2019 Si Wont Start

[CyberLoki]

I have about 27k miles. CAI and tuner. Recently, my car won't start. It's happening with increasing regularity. I get in, logo flashes, but when I hit start button nothing happens. Once, I was not able to enter the car. When I attempted to unlock it, only the lights would flash. Same if I try to open the trunk.

$20 says it's the car's battery. If you've never had to replace it, now's the time. They only last, like, 2 yrs. I have a 2019 also, and had to replace it sometime last year.

Test your battery with car off should be 12.4 to 12.6 volts. If low check your fluid level and add distilled water on low cells. Is battery maintenance a lost art. Spend your money wisely. Takes 10 minutes to check and a dollars worth of "distilled" water.

Also happens when I use door handle or trunk. I have to use the actual key to get inside.

Awesome! I'll try this for sure.

Thank you. I'll try maintenance as suggested below. If not I'll replace battery.

When you remove the covers, if you see white corrosion on the plates it's pretty much a done deal.

That sounds like what I went through when my fob battery was dying. When my 12V lead acid went belly up, no warning. I was able to jump start it to get to a shop to get a new battery.

I've gotten low key fob bat warnings on the dash. Always replaced soon after the warning.

We had to replace the battery in my daughter's 2019 EX hatch. Sometime over the winter she couldn't get it to start, but of course it started for me. However as she was driving, it started throwing up scary error messages. An error for every single system must have come up, but the car drove fine.

Brought the car in for service and sure enough the battery failed. It was actually covered under warranty.

I replaced the fob battery and the car battery. Still happening.

I had this theory that something was actively preventing the starter from working. I know it has Mopar EVTS which I figured was the culprit. Interestingly, a light on the evts hardware continued blinking even after removing battery terminals. So, EVTS rep assured me the equipment is incapable of disabling the vehicle.

I found a temporary fix. When this happens a remove a fuse for what I think is the ignition system. Replace it and it everything works.
