I have a 2007 Grand Cherokee Laredo with the 3.7L and Iv'e been having some really weird electrical problems going on. I was wondering if anyone else has experienced this or has a fix for it.
This all started happening a few weeks ago, I was sitting at a stop light and all of a sudden my radio shut off for about 5 seconds and then turned back on. About 20 seconds later a few warning lights came on but it was so quick I didn't see which ones they were. I then drove a few miles down the road and as i was pulling into a parking spot my jeep completely shut off. All of the gauges were in the same spot before it turned off, and if I tried to turn the key nothing would happen. The doors would't lock, the headlights wouldn't turn on It was like there wasn't even a battery inside the car. I got out and wiggled the battery cables a little bit and the gauges dropped. then the jeep started right up and was perfectly fine.
After that day I went another week before the jeep started acting up again. this time I was driving at night time and all of a sudden the headlights would start flickering. Then the radio was doing the same thing where it would turn off and on again, but this time it did it a few times. I was close to where I was going so I parked. I was out for awhile and when I drove home everything was normal.
My alternator went out about a year ago and I replaced it as well as the battery. I know there is a recall out right now for the ignition switch which I am having the dealer fix this Thursday but I wasn't sure if that would cause all of this to happen or not.
