What's wrong?
The drag link assembly on the 2019-2021 Blue Bird Vision School Bus, Vision, and Vision Transit Bus is part of the steering linkage. It connects steering movement from the steering gear to the steering arm, so the front wheels turn when the driver turns the wheel. The castle nut and cotter pin hold that connection tight.
On affected buses, the castle nut at the drag link to steering arm connection was not tightened to Blue Bird's factory specification during assembly. A loose nut lets the joint move more than it should. That movement can allow the drag link to separate from the steering arm. If that happens, the driver loses steering control.
Blue Bird says issues on buses already in service should be found during the required CDL pre-trip inspection. Look for looseness or movement at the drag link connection before the bus is driven.

What's the safety risk?
If the drag link separates, steering control can be lost, increasing the risk of a crash. Treat loose or questionable drag link connection points found during the required pre-trip inspection as a reason to keep the bus out of service and call the dealer. Repair is free at any franchised Blue Bird dealer.
What should I do?
- Check your VIN to confirm your 2019-2021 Blue Bird Vision School Bus, Vision, or Vision Transit Bus is included in this recall.
- Contact a franchised Blue Bird dealer to schedule the free drag-link connection inspection and tightening that secures the steering linkage.
- Bring the recall notice if Blue Bird mailed one. If not, reference recall number 20V356 and Blue Bird recall R20AW-SB when you call.
- Drive cautiously until the inspection is complete. If the steering feels loose or abnormal, stop using the bus and contact Blue Bird customer service.
What happens at the repair
At the dealer, a Blue Bird technician inspects the steering drag link assembly connection points, including the castle nuts that attach the drag link to the steering arm. Any loose connection points are tightened as needed. The inspection and any required tightening are free under the recall. Blue Bird's general reimbursement plan is on file for owners who already paid for the same repair. Keep repair invoices and payment records, and contact Blue Bird customer service or the dealer service desk for the claim process.
