2 Loud Engine Noise problem

Failure Date: 04/30/2010

1. Top intermittently leaks on/near the passenger door, and when there is snow the top acts like a sponge and saturates leaking water everywhere inside the Jeep. I have driven and been in soft tops most of my life and I have never seen a soft top saturate that badly that it soaks the inside of the Jeep. Originally the top leaked terrible anytime it rained along the top of the windshield and passenger side, 4 times I called to complain 3 times they told me it was my fault for putting the top on wrong in winter the 4th time they acted surprised and said OH btw there is a service bulletin 2. The engine makes a terrible high pitch whistle/siren noise from the engine intermittently. It last anywhere from a few minutes to a few hours. I have this on video 2 times and dan’s Jeep has heard it also along with many coworkers friends and family. 3. The steering wheel makes a terrible noise when cold initially and recently is making the noise in lesser severity even when warmed up. The noise is like dragging a nail across a spring. 4. Twice now my Jeep has had a serious idle/rpm problem I do not know what to call the problem. Saturday the 22nd of October 2011 I started the Jeep, it idled fine. I popped the hood open with a friend to see if we could hear the squealing noise when I gave it gas. When I gave it gas the Jeep dropped in rpm and acted as if it was going to stall out. Experimenting with the amount of gas no matter how far I pressed the gas pedal it continued to sound like it was dying. Friday the 28th of October after driving for well over an hour the Jeep was making the high pitch squealing/whistle/siren noise…. Again and at a stop light I went to give it gas as the light went green and the Jeep dropped in rpm and began to stall out it seemed. About 10 seconds later the Jeep started acting normal and accelerated.
