Hey guys. I have a 2007 Maxima and I have developed a strange problem. Sometimes, not always, when my car reaches 2000 rpm, it makes a sqeaking noise from under the car. (it sounds like somewhere in the left front) The noise goes away when it gets past 2500 rpm. If I try to rev the motor in park, I can not recreate the sound, it only happens while driving. Any ideas on what this could be???

 

I'm getting the same noise. I've had it for over a year now.. I have no idea what it is. The dealer couldn't find the noise either

 

get some spray lubricant that is made for belts, spray the belts, then get some all purpose lubricate used for gears, and spray the gears. this should eliminate your noise. If it doesn't, at least your belts and gears are cleaned and conditioned.

 

I have a 2001 Maxima GLE. My car when reaches 2000 rpm, it makes a squeaking noise from under the car. (it sounds like somewhere in the left front). We found the noise to be under the car under the driver seat area. The noise was a broken ground wire that comes off the catalytic converter and connects to the chassis of the car which just happens to be around the under side of the car in the driver seat area. The broken wire resonated around the 2000 RPM. I removed the ground wire and no more noise around 2000 RPM. I did not replace the ground wire because the exhaust pipe to me is a ground by connecting to the engine block through the multiple exhaust pipes and bolts making connections between the pipe segments.
