What's wrong?
The 2020-2023 Nova Bus Lfs Artic and Lfs buses use retaining brackets to hold the Mobile Climate Control HVAC unit on the roof. HVAC means heating, ventilation, and air conditioning. These brackets keep the roof-mounted unit secured while the bus moves, turns, brakes, and rides over rough pavement.
On these buses, the bracket design was not validated enough for the actual conditions the vehicle sees in service. The brackets can break, which leaves the HVAC unit with less support than it needs. If the retaining brackets fail, the unit can detach from the bus.
There is no warning sign before failure. The remedy changes the attachment by adding four additional brackets, giving the roof-mounted HVAC unit more retention than the original setup.

What should I do?
- Check your VIN to confirm your 2020-2023 Nova Bus Lfs Artic or Lfs transit bus is included in this recall.
- Contact a franchised Nova Bus dealer to schedule the free HVAC-unit bracket inspection and added-bracket repair that keeps the unit secured to the bus.

What happens at the repair
At the dealer, a Nova Bus technician inspects the existing brackets that hold the Mobile Climate Control HVAC unit. If the brackets need reinforcement, the technician installs additional brackets so the HVAC unit stays secured to the bus. The inspection and added brackets are free under recall 23V763, with parts and labor covered. If you paid for this repair before the owner letter, Nova Bus's general reimbursement plan covers documented expenses. Contact Nova Bus customer service or bring repair paperwork to the service desk so the claim can be reviewed.
