Land Rover is recalling over 3,000 Land Rover Discovery Sport and Range Rover Evoque MHEV vehicles from the 2020 model year because of potential electrical fires. Here's how it breaks down (have your lab goggles ready because we're about the get really scienc-y here for a second)...

The vehicle's 48-volt electrical systems overloads → causing the metal oxide semi-conductor field effect transisitors to break down (MOSFET) → leading to a short circuit in the DC-DC converter.

There will be warning signs when this happens. Whether it's from a "battery warning" console light, or smoke and a burning smell coming from the engine bay.

Land Rover believes a software update can prevent these overloads and plans to start the recall on December 18th.
