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.

The contact owns a 2003 Nissan Altima. While driving at speeds of 35 mph, the engine would not respond when depressing the accelerator pedal. Within a few moments after sitting idle, the vehicle became responsive to the depressed accelerator pedal. The vehicle was taken to the dealer where a diagnostic test was performed, however the failure could not be duplicated. The vehicle was taken to a second dealer but they too, could not duplicate the failure. The failure mileage was 94,364 and the current mileage was unknown.

While driving on the highway and when pushing on the gas pedal vehicle would not accelerate, and it does this when trying to precede on from a stop light. It might go 2-3 mph. This first started happening around September 1, 2004 and this happened intermittently. There was no fore warning and there was no noise.
