Question 1

What is Battery Degradation & "BMU Reset" Masking on the Mitsubishi Mitsubishi Outlander PHEV (GG)?

Accepted Answer

The traction battery naturally loses capacity over time. A major concern is the "BMU Reset" where a technician or seller resets the Battery Management Unit, forcing it to report 100% health (State of Health). This "masks" the actual degradation until the car relearns the true capacity over several weeks.

What is Electric Heater Failure on the Mitsubishi Mitsubishi Outlander PHEV (GG)?
