I have a 2021 GC Trailhawk, 3.6L gas engine. 21,000 km. Runs perfectly and until recently, I never had any starting issues. Now, every once in a while it behaves erratically during start up. One of 2 things occurs. 1. When you press the starter button it will crank over rapidly but won't start, and will just keep cranking. Not even a hint of it catching and trying to start. Hit the button again to stop it, and then immediately hit the button for another start cycle and it starts and runs normally. Or, 2. It will start right away on button press but chugs and vibrates as if it's only running on 2-3 cylinders. Shut it off, and do another quick restart, and again it starts normally and runs fine. It's never done it with the remote start, and only happens when you press the start button. Seems like either no fuel, or not enough fuel. I always keep gas tank fairly full. I get NO fault codes on the OBD scanner. NO other issues at all. BUT, it's starting to happen more frequently, so something is breaking down. Any clues or suggestions are very welcome before I take it to the dealer ? THANKS folks !
