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.

2004 Nissan Altima with a recall for the intake manifold. Consumer states that he did not receive the recall notice. His vehicle began shaking violently and the check engine light illuminated due to the defect of the intake manifold. The consumer took the vehicle to his mechanic, who discovered that the flap from the intake manifold had worked its way loose and fallen inside the engine. The flap was unable to be re-attached independently and the entire intake manifold had to be replaced.

2004 Nissan Altima 2.5 had severe missing issue and dealer advised that it was an issue with the screws of the power ring on the intake manifold. The screw had came loose and damaged the intake manifold. Nissan has voluntary service campaign qr25de power valve ( P5202) for this issue. My car has the exact issue and the year and engine size is the same. The VIN number of my car is within the posted VIN's of this campaign - however they now say the "campaign" is VIN specific, and you guessed it - my VIN isn't on their list. $700 later the dealer won't pay, Nissan America refuses to honor the fix listed in their own campaign this is a known design flaw issue, same car, same engine size, within the VIN numbers listed. No relief. They also replaced all the screws with "upgraded screws" and lock each screw. The internet is filled with this issue and others with no assistance. Please make this a recall !
