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.

CarComplaints.com 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.

My 2003 Nissan started having a misfire problem in July/August of 2011. It would miss and lose power especially going up hills. Took it to a mechanic and he changed the crank senor. Ran great for awhile, starting missing again took it back to him and he checked the coils and changed the spark plugs and added a bottle of cataclean to clean the converter. Ran super for awhile and started to miss again. All during this time still getting Code 302 Cylinder #2 misfire. Swapped coil 2&3 cleared code and still get Code 203 so it was not the coil. Took to mechanic and he cleaned the injectors. Started to miss again had a cylinder compression test done, vacuum test and checked for a intake leak. Had fuel injector on #2 changed still missing. Took to Nissan dealership they confirmed problem was not spark plugs or coils. Swapped engine computer no change. Changed crank sensor connection it was broken no change. Swapped fuel injector #2 and #3 still missing. Performed Top Engine Clean possible carbon build up still missing. Techs believes that Valve is sticking and the next step would be to remove Head and pull valves. I have spent around $570.00 dollars and now they tell me it would be $1,300.00 to pull the values and have them cleaned. I said forget it I will trade it in but not for another Nissan. Never again. Anybody have any ideas what it could be causing the misfire and is there a easier fix then pulling the valves? HELP HELP HELP
