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

I purchased this vehicle as a used car from a dealership. On my way home, the infotainment panel began to shout at top volume that this is the volume that navigation would be set at. The volume was so loud that it was startling, and it continued on until I had to pull over. I contacted the dealer, but they offered no assistance. The car continues to control itself at the panel ferning with the use of android auto so that you can't use your phone GPS for directions. The radio will control itself, changing stations, making loud beeps, and turning the volume up. There is no way to stop this feature because you can't turn the system completely off while the car is on. I can find no way to fix this on my own. I have tried resets, but have seen ample information about other people having this problem online. This does not seem to be an unknown problem and I don't know why there has not been issued a recall because it's very dangerous.

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

The ongoing “ghost touch” defect in Mazda infotainment systems is a serious safety hazard that should have triggered a recall. This issue affects vehicles from model years 2016 through 2023 and stems from a design flaw present from the beginning. While driving, the system can suddenly take control of the screen—changing settings, switching stations, adjusting navigation, and even blasting the volume to maximum without driver input. On multiple occasions, I have been driving at freeway speeds when the system suddenly raised the volume to its highest level, jolting me and creating a dangerous distraction that nearly caused an accident. Mazda previously settled a lawsuit regarding this defect but only offered a free software update as a remedy. When I visited a dealership, I was told I already had the latest update—and that it does not resolve the ghost touch problem. The dealership acknowledged that it is a known design flaw, yet Mazda is charging customers around $800 to repla

The contact owns a 2020 Mazda CX-5. The contact stated that while the cruise control was activated and driving 65 MPH in the middle lane of a busy six-lane highway, the contact depressed the accelerator pedal, and the vehicle was suddenly stalled and coasted to a complete stop in the middle of the highway.

The vehicle was later taken to the local dealer, who was unable to determine the cause of the failure and was unable to confirm that the failure had occurred. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 32,000.

While traveling on an Interstate highway, my passenger side curtain airbag suddenly deployed without any warning while I was driving. There was no collision or impact, there was no debris on the road, or any significant bumps in the road. There was a very loud explosive sound and then my entire passenger side was covered in blue. The sound was so loud that it left my ears ringing and left me badly shaken up. I lost all visibility out of my passenger side as all of my side windows and mirrors were obscured, and I knew there was traffic in that lane along side of me. It felt very dangerous and I had to rely on my lane change sensors to safely pull to the side to assess any damage. There was no evident sign of any impact to my car. All of the glass was intact, there were no scratches, dents or missing paint. The airbag fully deployed for no apparent reason and I was extremely lucky that I was not injured and that my reaction did not cause an accident when this happened. The car

Display screen (Infotainment system) will randomly change the settings of my vehicle and call people or change display features or volume control or directions that is distracting and dangerous to me as I drive.

Mazda has a known issue with their infotainment system and ghost touch. There was a recent lawsuit but ghost touch is not covered under the class action lawsuit. The screen will call people, change setting, and just click a bunch of things. This is extremely distracting when driving if I’m constantly having to fight to stay on my navigation screen and make sure it is not calling people. It’s a very well known issue that Mazda will not fix it and quotes around $500-700 to fix with a part that will eventually have the same issue. I have tried pleasing with Mazda and basically been told too bad. I just want my screen to work and not have to fight it constantly

I noticed an oil leak. I had it diagnosed and its a crack in the cylinder head, right above the exhaust manifold. This is known issue for Mazda's online. There is oil spilling everywhere. The oil burns off as it is driving. Smoke fills my car.
