2012 Grand Cherokee Issues

Our 2012 GC has had starter push button issues since last year. We have to push the button 3 separate times before the starter will crank and then the car starts perfectly. If you pop the start button out and use the key/fob in the hole, it starts perfectly. If you use the remote start it works perfectly. I posted this same issue last year. There are also some other issues that I believe are related. The cruise control dash indicator will not come on and therefore doesn't work. And the radio will remain "ON" for a while after the car is turned "OFF' and the door is opened. The brake light switch seems to work fine. Anyone have any thoughts? Thanks in advance! Happy Memorial weekend!:

Have you replaced the fob batteries yet? My 12 seems to have starting issues around the same time as the battery goes out in the fob

Sure sounds like a FOB, PEM, or PEM antenna issue, there are four of them running under the carpets. I forget if you need to have a foot on the brake to start with the button popped out, but if not, the brake switch could be intermittent. Its like a three contact switch, the brake lights being on a separate contact. There was a tread here awhile ago where a member replaced the brake switch and all was well. Did the dealer replace the brake switch or check the PEM antennas? Was the PEM ever replaced? Do both FOBs act the same?
