On the 2020-2024 Opel Mokka Electric, mokka-e (and closely related Corsa-e, Peugeot e-208, DS 3 Crossback E-Tense — all CMP/eCMP platform) drains the 12V AGM auxiliary battery during long parking spells, leaving the car unable to wake or charge. Owners report drain as fast as 3-5 days of inactivity. The MyOpel smartphone app polling the car wakes systems and accelerates drain. Stellantis acknowledged the issue and pushed multiple software updates between 2021-2024 — Opel recalled ~13,507 Corsa/Combo/Mokka in Germany alone for the traction battery control software.
Common Symptoms
dead 12V
car will not wake
will not start HV system
will not begin charging
How to Fix
Update vehicle software to latest (dealer can check; some VINs covered by recall). Use a 12V battery maintainer for parked stretches over 1 week. Disable MyOpel remote polling if parking long-term. AGM 12V replacement needs coding — DIY is risky; dealer cost ~€290 (€150-€250 battery + €50-€100 fit/code).

On the 2013-2020 Opel Mokka, combustion-engine Mokka/Mokka X owners frequently report the Start-Stop system ceasing to function alongside a flat or weak 12V battery, sometimes after the car stands for a week or two. The AGM/EFB battery and its state-of-charge management are central: when voltage dips below roughly 11.6V the ECU disables Start-Stop and can lose learned parameters. Some cases are simple battery wear or a marginal alternator, but persistent parasitic drains (modules not sleeping) have left some cars repeatedly going flat even after battery replacement.
Common Symptoms
Start-Stop not working / warning message
Flat battery after standing
Slow/no crank
Repeated battery replacement without fixing drain
Electrical glitches
How to Fix
Test the battery and alternator first and fit the correct AGM/EFB battery with proper coding/registration; if drain persists, perform a parasitic-draw test to find the module/circuit staying awake and repair it. Ensure software is up to date.
