The rear backup camera on my vehicle goes on and off or dims considerably when I back up, not allowing me to see cars and people potentially behind me. This is associated, I believe, with an issue with the screen and infotainment system of the car, which I had checked out on 9/24/21 at a Mazda dealership. The screen goes on and off constantly, not allowing me to use the radio, bluetooth, etc. They said it is a chip issue that they have seen in many other Mazda 3's from 2016. Not being able to listen to the radio is one thing, but having the backup camera not work or work improperly is a safety issue.

There is a main board failure that controls the information screen and back up camera The part number is TC3M-66-9C0B. The screen will keep rebooting not allowing the back up camera to work. According to Mazda dealer personal Mazda will not cover this. This is know to be a regular problem with many of these cars

I have had to replace the battery on this vehicle three times in the last year. I have taken it to Mazda who replaces the battery. No excessive electrical power is being used with in the car. The car is driven regularly as well.

The infotainment system fails to work - it is where I can access information re: maintenance schedule, or any info that is associated with a lit engine light. In addition the charging system for my mobile phone has ceased working. This includes both the usb ports and the lighter port which can be adapted with a charger that works in that receptable. These are all safety issues as far as I am concerned. Not having information related to the vehicle engine light is a big issue, but so is the fact that I can't charge my phone on long distance drives. If I needed assistance, I would be unable to contact anyone without a working cell phone. Because the display also controls the ability to pair a phone with blue tooth, there is concern for other drivers of the Mazda 3 (mine is a 2016) will be using the phone regardless of the bluetooth malfunction. I have seen a safety recall on other Mazda's with relation to the infotainment screen, but I do not see one here. I wonder why? To repair this crucial component would cost many hundreds of dollars -- something I am not in a position to do. Mazda claims this infotainment center is not under warranty, but with so much important information and safety features embedded into it, I think it should be corrected by recall. Thank you for investigating this issue. Regina

The Mazda Connect infotainment system will begin to press random buttons and continue to perform its own actions, at one point resulting in it dimming my screen so low I could not see my backup camera screen, which is a huge safety hazard.

I drove my car to the store this morning listening pandora (bluetooth) and on my way back home the infotainment center just started to reboot continuously after I found out resetting it could help I did the back+nav+mute but it didn't work I went to the Mazda forum and found out this was an issue with many Mazda fans I also found out that replacement of the cmu is very expensive since this is an issue with so many Mazda fans why isn't there a recall to address this problem? my backup camera works and one radio station there is no gps and bluetooth just continues to reboot even while driving

Rattling/fluttering noise everytime I initially turn the car on with ac. Whenever the A/C was is on and I step on the accelerator. Now, it does it everytime I push on the accelerator without the A/C being on.

The infotaminment system computer is on constant reboot loop, making it along with all its features unusable. This is dangerous since the backup camera blacks out and also the hands free driving is unable to be used. The system was working fine in the morning and when I went to drive home it crashed after starting the car. Many others have had this same issue and Mazda has not recalled the part.

Sunroof glass shattered outward without any cause or warning. The sunroof was closed at the time and there were no cracks, no breaks, no leaks, no weaknesses identified. When it shattered, I was driving down interstate 25 at approximately 78 mph. Tires are properly inflated.

Temperature control stops working. The knob for temperature control will not move, the temp control link under dash disconnects. Windshield becomes fogged and cannot see out. This happens when car is both moving and stationary. Very difficult to deal with when travelling on freeways.

A sensor (yellow/orange color) appears on the dashboard intermittently. The settings in the car say "battery mgt. System malfunction". at the times when this error is not on the dashboard, there is no message that anything is wrong. My car only has 23K miles. The dealer will not do a sensor check because it is just over 3 years old.
