The third-generation of Nissan Altima (codenamed L31) debuted for model year 2002. It was the first mass-market product built on Nissan's new FF-L platform, which was unique to North America and had no equivalent model in Japan. (The Asian Nissan Teana is similar but not quite identical, slotting between the Altima and Maxima in size; all three lines would be sharing the same platform.) The Nissan Altima grew enormously for this generation, as interior volume expanded to 118.6 cubic feet. The Nissan Altima 's interior dimensions even surpassed that of the higher-end 2000-03 Maxima, so the 2004 Maxima was moved more upscale into the full-size bracket. Also biggest in class was the Nissan Altima 's 20-gallon fuel tank. The New Nissan Altima also upgraded its rear suspension to a multilink type and its brakes to 4-wheel discs.2003–2004 received two tone dash colour, as well as 245 hp (183 kW) and 249 lb·ft (338 N·m) of torque. Acceleration with the 5-speed manual was under 6 seconds at 5.9 with half a tank. 2002–2004 models with manual gearbox were the lightest of the V6 (4DR) cars.
2005–2006 Nissan Altima 2.5S
2005–2006 Nissan Altima SE-R
In 2005 the Altima received a facelift, including a new front grille, all-red taillights, redesigned interior, and an optional DVD-based navigation system. The V6 was now rated at 250 hp (186 kW), and its optional automatic was now a 5-speed. Also new was the SE-R model with a 260 hp (194 kW) version of the V6, a 6-speed manual transmission (automatic still optional), upgraded brakes, 18-inch wheels, a suspension even stiffer than that of the 3.5 SE's, and a high-flow exhaust.
Reception
The third-generation Altima was well-received by the press, with many critics praising the new style and extra space. It was one of the most powerful and best-handling family sedans available, making the nameplate competitive in the midsize segment for the first time. While previous iterations received decent reviews, the third-generation Altima was the first to enjoy considerable success, and it was credited with a turnaround of Nissan's operations. Most of the criticism centered on the interior, which was cited for using hard and brittle plastics. Some also found the steering too light and/or abrupt, and the turning circle wide due to the elongated wheelbase.
Additionally, numerous complaints have been filed with the National Highway Traffic Safety Administration related to the excessive oil and coolant consumption of 2002 Altimas with the 2.5 liter engine. This is often related to an inferior material used in the head gasket often resulting in massive failure of the head gasket resulting in both danger to the operator and major repair costs of between $2000 and $3000. Nissan maintains that this is not a recall issue and at some point, "the owner must take responsibility for the vehicle" even if damage was caused by design or material defects.

Third generation Altimas have been affected by a recall related to the intake manifold and the Power Valves, also known as the Butterfly Valve. The Technical Service Bulletin — Campaign Number P5202 — does not mention all affected vehicles for production years with the same intake manifold design. This has left some owners affected by the problem with no recourse or remedy for what in some cases has amounted to catastrophic engine failure.
The Power Valve is a series of four plates in the QR25DE 4-cylinder engine, one per cylinder. The plates open and close simultaneously to allow more air into the combustion chamber for increased power. Each plate is held in place by two screws. The screws have been known to come loose as well as the plates and are then ingested into the engine via the intake ports. Nissan's remedy has been to remove the intake manifold, and if the screws are present, remove them and apply loctite upon reinstalling the screws. Nissan has in some cases elected to replace entire engines, however on a selective basis.
Thousands of Altima 2002 had excessive Oil consumption caused by bad pre-cat design. Nissan is not responsible for that obvious problem.Article Directory : en.wikipedia.org
