I bought a used 2006 Grand Cherokee with 53,000 miles. On the fourth day of ownership, I started it and it died about 5 or 6 seconds later. I tried again and it did the same thing two more times, then stayed running. Had no problems for about 24 hrs, then the starting and dying continued again. I took it back to the dealership, they said that they got 3 transmission codes off of the commuter. Did a flash reset and updates; did not fix the problem. I was told it was the ignition switch and there was a recall on that part, but there was no part yet to fix the problem. Great!!! So I suggested a new ignition switch, reluctantly they put one in. Got it back home, with 4 starts on the new ignition, it did it again!! Every time that I have had to start it, it has taken more cranks to finally keep it running. I find it very difficult to believe that I could have 2 bad ignitions in a row. Not impossible though, I know. Any thoughts or ideas on what else it could be, would be greatly appreciated. Very frustrated!!
