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 was driving on the highway on a trip and out of no where my car shuttered and then flashed service transmission soon, I pulled over and my car would no longer drive, reverse or go into neutral. The tow company reset my battery to try to reset my car system. After that my car wouldn't really go past 60. I followed the tow truck to the nearest town and it stalled again at the light and I could no longer go at all, my car locked up and wouldn't reset at that point. It's an $1100 tow back home. The CVT transmission really needs to be rechecked and recalled. I've found too many issues and the same complaints but can't find a recall on it at all.
The engine shuts off while at idle for stop lights, stop signs, and on occasion brief stops such as reversing and turning. The battery has been replaced, the alternator has been checked, & the catalytic converter was checked no problems there. However the problem persists with no warning/engine/battery light on. This is a big problem when trying to safely operate the vehicle especially if others are expecting me to go and then the car shuts off
Car has several problems with the transmission causing many safety concerns. Riff shifting and loss of power when trying to move car sometimes. Very dangerous condition having it towed to mitchabichi dealer..
