The NiMH high-voltage battery of the IMA system degrades over time due to cell imbalance. From around 130,000–150,000 km, capacity drops significantly. A new Honda battery costs €3,300–€5,500.

Symptoms: IMA warning light on, reduced hybrid output, engine runs on petrol alone more frequently

When the IMA high-voltage battery fails, the DC-DC converter can no longer charge the 12V battery. The vehicle becomes unable to start. Converter replacement costs around €2,150.

Symptoms: 12V battery drains while driving, vehicle won't start, IMA warning light on

Active IMA fault codes cause an MOT failure as the OBD readiness monitors cannot be fully set.

Symptoms: IMA warning light permanently active, OBD readiness not set, MOT/vehicle inspection fails

Multiple recall campaigns for driver and passenger airbags (2016 and 2019) due to faulty Takata gas generators that can propel metal fragments when deployed. Check with a dealer without delay.

On vehicles with i-Shift gearbox, a software fault in the control unit can cause the engine to stall at traffic lights or the vehicle to roll backwards. Affected: May 2008 to December 2011.

The air conditioning is a Honda-typical weak point: the relay (Omron brand) fails prematurely; alternatively the magnetic clutch or compressor fails. Mitsuba brand replacement relay recommended.

The rear brakes seize on city vehicles with low mileage. Regular cleaning and greasing of the brake callipers is required to prevent seizure.

Models from 2009 onwards show rust starting in the rear left wheel arch in the area of the fuel filler cap. The boot can also take in water through leaks, which promotes corrosion.

The multi-disc wet clutch (start clutch) in the CVT gets contaminated by spent additives in the gearbox oil. An oil change helps temporarily; the revised start clutch assembly must be fitted for a permanent fix.
