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.

2003 Nissan 350Z Owner Comments

problem #4

350Z 6-cyl

  • Automatic transmission
  • 73,000 miles


Bought a 2003 Nissan 350Z used from keyes Nissan of woodland hills, ca. Tiptronic (auto/semi-manual) transmission needed to be replaced within 45 days. Now a whining noise that is still not fixed as well as excessive heat from shifter area that causes passengers to sweat & scalding hot to touch. Car hasn't seemed to run right since. Seems every 350Z owner has the same atypical problems-tire feathering, transmissions replaced, rear axles, power window motors fail(the last 2 are my next trip to the dealer). Nissan needs to fix our nightmare. Nissan support is nonexistent as well, which makes your ordeal all the more miserable.

Consumer owned a Nissan 350Z track version 2003. He took vehicle to dealer for recall repair about a year ago. Consumer stated it was a recall, however, could not find recall on NHTSA web site. Ntb03-046 was the number identifying the recall that consumer had. Repair work was done on 6-11-04. Then, on July 19, 2005 consumer took vehicle to gardena Nissan in California, and they told him that the problem involved front tires wearing out on the inside during repair work they replaced the right front compression rod. Consumer contacted Nissan, and they told him that after recall and warranty repair work was only good for 10,000 miles. Consumer believed that recall repairs did not fix problem, per gardena Nissan. Six months after consumer bought vehicle when shifting up or down at any speed periodically it will not go into gear. Nissan was aware of the situation, and they did not want to do anything about it.

While driving automatic transmission doesn't shift properly from the third to the second gear. Dealer inspected vehicle several times, and was not to duplicate but not correct the problem. Consumer began to notice inability to engage 2nd gear from 4th, and 3rd gear to 2nd regardless of the speed of the vehicle. It sometimes take consumer two or three attempts to engage transmission properly.
