Hello everyone, this is my first post here but I have been on nissanclub for a while. I have been doing a little research into the big precat issue with the 02/03 2.5S engines. My dealer has now informed me that indeed that is my problem. LISTEN UP! If your 2.5S has less than 80k on it, the exhaust is manufacturer warrantied, by law. Since my car falls within those parameters NISSAN IS COVERING ENGINE REPLACEMENT. I don't have a manufacturers extended warranty, I do have an extended warranty through a warranty company but the service manager told me that they weren't even contacting them because Nissan found the flaw and is fixing it. Maybe they are finally actually owning up to their defective exhaust systems on those model engines. I don't want to count my chickens yet because even though the new engine is there, I don't have the car yet but I'm thinking it has to do with the fact that I made the service manager aware that I researched this problem and I let him view tons of material that supports this issue. In fact, some of that material that I found was here in nissanforums. Thanks to all

Hello! This sounds strange, but I'm thrilled to find that other people are having this exact same problem. I have been beside myself with worry over it. I am getting the runaround like crazy. Do you recommend going straight to the dealer to resolve? I've been dealing with an agent at Nissan North America, but getting nowhere. My agent says she's "working with the dealership." My challenge is that I'm around 88K and I bought my car at Carmax. What should I do now? My Carmax warranty won't touch it and they've referred me back to Nissan. But Nissan is saying they can't help b/c I didn't buy it there and I'm past the manuf warranty. What should I do now? Should I show up at the dealership with my evidence? Thanks for your help!

First I'd run your VIN with NNA and see if the pre-cat recall procedure was performed, if it was, find the number for the dealership that did it. Contact them and ask for the records and present that to NNA, dispute the fact that the recall work was done and the pre-cat still managed to ruin the engine. You may have a tougher fight being that the exhaust is over the 80k, but I've heard it can still be done....
The pre-cat issue is this, I'm trying to quote it as best as I can, saw it in numerous TSB's. At excessive heat and certain driving conditions, the materials in the pre-catalyst can deteriorate and sand-like particles can be sucked back into the engine, scoring the cylinder walls. This will increase oil consumption and/or coolant consumption which in turn will lower overall engine compression. If the owner continues to drive the vehicle under these conditions, the engine will need to be replaced.
Appreciate the information. Is there a forum link for a solid preventative maintenance / modification fix? I recall reading a spot on a Header Install with a brief spill on possible Emission Testing failure issues associated with it. I'd rather put a good legal fix on my '03 2.5L 77K miles pre-cat, than traverse the roads you have experienced.
Thanks.

I'd ALSO like to hear of a modification or fix!! Nissan should redesign the exhaust system OR buy our cars back! I've heard of factory Nissan replacement pre-cats causing the same exact problem!
well i had the same problems. fixed the headers and still nothing. i had to replace the engine at my expsne. any way nissan can either reimburse me or do something ? after all, there rep has gone down and i will never buy a nissan.
Hello. Do you have an update on this free repair? I am having the same issue with my 03 Altima - Dealer is not willing to replace ithe engine for free. Can you explain a bit more about what you had to do, say, demonstrate in order to get it replaced? I bought my car new. It now has 72,000, and I want to be able to convince the dealer and/or NNA to replace the engine for free beucase the Cat system is covered for 80K miles under federal law.
Research time for me! Any advise input you could offer would be awesome.
