2023 Mitsubishi Outlander electrical problems

Filed Oct 19, 2026 · Electrical, Engine · GA

My 2023 Mitsubishi Outlander has experienced recurring high engine-temperature readings, misfires, and two overheating-related engine shutdowns while driving, creating a risk of unexpected power loss in traffic. The vehicle has been evaluated repeatedly by authorized Mitsubishi dealerships without identifying the underlying cause. Air in the cooling system was documented in September 2025, with the dealership noting it could cause the engine to run hotter than normal. In September 2026, a dealership again reported a significant amount of air in the cooling system. Previous cooling-system service temporarily improved the symptoms, but they returned. The temperature gauge repeatedly approaches H while driving, particularly with the A/C operating, and decreases when I slow down or turn off the A/C. These episodes occur WITHOUT an illuminated Check Engine Light or other warning message. During an earlier incident, the Check Engine Light appeared the following morning but went off before diagnostic codes could be retrieved. At the most recent dealership visit, I provided photographic evidence of the high temperature reading. The dealership's diagnostic equipment reportedly found no issue, but a technician's personal scanner identified a battery-related problem and additional codes. The battery was replaced, yet the temperature problem continued. On October 17, 2026, at approximately 98,395 miles, I again photographed the temperature gauge approaching H without any warning light. Despite multiple inspections, the cause remains UNKNOWN. I am concerned about another engine shutdown and a potential collision. The vehicle is available for inspection.

The camera does not activate when the car is put into reverse. It also doesn't activate when you are parking the car. The parking camera doesn't show on the screen at all. The recall on this item was repaired on my car but didn't fix the issue and the dealer refused to service it further without significant cost. This is a fundamental safety issue that should be addressed by recall and repaired without cost to the owner. The dealership that serviced a previous recall was Doug Smith Mitsubishi in American Fork Utah, however this didn't fix the issue. I also paid money for a diagnostic service and the service center could not determine why the camera is not triggering. The warning sounds/alerts still work. Please help. Thanks

The electrical system in my 2023 Mitsubishi Outlander has repeatedly malfunctioned since September 2023. The primary failure involves the dashboard completely shutting down while the vehicle is in motion, resulting in the loss of critical driving information such as speed and system warnings. The issue is intermittent but ongoing and may be available for inspection upon request. This failure creates a serious safety risk because I am unable to see essential driving information while operating the vehicle, placing both myself and my family at risk. The vehicle has been taken to authorized Mitsubishi dealerships multiple times for these issues. Repairs have been performed during these visits; however, none have permanently resolved the problem. The issue temporarily stops after repairs but eventually returns and continues to recur. The problem has been reproduced multiple times. The vehicle has been inspected by authorized Mitsubishi service departments on multiple occasions, but the underlying issue has not been properly diagnosed or permanently repaired. Prior to failure, there have been repeated battery-related issues and sensor malfunctions. The vehicle has required at least three battery replacements since purchase. These symptoms often occur before the dashboard shuts down. In addition to the electrical issue, the vehicle has also experienced fuel pump concerns, which have persisted despite repair attempts. This ongoing and recurring defect makes the vehicle unsafe to operate and remains unresolved.

Check engine light is on. My car is still under 5 year bumper to bumper warranty. My local mitsubishi dealership closed and the nearest one is hours away. I also have a recall. I have called mitsubishi customer service several times only to be put on hold without the ability to talk to someone to get these problems solved.

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.
