Noticed a decrease in gas mileage and check engine light on. About 1 month after radio would pop loudly gauges on dash would act erratically, digital mileage screen would flicker, vehicle stalls while driving or sitting at a stand still and then restart on its own. While driving and it stalls you loose steering, antilock brakes. Car returns to normal idle and symbols stay lit on dash, (brake, airbag, check engine light, etc) brought to dealership code po123 so replaced the throttle/pedal position sensor switch a. Dealership said that would resolve the stall. 2 days after repair vehicle stalled, instruments were erratically going from 0-100 MPH 0 rpms-? No antilock brakes, steering, etc. Whole vehicle looses power. Brought to dealership with all instrument lights lit on panel and no diagnostic codes would populate. After this happens and the car is shut off the next restart has a sluggish restart. Battery was checked multiple times and is good. Occurrence is about 8 times a weekly intermittently. The consequences is it happens with no warning, puts driver in dangerous situation due to stalling when ever it decides to and loss of control of the vehicle. Also on posted forums this is discussed heavily and nobody seems to know how to fix this very unsafe and potential deadly fault with jeeps. They recommend to replace the PCM but I have been told this is a 50% effective resolution and dealerships I called have stated this issue is well known and none of them have been able to find the cause.
