Verdict for the versions it uses
e-CMP 50 kWh, 136 hp (2019-2024)2019–2024 · 136 hp
With cautionCars built before 2022 may have two outstanding campaigns: one for a high-voltage power cut (2022) and one for battery control calibration (2023). Check with the VIN that they were carried out. The battery, on the other hand, holds up well: Aviloo measures a median of 94% at 50,000 km and 90.7% at 150,000 km in the e-208 and Corsa-e.[3][4][5]
e-CMP second generation 54 kWh, 156 hp (2022-)since 2022 · 156 hp · eMotors M3
With cautionThis generation is still recent: there are few owner reports and only one campaign of its own (Astra Electric, 2023), but it also inherits the charger and power electronics design of the first. Check for campaigns and remaining warranty.[6][7][8]
Faults that affect the C4 III
Only those that affect the versions and years that this car used. The Stellantis e-CMP (e-208, Corsa-e, ë-C4…) has 5 documented faults in total.
- High severityFrequency: OccasionalTraction batteryTraction battery control calibration: motor cut-out from faulty readings (2022)A faulty software calibration of the battery control unit could misread the cell voltage or temperature and trigger an emergency motor cut-out. It affected Stellantis and Toyota electric cars built in 2022.
- Critical severityFrequency: RareElectronicsAstra Electric: communication fault between control units that can make the car move backwards (2023)In 2023 Opel recalled 1,466 Astra L Electrics because a communication fault between the engine control unit and the body control unit misread the immobiliser data, and the car could move in reverse when pulling away on a slope.
- Medium severityFrequency: OccasionalChargingOn-board charger and charging port: AC charging refused or interruptedOwners of the e-208, e-2008, Corsa-e, ë-C4 and 600e mainly cite faults with the on-board charger, the cable lock or the charging port, which stop AC charging even when the battery is healthy.
- Medium severityFrequency: OccasionalElectronicsFaulty air-conditioning compressor that can cut the drivetrain (2023)In 2023 the KBA published a campaign for Opel, Peugeot, Citroën and DS electric cars over a faulty air-conditioning compressor that can cause the drivetrain to disconnect. It is fixed with a software update.

Faults of the Citroën C4 III outside the engine
Suspension, brakes, electronics and the rest of the car: they occur with any engine.
- Critical severityFrequency: OccasionalElectrical systemFire risk from the small gap between the particulate filter and the 48 V starter-generator (mild-hybrid version)In the 48 V mild-hybrid versions of the C4 III (1.2 PureTech 136 hp with e-DCS6 gearbox) built between October 2023 and January 2026, the gap between the petrol particulate filter pipe and the 48 V starter-generator may be less than 10 mm, which poses a fire risk in the engine bay.
- Critical severityFrequency: OccasionalSuspensionCracks or fractures in the rear axle (built January-February 2023)Citroën recalled C4 III cars built between 26 January and 24 February 2023 because the rear axle may not meet specifications and may show cracks or fractures.
- Critical severityFrequency: OccasionalBrakesInternal brake fluid leak from the EBS valve block (built May-June 2024)In C4 III cars built between 29 May and 5 June 2024, the aluminium of the EBS valve block may not have fused completely around the valves, which causes internal brake fluid leaks and may lead to loss of ABS and stability control.
- Low severityFrequency: CommonElectronics and infotainmentFreezes, restarts and black screen on the multimedia systemSeveral C4 III owners report freezes, spontaneous restarts and black screens on the multimedia system, with loss of CarPlay, Android Auto or GPS navigation while driving.
