What's wrong?
The inside panels under the windows on 2021-2022 Micro Bird G5 School Bus, T-Series School Bus, and Mb Ii School Bus models are part of the bus body structure. They sit below the window opening and are supposed to be bonded to the windowsill so the body joints hold together as designed. That bond matters because school bus body joint strength depends on panels staying attached under load.
On affected buses, the panel bond was not strong enough. Micro Bird traced the problem to too little glue, or too much time between applying the glue and installing the panel. During inspection, a small gap was found between the inside panel and the windowsill. Testing showed that at least some buses with this condition did not meet the school bus body joint strength standard.
There is no warning sign before failure. Drivers and operators are not expected to hear, feel, or see a driving symptom before the panel attachment problem is found during inspection.

A matching year and school bus model does not confirm inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Insufficiently attached panels can separate during a crash. That raises injury risk for occupants without creating a normal driving warning sign before the crash event. If your VIN is included, arrange the correction and follow the dealer's parts instructions before the bus returns to regular service. Repair is free at any franchised Micro Bird dealer.
What should I do?
- Check your VIN to confirm your 2021-2022 Micro Bird G5 School Bus, T-Series School Bus, or Mb Ii School Bus is included in this recall.
- Contact a franchised Micro Bird dealer to schedule the free body-panel attachment repair that secures the inside panels under the windows.

- Call Micro Bird customer service at 1-819-477-2012 with questions and reference Micro Bird recall 22-094-PUS.
- Ask the dealer whether the bus can stay in service before the repair, especially if the inside panels under the windows look loose.
What happens at the repair
At the dealer, a Micro Bird technician provides the recall parts and instructions, then corrects the inside panel attachment defect under the windows.
