There may be age related issues that can appear, unannounced as vehicles age along with parts, and a few items may be at the top of this list with your 2017/8yr old car and relatively new battery in mind.

1-Are both battery cable connections clean and free of corrosion, powdery white/blue deposits from battery vapors venting?

2-While starters have no time limit when they wear out, the main issue with starters are normal wearing down of its internal brushes. Most starters outlast vehicles but the ones wearing out occur from a combination of numerous starts per day over its lifetime, ill maintained engine when hard starting occurs with starter times increased on each start, poor main electrical connections, etc, contributing to starter wear.

3-In automatics, the shift lever has a safety switch to prevent starting in D or R. Safety requires automatics in Park or Neutral, when the safety switch closes to allow the starting circuit to operate when the ignition switch is turned to START. Try shifting to neutral and start. Two results; good starting in neutral may suggest partial misalignment of the Park/Neutral safety switch mounted on the xmission or similar failed starting as if in Park position. Similar failure to start suggests; battery, battery cables, their connections, starter and one or two main ground connections (battery negative to chassis, chassis to engine block).

4-The mechanical ignition switch may be worn when turned to START. 12v battery power is sent from the START terminal to the starter solenoid to initiate starting. Heavy duty electrical contacts inside ignition switches wears with no time limit when they become intermittent.

If you are comfortable underneath the engine or can measure voltage on one of the starter terminals from above (the smallest terminal on the starter), this may help narrow the problem down. A multimeter measuring for 12v (negative probe on engine/bare chassis) when the ignition switch is turned to START position. When 12v is measured on the small starter terminal, this verifies the ignition switch operating correctly and wiring to the starter.

Thank you! That's a ton of good info, which should help me narrow it down. I appreciate your help!

 

If the no start condition also includes no lights on the dashboard when you turn the key on you've got something further Upstream not turning on whether it's a relay possibly bad I'm not sure.

 

It does. It's like there's no battery in the car. Yet, if I hook a jumpstarter to it, it fires right up. Lately, it has been starting without a problem. These kind of sporadic events are the hardest to diagnose.
