Nissan is recalling 247,266 units of the Serena (including S-Hybrid models), X-Trail and Juke in Japan fitted with direct-injected petrol engines over two separate defects in the fuel delivery system.

The first issue concerns the fuel pressure sensor on the fuel rail of both the MR20DD 2.0 litre and MR16DDT 1.6 litre turbo engines, which may have been improperly tightened. As such, the sensor might come loose due to engine vibrations, causing fuel leaks around the mounting point of the sensor.

Cars affected include 212,579 units of the C26 Serena and Serena S-Hybrid manufactured between November 15, 2010 and October 21, 2014, 10,508 units of the T32 X-Trail manufactured between November 22, 2013 and February 27, 2014, as well as 4,990 units of the Juke 1.6 DIG-T manufactured between November 28, 2011 and March 17, 2014.

Additionally, 41,940 units of four-wheel drive C26 Serena models manufactured between November 15, 2010 and October 21, 2014 have also been recalled due to a different issue concerning a defective high-pressure fuel pump. Due to faulty design, moisture in the fuel pipe could freeze in cold climates, possibly clogging up the fuel filter with ice.

In these conditions, the amount of fuel injected might be reduced, causing revs to become unstable and, in worst case scenarios, even stalling the engine while driving.

Nissan service centres in Japan will tighten the fuel pressure sensor to the proper torque, as well as replacing the high-pressure fuel pump with one of a different design.

Sources within Edaran Tan Chong Motor (ETCM) have confirmed that Serena S-Hybrid models sold in Malaysia have also been affected with the fuel pressure sensor issue, and we will report back with more details once an official statement has been released.
