Car will not start!
Dealerships DO NOT always use a MAZDA branded battery and often will replace batteries on customers as well lot new vehicles that have sat on the dealership lot and have started to go bad or failed with other then branded OEM Mazda batteries. That is why new vehicle owners in their package get a separate warranty for the battery. While it is still covered under the standard Mazda warranty some non OEM batteries have better warranty coverage.
There are many retail auto parts in Canada that will load test your battery for free.
One last thing... most batteries that are "labled" Mazda are manufactured by the battery company Panasonic!
The actual date code of their batteries in melted along the edge of the top cover of the battery. You can get that number go to Panasonic and decode the exact date your battery was manufactured.
A 2020 Mazda is out of warranty (and so is the likely the original battery??) so really it would be better to find a service shop described in a previous response on your thread.

Suddenly, out of seemingly nowhere, my 2020 cx5 will not start. I press the ignition bottom, lights come on bright, everything seems fine. I can switch the gears in and out of park with no issue. I try and depress the brake pedal to start the car, but it will not depress.
Battery was changed 3 months ago...i do not know what to do. Thoughts?

The reading of the "complete" thread does not point to the wrong battery!
Many retail parts store will load test a battery and if it is bad install a new one for free
A Mazda dealership is not always the best place to go starting problems that could be more than the battery and most especially when it comes to out of warranty Mazda. You will get charged the full labor fees.

Lots of hostility here...wasn't what I was expecting at all lol.
Anyways, starter is getting replaced. If it doesn't fix the problem, youll hear back from me. If not, you'll know it's fixed.
I didn't come here to tell everybody I know everything but it seems many here are here to do just that!
thanks.

The other thing is we have many core and newly joined members that will often respond on the thread with information based on their experience of a single problem and what it turned out to be for them. Which is fine, but I on the other hand do auto service for a living and currently run a service shop and know what to ask a member to eliminate the obvious or give service advise on easy to check things that don't cost anything to try or look at first. And with some issues there is a specific order of process of elimination to find the cause and correct it.
A common BIG mistake many owners as well less experienced service shop and even dealership service departments do is replace parts that have not been confirmed as the problem. Often and more times than not this creates more unresolved problems to add to the original unresolved problem.
I never got the impression reading that you were doing anything except expressing what you have done what you seem to know and your thoughts on the problem.
If you look at my signature it in my nature to ask and or submit good service diagnostic information. And I do not mince my words.
If it does end up being your starter, then maybe if you also have your battery and connection checked then good for you in solving the starter problem and knowing the exact state of condition of your battery.

I can tell you the OEM battery in my 2020 did not last a year before it failed.
And yes, even failing, it would still start my CX-5 on certain occasions.
I had it replaced with much better aftermarket battery and have had no issues since, but I still get it load checked every fall.
Even new batteries generally only have a 3-year life span in modern vehicles (optimal output) and start failing after that.
I would not be surprised if I see that when I get it tested during my inspection later this month.
Hopefully the new starter will fix your issue, and you won't need to purchase a new battery as well.
Sure that's your onion based on not seeing a person's body language, demeanor or the verbalization, and also not reading such things a member signature 
Funny however after all this your starter was the needing to be replaced yet no indication of having your battery tested??
Solenoids number one cause of failing is a battery or connection (power supply cable) problem .

A final comment before I wrap this up - i noticed the way the starter was functioning felt different over the past 7 or 8 months although i couldn't pinpoint why. It wasn't that ir stopped working, it's that sometimes thr car would start instantly without the starter seemingly turning at all..it felt strange.
Anyways, in the end, it was in fact the starter. Solenoid was worn out. It got changed last night, and life goes on.
Thanks for contributing to the conversation either way. I appreciate it. Im sure you're ok, you just cane accross as a bit rude.
