After 7 months, I have failed to try and determine what is causing the problem, there are no error codes, and the service dept. cannot "Reproduce the problem" After the vehicle is driven 20-25 miles and parked for at least 5-6 hours it acts as if it does not want to start, it's not a battery issue. The starter turns the engine over with a regular cycle then the starter cycle speeds up to try and start the vehicle, almost like the vehicle is out of gas/no ignition. Sometimes it starts after the extended crank, sometimes we have to turn the ignition of and try again. The funny thing is that it never happens on the first start in the morning but happens almost every time when going to lunch and going home at the end of a work day. The frequency with the problem is beginning to increase and I don't want to get stranded somewhere because the vehicle decides it does not want to start and the dealership cannot reproduce the problem. Any suggestions?
