What's wrong?
The 2012-2014 Ic Bus Ce and Casb school buses in this recall use an Eaton hybrid automated transmission. The transmission chooses gears and coordinates engine speed while the bus accelerates, slows, and downshifts. In normal operation, the software should match the gear change to the driver's pedal input so the bus responds predictably.
On affected buses, the transmission control software can raise engine speed during a downshift even when the driver has not asked for more power. A downshift moves the transmission into a lower gear. If the software adds engine speed at that moment, the bus can surge instead of continuing to slow in the way the driver expects.
There is no warning sign before failure. The driver notices the issue only when the transmission downshifts and the engine speed rises without driver input.
Who's affected?
The scope spans Ce and Casb buses across the 2012, 2013, and 2014 model years, all tied to the automatic transmission.

| Units affected | 22 |
A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
An increase in engine speed can cause unintended acceleration and increase the risk of a crash. If the bus accelerates unexpectedly, keep firm brake pressure, steer to a safe place, and schedule the recall work soon. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2012-2014 Ic Bus Ce or Casb is included in this recall.
- Confirm with Ic Bus customer service whether the free Eaton hybrid control module software update is open for your bus.
- Contact a franchised Ic Bus dealer or Eaton authorized service facility for the software update that corrects transmission software that can raise engine speed during downshifts without driver input.
- Reference recall number 14V043 when you call.
- Drive cautiously until the update is complete, and report any unintended acceleration concern to the dealer before the appointment.
