A 2014 to 2022 Citroen C4 Picasso is the safer era, but no engine's a clean pick, so buy on paperwork (AdBlue repair bills on a diesel, belt and software records on a PureTech) and skip the jerky automated manual.
3 known faults, 2 rated high severity in our database. Everything below is built from that data and the archived owner history, not from a press car.

The 1.6 BlueHDi diesel from 2014 and the 1.5 BlueHDi from 2017 both carry a serious AdBlue fault, so a diesel that's already had its new tank, pump and injector, with the bill, is the better bet. Pair any engine with a proper manual or the EAT6 torque converter automatic, not the jerky automated manual option.
The 1.2 PureTech petrol carries a High known fault on 2014 to 2023 cars: its cambelt runs in oil, and worn belt material can block the oil pickup, leading to oil starvation and a failed brake vacuum pump. The belt's due at 62,000 miles or 72 months with a check at every service, and several owners have had serious engine trouble, including a new camshaft and a car that went through two replacement engines. Only buy one with belt paperwork and proof the engine software update's been done.
The older car (2004 to 2011) is the riskier purchase. Its EGS automated manual gearbox has a long record of juddering, worn clutches and failed actuators, the 16-valve 1.6 HDi diesel can starve its turbo of oil, and the seven-seat Grand Picasso's rear air suspension has failed on a lot of cars. If budget forces you into one, find a manual that's already had the suspension sorted.
Neither later engine family is safe. The 1.2 PureTech escapes the AdBlue fault, but its oil-bathed belt carries a High known fault of its own, shedding material that blocks the oil pickup, and it's due at 62,000 miles or 72 months with a check at every service. Owners have reported serious failures too: an engine that shut down on the move, carbon pitting on the valves, and a warning two replacement engines didn't clear. An older PureTech 130 needs its ECU update on record.
Don't buy a 1.6 BlueHDi (from 2014) or 1.5 BlueHDi (from 2017) unless the AdBlue work's already been done. The pump sits inside the tank, so the fix is a whole new tank, pump and injector, and it's turned up between 22,000 and 28,500 miles. One owner of a 2015 car paid £1600 for exactly that job. The 2.0 BlueHDi isn't named in that fault, but there's too little on record about it to call it safe.
On the older car, the 16-valve 1.6 HDi diesel's turbo oil feed pipe clogs with carbon, and the turbo can fail anywhere from 30,000 to 100,000 miles. Its cambelt and water pump are due together at 87,000 miles or 10 years, while the 2.0 HDi goes to 125,000 miles or 10 years. Several 1.6 HDi owners have also had injectors fail, and one 2011 car (engine not stated) lost three of its four.
Whichever era you're buying, don't take the automated manual gearbox (EGS on the older car). Its clutch has been known to wear out by 24,000 miles, and owner after owner describes judder pulling away, hunting between gears, actuator leaks and limp mode. A proper manual or the later EAT6 automatic avoids all of it.
Scan the dash with the engine running on any BlueHDi: an AdBlue or UREA warning, or a countdown saying the engine won't restart, means the tank, pump and injector are due. Ask whether it's had a new tank, and get the bill that proves it. On a PureTech, ask for the wet belt receipt if it's past 62,000 miles or six years, plus proof of the ECU software update. A low oil pressure light or a hard brake pedal on a PureTech points to the belt.
On a Grand Picasso with rear air suspension, park it and come back later. A rear end that's sagged, takes ages to pump itself back up or shows a Suspension Faulty message has a sphere, airbag or compressor on its way out. Try the electric parking brake several times too, because owners have had them stick on and fail on both sides, one paying £1,000 at 80,000 miles.
Drive it from cold. On an automated manual, shudder in first gear, lurching at a steady speed or a gearbox warning points to the clutch or actuator; one owner paid £715 for a clutch at 67,000 miles and the system failed again at 78,500. On a 1.6 HDi, listen for a whistle from the turbo, and if one's been fitted, check the invoice also covers the oil feed pipe.
Look over the auxiliary belt, which has worn out or snapped by 12,000 to 22,000 miles on some later cars and can take the timing belt with it if it comes off. Check the air conditioning blows cold, as condensers have cracked and regassed systems have leaked. Lift the fusebox lid on an older car for damp, and on a 2016 or 2017 car ask whether the bonnet recall was carried out.
Paste the advert into the free check and it runs these against the listing, the MOT history and the DVLA record before you travel.
Only as a manual, and ideally not the 1.6 HDi; the EGS automated manual is the version to leave alone. That gearbox's clutch has worn out as early as 24,000 miles, and owners describe judder pulling away at 12,000 and 32,000 miles, a car that stopped dead in the road, and one actuator that kept leaking fluid onto the driveway every few months.
The 16-valve 1.6 HDi has seven owner reports behind its turbo fault. Carbon chokes the pipe carrying oil to the turbo bearings, so the turbo fails, and a new turbo fitted without a new feed pipe and a clean oil supply can go again within 10,000 miles. One owner's turbo failed at 30,000 miles, another's at 66,000. Let it idle for a while after a hard run before switching off.
Seven-seat Grand Picasso versions use rear air suspension, and a long run of owners have had it fail, one at 45,000 miles, with the spheres often to blame and the car dropping at the back and taking an age to rise. Parts were once on back order for weeks. The electric parking brake has also let owners down, and the 1.6 HDi's plastic dipstick can snap off and fall into the sump, which then has to come off.
It's still a clever, roomy family car when it's sorted. Injectors on the 1.6 HDi have failed on low-mileage cars, one at just 10,000 miles, so ask what's been replaced. The big windscreen also picks up reflections from oncoming headlights on wet nights, which is worth knowing before a long evening test drive.
Yes, but only with the paperwork for its engine's weak spot, and with a manual or the EAT6 automatic. A BlueHDi diesel needs proof of AdBlue repairs, and a 1.2 PureTech needs belt and software records. The AdBlue tank, pump and injector fault on the 1.6 and 1.5 BlueHDi has turned up at 22,000 to 28,500 miles, and a warning left alone ends in a car that won't restart.
The PureTech petrol drives nicely with the torque converter auto, and the lighter engine helps the ride and handling. Its weak side is the engine itself: owners have reported a camshaft and carbon pitting repair, one car that needed two replacement engines and another that shut itself off at speed. Its oil-bathed belt is a High known fault, so it needs to have been kept to 62,000 miles or 72 months, with a check at every service.
The diesels' belt also matters. On the 1.6 BlueHDi it's a dry belt that drives the water pump, due at 60,000 miles or 60 months, and one 2015 car, thought to be a diesel, lost its engine at 57,000 miles when the water pump failed and the belt came off. One owner of a 1.6 e-HDi paid £500 for a failed injector.
Several recalls apply. A 2017 recall checked a starter motor relay that could overheat and even catch fire, the bonnet's inner skin got extra adhesive on 2016 and 2017 cars, and some late 2017 cars got a new airbag ECU. One 2014 Grand Picasso also had its clutch master cylinder replaced under recall. Beyond that, owners have logged electrical niggles, a cracked tailgate and air conditioning condensers that failed.

The middle row is three separate seats rather than a bench, so each passenger gets a place of their own, and all three will take a child seat, which matters if you've got a young family.
The rear seats are simple to fold, and on the later car they slide as well as fold, dropping to leave a flat load floor once they're down. There are plenty of clever little touches around the cabin, and on the later car every one of the five seats is an individual chair rather than part of a bench.
