-driven — no scheduled belt replacement |
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.
