What's wrong?
The drive belt pulley on these 2023-2026 Micro Bird G5 School Bus and Mb Ii School Bus vehicles is a grooved wheel that keeps an engine belt moving in the right path. On buses equipped with the extra air conditioning compressor kit, that belt also helps drive the added compressor. The nearby oil lines carry engine oil through the engine compartment, so they need clear space around moving pulleys and belts.
In the affected buses, the pulley was positioned incorrectly when the extra air conditioning compressor kit was installed. That places the pulley close enough to rub against the oil lines. As the engine runs, contact between the spinning pulley and the oil lines can wear through or damage those lines, which can lead to an oil leak and smoke from the engine compartment.
There is no warning sign before failure. Once the line is damaged, an owner or driver can notice smoke from the engine area, oil smell, or signs of leaking oil.

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?
A damaged oil line can leak oil. If leaking oil reaches an ignition source, fire risk increases. Schedule the recall repair as soon as Micro Bird makes the remedy available, and ask the dealer what to do if you see leakage before then. Repair will be free at any franchised Micro Bird dealer once available.
What should I do?
- Check your VIN to confirm your 2023-2026 Micro Bird G5 School Bus or Mb Ii School Bus is included in this recall.
- Watch for Micro Bird's owner letter, which is expected to be mailed June 29, 2026, because the final repair is still under development.
- Contact Micro Bird customer service at 819-477-2012 with questions, and reference recall number 26V287 (Micro Bird recall 26-121-OUS) when you call.
- Avoid carrying passengers if oil is leaking near the engine, and contact Micro Bird before moving the bus.
- Keep documentation from any inspection or repair related to the second air conditioning compressor drive belt pulley and oil lines.
What happens at the repair
Micro Bird is still developing the final remedy, so the dealer repair is not ready to schedule yet. Once the remedy is available, a Micro Bird technician will inspect the second air conditioning compressor kit area, including the drive belt pulley and nearby oil lines, and repair the vehicle under the recall. The final dealer repair will be free once available. If you already paid for a related repair, Micro Bird says owners can submit a claim through the recall portal listed in the owner notification. The reimbursement period is not limited in time.
