Thank you so much for posting the actual TSB. I searched the Internet just now but could not find any TSB info related to 2019 or 2020 CX-9s. This info is gold. My car definitely falls within this range.Yes, you just need to check to see if your VIN is among those that are affected. If your vehicle has the parasitic draw / dead battery issue and you’re VIN is not on the TSB let your dealer know. They only discovered this in April and I had to push my dealer to elevate it to get Mazda to acknowledge the problem. They may still be learning the extent of it.
I called the local dealer who says I need to bring it in for an inspection (leave it for the day). If they find the problem, they will order the part. There is no pre-ordering the part. The first available appointment is 10 days from now. They are unusually busy.
