- Mazda CX-9 GT 2018 White
Three months ago, my 2018 CX-9 started making a weird noise when using the adaptive cruise control or MRCC. When the system applies the brakes, it makes the noise that you can hear in my video. I took it to the dealer, and the master technician recommends replacing the ABS control unit, but the car is not throwing error codes or exhibiting a mechanical malfunction. Just the noise. I purchased an extended warranty service at the dealer. Sadly, the extended warranty provider refuses to pay for the part because their inspectors (no Mazda techs) say there is no malfunction even if the noise can be easily replicated and is noticeable.
Here is the video:

You can notice the noise when the system applies the brakes until the HOLD light is on.
Has anyone experienced or had something similar to this? If it is the ABS unit, I'm kinda scared that the system will fail eventually or during a hard stop. The only thing that comes to my mind is that months before the noise started, the dealer did a brake fluid flush and replacement. Maybe the flushing caused the issue?
