The technician's computer showed the following result:
MED177-N3/10 Motor electronics "MED177" for combustion engine "M278" (ME)
P042000 - The efficiency of the catalytic converter (cylinder bank 1) is insufficient
technican said there was a problem with the Right side Catalystic Converter efficiency "caused by metals in catalytic converter depleting, allowing it to not clear exhaust fumes."
Is this something I need to worry about? or are they just trying to fleece me? Seems kind of wrong to need to replace a catalytic converter when my car only has 22,000 miles (2015 model purchased in 2014 - so just outside the 8 year warranty on exhaust) Thanks in advance for any advice.

The cost of cats depends on the state that you live in. I live in California and we have the WORST of prices for replacement Cats. I have replaced cats on my older cars and I could have installed a $600 one for a 05' Nissan XTerra but for CARB (California Air Resource Board) I had to pay $1500. I would assume the $1500 quoted above wouldn't work in every state.

Years ago someone told me there are different price points for cats ... the OEM-grade product is designed to last for the 8/80 emission warranty period and costs more.
"Replacement" cats have less precious metal and aren't made to last as long and therefore sell for less.
