What's wrong?
The Liquid Spring suspension kit on the 2014 Horton Ambulance 623, 457, 403, 603, and 453 ambulances uses a fluid tank mounted to the frame. That tank is part of the suspension setup, which helps manage the vehicle's ride height and body movement while the ambulance is loaded and moving. The mounting bracket is the hardware that keeps that tank fixed to the frame.
On affected ambulances, the bracket that attaches the suspension fluid tank to the frame can fail. When that happens, the tank is no longer held in place and can separate from the vehicle. The filing does not identify a separate root cause beyond the bracket failure, so the important point for an owner or fleet manager is the bracket and tank attachment.
There is no warning sign before failure. Because the tank can separate without an earlier symptom, use the VIN check and dealer inspection to confirm whether this ambulance is included.

What's the safety risk?
A fractured suspension fluid tank mount can let the tank separate from the chassis. If that happens, the tank becomes a road hazard and increases crash risk for other drivers and the ambulance crew. Schedule the recall repair soon. Repair will be free at any franchised Horton Ambulance dealer once available.
What should I do?
- Check your VIN to confirm your 2014 Horton Ambulance model 623, 457, 403, 603, or 453 is included in this recall.
- Check for the owner notice from Horton Ambulance; letters were mailed on October 22, 2014.
- Contact a franchised Horton Ambulance dealer to ask about the free redesigned suspension-fluid-tank bracket repair.
- Reference recall number 14V558 when you call, and mention the Liquid Spring suspension fluid tank bracket.
- Avoid service use until a dealer confirms the suspension fluid tank bracket is secure or the redesigned bracket repair is complete.
What happens at the repair
At the dealer, a Horton Ambulance technician installs a redesigned bracket for the Liquid Spring suspension fluid tank. The bracket secures the tank to the frame, so the repair focuses on keeping that tank attached to the ambulance. The filing says owner notification began in October 2014 and the bracket installation is free of charge. Because the remedy status for this page is not listed as available, confirm with your VIN first, then ask the Horton Ambulance dealer service desk when the recall repair is open for your ambulance.
