Problem Description and Possible Solution
A weak or failing fuel pump can cause power loss due to lower fuel pressure and lean mixture conditions. This rarely causes a Check Engine Light to illuminate and should be repaired to avoid catalytic converter damage.

2006 Nissan Armada SE - both catalytic converters were replaced under warranty at 70,000. At around 80,00 shuddering, and unable to stay running, dying in motion, etc. took it to an independent mechanic, not dealership. He replaced fuel pump, but after test driving for a while he said the problem was still present. I don't know what he did to resolve it (something about a sensor maybe), but he returned my car running fine. However, the engine service soon light had come back on shortly afterward. A recent diagnostic for yearly inspection sticker showed both catalytic converters failing. Took it to Nissan - they said the fuel pump had damaged the catalytic converters and that all needed to be replaced ($2,200). They also said that the 02 sensors could potentially be "sucked in" and the engine would need to be replaced I took it back to the mechanic who installed the fuel pump, who said that Nissan was taking advantage of me, and that there was nothing wrong with the car. He turned off the engine service light and said he would get it inspected for me (suspicious? maybe has a friend in the business who will give him a sticker). I don't feel comfortable with his diagnosis, and don't know whether to trust Nissan service department either. I am afraid to drive it for fear of destroying the engine. A third opinion would probably be prudent at this point. Any advice would be appreciated.
Hesitation with a wide open throttle, then when you back off the throttle the truck speeds up.
We failed our emissions test for our Armada, we didn't fail the previous year. We have had our car leaking oil. The check engine light has been on. There has been problems with fuel....it'll show that I have less than half a tank when really I'm on empty. I just found out this is a problem that was reported as a recall back in 2010.
ON A TRIP FROM NY TO FLA ENGINE LOST POWER,STALLED. WENT TO DEALER AT FIRST DIFFICULT TO DIAGNOS, BUT TURNED OUT BAD FUEL PUMP, THEN KILLED CATALYTICS, CRACKED MANIFOLD. NOW NISSAN HAS A ECM RELAY RECALL.
Driving my family cross country form TX to CA, the check engine light came on. I took it to a mechanic and he said the code came back that something was wrong with #2 bank catalytic coverter. I told him my situation and he said I should be fine for the duration of my trip. Well, we made it to Phoenix before it got so bad that I could only do about 15 MPH and barely keep it running. I found a mechanic and $1400 later I had a new converter and I was back on the road.
I bought this Armada at the end of January 2015. It is now July 11, 2015. I have had my AC worked on twice, both O2 sensors have went out twice, changed the Catalytic converter and AGAIN my AC has gone out. I am so sick of this vehicle and HATE that I am spending a ton of money every month on a payment for a piece of crap!
The whole back console in my 2009 Nissan Armada fell down. Its almost $1000.00 to have it replaced. The guy at the dealership stated they comes because they are too heavy.
