FYI - just got a recall notice in the mail. Nissan is saying that 'some' 2000-2003 model year Nissan vehicles are affected (they did not mention the Maxima or any specific models)
It says there is a possibility of the crank position sensor malfunctioning while the engine is on, and that the engine may stall while driving if the sensor fails. It also may cause an SES light or reduced power before it is bad enough to stop the engine.
Nissan says to have your car inspected as soon as possible if you have an SES (service engine soon) light. Otherwise make an appointment when convenient to have the crank sensors replaced.
If you didn't get the letter, your car probably isn't affected, but I would guess that since it is a 2000-2003 issue, a lot of us will be getting these notices!
