Report: Check Engine Light Due to Failure of Catalytic Converter Closest to Cylinder Head
Nissan Altima Problem
Exhaust & Emissions Affected: 2.5L 4 Cylinder
Average Mileage: 110,532 mi (13,000 mi - 185,000 mi)
The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.

Service Engine Soon light came on. Took to AutoZone for diagnostic. P0420 error. Currently seeking estimates for repair.
Just replaced the catalytic converter after replacing the coil packs first. Now the car fails to heat during idol. I hate Nissans!
Problem started earlier. Trouble codes 0420 and 011 detected. Also oil leak at valve cover. Took to Gunn Nissan for repairs. The oil leak caused leakage/damage to two of the spark plugs. New cat, valve cover, wire, timing belt 2186.00. Ouch!!

Was out and came home. Stopped the car and went in to the house. 10 min later I came out got in the car and tried to start it. It turned for about a second the there was a high squeal. I had the car towed to Nissan who said after a scan that the Engine had no oil and the fault was the catalytic converter. It never gave me an indication it was going to fail. My engine temperature stayed at the normal operating temperature. My only options right now are an engine and catalytic converter replacement. I wrote a complaint to Nissan and they came back and said they would not repair the damage. I often wonder with the first on (Northside Nissa) and the tires for life program they sponsored and then went out of business, isn't this lifetime warranty on the drive train a scam and they too will fold up their tent and leave when all these tires come due. Needless to say I'm very upset with their decision.

Check engine light came on and tested to find the Catalytic Convertor at the Manifold failed along with Oxygen Sensor.
Check engine light came on and the dealership said it needs a new catalytic converter and since it took them 5 months to diagnose the problem they now believe the particals were sucked into the engine and that needs to be replaced.
