    On August 1, 2018, Cummins initiated a recall of the Selective Catalytic Reduction (SCR) unit catalysts in their 2010 to 2015 model year medium and heavy-duty engines. This recall affects over 500,000 heavy-duty vehicles nationwide. Customer letters for the first phase of the recall were sent to vehicle owners by Cummins starting August 1. Vehicles are to be brought to a Cummins certified service location for replacement catalysts and/or software upgrades. For assistance, including locating your nearest Cummins certified service location or determining whether your engine is covered by the recall, please contact Cummins Care on the web at https://care.cummins.com or call Cummins at 1-800-CUMMINS (1-800-286-6467).
    � Cummins will reimburse cost of previously replaced catalyst.
    � California Department of Motor Vehicles may require the completion of emission campaign repairs prior to vehicle registration renewal.
    � Cummins will phase-in recalls over time due to the large number of engine families involved. Some recalls will take effect in 2019 as
    shown in the table below. The table will be updated, as new engine families are included in the recall campaign.
    � For 2010-2012 model year ISX 15 Engine Families ACEXH0912XAP, BCEXH0912XAP, and CCEXH0912XAP, SCR replacement will occur
    when the SCR catalyst fails (triggers applicable engine lights/fault codes) within useful life beginning Aug. 1, 2018. Customer letters for
    these three engine families only will not be mailed out.
    � If your engine family is not listed below and you replaced your catalyst or if you have additional questions, please contact the ARB
    helpline at 1-800-242-4450.

    Possible something going on with fuel system for regen or engine is putting out to much nox or maybe even a bad nox sensor not very likely I. Last one being that bad sensor will kit cause long regens
