If your car is under 50 miles left in the tank it will start then immediately stop 10 seconds after.

Also if you have any codes (check engine light, etc) it will do the same.

 

Neither of these circumstances apply (see my list).

 

Try remote starting when you are in full view of the instrument panel (from the outside) and see if a message appears. It may tell you on the display the remote start was canceled for a reason

 

Check your oil level!

 

The weird thing is you saidthe engine tries to start but dies right away.

So according to the manual (at least for the '21 model) the following must be met before the engine will start:
Gear in park
Doors closed,
Hood closed
Liftgate closed
Hazards off
Brake switch inactive
Battery at acceptable charge level
PANIC button not pushed
System not disabled from previous remote start event
Vehicle security system indicator flashing
Ignition in off position
Fuel level meets requirements
Vehicle security system not signaling intrusion
Malfunction indicator light not illuminated

But all that gets checked by the computer I assume before it even thinks about starting at all, except when the fuel level is too low. I know for a fact it will still start and run for maybe a few seconds before shutting off if the fuel is too low.

Then the following are cancel messages on the evic:
Remote start canceled - hood open
" - door open
" - fuel low
" - liftgate open
" - timer expired
Remote start disabled - start vehicle to reset

I'd say something might be wrong with your fuel gauge since you said it won't start even when full, but I assume you'd see the light on all the time if that were the case. Idk why there would be one sensor for the fuel light and another for the remote start reason

 

Hoping I can find a solution here rather than pay the dealer a service fee for something that may be an easy fix.

If I double-click the remote start button on my keyfob, the horn honks, the lights blink and the engine briefly tries to turn over, then stops. I've searched the forums for some tips and none of the "usual suspects" seem to apply.

It fails whether the car is locked or unlocked.
I've not remote-started it 3 times in a row without starting it via the dashboard, so it shouldn't require a "reset."
The gas tank is full.
Transmission is in Park.
This has happened at multiple locations (church, neighbor's house, at home in the garage).
I've tried with both my keyfobs, so I don't believe it's a keyfob battery issue.
I have no check engine light or other warning lights on the dash.
It has always worked fine in the past. This behavior only started last week.
The engine immediately starts up via the dashboard start/stop button, so it doesn't seem to be a car battery issue.
Any suggestions?

I have the same problem… after the normal lights and lock behavior, the starter hits for one “chunk” and the display goes blank. Standard push-to-start works fine.
I see that there TWO BATTERIES in the compartment under the seat. Which do I test?

 

Test both as they work together and if one is bad then replace both together. Add your signature so that we know you have the V6 when you post a question.

 

I updated my info. This is a 5.7 R/T. I was wrong about the two batteries deal. After I opened the well, she has only one. Getting it tested tomorrow.

 

Ours was a bad battery on our Jeep SRT. Same issue

 

Plan on replacing it since it's 6 years old. It's good preventative maintenance.

 

FIXED! Battery replacement took care of everything. Procedure was a royal pain, though.ugh.
