Nissan Pulsar

A number of owners report the 1.2 DIG-T petrol burning through oil fast, in one case 1.5 litres in 6,000 miles. Dealers have blamed worn piston rings and in some cases pushed a software update, with a handful of cars needing a reconditioned or replacement engine. No public recall or TSB was found for it, so it looks like a workshop-level fix rather than an acknowledged campaign.

Separate owner reports describe the timing chain pulley on the 1.2 DIG-T failing, in one case twice within six months on a car barely a year old. It is not the timing chain itself stretching in the classic sense, it is the pulley/tensioner hardware, and it has shown up early enough that most cases were still in warranty. Worth asking whether any chain work has already been done under warranty, since a repeat failure out of warranty is a proper engine-out job.

Owners report rear suspension parts wearing enough to cause an MOT failure on higher-mileage cars, and this lines up with the measured MOT signature for this segment, where suspension is the standout fault category. Expect bushes, links or springs on the rear axle to be the weak point rather than anything at the front. Bank on £150-400 for parts and labour if it needs doing, more if a strut or spring has to come with it.

The built-in satnav on some cars intermittently blanks the screen and recalculates the route mid-journey. Nissan support acknowledged the fault when it was reported but had no fix to offer, so it is a known, unresolved software gremlin rather than a one-off unit fault. A full head unit replacement sometimes clears it, but there is no guarantee.

Two separate owner reports describe clutch trouble very early, one at 6,000 miles and one at 22,000 miles, with the dual-mass flywheel also damaged in at least one case. That is well before normal clutch wear should show, so a heavy or juddery clutch on a low-mileage manual is worth taking seriously rather than assuming it is driver wear. Doesn't apply to cars with the Xtronic automatic.

A scatter of reports covers central locking failing on individual doors, air-con packing up after a routine service, and stop-start throwing false alarms on steep hills. None of these look like a single named fault, more a general pattern of niggly electrics that owners put down to the Pulsar sharing wiring and systems with the second-generation Qashqai, a car criticised for patchy build quality. Most were sorted under warranty, so it is more of an annoyance than a big bill if the car is still covered.
