Mitsubishi Outlander check engine light comes on

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle experienced an apparent engine failure involving the engine cooling system and possible head gasket and/or engine damage. Prior to failure, the vehicle had a strong sweet coolant smell and was later diagnosed by the servicing dealership as having a coolant leak and possible engine-related damage requiring engine replacement. The vehicle is currently located and available for inspection at Don Herring Mitsubishi. How was your safety or the safety of others put at risk? 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. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Don Herring Mitsubishi inspected the vehicle and identified a coolant leak and possible major engine damage. The dealership advised that the engine may need replacement. The warranty company, CNA Extended Warranty, stated the dealership’s submitted notes referenced a blown head gasket and requested further teardown and inspection before approving repairs. The vehicle remains unrepaired while awaiting further action and/or engine replacement. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by Don Herring Mitsubishi and reviewed through CNA Extended Warranty as part of the repair claim process.

I was driving home from work and I came upon a red light as I was slowing down the car started jilting as I went to take off I started jilting again but then smoothed out. The check engine light, ABS brake light and speed traction off light came on.They just all popped on. At the next light it did the same thing , it started to shutter and loss of power on taking off. It was sputtery at the same time which could have caused an accident! I finally make it home in about an hour later I had to run out to the store to get a couple things. I put it in reverse and it started to jitter again so I put it in park I checked all the fluids everything was fine Don't know why the lights were on. Again I put it in reverse Go to pull out of my driveway it starts to jitter. I put it in drive very slow getting up to movement. I slowed to stop at a light and it stalls out right in the middle of the intersection I try to start it back up , it does but now it just will not go anywhere!! there was no warning no loud bangs, pops, or squeals, no loud anything it just stopped. It will engage in each gear but refuses to go anywhere. it feels like it wants to go but it's just not going. This is very dangerous I could have gotten in a serious accident being in the middle of the intersection like that. this problem needs to be fixed upon looking on many forums and internet sites this seems to be a very common issue with the CVT or the 2009 or any outlander for that matter. My car was made in Japan I guess because the VIN starts with J I'm not sure of how to get any recalls from there or if that matters. I'm not sure the history on my vehicle neither or where it was registered last. I wish I knew when and where the repairs have been done for the recalls that my vehicle may have had. My car is doing exactly what the recalls were for; MMNS's number SR-15-002 in June 15th 2015 and also mmna's number SR-18-001 I did change both CVT filters and fluid also the oil and oil filter. Still nothing.

1. On hot/warm days when I start my vehicle it will run then die and give me the code for Mass air sensor which I replaced but it keeps doing it; the check engine will stay on for a while then turn off until it does it again. 2. When driving and I go over a speed bump the suspension grinds or does a hard squeaking noise. 3. The USB in the center console stops working at times or when move the charging cord it disconnects for a few seconds. 4. Internal lights work when they want to, I thought the bulbs where burnt out and replaced them but they still come on when they want to not everytime a door is opened.

My Mitsubishi vehicle has an open recall related to a drive belt issue. Mitsubishi confirmed the recall, but the company have not completed the repair or scheduled an appointment, even after several attempts to contact them. The vehicle has stalled multiple times while driving, including on city roads. When it stalls, the check engine light comes on, and the car loses all power. I have to restart it to keep driving. This is a serious safety risk because it happens suddenly and could lead to an accident. The alternator and battery were both tested and are in good condition, so the problem appears related to the recalled belt or electrical system. The issue was confirmed by an independent mechanic, but Mitsubishi has not provided a repair or timeline. The problem continues and makes the vehicle unsafe to drive, especially in cold or highway conditions.

The car has severe rust on the frame to the point of the rust corroding a hole in the frame making it unsafe to drive. Black paint has been applied to conceal the extent of the rust, demonstrating clear intent to mislead and a disregard for human safety. The catalytic converter has been aftermarket welded into place and failing emissions. Other repairs needed cannot be done because the rust damage is to bad for mechanics to risk removing the bolts. Yes, the car is available for inspection. This dealership endangered my life, the lives of my loved ones and other drivers on the road with us by allowing us to drive a car with a damaged frame with could have caused a major accident. I took the car to my mechanic and the dealership's mechanic of choice and both said the car is unsafe to drive. The car was inspected by the Peachtree Mitsubishi Service Center and for whatever their reason may be, they told us the car was in great condition. After driving the car for a couple of weeks, we noticed the fumes and a knocking noise under the car. Also, the check engine light was on and the Peachtree Mitsubishi Service Center said it was the tire pressure. Despite my attempts to resolve this matter with the dealership directly, they have refused to take responsibility for their actions. I believe their practices violate consumer protection laws and pose a significant risk to public safety.

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.
