What's wrong?
The WiFiRanger in these 2018-2019 Newmar motorhomes is the onboard wireless networking equipment. Its power supply feeds electricity to that equipment so it can run while the coach is in use or powered at the campsite. That power supply is part of the electrical equipment, not the engine or drivetrain.
In recall 19V257, the defect is overheating in the WiFiRanger power supply. An electrical power supply is supposed to regulate power without building excess heat. When it overheats, the affected part is no longer operating within its intended range, and the heat becomes the problem Newmar is recalling.
There is no warning sign before failure. Owners should not count on a light, message, smell, or change in WiFi performance to confirm the issue before the power supply overheats.

The scope spans multiple Newmar motorhome lines from 2018-2019, all tied to the electrical equipment component.
