There is something in the clutch system that is causing the clutch and other parts to burn fast and earlier than usual. The previous owner of my 2004 Nissan 350Z had the same problem. 2 new clutches at $2,500 each by the time it hit 35,000 miles. I bought the car not knowing about the problem and the clutch completely burned out while I was driving on the highway. Luckily I was not in the fast lane like I usually am and was able to safely pull over to the side of the road. I paid $2,500 to replace the clutch parts again. It is now less than 3 years later and it is happening again. Nissan dealer claims this must be user error and nothing wrong with the system yet agrees that is very hard to burn a clutch that fast as an experienced manual transmission driver. I've found others with the same problem but no resolution.

I purchased a 2004 Nissan 350Z roadster. The day after purchase I noticed a clanking noise when turning off engine. I took to my local dealer and was told this is normal. That was at 6500 miles. At the 15000 mile scheduled maintenance I reported that the problem is getting worse. Same response normal. There is nothing normal about it. I am worried that when the warranty is up it will all of a sudden not be normal and I will be stuck with the cost. I have read numerous complaints on the internet about this same issue with no Nissan response. Nissan needs to step up to the plate and provide some answers and assistance. I will be taking my car to the dealer now at 27000 and letting them hear how worse it has gotten also to have them repair the soft top that on the passenger side rear corner is just coming loose at the seems.

I have been hearing this rattle for a while already and I took the car to the dealer and they say is normal I don't think this is true. I have a 350Z Nissan I first bought it, it didn't do this noise. The thing that worries me about this is that it is a lot louder. I find that when I turn the car off you can hear the rattle louder and clearer. It look to me that is the throw-out bearing but I dont think they eant to do the job and the car still under warranty I dont know what to do. I already call Nissan but they dont do anything.

Shifting into 3rd gear will usually grind unless the clutch is held down extra long. All other gears are fine. Car has 4000 miles and the problem seems to be worsening with time. Nissan identified the problem as bad syncronizer and the manual transmission has to be replaced. I am now finding multiple reports of this problem on the internet. Very concerned because there are reports of the problem recurring.

I have a 2004 350Z coupe I bought it brand new in Sept.2003 assortment of problems that the dealer is unable to fix: 1. loud clutch chatter while car is idling and also when accelerating & decelerating in 1st & 2nd gear. 2. transmission clank when shifting gears feels like the tyranny is loose. 3. when car is idling the engine appears to be misfiring and engine is knocking. I have been having these problems ever since I purchased the car and 6000 miles later still not fixed.
