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 Frontier Owner Comments

problem #2

Jul 012009

Frontier 6-cyl

  • 39,000 miles


2009 started hearing knocking noise from engine. Seem to come and go. Took it to Nissan and discovered the crank pulley was coming apart. Year and half later belts were squealing. Took truck in for tires and asked them to check the belts.discovered the idler pulley was coming apart. Was informed by service people at tire dealer( tires plus) they have seen this before on Nissan vehicles with the same engine. This was in 2011. Two bad pulleys with less than 42,000 miles on truck. No telling what would have happened if either of this pulleys had come apart at highway speeds. Have never heard of pulleys coming apart on a vehicle before.
