Opel Mokka
Modern PSA/Stellantis four-cylinder with excellent fuel consumption, but structurally undersized camshaft chain (7 mm), subject to a mass recall with warranty extension to 10 years/240,000 km. AdBlue system and EGR prone to faults with short-trip use.
Mokka B diesel
81 kW diesel in the Mokka B – economical in everyday use.
Engine Weaknesses 5
The original 7 mm camshaft chain wears prematurely and can break, causing severe engine damage. Stellantis recalled over 141,700 vehicles in Germany alone. Warranty extended to 10 years/240,000 km.
Symptoms: Unusual knocking or rattling noises from the engine bay, especially on cold start. In the worst case sudden engine failure while driving.
The AdBlue dosing valve and the NOx sensor fail regularly. The pump and tank are one assembly and cannot be replaced individually, making repairs expensive.
Symptoms: AdBlue warning light on, engine management light active, elevated AdBlue consumption. Vehicle risks entering limp mode after several warning cycles.
The diesel particulate filter blocks with frequent short trips as regeneration temperature is not reached. A recall for approx. 1,100 Grandland X vehicles for defective DPF was carried out.
Symptoms: Heavy power loss, elevated fuel consumption, engine management light, smoke clouds when accelerating. Vehicle enters limp mode.
The EGR valve carbonises with frequent short-trip use. Typical symptoms are engine warning light, fluctuating power and black smoke. Cleaning or replacement necessary.
Symptoms: Engine management light, rough running, power loss under part throttle, black smoke when accelerating.
Instead of a proper gasket the DV5RD uses RTV sealant on the valve cover, which becomes porous over time. Oil leaks appear even on younger vehicles.
Symptoms: Oil smell in engine bay, visible oil stains on the valve cover and below, smoke if oil drips onto hot components.
Vehicle Weaknesses 13
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.
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.
