ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE

2 complaints

Driving home with no other cars around the forward collision warning goes off for no reason losing power and slowing down on it's own. This has been an ongoing situation since the car was new, I've made numerous attempts to have my local dealership look into this situation and all they tell me is to take video when it happens.

I was driving approximately 35MPH on a 4-lane road with no vehicles in front of me. The car came to a hard stop. The stop was so hard that my purse flew from the passenger seat to the floor. I was wearing my seat belt which tightened up but my body still moved forward causing me neck pain. I did notice briefly that a flashing yellow light was on the dashboard. There were no objects in front of me. The driver of the car behind me had to slam on their brakes and almost hit my car. My car stayed still for about 15 seconds and then the automatic brake was released.

I had a recall on this vehicle for the CVT software update which i got fixed by mitsubishi at the dealership but now its doing the same thing and seems worse, everytime I push on the gas it does not excelerate and usually gets stuck at 30-45MPH no matter how much i press on the gas, and the rpms get stuck at 3-4 thousand rpms which causes a safety threat when we are driving. I did some research and found out that this a well known issue with mitsubishi and its outlander sports vehicles I’m not sure what to do from here.

I was turning out of my neighborhood and as I accelerated to merge with traffic my car started jerking. My dashboard “D” symbol only started flashing on and off and then my transmission service required light came on, (just had it done 8/25 and it is 11/25) and the BSW service required light came on as well. As I continued down the street everytime I pressed on the gas pedal the car kept jerking backwards and forward.

BACK OVER PREVENTION

I have 40,000 miles on my vehicle, only owner and drive 28 miles to and from work a day. The entire Infotainment center is not usuable, I called the dealership I purchased it from and they said the warranty is 36,000 miles. How on a brand new car do you get 36,000 for a system that controls everything inside your car.

ENGINE

1 complaint

This was in a rental from National Car Rental from the Las Vegas airport. I was driving down the road at about 65-70 MPH when the vehicle's brakes just slammed on, and everything about the car just died. There was a huge groaning sound as it happened - kind of like when you are in 'park' and push the gas pedal and it revs really high. I tried shifting into neutral, nothing changed, and all the lights and functions of the car went out. I did my best to "direct" (couldn't steer) the car to the edge of the road. It was a busy remote highway, I was in the 'fast' lane. so could move over as far as I could to the other side of the white line while basically groaning to a halt. When I stopped all of the power shut down, the car would not restart and at first the battery and "service engine now" lights came off, then everything stopped. After a bit the battery came back on so I could at least charge my phone to use it to call for assistance. I have an email from National saying it appeared to be an engine malfunction. When this happened I was on Highway 93 between Las Vegas and Kingman Arizona (right around mile marker 30). It is a split highway with a dirt median. I was on the inside of the median. Fortunately when it happened there was no one directly behind me or they would have hit me. This is the main thoroughfare between NV and northern AZ here, so it is basically semi trucks going >70 mph the whole stretch. I had to sit in the car for 2 hours waiting for the tow truck to arrive. I did not get out of the car because I was more scared of distracting a driver and veering into me, whereas sitting in the car I was just as scared, but I thought at least I had an airbag if I was crashed into. I was honestly terrified the whole time. I sent numerous emails and made numerous calls that document all of this. I have pictures and video of the situation. The car was picked up by Jone's Towing from Kingman AZ.
