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 Sentra Owner Comments

  • 69,000 miles


In my 2004 Nissan Sentra SE-R spec V with a 2.5L engine/manual transmission, at about 69K miles the car suddenly experienced unstable engine idling and significant power loss. First mechanic found loose metal pieces in the intake manifold area, along with spark plug one fouled. Metal pieces were removed and a new spark plug was installed. Car ran okay for a few weeks, the same symptoms occurred. Mechanic removed intake manifold and found two power valves and their screws obliterated and scattered throughout the compartment in dozens of loose pieces. Metal pieces removed, power valves replaced, screws replaced and secured with lock-tite. Symptoms occurred for a third time recently. I went to the Nissan dealership and spoke to the service advisors; they ran the VIN and found a recall on 04 Sentra 2.5L engine vehicles, specifically the power valve screws coming loose, causing unstable engine idling and power loss.
