What's wrong?
The electrical equipment involved in this recall is the Thermo King inverter installed with the TriPac EVOLUTION or TriPac-e auxiliary power unit on 2014-2015 Freightliner Cascadia trucks. The inverter turns battery power into 120V AC household-style power for the sleeper cab, so drivers can run cabin electrical loads while the truck is parked.
On affected Cascadias, the 1100W, 1500W, or 2000W inverter can spark or overheat. That failure happens inside the inverter assembly. Once the unit overheats or sparks, nearby material in the cab or APU installation area can be exposed to ignition, creating a fire risk.
There is no warning sign before failure. If the inverter begins to overheat, the first sign can be heat, smoke, odor, or visible sparking from the electrical equipment, so treat any of those signs as a reason to stop using cabin power and contact a Freightliner dealer.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
An inverter fire can lead to a vehicle fire. If your VIN is included, schedule service promptly and ask the dealer how to handle the vehicle before the appointment. Repair will be free at any franchised Freightliner dealer once available.
What should I do?
- Check your VIN to confirm your 2014-2015 Freightliner Cascadia is included in this recall.
- Watch for Freightliner or Thermo King instructions before arranging the inverter replacement or refund.
- Contact Freightliner customer service or Thermo King customer service for repair routing, and reference recall number 14V588 when you call.
- Ask whether the inverter will be replaced free of charge or whether the full purchase price refund applies to your truck.
- Avoid using the cabin inverter until the repair path is confirmed; the inverter can spark or overheat and lead to a vehicle fire.
What happens at the repair
At the dealer or authorized service location, a Freightliner technician verifies that the truck has the affected Thermo King inverter tied to the TriPac auxiliary power unit. The remedy is replacement of the inverter free of charge, or a refund of the full purchase price through Thermo King. Because the remedy status is not marked available, confirm the repair path before scheduling. The final dealer repair will be free once available.
