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.

My aaa light duty mechanic diagnosed my 2003 Nissan Pathfinder with a cracked catalytic converter. He told me it should be covered under warranty and under 8 years, 80,000 miles emissions law. I took the car in and asked, they told me it wasn't because it was actually the tubes and charged me $700 not including labor to replace. Seems like the tubes should be covered under the same act since the cat converter can't function properly without the proper tubing. I think this dealership failed to comply with the warranty agreement and from the overwhelming number of similar complaints I've found, I believe Nissan has shown no accountability to fix the issue.

Pathfinder 4WD 6-cyl Diesel

  • Automatic transmission
  • 47,269 miles
The contact owns a 2003 Nissan Pathfinder. The contact heard a loud sound coming from underneath the front driver side of the vehicle. The sound was apparent from the exhaust pipes, especially when the accelerator pedal was depressed. She took the vehicle to the Nissan dealer and they stated that the resonator and catalytic converter caused the vehicle to leak exhaust fumes. The dealer offered to repair the vehicle, for a service charge, using a repair kit. The vehicle has not been repaired because it was not covered under warranty. The contact has not yet notified the manufacturer. The failure mileage was 47,269 and current mileage wa 54,400.

Pathfinder 4WD 6-cyl

  • Automatic transmission
  • 49,000 miles
Cataylitc converter cracked, six to eight inches along welded seem with less than 50K miles. Two seperate Nissan dealers have recommended repairing the catalytic converter, with part #20711-5W90A, a band and sealant kit, at customer's expense, denying the defect in workmanship is covered under the federal emissions 8/80 warranty. Both dealers state that the crack does not effect emissions.
