Honda R18Z engine: known problems

The CVT is reliable when serviced on schedule with genuine Honda CVT fluid, but neglected units develop torque-converter shudder, juddering on light throttle, slipping and in the worst cases complete failure - owners have reported gearbox replacements around 90,000km costing several thousand dollars. The unit is very sensitive to the correct fluid and regular changes.

The CVT can develop shudder or hesitation on light throttle take-off, usually traced to degraded CVT fluid or torque-converter lock-up behaviour.

Pre-facelift (2015-2018) cars use Honda's much-criticised capacitive touchscreen with no physical volume control, laggy software and no Apple CarPlay/Android Auto (added at the 2019 facelift). Units can freeze, reboot, lose audio or fail the touch layer entirely.

Owners report electronic parking brake warnings and occasional failure to release or engage, often traced to sensor faults, low battery voltage in cold weather or a failing EPB actuator. Some 2016-2019 cars were subject to brake-related service campaigns.

Honda's variable timing control (VTC) actuator can rattle for a second or two on a cold start (a 'marbles in a tin' noise) as the locking pin fails to hold with low oil pressure. Largely a noise nuisance, but a neglected one can wear chain guides.

Rear/lower engine mounts soften with age, allowing extra vibration and a clunk on take-off.

Documented paint defects including peeling or flaking clear coat (notably on the roof) and a rough or bubbly finish on plastic window trim on some examples in the Australian climate.
