The issue is iron is depositing in the transmission due to a bad torque converter, this is a known issue with mazda and it doesn't seem to be something they are willing to cover and many people are experiencing this especially with the cx5 models. It causes jerking and chirping noise, plus will eventually ruin the transmission and will cause serious safety issues. Just look into the reddit threads

Driving about 20 to 35 mph accelerating I would get a distinctive one time chirp noise with a little bit of a stutter It happens every time I go about that speed accelerating. Thankfully my car was under pre-owned warranty but I have to get now. Three transmission flushes I have to pay $400 for and they have to replace a torque converter. I just got the car 10 days ago and only has 61,000 mi on it. Over the long term this could damage the transmission cause more and more issues

Low oil level indicator came on at roughly 55,000 miles only about 3000 miles after last oil change. Car was immediately stopped and towed to the nearest Mazda dealer. Dealership confirmed oil level was low. Car appears to me consuming excess oil. Oil consumption test pending.
