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.

Altima SL 2.5L V4

  • Automatic transmission
  • 152,000 miles

I just bought a used Altima 2003. The heater works fine (for now anyways), but when I start the heater on, say 1st level of airflow, it produces an annoying rattling noise below the glove box, but not glove box itself. I looked everywhere, tried pushing on the glove box but it doesn't change anything. I concluded that it seems like / sounds like some kind of fan near the front passenger's legroom. Very annoying!!! Stupid Nissan. Can't make normal cars.
