Thank you in advance for your help.. I have a 1 owner 2018 JK Wrangler. 100% factory. About once a month, we have an issue with a no start.We have tried every tip and trick in the book, and here's the conclusion:.. if my wife will hold the key on in the vehicle, I can rock the Jeep by pushing on the bumper. The Jeep will start every single time. Can anyone help me diagnose what sensor is intermittently failing?

ps: New battery. No rust. Under the hood is immaculate. Electrical connections at fuseblock and battery are like new. Always garaged. No codes. Never any other issues. 30,000 miles. Automatic transmission.

 

Have you tried putting the transmission in neutral? Could it possibly be the sensor for shifter position?

 

Tried going thru all the gears. Only way it starts is in park and rocking the Jeep so the gears in the transmission engage back and forth. Thank you for your helpful advice tho
