1.5L (LEA) i-VTEC + IMA Hybrid - Alpha/Top trim
Petrol-Electric Hybrid
While sitting at a complete stop in traffic or at a light, check for any shuttering during the Auto Stop-Start function. | Note: The IMA system relies on a smooth transition; intermittent vibrations might suggest the hybrid battery or the 12V auxiliary battery is beginning to lose its charge capacity.
Check this by shifting through all gears in a manual model or using the paddle shifters in the CVT while accelerating uphill. | Note: Clutch wear in the manual models or belt slippage in the CVT can occur; listen for any hesitation or engine revving that doesn't translate into immediate forward momentum.
When parked, check the underside for signs of oil seepage around the timing chain cover or transmission housing. | Note: With age, the rubber seals and gaskets in the 1.5L i-VTEC engine may naturally begin to show their years, so it is wise to keep an eye on your driveway for spots.
While driving on an uneven road, listen closely for rattles or clunks from the front suspension bushings and struts. | Note: New Zealand roads can be quite unforgiving on suspension components; it is common for the CR-Z to eventually require bushing replacements as the odometer climbs past the 100,000km mark.
Usually marks the time to inspect the IMA cooling fan for debris and ensure the cabin air filter has been changed to maintain system efficiency.
A sensible window to evaluate the health of the hybrid battery's state of charge consistency and potentially consider a spark plug refresh if not recently done.
At this point, one might consider a comprehensive inspection of the drivetrain mounts and the IMA system's main electrical contactors.
Ensure the IMA cooling fan intake (located on the side of the rear seat) is clear of dust or pet hair to prevent the battery from overheating.
Keep the 12V battery in top condition; the CR-Z’s electrical system can act quite strangely if the 12V battery voltage drops too low.
Regularly check your engine oil levels; although the LEA engine is robust, keeping the oil clean helps the VTEC solenoid function exactly as it should.
Use a reputable scan tool to occasionally check for hidden 'IMA' codes, which can sometimes appear long before the dashboard warning light illuminates.
Ensure your CVT fluid or manual gearbox oil has been changed at the manufacturer-recommended intervals to maintain smooth gear transitions.
Estimated repair costs if issues arise
If the IMA battery capacity degrades over time, you might eventually need to budget for a refurbished or replacement unit to restore full power assist.
If you notice slipping during spirited driving, you might consider setting aside funds for a clutch kit installation in the future.
To keep the CVT transmission shifting smoothly, it is good practice to include this service in your future budget every 40,000km.
