Ignition Module problems of the 2007 Jeep Grand Cherokee

The Jeep has electrical stuff happening sporadically and does not start but with power but after 3 to 6 attempts starts right up. I turn key all power and bells go off and it makes a humming noise and 1 click noise dash says ' transmission over temp' the Jeep is cold so not over temperature. I've seen a lot of post about recall and also about ignition switch or module. I've only owned for 2 years and dealer said car had no recalls when I purchased. This happens stationary and also after driving about 20 minutes to destination and when I went to leave it took several times before starting. This has been going on for last 3 days but few messages randomly popped in information center few times before this had at dealer on computer no codes said it was okay.

The original problem was a battery light that came on when the car was being driven during a light rain. The solution suggested by our normal mechanic (who is very good and has serviced the car for years) was to replace the alternator and then it was noted the battery was bad. It was replaced since it was three years old. After the repair the car started to die intermittently while being driven. The car was taken back to the mechanic who check the diagnostics and said it appeared to be pointing to the ignition switch (based on their diagnostic flowchart). The mechanics service technician was able to duplicate the stalling in the vehicle when he drove it. Suggested we take back to the dealer who had replaced the ignition switch tumblers during the recall for this vehicle last November. The dealer wanted a $85 diagnostic fee to just check the switch. We received a download of the diagnostic codes which appear to be related to multiple failures of ignition modules but the dealer reported his service technician had not been able to duplicate the failure. He thought it might be the tipm but was sure it was not the switch. He was unable to tell us what the failure was and said we would have to pay for more diagnostics if he was to find out what exactly it was. I took it back to my mechanic who replaced alternator. However, as I was driving the car last Saturday it died after we stopped at a railroad crossing waiting on a train and then tried to cross the tracks after the arms had gone up. The crossing t-bones into another road and a very deep bar ditch at the side of that road. The crossing was a steep incline. Almost put car in ditch. My wife would not have been able to control and stop it as I barely was able to. After reviewing other similar complaints I now believe it is the tipm. This is safety related since all safety equipment is tied to this.

Since the first event the vehicle has stalled at the most importuned time. Two years ago it stalled twice while entering the new jersey garden state parkway on the same day. A year ago it stalled at 40 miles per hour traveling north on university blvd 100 ft from the dealer kelly Jeep dealership were the vehicle was purchased. I was made aware in July 2014 that there was an ignition key problem. By a local auto body repair shop owner. I remove everything from key except a small lightweight identification plastic tag a month ago it stalled again which turning onto high speed four lange expressway. I have contact a different dealer three months go and was told Chrysler is working on the problem. This is a very dangerous situation. I can't believe that in almost a year Chrysler still appears to have not inkling of owh to solve the problem prior to the public announcement in sept 2014 I had it to the dealer and was required to have vehicle tested by the analyzer. No problem was found. Even though I am 90 years old I still have sufficient strength to get the vehicle to a stop and if possible to the side of the highway in order to restart it. But I am afraid that if this happens with my wife while driving she will not be have sufficient strength to steer of brake the vehicle when it losses complete power. How is this any different than the accidently operation of the ignition key event that has occurred with general motor products. Last we I received a recall notice from Chrysler regarding the need to re-program the final drive control module (fdcm), that may cause the service $wd light to be activated making it impossible to change gears. I do not see that listed as a recall and I have never received any other notice. His apparently has a higher priority at Chrysler than the ignition key issue. Regards,.
