My 2014 with 64K miles just had the check engine light come on. Took it to the dealership and they said that two NOx sensors and the cat converter have gone bad and that it will be $4k to fix not under warranty. OUCH. Has anyone else had this issue? Seems awful early for this to be going bad.

Emissions equipment should be covered for 100K...I would inquire about that

DanD.

Does anyone know the real story about emission warranty? What does it cover? And what is the term? 8/80k or 10/100k
There is thread with AdBlue heater died, and sounds like MB doesn't care and its not covered.

REPLACED TWO NOX SENSORS AT 71K. IT'S A 2014 DELIVERED IN FEB OF 14. DID NOT REPLACE THE CONVERTER(S).
