Neutral safety switch - Sometimes will not start in Park, must switch to Neutral, might need an adjustment.
Loud Idle - Sounds like a clatter from the top of the engine. Valves? Lifters?
Evap canister vent control valve - Cleaned the hoses, it has not returned.
Does not like harsh roads, might need new struts soon.
I bought this car back in 2003, it was black with leather interior. The first time I drove it, the car ran like it was brand new. I could not hear the engine running from inside the cabin. I loved the performance of the car, especially on the interstate. Handling and steering was decent for a front wheel drive car.
A few months later it started getting colder out and developed a rough idle when I started it up. I was disappointed as I liked the smooth idle of the engine and it was a big selling point for me. My best guess is that the previous owner missed an oil change or beat the hell out of it. I replaced the coils and plugs (NGK) but it still ran the same.
The car is still running fine today with the rough idle. It has never failed to start except when I left a light on inside and ran the battery dead. I have run it over 80mph consistently on the interstate and still get 25-26 MPG (using 91 octane) which is nice. In the winter I get 22-24 MPG, maybe because of the fuel formula being different in the midwest. The auto trans shifts fine, when its cold it is not as smooth, but the manuals suggest this is normal. I have no electrical problems.
If I had to buy one again, I would, but with some reservations. The 99-01 Maxima had a problem with bad ignition coils. This is usually an easy DIY job to fix. Also, be sure you only use NGK plat spark plugs. If you have the auto trans, it might be a good idea to inspect the fluid or change it. The leather seats are comfortable and I really like the interior overall. Mine came with factory wood trim...it's not real, but looks decent. A factory service manual might help with various DIY repairs.
