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.

I purchase this vehicle as second owner with 24,000 miles. After a 2 years of using this vehicle on the weekends, I start hearing the 5th gear grind. I did not paid to much mind because it did it now and them, not every time. 4 years down the road, it did it more often and I knew it was in for transmission problems.. about a week ago my 3rd gear made a vibration and a horrible sound and that was when I knew something really wrong was going on.. today my car lost 3rd gear, it won't take, after I put the vehicle on 3rd I accelerated and nothing happens. 5th gear still grinds and but still work. It is not my clutch because 1st 2nd 4th and 5th and 6th still very strong pull.. now I'm driving this car to work, getting money together waiting for the break down or transmission lock... I feel unsafe on the road, but I do have to get to work I have no other choice at the time. I hate mistreating my Z this way.... 49,500 miles on the transmission..

I own a 350Z bought brand new in 2003. I was one of the 1st in baltimore for I did not see another Z for six months. I have had a new transmission put in at 36K due to a failing 3rd gear synco and now at 80K the 5th. I am about to put in my 5th window motor in. Nissan does not care about us so don't even waste your time with 1800nissan1. They should feel privileged that we allow Japanese to sell cars here in the us and should be penalized when they fail. I will never ever buy a Nissan again and I go as far as getting my Nissan's oil changed at Toyota so I do not promote Nissan any further. Quite a lemon. Tacoma has 90K and only oil changes.

The contact owns a 2003 Nissan 350Z. While driving 40 mph, the vehicle loses speed whenever he shifts gears to accelerate. The engine revs, but the vehicle does not accelerate. The contact took the vehicle to the dealer numerous times, but they were unable to diagnose the cause of the failure. They have changed numerous sensors, the engine computer, and even the water pump of the vehicle. Through online research, he discovered NHTSA campaign id number 03V455000 (engine and engine cooling); however, Nissan stated that his VIN was not included in the recall. He has been unable to drive the vehicle due to the lack of acceleration. The failure mileage was 80,000 and current mileage was approximately 81,000.
