(BHA4-37-140) Metal
(BDGF-37-140) rubber
Both work. I had a 2017 and now a 2021 where my winters had the metal stems and are working perfectly fine.
I believe the changeover happened for 2021 Model year.
As you are in Canada with snow, I'd say the rubber stems are better as the mounting nuts...
Crystal Soul Red is a Tri-coat paint formulation.

The problem with the color is that it seems to show chips and scratches in the clear coat more than any other color.
OP had stated "but what has me puzzled the...
Signature Wheels are painted in Hyper Silver (3- stage paint - Black base, translucent silver color then clear). I believe the GTR use just the standard Silver paint on most wheels.
Dealership does not sell touch up paint for the wheels.
Since the area is so small, you'd get away with using...
We too also had a 2017 and now a 2021 and have noticed the tweaks with BSM. As stated above, they seem to have calibrated the unit to be less sensitive in my opinion.
Given the false alerts I had in the 2017, I've learnt to never trust BSM and still rely on the over the shoulder checking...
There are certain colors that show the stone chips more than others. There really is no difference with the color of the paint and chipping. If you drive on the highway, you're prone to get stone chips more so that if you are just driving around town at lower speeds.
Give yourself distance...
While I agree you should go back to the dealership as they initially did the install, perhaps a second opinion from a dedicated Tire shop if all else fails and you're not getting anywhere with the dealership.
Tire shops deal with one thing alone while the dealership may not have the specialty...
The Mazda lug nuts on the vehicles have been the same since early 2006 from all of the Mazda vehicles I've owned.
If you are going from 2018 OEM to 2019 OEM, I'd use the lugs you currently have. Not clear if the 2019 owner changed from stock.
Without pics, not quite sure what the differences...
Curious on why the car would be dead(not running) after 4 hours.
It doesn't seem like it ran out of gas. If it did run out of gas, the vehicle has systems to power down the interior lights/accessories after a period of time as I've sat in the car with the radio and door open and after 20...
Did you or do you frequently leave the sunroof open while parked?
How does the sunroof drain get clogged if the roof is primarily kept closed?
The first repair at the dealership did not address the situation. Take it back to ask them to fix and show you the blocked drain if they are claiming...
For the 2021, the Mazda OEM part # is BDGF-37-140. These are the rubber push in style with a different looking valve stem cap which looks much better for winter salt.
I have the older style BHA4-37-140 listed above and they work as well so both should work in 2017+ models.
You may not have seen it until now after all that time as the plastic starts to shrink and dislodge from the rim. Easy for pre-prep at the dealership to miss when brand new.
Glad it was a simple fix giving you peace of mind.
