When we turn the key, you can hear everything engaging, however the car will either not start, or will start after holding the key for a few seconds. We have changed the starter. No issue with the starter as the original was still good. Most of the time you can pull it into neutral and it will start. Changed the "safety neutral switch" and the car still has the issue. There is a screen that pops up that states "hill start assist not available." I thought the automatic versions of this vehicle were not equipped with this. Can you tell me possibly what is wrong with the car or what the possible issue is?
