The base car is quite basic, but options on the other models include keyless start, rear disc brakes and, on the Spec V, a limited-slip helical differential and a 2.5L engine tuned for 200 hp. Specifications given here are for the base model.
The Continuously Variable Transmission (CVT) is available on all models except the Spec V, and it requires special transmission fluid sold only by Nissan. No power steering fluid is required because the car has electric power steering. Maintenance is pretty simple, except for valve adjustment, which requires replacing the lifters. Fortunately, the camshafts are easily removed.
A safety recall was issued to replace a faulty brake master cylinder (Bosch part only). Another recall was issued to replace a fuse cover decal on the back of the sunglasses holder. The existing decal incorrectly specifies a 15-amp fuse for the stop lamp, but the fuse holder is supposed to get a 10-amp fuse. A service bulletin was issued to address a rattle in the variable valve timing sprocket, which may be an indication of oil pressure problems. Another bulletin says MIL illumination with P0128 (thermostat) may be caused by faulty PCM software.
Historically, the Altima and Sentra have been Nissan's bread-and-butter cars in the North American market. Part of the reason is that with proper care, both models tend to remain in service for a long time. That makes used powertrain components readily available, making it possible to keep the car alive even longer. This all means it's worth convincing a customer to take care of the small stuff, too.
