NHTSA complaint #11638649

Owner complaint summary

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.
