this is not a recall, but an extended warranty item
also the coverage is extended to 80,000 miles/8 years (not 5 yrs)

my bad i didnt type exactly what it said. but yeah you are right that what it is. and not what i had originally stated.

Ok, glad I stumbled on this discussion.

I just had the ECM recall done on Monday. Then 3 days later my Pathfinder threw a code for the catalytic converter in bank 2 being bad. Seems very coincidental and now the dealer wants to charge me $1200 + labor. Can anyone advise if the ECM work could cause this Catalytic Converter code? I read all of the posts and someone did mention replacing the IPDM (not sure what that is yet) fixed the issue and that it was an erroneous code.

Info:

2005 Pathfinder, 87,000 miles.

About a year ago my IPDM and cat 2 went out. I had to pay around $1,600 to fix both of those. Approximately 3 months later cat 1 went out. That was another $1,100 repair. The dealership was able to get Nissan to cover $700 of it, so I only ended up paying $400. I considered myself lucky and didn't press the issue. And of course this all happened after my 100k warranty went out.

I guess I just wanted to let everyone else know that there's another Nissan customer who paid through the nose to get the IPDM / catalytic converter repair. I got the recall notice today about the ECM. And, we've had the issue where the a/c blows only cold air when the heater is on and the car is just idling.

My wife and I are in the process of buying a new car and just want to cut our losses. It has over 153,000 miles.

Ok there is definitely a pattern here. Vehicle was stalling so I had the dealer do the ECM relay. Still was stalling so I swapped out the IPDM believing it was fried. Then my fuel pump goes out and now my bank 2 cat is bad code P0430. All within a week of each other. This vehicle is turning into a nightmare. I guess my next step is to fix the cat, but what is causing this bad chain reaction of events here? Anyone get this solved or do they just get frustrated and get rid of them???

Citcope the Honda pilot also has its own issues. the biggest issue is with the ac. do your research before you take the plunge. i work for Honda and almost bought one. my path as 113k with few issues. knock on wood. i drive it all over the place and without a second thought.

My guess is that there was nothing wrong with the ECM relay or IPDM and the problem was the fuel pump all along, which was probably causing a lean condition and the stalling and "possibly" damaged the catalytic converter. The original reason why IPDM's were replaced in early R51's was because Nissan said the ECM relay was not replaceable, which wasn't true. When people started using $10 aftermarket relays in place of the ECM relay rather than replace the IPDM, Nissan suddenly deemed the relay "serviceable" and now you can get the relays for just a few dollars. When the relays failed, it wasn't that the vehicles just simply stalled out, but would surge violently and dash lights would flash on-and-off and cut off. While it is possible for an IPDM to fail, by your own words you never properly diagnosed it as being bad and replaced it because "thought it was fried." As far as the catalytic converter, it's impossible to say at this point whether it failed because of the fuel pump issue or not, because many converters on these vehicles have simply become inefficient at breaking down the emissions, which is what usually causes the P0420/P0430 trouble codes. That said, an improperly running engine is never a good thing for a catalytic converter.

Thankyou smj999smj and jahblessings. Smj999 would you mind reading my other thread in the misc sect about the fuel pump? I would be very relieved if the fuel pump was all it was. I agree the vehicle never got diagnosed properly, but in my defense I was on a road trip and every time I was at a dealer the condition could not be repeated, and there were no check engine lights. Could they have done anything more diagnostically with no CEL?

They could have used a fuel pressure gauge to test the fuel pressure and see if it was within factory specs.
