Oh man, m very sorry to hear this. Keep us updated on how your issue is handled.
Thanks @dougal, will do. So far I have no reason to doubt that Mazda will come through, but I'll keep my fingers crossed anyway.

@sm1ke - you have the Mazda block heater installed right? I don't think these are installed for us in B.C. but with a move to the interior on the horizon, it may have to be a future install.
Do you use yours often?
Any word from the dealer on the coolant issue?I had a scheduled dealer visit to troubleshoot an intermittent issue. While the car was in their care, I asked them to look into the potential coolant leak issue as well. I had my UoAs printed out just in case they were able to look into it for me. They got the car on the lift and looked for any signs of an external leak, again they couldn't find anything. I requested that they refer to the printed UoAs, and they said that they have photocopied the reports, opened a ticket with Mazda, and sent the reports to them for review.
I suspect that I'll be asked to provide maintenance records at some point.

The problem is that they don't have any loaners, and apparently there aren't even any rentals available
That’s crazy. Hope there aren’t any issues with your vehicle! Sounds like you’d be out of a vehicle for a long time
Ok, so a bit of an update. The car is scheduled to go to the dealership on Feb 3rd, with pickup scheduled for Feb 8th. The service manager I'm dealing with now appears to be pretty forthcoming with what's happening. He says that Mazda Canada suspects an external leak is the cause of the gradual coolant loss, and provided him with documentation regarding what to look for. He says that the areas that need to be inspected require a more involved disassembly, which is why he wants me to leave the car with them for a few days. Mazda didn't mention anything about a possible internal leak or the UoAs I provided, but I'm guessing that they want to rule out the more commonly described external leak detailed in the recent TSB before considering other potential causes.
I also asked the service manager to look into a different issue, detailed in this thread. In cold temps, I get a clunking noise from the engine bay when I turn off the car. While they have the car, they'll be looking into that issue as well.
Hopefully the new mount gets you squared away!Update on the dealership visit. They said that the clunking was due to a frozen engine mount, but they didn't have the mount on hand and had to order it. Should be here tomorrow or early next week, at which point I'll bring the car back to have them replace the mount. We'll see if that solves the clunk. I did note that turning the HVAC off completely before engine shutdown did result in a slightly less pronounced clunking, but it was still there. If it's still there after the engine mount replacement, I'll ask them to check the HVAC systems.
Regarding the coolant slow leak, they took a closer look at the engine with Mazda Canada's guidance, and couldn't find any signs of a leak anywhere on the engine. They also pressure tested the coolant system for 30 mins and no leaks were reported there either. No engine or cylinder head replacement was offered as a result, but I will continue to monitor and test the oil, and I'll follow up with Mazda Canada directly if necessary. At this point, I think there is either an internal coolant leak, or the lab I'm using is somehow misreporting the numbers. I'll try a different lab for my next UoA to rule that out. I just checked the engine oil on the dipstick as well, no visible signs of coolant mixing with the oil after about 2000km.
You may have already answered this and I didn’t catch it, but have you needed to top up coolant at all? Any fruity smell from the exhaust? That was the first sign of an internal leak on my previous vehicle. Next came slight coolant lossAt this point, I think there is either an internal coolant leak, or the lab I'm using is somehow misreporting the numbers.

Any updates on this?Car went back in for the frozen motor mount replacement yesterday. I left my dashcam running when I dropped it off at noon. Picked it up about 3.5 hours later, after I got the call that it was ready to go. I just went through the dashcam footage and saw that the car was actually in the shop for about 30 mins, 20 mins of which it was up on the lift. A master tech did the work.
When I got home, the clunk was still there. Will drive it for a couple of days to make sure it's consistent, and I'll also try turning HVAC off a few minutes before turning the car off to see if the noise is related to the HVAC system, then follow up with them.
Going to also monitor coolant levels, and if I notice it has dropped again, I'll use a different lab for the next UoA. At that point I'll go straight to Mazda Canada.
