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. Notes: Here's a disturbing trend for the 2002 Nissan Altima: the engine starts burning oil like crazy, the catalytic converter goes bad, the head gasket blows and eventually the entire engine needs replacement. Sound familiar? Like a script from a horror film, these Altimas seem doomed to fail around 95k miles.

Both the driver side and passenger side floorboards are heavily rotting out. The passenger side seat is even moving.

I took my car in for an oil change and my mechanic indicated that I had a rusty driver's side floor board. He said that he was able to stick his hand through the bottom of my floorboard and touch my driver's seat. This had me very concerned due to the potential for the driver's seat to fall out of the car while I'm driving. My mechanic indicated that he's had the same problem with at least 2 other Nissan Altima. Based upon the number of complaints, it looks like this is a known issue and that Nissan will not do anything to compensate. It cost me $550 to fix due to the extent of the rust.

Altima 6-cyl

  • Manual transmission
  • 122,000 miles
The contact owns a 2003 Nissan Altima. While driving 45 mph, the driver's seat collapsed on the right side. The failure moved the contact's body to one side of the seat. He noticed that the metal fatigue in the back bolt, which held the seat to the bottom, was snapped into two parts. The vehicle has not been diagnosed by the dealer. The contact plans to have the failure corrected at a welding shop. The current mileage was 124,394 and failure mileage was 122,000. Updated 07/15/08. Updated 07/15/08

While driving at 20 mph driver's seat started to bend toward the back right of the vehicle. As time went by the seat began to bend more and more. Currently, not only is the seat twisted but, there is a metal bar protruding from the seat into the consumer's back.
