Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

My 2004 Nissan 350Z with 36,000 miles uses one quart of oil every 500 miles. My factory powertrain warranty expired January 31, 2009 (34 days ago). Nissan is not illing to 'goodwill' my complaint even though the vehicle is 14,000 miles below the factory mileage warranty of 50,000 miles and the fact that this issues began months before January 31, 2008.

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.
