Recall 26V144 affects 424 2023-2026 Gillig Low Floor buses for overheating high-voltage cables. Interim software repair is free, with final cable replacement later.
Gillig is recalling 424 2023-2026 Low Floor transit buses because the high voltage cable between the inverter and drive unit has a splice connection that reduces its amp capacity rating. Reduced capacity can overheat the cable and increase the risk of a fire; the Gillig dealer repair will be free once available.

What's wrong?
The high-voltage drive cable on 2023-2026 Gillig Low Floor transit buses carries electrical current between the roof-mounted inverter and the drive unit on the chassis. The inverter manages power for the Allison eGenFlex diesel-hybrid propulsion system, and the drive unit uses that power to move the bus. The cable has to carry high current without overheating.
On affected buses, the cable contains a splice connection that was not part of the intended design. That splice can extend beyond the cable coating and lowers the cable's amp capacity, meaning it carries less current than the design requires. During high power demand, the propulsion system can send more current through the cable than the reduced capacity allows. That overload can create heat at the cable and damage the line.
The driver warning sign is a Stop-hybrid telltale on the dashboard, which indicates a hybrid system fault. If that warning appears, the bus needs service before it returns to operation.
Who's affected?
Covers Low Floor buses from 2023 through 2026, all using the same high-voltage drive cable in the electric propulsion system.
| 2026 Gillig Low Floor | electric propulsion system |

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?
Reduced high voltage cable capacity can make the cable overheat and increase the risk of a fire. A Stop-hybrid warning light on the driver dashboard signals a system fault. If that warning appears, park safely and contact the dealer for guidance. Repair will be free at any franchised Gillig dealer once available.
What should I do?
- Check your VIN to confirm your 2023-2026 Gillig Low Floor bus is included in this recall.
- Watch for Gillig's follow-up notice for the final repair, and reference recall number 26V144 when you call with questions.
- Contact Gillig customer service at 1-800-735-1500 to confirm interim repair timing.
- Schedule the free interim software reprogramming that addresses the high-voltage cable overheating risk while the final cable replacement is being prepared.
- Bring the interim owner notice mailed April 14, 2026 if you received one.
What happens at the repair
Gillig's interim repair is a software reprogram that addresses the safety risk while the final fix is still being developed. For the final remedy, a Gillig technician will replace the high voltage cable that connects the inverter to the drive unit. Both the interim repair and final cable replacement are free under the recall. Out-of-pocket repairs already paid are handled through Gillig's existing warranty, not through a separate reimbursement program, because earlier failures would have been covered by warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.

Frequently asked questions
What is recall 26V144?
Recall 26V144 covers 424 2023-2026 Gillig Low Floor transit buses with a high voltage cable splice that reduces the cable's amp capacity. That reduced capacity can overheat the cable and increase fire risk. Gillig will provide an interim software reprogramming and a final cable replacement for free.
What should I do if my 2023-2026 Gillig Low Floor is on this recall?
Check your VIN to confirm the specific bus is included in recall 26V144. If it is, contact Gillig customer service at 1-800-735-1500 or a franchised Gillig service location for the interim software repair. The final high voltage cable replacement will be free once it is available.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. Gillig's remedy states that the interim software reprogramming and the final high voltage cable replacement will both be provided free of charge.
What is the safety risk?
The safety risk is cable overheating and fire. The affected high voltage cable connects the inverter to the drive unit, and the splice connection reduces its amp capacity rating. Gillig is using software reprogramming as an interim repair while the final cable replacement remains under development.
When will Gillig send the final repair notice?
Gillig has not provided a final remedy notice date. Interim owner notification letters explaining the safety risk were mailed April 14, 2026. Gillig will send another notice once the final high voltage cable replacement becomes available.
