When the compressor fails, system air pressure drops, resulting in automatic application of the brakes. Unlike a conventional combustion-engine drivetrain, the all-electric drivetrain can continue producing sufficient torque to allow the driver to power through the automatically applied brakes, particularly when the low-air condition occurs while the bus is in motion.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
