general problems of the 2005 Jeep Cherokee

2 of my rear doors on my 2005 grand Cherokee broke off, so far total of 3 of my inside door handles are broken, this is definitely a safety issue if I were to get into a car accident and nobody can get out because door handles are broken. . . This should be a safety recall from Jeep on 2005 grand Cherokee's.

I began to notice some unexplained acceleration and deceleration. While driving, when the vehicle should downshift, I could feel a bump and noticeable hesitation. That gradually worsened to become major fluctuations in the rpm while both accelerating and decelerating. For instance, while steadily engaging the gas pedal to accelerate, the vehicle sometimes feels jumpy, does not accelerate smoothly, and if you look at the rpm's they jump up and down by 500 - 1000 rpms. Also, while coasting to a stop, when I am not braking but just allowing the vehicle to roll to the stop from say 45 mph, the same jumping occurs with the rpms. This sometimes causes the car to lurch forward if the rpms flare at a near stop, and once, as I was pulling out of my driveway, I stopped at the bottom of the drive but the engine flared and pushed the car out onto the roadway by about a foot. Eventually, this rpm issue began causing stalling. When I would stop at a traffic light, the engine would jump, and then the rpms would drop to zero and the engine would stall. Sometimes after just a few attempts I could restart. Twice I needed towed. My regular mechanic was able to replicate the stalling and saw and felt the rpm flares. He found no mechanical issues and suggested it was a computer issue and directed me to a dealership. 2 dealerships could find nothing wrong and sent me away with no fix. So, my regular mechanic did a computer reset which seemed to solve the problem temporarily. Reset was at 66,000 miles. Now at 72,300, problem is again becoming pronounced. I am getting nowhere with the dealerships and I'm honestly frightened driving this car. I cannot trust the car to accelerate or decelerate properly and I can't be sure the engine won't stall in traffic.
