1) 12/20/2024: Took the car to a Mitsubishi dealer as the 'Check Engine Light' was ON for a few days. They erased the code but could not diagnose the cause. Returned home and could NOT charge the car using the same standard outlet (level 1) I used since I bought the car. The instrument cluster displayed the following (Please see Pic 1): a) Error message 'PHEV System Fault, Service Required'. b) Check engine light. c) Forward Collision Mitigation System [FCM] OFF warning light. d) Rear Automatic Emergency Braking [Rear AEB] system OFF warning light. e) Plug-in hybrid EV system warning light. Since 12/20/2024, I have been driving the car with these serious safety issues. 2) 1/2/2025: 'On-board charger' was replaced by the dealer. But the same error continued. Per dealer invoice, they "performed drive cycle pattern 3 and the code returned". Obviously under certain conditions, the erased code returned. 3) Since mid-November, 2024, I have been noticing two different EV range mileage. Please see Pic 2. My phone app showed (on 1/26/2025) a 51 mile EV range whereas the instrument cluster showed only a 39 mile range. All the errors still remain as of 1/26/2025. 4) Opened a case with Mitsubishi but they are refusing to respond with updates. With so many safety issues due to 'PHEV System Fault', I am afraid of taking the car out.

Vehicle does not operate at temperatures below approximately 10 degrees Fahrenheit due to manufacture failure to install a battery heater. Was inexplicably deleted from 2023 model year of vehicle. The heat pump system also does not work at low temperatures therefore an electrical resistance heating system is needed. Also, vehicles will not accept charge at low temperatures. The problem can only be confirmed at temperatures below 10 degrees. Vehicle warning lights confirm the problem is due to low temperature conditions. Research indicates numerous complaints that manufacturers are aware of and refuse to address. Could leave owner stranded if leaving vehicle in a cold location.
