What owners are reporting 4 most recent
The 2017 Mitsubishi outlander sport's CVT transmission hesitant while accelerating from a stop then it surges with power and the RPM fluctuates up and down continuously. When given gas the vehicle sometimes does not accelerate. This vehicle was not always like this. I recorded multiple video showing the RPM fluctuates constantly even in cruise control. I took it to local Mitsubishi dealership…
The vehicle sounds really loud when it runs. When I press the accelerator it sounds like it is in 4wd. It is not getting enough force.
Transmission failed, needs transmission replaced. Mitsubishi Outlander Sport gt 2017 car starts shifts into gear and won’t go just revs up. Towed to garage and told needs new transmission.
