After a decel to 20ish mph, the automated manual transmission attempted to shift into gear to begin acceleration. The transmission made load noises indicating a failure followed by a transmission warning with the fault code being 617 FMI 14. All acceleration and engine braking ability was disabled, increasing the risk of an accident due to the vehicle being disabled. A similar safety recall for the same vehicle would be NHTSA #24V-190 which causes the vehicle to become disabled and increase a crash risk. This is a known issue caused by compressed air contamination according to Eaton Transmissions service bulletin TAIB-1006, which was first published April 2023. In the over 3 years since the service bulletin was released, Eaton, Peterbilt, Paccar, and Cummins(engine manufacturers) have failed to develop adjusted maintenance intervals, added inspections, or additional filtration to prevent contamination of the transmissions air system. They've instead passed the financial burden of repair on the customers by denying warranties. The dealer determined based on TAIB-1006 that the MTM requires replacement and the air system cleaned of contamination. This was based on data and not a detailed inspection to determine the internal failure.

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.
