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.

The contact owns a 2003 Nissan Sentra. While driving less than 10 mph, a loud popping noise was heard from the engine.

A large number of 2003 Nissan Sentra's are under recall for bad catalytic converter. I own a 2003 Nissan Sentra who's catalytic converter is bad, but am now told my specific VIN number is not covered by the recall. This is a serious emissions issue, and my car will now not pass the emissions test for state inspection. My vehicle should be added to the recall list. My check engine light has been on since 69000 miles, proof of which can be found in service records from southern states Nissan in raleigh, North Carolina. My vehicle was in their service center in Jan. Of 2006 to replace bad computer components. When my vehicle left the service center, the check engine light was still on. A diagnostic test showed the cause to be catalytic converter failure.

Sentra 4-cyl

  • Automatic transmission
  • 29,000 miles
I bought my car in may of 2004. Since then, the interior dash lights, tail lights and various fuses have blown at least 3 times each. Lights were replaced. The dealership said there was nothing wrong that they could find, and they had replaced the fuses. The very next day, the same fuses blew again. The dealership said there were no "open recalls" on my car. It is a 2003 Nissan Sentra SE-R. the catalytic converter failed at approximately 29000 miles. This actually blew my engine, which dealership relaced. The fuse problem is still persistent.
