Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

As Per Cummins: Our records indicate there is a Product Improvement Software Calibration Campaign (C2191) for the Cummins B6.7 CM2350 Model Year 2017 to 2018 engine(s) that you own or have purchased. Please refer to the attached table for engines that may be affected.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
