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 4 cyl 2.5L

  • Manual transmission
  • 155,000 miles

Radiator Fans do not work at all, I think its the reason the plastic top on the radiator cracked, just replaced it today & runs a lot better with new radiator and runs cooler than the old one. I fear if they don't work radiator itself will get too hot therefore making the plastic on the top or bottom weaker by the mile.
