Published May 25, 2026

Recall 18V574 covers 6 2012-2018 Micro Bird school buses for a wheelchair-lift cam defect. Repair is free at a Micro Bird dealer.

Micro Bird is recalling 6 2012-2018 G5 School Bus, Mb Ii School Bus, and T-Series School Bus vehicles because certain Titanium wheelchair lift cams can fail while the lift is in use. If the platform travels above the bus floor, the wheelchair user can tip inward toward the vehicle, increasing injury risk; Micro Bird dealers will complete the recall repair free of charge.

What's wrong?

The wheelchair lift on the 2012-2018 Micro Bird T-Series School Bus, G5 School Bus, and Mb Ii School Bus raises and lowers a wheelchair platform between the ground and the bus floor. A positioning input cam is part of that lift system. Its job is to tell the lift where the platform is so the platform stops level with the vehicle floor.

On the affected Ricon S Series and K Series Titanium lifts, that cam can fail while the lift is in use. When the lift loses the correct position input, the platform can travel higher than the bus floor instead of stopping at the proper height. That creates an uneven transfer point for a wheelchair user and means the lift system does not meet the platform lift safety standard cited in recall 18V574.

There is no warning sign before failure. A driver, attendant, or passenger will not have a reliable symptom that shows the cam is about to fail before the lift is used.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included in this recall.

What's the safety risk?

If the lift platform stops above the vehicle floor, a wheelchair user can tip inward toward the vehicle while exiting, increasing the risk of injury. Use the lift only after confirming the platform is level with the vehicle floor, and stop if it does not settle correctly. Repair is free at any franchised Micro Bird dealer.

What should I do?

  1. Check your VIN to confirm your 2012-2018 Micro Bird T-Series School Bus, G5 School Bus, or Mb Ii School Bus is included in this recall.
  2. Contact Micro Bird customer service at 1-819-477-2012 to schedule the free wheelchair-lift cam replacement through a Ricon dealer.
  3. Reference recall number 18V574 and Micro Bird recall 18-077-RUS when you call.
  4. Bring the recall notice if Micro Bird mailed one to the bus owner or operator.
  5. Avoid using the wheelchair lift for boarding or exiting until the cam replacement is complete; arrange another accessible vehicle when lift access is needed.

What happens at the repair

At the dealer, a Micro Bird technician replaces the wheelchair lift's injection molded positioning input cam with a new machined aluminum cam. The work addresses the cam that controls lift positioning, so the platform stops at the correct floor height during use. Parts and labor are covered under the recall because the remedy is available. Ask the service desk to confirm the lift model and recall 18V574 when you schedule the appointment.
