An early car in the generation · most of the launch teething issues were still being worked through, so recall completion and dealer rectification history matter. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2016 car has usually reached the mileage where they appear.

Faults a 2016 example has usually reached
Documented onset mileage is at or below the ~135k miles an average 2016 car has covered.
EngineHigh
1.4 turbo (Mokka A) chain and water pump wear
- Typically appears
- 70,000+ miles
- What to inspect
- Cold-start listen and coolant inspection
SuspensionLow
Front bushes and drop links knocking
- Typically appears
- 60,000+ miles
- What to inspect
- Listen over speed bumps and check for uneven front tyre wear
Engine (1.6 CDTi Diesel Mokka A)High
Loud metallic rattling on cold start from the gearbox side of the engine.
- Typically appears
- 70,000-100,000 miles
- What to inspect
- Open the bonnet and perform a cold start. Listen closely to the rear right of the engine block (flywheel side) for a sharp clatter lasting 3-5 seconds before oil pressure builds.
Engine (1.4 Turbo Mokka A)Medium
High-pitched whistling noise at idle, rough running, and excessive crankcase vacuum.
- Typically appears
- 60,000-90,000 miles
- What to inspect
- With the engine idling, attempt to remove the oil filler cap. If there is heavy suction resistance and the whistling stops once the cap is off, the rocker cover PCV membrane has failed.
Drivetrain (4x4 Models Mokka A)Medium
Drivetrain binding, juddering, or groaning noises from the rear axle during tight turns.
- Typically appears
- 50,000-80,000 miles
- What to inspect
- Perform a tight figure-of-eight manoeuvre on the forecourt at low speed on full lock. Feel for any hesitation, juddering, or groaning from the rear differential and transfer box.
Faults that appear at any mileage
Age, electronics and build-related issues that are not mileage-driven.
ElectricalMedium
Battery drain and infotainment resets on Mokka B
- Typically appears
- Any
- What to inspect
- Leave the car locked, then check for a slow crank; test the screen
Climate Control (Mokka A)Medium
Cold air blowing from the passenger side vents despite the heating being turned up.
- Typically appears
- 6-9 years
- What to inspect
- Run the engine to operating temperature, set the climate control to maximum heat, and place your hands over both the driver and passenger air vents to check for uneven temperature distribution indicating a blocked heater matrix.

Is the electric Mokka worth stocking?
Yes if battery health checks out; it retails well in urban areas with charging.
What is the wet belt risk?
Belt material breaks down and blocks the oil pickup, which can end the engine. Paperwork is everything.
Which Mokka moves fastest?
Mokka B in a bright colour with low mileage and a full service history.
Are the diesel Mokka A models ULEZ compliant?
Yes, provided it is the 1.6 CDTi 'Whisper' diesel introduced in 2015, which meets Euro 6 standards. However, the earlier 1.7 CDTi units from 2012 to early 2015 are Euro 5 and will incur ULEZ charges. Always verify the V5C emissions standard before advertising a diesel model to urban buyers.
What should I look out for on the Mokka A automatic gearboxes?
The six-speed torque converter automatics are generally robust but highly sensitive to fluid degradation. Check for harsh engagements when shifting from Park to Reverse or Drive on the forecourt. If the vehicle shudders during gear changes, it likely requires a fluid flush, which many previous owners neglect.
How do the Mokka A and Mokka B differ in platform reliability?
The Mokka A sits on a legacy General Motors platform, meaning replacement parts are cheap but it suffers from older GM electrical gremlins. The Mokka B uses the Stellantis CMP platform. While the B offers vastly improved driving dynamics and tech, it introduces Stellantis-specific powertrain quirks requiring stricter maintenance.
