What's wrong?
The wheelchair lift on affected 2012-2018 Collins School Bus vehicles is adaptive mobility equipment that raises and lowers a passenger between the ground and the bus floor. These buses use Ricon S-Series and K-Series Titanium wheelchair lifts, including K200, K201, K550, K551, S200, S201, S550, and S551 units. The lift relies on positioning inputs to know where the platform is during travel and to stop at the correct floor height.
The problem is in the positioning input cam, a part that helps tell the lift where the platform is. If that cam fails while the lift is in use, the platform can continue past the vehicle floor height instead of stopping level with the bus floor. That leaves the passenger and wheelchair on a platform that is no longer aligned with the doorway.
There is no warning sign before failure. Treat any uneven platform height or lift movement that does not stop where expected as a service issue, and keep the lift out of use until it is inspected.
Who's affected?
The scope spans seven model years, all tied to the adaptive/mobility equipment component.

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 wheelchair lift platform stops above the vehicle floor, a wheelchair user can tip inward toward the vehicle while exiting, increasing injury risk. If the lift does not sit level with the floor, stop the transfer and call the dealer before using it again. Repair will be free at any franchised Collins dealer once available.
What should I do?
- Check your VIN to confirm your 2012-2018 Collins School Bus is included in this recall.
- Wait for Collins repair instructions or contact Collins customer service before scheduling service, because the remedy is listed as under development.
- Ask Collins about the free Ricon wheelchair-lift cam replacement that fixes the lift platform rising above the bus floor.
- Bring the Collins owner notice if you have it. If not, reference recall number 18V584 when you call.
- Keep riders clear of the wheelchair lift until Collins or the servicing dealer confirms the cam replacement is complete.
What happens at the repair
Because this remedy is still listed as under development, do not assume the final dealer repair can be scheduled now. Once Collins opens the final repair, the dealer will replace the wheelchair lift's injection molded cam with an aluminum machined cam. Parts and labor will be free under the recall. Collins has a general reimbursement plan on file for owners who already paid for the same repair. Keep repair orders and payment documentation, then contact Collins customer service or the dealer service desk about submitting a claim.
