Stellantis e-CMP: motor síncrono de 100 and 115 kW and baterías de 50 a 75 kWhHigh-voltage battery (hybrids and EVs)
Traction battery control calibration: motor cut-out from faulty readings (2022) on the Stellantis e-CMP (e-208, Corsa-e, ë-C4…)
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.[1]
Why this rating?
High severity: Risk of a serious engine, turbo or gearbox failure.
Frequency occasional: This was a preventive recall, fixed with a software update of about 30 minutes. Opel reported only isolated cases, at low speed and with no damage, so it is rated ‘occasional’ despite the 21,349 Peugeots affected worldwide.[1]
Symptoms
- The car loses drive power while driving because the emergency system switches the motor off.[1]Less power: other faults that cause it · Monitor
Why it happens
An error in the software calibration of the traction battery control unit can misread the cell voltage or temperature, and the emergency system disconnects the motor to protect the battery.[1]
If it is not repaired: Loss of drive power which, according to the source, may increase the risk of an accident; Opel knew only of isolated cases at low speed.[1]
Affected cars and years
Citroën e-Berlingo and e-C4, DS 3 Crossback, Opel Corsa, Combo and Mokka, Peugeot e-208, e-308, e-2008 and e-Partner built in 2022, and Toyota Proace City Electric (6 September to 30 November 2022).[1]

How much it costs to repair
Includes: Software update of the battery control unit with a standard diagnostic tool (up to 30 minutes).[1]
Free under the recall.
Prices in Spain, including VAT. A workshop hour costs on average €38–66 at independent garages and €77–134 at dealerships in Spain, depending on the region and the brand. How we calculate costs
How to check for it before buying a used car
- Check with the VIN that the 2022 campaign (codes KEG on Opel, MDY on Peugeot, JPD on Citroën and DS, CI23-001 on Toyota) was carried out.[1]
How to prevent it
- Have the software update done at an official dealer; it requires no parts.[1]

What owners say
Frequently asked questions
Does my 2022 electric car need this update?
The affected models are 2022 builds; the VIN confirms it on the brand’s website or at an official dealer.[1]
How much does the update cost?
Nothing: it is a recall, and the work takes up to 30 minutes.[1]
Is the battery damaged if the motor cuts out?
The cut-out is made by the emergency system precisely to avoid damage to the battery; the source does not mention damage to the cells.[1]

Other Stellantis e-CMP (e-208, Corsa-e, ë-C4…) faults
- High severityFrequency: OccasionalPower electronicsLoss of traction from a high-voltage system cut-out (‘electric traction fault’ warning)In 2022 Stellantis recalled the 2019-2020 e-208, e-2008, DS 3 E-Tense and Corsa-e because a high-voltage circuit safety system, set too sensitively, could cut the power and leave the car without traction.
- 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.

- High severityFrequency: CommonFord Mustang Mach-EHigh-voltage battery contactors overheating: loss of powerYes: the main contactors of the Mach-E's high-voltage battery can overheat with repeated rapid charging and hard acceleration, and the car may lose traction or fail to start. The 2022 software update was not enough, and in December 2023 Ford moved to replace the contactor box.
- Critical severityFrequency: OccasionalBMW eDrive de 5.ª generación (iX3, i4, iX)Cells with a damaged cathode in the high-voltage battery (fire risk)Yes: in September 2022 Safety Gate listed a BMW recall for a manufacturing defect in the high-voltage battery of the iX, i4 and i7 built from 5 July 2021 to 8 July 2022. A supplier may have damaged a cathode plate and a fragment may have entered a cell; the defective modules are replaced, and BMW asked owners not to charge or drive the car until then.
- Critical severityFrequency: OccasionalBMW i3 / Mini Cooper SEDefective cells in the high-voltage battery of the i3 from 2018 to 2021Yes: in October 2022 BMW launched a recall of the i3 built from 26/10/2018 to 31/08/2021 because a production defect in the winding of the cells' internal foils can overheat the modules and cause a fire. The defective module is replaced.
- Critical severityFrequency: CommonCitroën C5 AircrossOverheating and water ingress in the high-voltage battery (Hybrid versions)The plug-in Hybrid versions of the C5 Aircross built between January 2020 and the end of 2022 have been the subject of several successive manufacturer campaigns over a risk of the high-voltage battery overheating and, in another related campaign, over possible water ingress into its casing.
- Critical severityFrequency: CommonFord Kuga IIIFire risk in the plug-in hybrid high-voltage battery (recall 25SC4)The cells of the Kuga PHEV's high-voltage battery (made by Samsung SDI) can suffer an internal short circuit because of a damaged separator, with a risk of power loss and fire; Ford has recalled units built between August 2019 and November 2023.
- Critical severityFrequency: CommonOpel Grandland IRisk of overheating and fire of the high-voltage battery on plug-in hybrid versions (2019-2022)The plug-in hybrid versions of the Grandland X built between 2019 and 2022 have been the subject of several successive campaigns - first a software update and then physical replacement - over the risk of overheating and fire of the high-voltage battery.
