general problems of the 2007 Jeep Cherokee

I am writing to you requesting your assistance in finding out what is wrong with my 2007, 67,000 mile Jeep grand Cherokee laredo. For approximately four months while driving the car it has been randomly miss firing, bucking and surging, and stalling when coming to a complete stop. The unpredictability of the cars speed, bucking and surging, and stalling when stopped is a major safety concern to me because this occurs without notice on both street and freeway driving. I have taken my car to the nearest Jeep service dealer, crystal Chrysler Jeep three times now and they have not been able to diagnose the cause to this problem. In fact, my car has been in the service department at crystal Chrysler for nearly three weeks now, and they cannot identify specifically what is causing this malfunction. My frustration over my beloved Jeep grows because without finding the cause there is no telling when my car will be ready. This experience now has me questioning the reliability of Jeep vehicles and the confidence in service dealers like crystal Chrysler. Please help me find out what is wrong with my Jeep vehicle.

Was driving and vehicle would no longer switch gears from first to second. I was on freeway in construction area that was down to one lane and could not pull over for approximately ten miles. Not happy at all since the vehicle (2007 Jeep grand Cherokee) has relatively low miles for a power train problem. My car is currently in the shop, but research shows this is a common problem with my model and a dangerous and expensive one at that. How is this not a recall?.

Driving down road and engine stalled. Loss of power steering and power brakes. Put car in park and the car still moved wouldn't restart had to switch ignition off and take key out of ignition before engine would start. Stalls at random without any engine malfunction lamps. Hazard to be driving on road. Problem still unknown and vehicle is out of extended warranty.

Jeep does not start. Message saying transmission temp over.

Was pulling from a stop sign when the vehicle suddenly shifted to fourth gear without touching shift left lever causing the vehicle to accelerate very slow and was almost hit by cross traffic because I could not get out of the way, luckily they swerved around me. I have read multiple complaints of same problem with shifting out of control. It must be a manufacturer defect. If it had not been for an alert driver the situation might have turned out differently for my family and I. Jeep needs to remedy this problem before somebody is killed.

2007 grand Cherokee overland 3. 0l diesel. For the past year or so the lights on the dash will all come on similar to when the car is first started. Recently the speedometer and tach will shut off as well. If this were a gas engine the engine would probably also stall. Numerous times at the dealer no change. I believe this related to the 2008 grand Cherokee recall.
