Either none have been filed with NHTSA, or this vehicle is too new for reports to have accumulated.
Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
SERVICE BRAKES
The mechanical brake switch & bracket design has a potential for cumulative at-limit stack up clearances to exceed the limitations of the mechanical switch. As a result, a preventative maintenance adjustment procedure is necessary and, at times, settings can be difficult to achieve.
ENGINE
The 7.3L radiator uses adapter nuts, if not properly sealed, exposes the opportunity for fluid migration through threads. Primary failure seen is deterioration of the EPDM gasket sealing the transmission oil cooler (TOC) to lower radiator tank, which allows a path for coolant to leak externally. Secondary failure seen is cross contamination between coolant and transmission oil. To eliminate the possibility of experiencing this condition, Blue Bird is providing 1 year of coverage to update the transmission oil cooler interface along with a visual inspection of any cross contamination at time of completing the interface update. Please follow the flowchart within the instructions to determine if any additional repair activity is necessary and, if so, complete further repair procedures as stated.
ENGINE AND ENGINE COOLING; POWER TRAIN
Revised: Coolant leaks at the transmission cooler fittings on the radiator are occurring due to deformation of the gasket used to seal off the transmission cooler. This deformation is caused from transmission oil wicking through the thread adapter threads and exposing the lower portion of the gasket to transmission oil. Re-configure hydraulic interface between the transmission cooler lines and the transmission oil cooler. SU2302 Revised to include Labor Time of 1 Hour and a Component Code.

Cummins recently issued Temporary Repair Practice (TRP2484) for certain vehicles with DEF sensor failures in which DEF sensor replacement parts are not available. This provides a temporary ECM calibration that inhibits engine warning messages for communication errors with the DEF sensor allowing continued operation without engine derate. Regulators are allowing for this temporary calibration to be loaded in the engine ECM by a Cummins authorized repair location if the DEF sensor fails. This temporary calibration does not repair the failure therefore a final repair must be performed and the original calibration be re-installed. Field Service has been requesting an ECM image be uploaded within the support ticket as part of the diagnostics and is carried over into Service Update 2201 (SU2201). In order to receive an authorization code and utilize Cummins TRP2484, you must follow the process, as outlined in SU2201. The specific component affected is Assembly Code: 35-300 Emissions Components.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
