Mitsubishi Outlander Sport transmission failure problems

Filed Jun 29, 2026 · Acceleration, Transmission · IL

Purchased used car in July 2024 and was able to drive it maybe 2 months and the transmission would not shift and would come to a complete stop. Not a safe feeling driving in 3 lanes of traffic on a busy highway at rush hour. Transmission light on and took to mechanic and was told this make and model is notorious for transmission failure and it needs replacing. The odometer is 86316 and car has been sitting now for two years. Of course we went exactly 100 miles over the warranty and now have to pay 5000-9000 dollars for a replacement with no guarantee warranty. So now we have the car paid off and can’t drive it because it’s out of budget to replace. Thanks a lot Mitsubishi for nothing.

I am filing this complaint regarding serious safety issues with my 2018 Mitsubishi Outlander Sport, VIN: [XXX] , purchased from Carvana in 2019. Recurring transmission problems have created a significant safety risk for me and others. About a year after purchase, the vehicle’s transmission began failing, and I replaced it in 2021. Despite this, the transmission warning light activates intermittently in stop-and-go traffic, and now the vehicle has started stalling on highways, creating a critical hazard by suddenly losing power. In 2021, I took the vehicle to a now-closed Mitsubishi dealership in Brooklyn, where I was informed that this transmission issue was not covered, despite it being a drivetrain problem that should have been under the 100,000-mile powertrain warranty. My research suggests this model may have a Transmission Control Unit (CVT-ECU) defect, potentially causing stalling. Carvana has stated this issue is Mitsubishi’s responsibility, as it is likely manufacturing-related rather than due to prior use. Given Carvana’s stance and the severe safety implications of stalling, I urge the federal safety agency to investigate if this vehicle, or others with similar transmissions, pose a broader safety risk. Summary of Safety Concerns:     1.    Recurring Transmission Problems: Transmission was replaced in 2021, yet the warning light persists, indicating unresolved issues.     2.    Stalling on Highways: Vehicle loses power without warning, posing a major hazard in high-speed traffic.     3.    Potential Manufacturing Defect: Research suggests a CVT-ECU defect, likely explaining the stalling. These issues leave me unable to rely on my vehicle safely. For my safety and others, I request an investigation into these transmission issues in the 2018 Mitsubishi Outlander Sport to determine if there is a larger safety concern. Thank you for your attention. I am available to provide further information as needed.  INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2015 Mitsubishi Outlander Sport is having problems shifting and accelerating. There is a Transmission service needed light that comes on the dash when turned on. Recently it would not go over 40 - 45 MPH, and continued to go slower. I had to turn the car off and back on which helped a little. I have taken the vehicle to the dealership and they confirmed the faulty transmission and they gave me a printed quote for a new transmission. The mileage is at 101162 and the main problem is when I try to reach 65 MPH speed I feel the transmission goes back to a lower speed so I always stock with 40 - 45 MPH and so hard to accelerate again. we own another 2014 Mitsubishi Outlander Sport with 196k miles on it and never faced any transmission issues we always change the J4 fluid and the filter on time. for sure there's something wrong with this year's model (2015) from the manufacturer because our 2014 Mitsubishi Outlander Sport with 196k miles is still sharp.

My 2015 Mitsubishi Outlander Sport transmission failed at 45,000 miles. I had my car diagnosed and was told I needed a new transmission. In addition, my safety was put at risk because my vehicle would not accelerate at a traffic light when needed to go. It would also not get up to speed when merging into the highway and it would not maintain the speed limit while driving. This was a very dangerous situation for me. I was not able to accelerate at stop lights, which could have caused me to get hit from behind. In addition to this, I was unable to maintain a safe speed on the highway. My car would only get up to 40 miles per hour when the speed limit would be 60 to 70 miles per hour. Furthermore, my car was taken to the Mitsubishi dealership service center and was inspected. I was told that I needed a new transmission. Lastly, the day before I took my car in to get diagnosed the serve light on my car came on and said, “Service Transmission Required.”

My 2015 Mitsubishi Outlander Sport is having problems shifting and accelerating. There is a Transmission service needed light that comes on the dash when turned on. A few months ago I had to start manually shifting which barely got me by. Recently it would not go over 25 MPH, and continued to go slower and slower until it stopped and would not accelerate at all. I have had to drive on the far right of the road with my hazards on and barely made it from A to B while cars zoomed past me. I had to turn the car off and back on which helped a little. I feel like when it is low on gas, that also makes it worse? I have taken the vehicle to the dealership that sold it to me who confirmed the faulty transmission and they gave me a printed quote for a new transmission. The mileage is at 89,811 and I've had it for almost 2 years. I first started noticing issues shortly after purchase when it would shake when idle once in a while or would have a hard time accelerating after stopping. The first time it would not accelerate was about a year ago. I no longer can rely on this vehicle for transportation.
