2023 Mitsubishi Outlander: sudden loss of power

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.

While driving after leaving the dealership, the vehicle began jerking, hesitating during acceleration, and losing power unexpectedly. A flashing check engine light briefly appeared and disappeared. The sudden loss of normal engine performance created a serious safety hazard because the vehicle could have stalled in traffic, increasing the risk of an accident or collision. I also have eight children, including [XXX] twins, and the loss of transportation has prevented me from reliably getting my children to school, medical appointments, and obtaining necessities.

In any instance where the electronic shifter does not have power, vehicle cannot be placed into neutral manually to be pushed to safety. Vehicle shuts down, immobile, in place with no warning. I was in drive for approximately 30 minutes. I put the vehicle in park, then in reverse to back out of a parking space. The car was never turned off. When I went to put the vehicle into drive, the entire car lost power. There was no warning. The car was completely immobilized perpendicular to traffic. Because the shifter is entirely electronic, any time the vehicle loses power (battery, alternator, electrical issues, chip processor problem) the car cannot be placed into neutral and there is no manual override. The battery power failed with no warnings
