"I've heard the new Mokka has the PSA timing chain problem." You have heard correctly — here is how to manage it.
The Mokka B switched from Vauxhall/Opel engineering to the PSA/Stellantis platform after the Peugeot-Opel merger. That brought genuine improvements — better interior quality, more modern technology, lower emissions. It also brought the 1.2 PureTech three-cylinder engine, which has a documented timing chain tensioner fault on pre-2022 production shared with the 208, 308, Corsa F, and Citroën C3. The buyer who knows about this can check for it, price it in, or target post-2022 cars with improved components. The buyer who doesn't know arrives home with a £7,500 car and a £1,200 chain job pending.
Mokka Mk1 (2012–2016): the reliable generation
The Mk1 Mokka uses GM/Vauxhall engineering — the 1.4 turbo (140ps) has a timing chain and no significant fault pattern beyond normal high-mileage wear. The 4WD option uses a simple viscous-coupling rear axle — effective for light off-road use, similar in concept to the Duster's system. The 1.7 CDTi diesel is reliable for motorway drivers but carries the standard DPF risk for urban use. The Mk1 interior quality is basic for the era, but the mechanicals are proven and well-understood by Vauxhall independents across the UK.
- Mk1 1.4 turbo (2012–2016): timing chain, no structural fault pattern — the safe Mokka choice.
- Mk1 1.7 CDTi diesel: reliable but check DVSA record for emission failures indicating DPF issues.
- Mk1 4WD: check transfer case fluid service history — same advice as Duster and HR-V.
Mokka B 1.2 PureTech: the same chain problem as the 208 and Corsa F — what the MOT history shows
The Mokka B (2021–present) 1.2 PureTech three-cylinder engine is identical in design to the engine fitted to the Peugeot 208, Peugeot 308 (pre-facelift), Citroën C3, and Vauxhall Corsa F. On cars produced before mid-2022, the original chain tensioner design has a documented failure mode — the tensioner weakens over time, allowing the chain to develop slack, which produces a rattle on cold start. Left unaddressed, the chain can jump or snap. PSA/Stellantis introduced a running improvement (stronger tensioner, revised chain guide) from approximately mid-2022. A chain and tensioner replacement on the Mokka B costs £600–£1,200 at an independent. This shows in the MOT/DVSA record as engine advisory notes — 'engine noise', 'timing chain rattle' or similar. A Mokka B with clean MOT tests and no engine advisories is not guaranteed fault-free, but one with multiple engine noise entries across tests has been running with this problem. Run the free check before you travel.
- Pre-mid-2022 PureTech: cold-start chain rattle check is mandatory. Budget £600–£1,200 if present.
- Post-mid-2022 PureTech: improved tensioner — lower risk, still worth a cold-start inspection.
- MOT history: 'engine noise' advisories on a Mokka B are the chain problem in writing — negotiate hard or walk away.
Mokka-e electric: battery state of health is the price-determining factor
The Mokka-e (electric, launched 2021) shares its platform and 50kWh battery with the Peugeot e-208 and Citroën ë-C4. Real-world range is 190–220 miles on a full charge. As with all BEVs, battery state of health (SoH) degrades over time and charge cycles. Before buying, request a battery SoH diagnostic — either via a main dealer or a specialist with PSA diagnostic tools. A reading of 90%+ is healthy. Below 85% means noticeably reduced range and lower resale value. Rapid DC charging more than 80% of the time accelerates degradation.
What your budget actually buys
At £4,500–£7,500 you're in Mk1 territory — 2013–2016 cars with 50,000–90,000 miles. 1.4 turbo is the buy here; diesel only if the emission history is clean. At £8,000–£13,000 late Mk1 and early Mokka B overlap — a post-mid-2022 Mokka B 1.2 PureTech at the top of this range is the preferred choice. At £13,000–£19,000 low-mileage Mokka B and Mokka-e — battery SoH check essential on the electric.
The takeaway
A pre-mid-2022 Mokka B without a cold-start chain check and a clean MOT engine advisory record is a risk the asking price doesn't reflect. Post-mid-2022 cars are safer. The DVSA check takes two minutes and tells you whether the problem is already documented on this specific car.

Frequently asked questions
Frequently asked questions
Does the Vauxhall Mokka B have a timing chain problem?
The 1.2 PureTech engine fitted to pre-mid-2022 Mokka B cars has a documented chain tensioner fault shared with the Peugeot 208, 308, and Corsa F. Post-mid-2022 production received an improved tensioner. Always check the build date and do a cold-start inspection before buying any Mokka B.
Is the Mokka Mk1 reliable?
Yes — the Mk1 1.4 turbo is a proven, reliable engine with no significant fault pattern. The main checks are transfer case fluid service on 4WD models and DPF history on the diesel. The Mk1 is the lower-risk Mokka generation.
Should I buy a Mokka B petrol or electric?
Petrol for buyers who don't want to manage charging. Electric for buyers with home charging and primarily urban or suburban use — the Mokka-e's 190–220 mile range is adequate for most daily use. Always check battery SoH before buying any Mokka-e.
Is the Vauxhall Mokka good for families?
The Mokka is a five-seater with a 350-litre boot — adequate for small families. It's smaller than a Kuga or Qashqai. If you regularly carry three adults in the back, the Qashqai or Kuga offer more rear room. For couples and small families, the Mokka's size is practical.
