The 2.5-liter engine Nissan QR25DE has been produced in factories in Japan and the United States since 2000 and used in popular models such as Altima, Caravan, Frontier, and X-Trail. The engine underwent significant upgrades in 2007, which is why some distinguish between two generations of this engine. The QR family also includes the following engines: QR20DE, QR20DD, QR25DD, and QR25DER.

The weight of the QR25DE engine according to the catalog is 121 kg. The engine number QR25DE is located at the junction of the block and the gearbox. The engines produced before 2004 were equipped with not very durable catalytic converters, which quickly deteriorated, and their particles were sucked into the engine combustion chambers. Also, engines before 2006 had an intake manifold with throttle turbulators, the bolts of which would come loose and end up in the cylinders with similar consequences. Oil consumption: Most complaints from owners of this engine are somehow related to oil consumption. The reasons include not only cylinder scoring but also wear of oil control rings and clogging of thin oil scraper rings, which often occurs before reaching 100,000 km. At high mileage, significant elliptical deformation of the cylinders can also occur. Timing chain stretch: The thin plate chain Morse also has a relatively low lifespan here; it can critically stretch and start making noise as early as 150,000 km of mileage. Often, it is recommended to replace the phase regulator with the chain, but it can also be simply cleaned. Cylinder head gasket failure: Another common problem here is the regular failure of the cylinder head gasket. The culprit is usually the failure of thermostats or radiator contamination. In this case, deformation of the cylinder head is often encountered, and sometimes microcracks appear. Other breakdowns: Unreliable camshaft and crankshaft position sensors, a rather glitchy electronic throttle, as well as constantly leaking spark plug well seals, can cause a lot of trouble. And don't forget to adjust the valve clearances; there are no hydraulic lifters here.

The 1.3-liter Nissan QG13DE engine was produced in Japan from 1998 to 2012 and mainly installed in local models, as well as in cars intended for the market of Southeast Asian countries. This power unit is the smallest in the lineup and practically does not occur in our country. The QG family also includes the following engines: QG15DE, QG16DE, QG18DE, and QG18DD.
The 3.0-liter engine Nissan VG30DE was produced by the company from 1986 to 2000 and was installed in both civilian cars and popular sports models of the 300ZR and 300ZX family. The power unit was offered in a wide range of power outputs and equipped with variable valve timing. The 24-valve engines from the VG series include: VG20DET, VG30DET, and VG30DETT.
The 3.5-liter Nissan VQ35DD engine was first introduced in 2016 and was intended for the popular Pathfinder crossover and its Infiniti counterpart, the QX60. The engine is equipped with a proprietary direct fuel injection system and variable valve timing on both camshafts. The following engines belong to the VQ series: VQ30DE, VQ30DET, VQ30DD, VQ35DE, VQ35HR, and VQ37VHR.
