Citroën C4 Picasso / Grand C4 Picasso (Mk2)
This is one of the most practical family MPVs of the last decade, and still a clever used buy if you choose the engine carefully. The big used-car divide is between petrol wet-belt risk, diesel AdBlue exposure and the quality of the car’s touchscreen-driven cabin electronics.

Common Faults & Reliability
These are the most common documented problems for the Citroën C4 Picasso / Grand C4 Picasso (Mk2), sorted by their typical impact and frequency.
1.2 PureTech "Wet Belt" Degradation
high severityThe timing belt runs in oil and can degrade, shedding debris that blocks the oil pickup. This leads to oil starvation, vacuum pump failure, and a dangerous loss of braking assistance (Recall R/2020/331).
BlueHDi AdBlue tank and NOx-sensor faults
high severityLater diesels can throw UREA warnings, emissions faults and no-start countdowns when the SCR system, tank or NOx sensors begin to fail.
Touchscreen and parking-brake glitches
medium severityThe touchscreen controls so much of the cabin that lag, black screens or electronic parking-brake faults are more than minor annoyances on an everyday family car.
