Normal driving in air temperatures above 80 degrees. Failure in the clutch petal pressure- unable to disengage the clutch and shift gears. Had fluid flushed however this did not solve the issue and so the master and slave cylinder were replaced as recommended by manufacturer. One year later the issue returns, fluid was flushed and replaced with a high grade clutch fluid (dot 4) however still did not solve issue. Master and slave will be replaced again. This link below will show the number of people who have had problems with the clutch pressure. www.nissanclub.com/forums/2005-2006-Nissan-Altima-SE-R-discussion/229124-class-action-lawsuit-clutch-problem.html.

The clutch pedal on my 2002 Nissan Altima 3.5se inexplicably and without warning, falls to the floor and becomes inoperable while driving. This happens intermittently, especially during 'stop-and-go' traffic. The pedal simply does not return to its normal position. It is impossible to replicate the symptoms for my mechanic, who gave the clutch a clean bill of health. Once it failed me at 60 mph!!

I belong to www.nissanclub.com and many owners of the Nissan Altima with manual transmission from 2002 to current 2006 models have had premature master/slave cylinder failures which are a safety hazard when you can not shift your car into or out of gear while in motion. Many of us find ourselves in a panic mode when we can not stop or go because our clutch pedal has no pressure and we can not shift out of gear while driving. My personal incident involves me having no ability to shift while in any driving situation, such as parking lots and up to highway driving. I nearly got hit while driving South then making a left turn (West) when I could not shift into second and another car was coming in the opposite direction (North). I had to rev my car to redline just to make it past the intersection. If you go to nissanclub.com you'll find may people who have had failures with the manual transmission.

Clutch was noisy. Clutch began slipping at 30K miles. Drove vehicle to the dealership. Paid over $700 for new clutch. Discovered there is a service bulletin on this vehicle for a replacement clutch with updated friction material. Was wrongfully advised by dealership that the clutch needed replacement due to poor driving habits.
