There is an issue with the braking systems on the Bluebird buses which cause the brake lights to illuminate constantly, fail to illuminate, limit acceleration, and/or receive a "loss of brake input" warning message on the dash cluster. We have 43 Buses of like Year Models ranging from 2021 - 2022 Bluebird, Vision, that we have documented 38 separate repairs for 28 buses in our fleet related to the braking system. The brake pedal experiences excessive back travel that causes damage to the brake switch (part number 10026469). The cause of the excessive back travel is a gap between the pedal stop, rubber bumper, and switch mounting bracket. There is not enough adjustment area in the switch mounting bracket to prevent the excessive brake pedal back travel. Once the brake switch becomes damaged multiple issues become possible. There is potential for constant brake light illumination, no brake light illumination, a loss of brake input warning message, and sudden stopping of vehicle acceleration. The brake light illumination is not found consistently during the pre-trip inspection process due to the usage of the pre-trip lighting sequence button that provides false confidence that the brake lights are working properly. What component or system failed or malfunctioned, and is it available for inspection upon request? The brake switch failed parts are being returned to Bluebird for Warranty parts replacement. How was your safety or the safety of others put at risk? The multiple symptoms listed above produce various safety issues for the buses and other vehicles on the road. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, Multiple vehicles have experienced the same issue and the switches are being replaced as a repair. Multiple vehicles have reoccurring issues with the replaced switches. The local dealer has gone to the manufacturing facility and addressed the issue them.

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.
Suspect Population: Certain 2021 through 2026 Blue Bird BBCV buses, equipped with a 217” WB flat floor & Ford 7.3L powered engine. Condition:Chassis web fractures in or around the vicinity of the LF shock mount Root Cause Identification and Justification: • FEA modeling shows elevated regions of stress in proximity of the upper fastener hole for the LH shock mount resulting from several external influences. The highest stress stemming from shock extension forces in curb hop scenarios. • Bearing in mind the absence of this failure mode on standard floor chassis designs with substantially higher usage, the projected stress in this region of 4582 PSI is used as an objective bench mark of the acceptable upper limit. • Two corrective solutions are being executed as pragmatic countermeasures to correct this failure mode, based on the severity and frequency of the crack, if present. Repair plate 1 being the latest evolution. FEA analysis & ref chart below • Installation of this repair plate decreases the stress in this region to less than the standard floor chassis baseline allowing us to predict this solution to last the expected life of the chassis.

ENGINE AND ENGINE COOLING
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.

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.
