When I am accelerating, pushing the gas pedal the rpms go down significantly then riser significantly. Now there is a deep rumble or vibration if I go above 50 and the check engine light is on. I live in flat terrain with occasional hills but drive mostly highways.

I'm not sure if it is in the motor or transmission of my SUV. What happens is when I am driving on the highway I push down on the accelerator and its as though my car is standing still then a few seconds later the accelerate starts to work and move the car, this has happened a few times and I have almost been hit from behind because of this. I no longer drive my car on the highways because I'm terrified that this will happen again while on the highway and I will be crashed or even killed due to what ever is going on with my car

When I push on gas, the car never shifts gears! I can start out slowly with a little gas peddle pressure, but when trying to get up to speed and merge with traffic, it will never shift into a higher gear! it stays at about 20mph and engine revs to red zone unless I lift off gas. I don't even get gas peddle half way down. Transmission roars, car doesn't go, and I can't go forward but at a slow crawl unless I pull over, let off gas completely so car can settle, then try again. It won't shift in AWD or 4WD and I old lady, I don't troomp N rocket. I just want to get up to 55mph within 1 mile without sending my engine into dragonflies and half a tank of gas gone! I asked dealer and he blew it off as a slow startingvehicle, but it's getting worse and tyranny not shifting right. Have to find a Mitsubishi service center.
