Opel Mokka
The PSA/Stellantis electric motor is fundamentally low-maintenance. However, sporadic drivetrain system faults are known that can lead to vehicle immobilisation. Software updates have resolved many cases.
Mokka-e with more power
The stronger variant feels barely different. Solid electric everyday use without surprises.
Engine Weaknesses 8
Sporadic 'electric drivetrain system fault' message blocks the vehicle: gearbox stays in park. Occurs from around 10,000 km, often self-resolving after 30 min. Software update brought improvement.
Symptoms: Display shows 'electric drivetrain system fault: stop vehicle'. Gearbox cannot be moved out of P
Isolated cases of gearbox oil loss through a crack in the gearbox casing. Complete gearbox replacement required. Long parts lead times.
Symptoms: Gearbox clunking, power loss, oil under the vehicle, gearbox fault message
The onboard charger (OBC) of the Corsa-e/Mokka-e fails frequently on early build years (2020–2021): AC charging via Type 2 no longer possible, DC rapid charging still works. Opel acknowledged the structural defect and offers special goodwill. OBC replacement approximately 4,000 €.
Symptoms: AC charging aborts immediately after plugging in, LED shows red, vehicle attempts to charge but connector unlocks immediately, DC charging still works.
Sporadic drivetrain fault messages on the Corsa-e/Mokka-e completely block driving. Typically a software reset by disconnecting the battery is sufficient, but a second start attempt after the warning can cause consequential damage.
Symptoms: Drivetrain fault warning light, vehicle won't move, no response to accelerator despite vehicle being switched on.
Electric Opel vans (Vivaro-e/Movano-e) can shut down the drivetrain at speed after DC rapid charging. Software fault — vehicle rolls to a stop, warning lights active.
Symptoms: Vehicle suddenly loses drive power at motorway speed after rapid charging; 'check drivetrain' message; fault usually self-clears after cooling down.
A faulty A/C compressor can deactivate the entire electric drivetrain. Recall carried out for model years 2021–2022. A/C compressor replacement approximately 800–1,500 €.
Symptoms: Drivetrain failure, A/C not working, warning message on display
Early Corsa-e vehicles (build year 2020) had a 12V battery with a production defect. The control unit didn't correctly enter bus sleep mode, leading to complete 12V battery discharge within 24 hours. Replacement under warranty/goodwill.
Symptoms: Vehicle won't start next morning, 12V voltage below 7.5V, all systems dead, no remote wake-up response.
Electric Opel commercial vehicles require regular software updates for battery, charging and drivetrain management. Individual function faults are only resolved by a dealer update.
Symptoms: Irregular charging stops, power reduction, warning messages on display that resolve after software update.
Vehicle Weaknesses 14
Mokka models (production May 2022 – March 2023) were recalled due to faulty high-pressure fuel lines. Loose connections allow fuel to enter the engine bay with acute fire risk.
The 1.2-turbo three-cylinder (Stellantis EB2) of the Mokka B uses a timing belt running in an oil bath, which can fail prematurely with incorrect oil spec or excessively long change intervals.
Already after 38,000–56,000 km the front axle ball joints show excessive play and are flagged at the MOT. According to TÜV statistics the defect rate is nine times above average.
LED headlights fail on individual units (fault codes B0984/B0985). No individual replacement of LED modules possible; entire unit for approx. 850–1,700 € plus fitting must be replaced.
LED headlights and tail lights of the Mokka B fail due to defective control units or wiring damage. Models from the first production years 2020–2021 frequently affected.
The infotainment occasionally stops responding; Bluetooth connections drop. Not all smartphone types connect reliably. Software updates only partially improve it.
According to TÜV statistics brake disc wear is clearly above the class average. Pads need replacing earlier than expected. Typical cost for full front replacement approx. 400–600 €.
The stop-start system of the Mokka B deactivates itself frequently without input. In addition, intermittent infotainment crashes occur, especially on cold start or after extended standstill.
Brake pads and discs on the Mokka B wear above average quickly, especially in city use. Front pads already at wear limit after 25,000–35,000 km.
On the Mokka B (CMP platform) rattling occurs at the front axle attributed to play in the steering column universal joint. Described by Opel as design-related.
On the Mokka B the tailgate strikes the boot lip when closing, causing paint damage. Manufacturing tolerance issue; Opel made corrections; early examples affected.
According to owners, the Mokka B has a thin factory body sealing. Body seams and wheel arch edges are considered susceptible after several winters.
On the Mokka B fault messages for the electronic parking brake system and the multi-collision brake assist are displayed without an actual fault. Software error.
The EAT8 8-speed automatic gearbox of the Mokka B shows juddering on the 2-to-3 shift and when pulling away. Torque converter cited as cause.
Reports & Tests
Suspension shows a significantly elevated failure rate — control arms and steering ball joints are flagged above average. Brake disc wear is higher than its predecessor. Electronic faults affect multimedia and emergency braking system warnings.
