Opel Mokka B
Weaknesses, engine ratings and buying advice
The Opel/Vauxhall Mokka B (2020–2025) is no longer an Opel — it sits on the PSA CMP platform, same base as Corsa F and Peugeot 2008. Design polarises, tech is pure PSA. The central topic: suspension.
MOT report: Front axle ball joints fail 9 times more often than the class average — on the Mokka-e even 17.5 times. The higher SUV weight (~440 lbs more than the Corsa F) loads the identical CMP platform significantly harder. Repair $165–310, but due every 25,000–30,000 miles. Brake discs also wear above average.
Engine choice: The EB2DTS (1.2 PureTech Turbo, 74–100 kW) is the volume petrol — and has the notorious oil-bath timing belt problem: belt disintegrates in oil, engine damage without warning ($880–4,400). Affects model years 2020–2022, from 2023 timing chain. Coked intake valves from direct injection at 80,000 km (walnut blasting $330–880). Diesel DV5RD (1.5 BlueHDi, 81 kW) — frugal, unremarkable. Electric Opel-EM (Mokka-e, 100–115 kW) — no wet belt, no EGR, but suspension even more stressed by battery weight.
Fuel line recall: 30,810 vehicles (Nov 2022–Apr 2025), high-pressure line can leak → 11 vehicle fires documented. Check if completed!
Test-drive checklist: Ball joint play (clunking over bumps?), EB2DTS oil level, EAT8 cold 1→2 shift, display blackout test.
2026 market: 2021–2023 with 25,000 miles $17,600–23,100. Mokka-e $24,200–30,800. Insider pick: Mokka-e or EB2DTS from facelift 2023 (timing chain instead of wet belt).

Engine Overview
The Opel Mokka B is available with 3 engine variants — from 76 to 156 hp.
Modern PSA/Stellantis four-cylinder (1.5 L BlueHDi, 96 kW) with excellent fuel consumption, but a structurally undersized camshaft chain (7 mm width) that was subject to a mass recall with warranty extension to 10 years/240,000 km. When buying, absolutely verify whether the chain update has been carried out. AdBlue system and EGR are prone to faults with short-trip use. A capable long-distance diesel with genuine potential.
- !! Camshaft chain: premature wear (recall) from 70,000 km
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. - !! AdBlue system: pump, sensor and dosing valve from 60,000 km
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. - !! DPF blockage in short-trip operation from 80,000 km
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.
+ 2 more engine weaknesses + vehicle weaknesses
The PSA/Stellantis 1.2-litre turbopetrol with a wet timing belt is the most problematic engine in the current Opel generation. The belt can disintegrate with the wrong oil specification or an overdue service interval and block oil passages — with a serious risk of engine damage. Stellantis extended the warranty to 10 years/175,000 km. Used purchase only with a complete maintenance record and correct PSA B71 2312 oil specification.
- !! Wet timing belt disintegrates from 70,000 km
The timing belt running in engine oil swells with the wrong oil specification, becomes porous and generates abrasion. Particles block oil passages and oil pump – engine damage from lubricant starvation is the risk.
Symptoms: Oil warning light, engine stuttering, rough running, sometimes no warning before total engine failure. - !! Oil starvation from blocked oil passages from 80,000 km
Timing belt abrasion settles in fine oil passages and the oil pump strainer. Bearings receive insufficient lubrication – bearing damage and engine failure result, often without warning.
Symptoms: Oil pressure warning light, engine noise (knocking), sudden power loss, engine failure. - !! Wet belt degrades in oil – oil contamination from 60,000 km
The EB2DTS PureTech wet belt slowly abrades and contaminates the engine oil with rubber residue. These block oil passages and cause bearing seizure. Stellantis extended warranty to 10 years/175,000 km (service history required).
Symptoms: Black, rapidly degrading oil, oil pressure drop, engine noise from bearing starvation, in extreme cases engine damage at 50,000–80,000 km.
+ 5 more engine weaknesses + vehicle weaknesses
The PSA/Stellantis electric motor (100 kW / 136 hp) is fundamentally low-maintenance and free from classic combustion engine problems. However, sporadic drivetrain system faults are known that can lead to complete vehicle immobilisation — software updates have resolved many of these cases. The 50 kWh battery shows good ageing characteristics so far. The onboard charger (7.4 kW AC) and heat pump are occasional sources of faults.
- !! Electric drivetrain fault — vehicle blocked from 15,000 km
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 - !! Gearbox oil loss, reduction gear defective from 40,000 km
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 - !! OBC (onboard charger) defective — AC charging failed from 30,000 km
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.

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Ball joints wear prematurely 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. Symptoms: Knocking or rattling from the front axle, especially over bumps; MOT finding for play at ball joints from 45,000 km | Low |
Test Reports
AUTO BILD TÜV-Report
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.
