Those remote starter are known to cause issues like that. Ill start first by disconnecting the remote starter and check again for any changes.

Anyways after the battery was replaced with the best Interstate had in this size, I measured the battery drain:
Right after off: ~2.5A
~2min later: Relay clicks, ~2A
another couple minutes: 0.5A
After another ~30s : 0.35A
5 min later: 0.2A

Locking it didn't bring it below that. All lights were off.

Seems a little high. What is normal?

We do have an aftermarket remote starter.

I would say 4yrs is pretty average on a modern car with lots of electronics. 5yrs sometimes, but 4 is pretty good.

Definitely not a design flaw.

And I am that Mechanic who keeps warning CX-5 owners to always lock their vehicle.

I know this is an old thread, but seriously? I rarely lock my cars at home as they are in an enclosed garage. No need IMHO. I would certainly fight that one out with insurance if it became an issue.

The display warned about the key system and said to take it to the dealer. I checked the battery and it was discharged. I charged over night. Bottom Line move the shift lever to park BEFORE pushing the Start Button. Due to the trouble I've had with the GPS & phone etc. previously I should not have gotten the tech package.

My wife wasn't able to start the engine, she didn't even shift the gear from P and all the alarms were ON. However when I arrived I pushed the start engine with hitting the break and I had the security indicator light ON, according to the manual it maybe the remote battery, I replaced the remote battery but still the engine won't start!.
note that I have almost fresh battery only 3 month old, eventually I jumped the battery and the engine start, the following day the engine start with no issue and I suspect its the alternator because the belt went off 3 month ago but the mechanic assured me that the alternator output is ideal!.
At the end I wasn't able to find the root cause but I claimed a new battery based on the warranty
weird ha ?

2013 and 2014 had a common problem with the Park sensor wearing out, the radio and accessories intermittently stay on after shutting off car. Battery would run down. $55 part and an hour to self-install with moderate difficulty.
