  since 2022 · 184 hp

  With caution

  No serious widespread faults documented; in France the high-pressure fuel pump campaign includes Civic hybrids built between April 2022 and September 2024, so check the VIN.^[2][4]

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.

1. 1High severityFrequency: OccasionalFuelCracked high-pressure fuel pump (Honda campaign 6YP)Honda recalled around 1.38 million Civic, CR-V and ZR-V cars built between 2021 and 2024 in Europe because the high-pressure fuel pump could crack, causing a fuel leak and a risk of fire. In France it was later extended to 4,740 hybrids.
2. 2Low severityFrequency: OccasionalElectronics12 V battery going flat and hybrid system failing to startIf the car stands unused for a long time, the 12 V auxiliary battery can go flat and the hybrid system does not activate ("Ready" does not appear) even though the traction battery is charged. It is fixed by charging or replacing the battery.Repair (garage): €120–€250
