The Vauxhall Mokka was Vauxhall's first proper crossover SUV and sold strongly throughout the 2010s. It's a compact, practical car but has a number of well-documented reliability issues — particularly the 1.6 CDTi diesel and the 6-speed automatic gearbox, which have generated significant owner complaints.

6 Most Common Vauxhall Mokka Problems
These are the faults most frequently seen on the Vauxhall Mokka by UK garages — ranked by how commonly they occur and how serious they are.
The 1.6 CDTi diesel engine used in the Mokka has a known timing chain issue — a rattling noise on cold start is the warning. GM/Vauxhall extended the warranty on this fault but it still affects many out-of-warranty cars. Engine damage is the consequence of ignoring it.
💷 Typical repair cost: £800–£2,000
The 6-speed automatic gearbox fitted to petrol Mokkas has been the subject of widespread complaints — shuddering, jerking and hesitation when pulling away. Gearbox fluid changes at 40,000 miles help but hardware faults do occur.
💷 Typical repair cost: £500–£2,000
EGR valve faults are common on Mokka diesels — rough idle, loss of power and EML are the typical symptoms. Cleaning is effective in early stages.
💷 Typical repair cost: £150–£380
Injector seal failures on the 1.6 CDTi engine allow exhaust gases into the engine bay — white smoke, burning smell and rough running are the symptoms. A relatively common fault on higher mileage examples.
💷 Typical repair cost: £300–£700
AC compressor failures are more common on the Mokka than most competitors — no cold air or a clicking noise when the AC is engaged are the symptoms.
💷 Typical repair cost: £350–£700
Rear suspension link and bush wear is common on higher-mileage Mokkas — clunking over speed bumps and MOT advisories are the typical outcome.
💷 Typical repair cost: £120–£300
