What's wrong?
The service door emergency release on 2003-2022 Micro Bird G5 Transit Bus, Mb Ii Transit Bus, and T-Series Transit Bus models is the backup release for the bus entry door. It is meant to let an occupant or responder open the service door when the electric door system does not open it in the normal way. The handle has to move the release parts cleanly so the door panels can open.
On affected buses, the electric door is out of adjustment. That allows the door mechanism to shift out of alignment, which puts the release handle in a bind instead of letting it move through its full travel. When the handle binds, the door panels can stay closed even when someone operates the emergency release. Micro Bird found that the issue can involve the exterior handle, the interior handle, or both.
There is no warning sign before failure. The problem shows up when the emergency release handle is needed and the door does not open as intended.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
If the service door does not open during an emergency, passengers have fewer exit options and evacuation is delayed, increasing the risk of injury. Keep the door adjusted as instructed and schedule the recall repair soon if your VIN is included. Repair is free at any franchised Micro Bird dealer.
What should I do?
- Check your VIN to confirm your 2003-2022 Micro Bird G5 Transit Bus, Mb Ii Transit Bus, or T-Series Transit Bus is included in this recall.
- Contact a franchised Micro Bird dealer to schedule the free service-door adjustment that fixes the binding emergency release handle.
- Bring the recall notice if you have it. If not, reference recall number 21V531 when you call.
- Avoid using the bus for passenger trips until the service door opens correctly and the adjustment is complete.
- Call Micro Bird customer service at 1-819-477-2012 with questions about the repair.
What happens at the repair
At the dealer, a Micro Bird technician uses the recall instructions to correctly adjust the service door. The goal is to keep the emergency release handle from binding so the door panels open when the release is used. The adjustment is free under the recall, and required parts are covered. If you already paid for this repair, Micro Bird says repair costs are reimbursable. Bring your repair paperwork to the local dealer and ask the service desk to process it under recall 21V531.
