Is the Citroen C4 Grand Picasso reliable?
The Citroen C4 Grand Picasso has 5 known faults in our database across 2 generations, 1 of them rated high severity. The most serious are cooling system (the water pump fails early and, because the timing belt drives it) and suspension (the self-levelling rear suspension's air units fail so often that by 2011 the failures). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
Which Citroen C4 Grand Picasso years should you avoid?
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.

Generation 1 of 25 known faults
Citroen C4 Grand Picasso Mk1 (2007 to 2013) problems
SuspensionMedium severity💬 10 owner reports, 2011 to 2019
The self-levelling rear suspension's air units fail so often that by 2011 the failures were described as an epidemic, with parts on back order for six weeks, and in 2013 about 1,500 were on back order in the UK. Citroen said the fault affects Exclusive seven-seat cars with the pneumatic rear springs. The rear drops and takes a very long time to pump back up, or only comes up if the car is driven slowly or a door is opened and shut. After a BBC Watchdog investigation in 2014 Citroen agreed to pay 80% of the cost of replacing the units on cars under ten years old and 120,000 miles, and was still offering up to 80% in 2018 where the car had always been dealer serviced; one owner had a failed unit replaced at a subsidised £75 and was then quoted £1,158 for the compressor.
Rough guide
£400-1500
Typical symptoms
rear of the car sitting low, especially overnight or loaded
suspension slow to rise after starting
warning beep or message about the rear suspension
compressor running constantly
Affected vehicles
Engines:
Cars with the pneumatic self-levelling rear suspension (Citroen said the Exclusive seven-seat models); not cars on steel rear springs
Typical mileage:
40000-90000 miles

Transmission/ClutchMedium severity💬 6 owner reports, 2014 to 2020
The EGS automated manual can wear out its clutch in as little as 24,000 miles, and because the system rather than the driver works the clutch, an early failure is worth arguing as a warranty matter. Owners reported a clutch failing at 67,000 miles (£715) and the system failing again at 78,500, violent juddering at 90,000 miles, an actuator leaking fluid on a 2012 car within 30 days of purchase, a 2007 2.0 HDi whose actuator switched to manual and then limp mode, another 2.0 HDi continually changing down, and a 65,000-mile 2010 car with a failed clutch actuator and a leaking slave cylinder, for which a dealer quoted £3,500 for actuator, clutch and flywheel.
Rough guide
£700-3500
Typical symptoms
violent judder pulling away
gearbox switching itself to manual mode or limp mode
fluid leaking from the clutch actuator
continual unwanted downchanges
Affected vehicles
Engines:
1.6 HDi and 2.0 HDi with the EGS automated manual gearbox
Typical mileage:
24000-90000 miles
🔍 We have a specific pre-purchase check for this faultCheck an advert →
Engine/EmissionsMedium severity💬 6 owner reports, 2013 to 2017
The 1.6 HDi loses its turbo through coked oil feed pipes: at 30,000 miles on a 2008 car and at 66,000 on another, and a repeat failure followed where the feed pipe was not replaced with the turbo. Letting the engine idle for a while from hot before switching off helps. The injectors also fail: one at 37,000 miles, with advice to replace all four, and repeatedly on a 10,000-mile 2011 car, while a 40,000-mile 2012 HDi had two separate injector failures before its water pump failed and broke the timing belt.
Rough guide
£800-2500
Typical symptoms
whistle or siren from the turbo and loss of power
blue or black smoke
misfire or rough idle from a failed injector
engine warning light
Affected vehicles
Engines:
1.6 HDi diesel (DV6)
Typical mileage:
10000-70000 miles

CoolingHigh severity💬 2 owner reports, 2011 to 2016
The water pump fails early and, because the timing belt drives it, takes the belt with it and wrecks the engine. The 2.0 petrol was flagged for this in 2011, and a 40,000-mile 2012 HDi lost its belt this way after two injector failures. A new water pump with every belt is the only protection.
Rough guide
£400 for pump and belt, 3000-5000 after a failure
Typical symptoms
coolant leak or weep from the pump behind the timing cover
grinding or rumble from the belt area
sudden engine stop with a bang
Affected vehicles
Engines:
2.0 16v petrol and the HDi diesels, whose timing belt drives the water pump
Typical mileage:
40000-70000 miles

BrakesMedium severity💬 2 owner reports, 2015 to 2016
The electric handbrake fails: a 2007 car could not release it, with the speedometer showing dashes and hours of diagnosis, and a 2008 car's handbrake failed at 80,000 miles with £1,000 to repair both sides.
Rough guide
£500-1000
Typical symptoms
handbrake refusing to release or apply
handbrake warning with other dashboard faults
grinding from the rear as the motors work

Citroen C4 Grand Picasso buying questions
What are the most common Citroen C4 Grand Picasso problems?
Three stand out. Cooling system: the water pump fails early and, because the timing belt drives it, takes the belt with it (typically 40000 to 70000 miles). Suspension: the self-levelling rear suspension's air units fail so often that by 2011 the failures were (typically 40000 to 90000 miles). Gearbox: the EGS automated manual can wear out its clutch in as little as 24,000 miles (typically 24000 to 90000 miles). The full list above is grouped by generation, with typical mileage and a rough repair cost for each.
Which Citroen C4 Grand Picasso years should I avoid?
No Citroen C4 Grand Picasso year is a write-off, but the Mk1 (2007 to 2013) carries the most serious faults: cooling system. The Mk2 (2014 to 2018) has none rated high severity. Year matters less than whether the specific car has had the known fixes, so check the history for them.
What should I check when viewing a used Citroen C4 Grand Picasso?
Ask the seller about the cooling system, suspension and gearbox faults on this page and whether they have been fixed, with invoices. On the test drive watch for coolant leak or weep from the pump behind the timing cover, rear of the car sitting low, especially overnight or loaded and violent judder pulling away. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 5 known faults before you travel. Check a Citroen C4 Grand Picasso advert →
