About a week ago, a "telematics error" message displayed, a single red light on the SOS button turned on, and it started beeping loudly. This has repeated multiple times. In this state the vehicle cannot automatically summon emergency help following a crash, and I cannot manually trigger an SOS call. More recently, June 17th, a new symptom has occurred. Vehicle's touchscreen display would not turn on. This display is required to access heating/cooling features including defrost/defog, and is used to show the backup camera. The dealer has informed us that these issues were all caused by a manufacturer-initiated over-the-air software update. We are currently scheduled to have a new software update installed to replace it on June 22nd.

What owners say
My screen begins to change the display without me touching it. It has interrupted my GPS directions, causing me to get lost. It has gotten worse over time, now causing my back up camera to either not display at all or become partially blocked by another application randomly starting on the screen. My emergency brake lights flash on my dash, and auto technicians tell me it is a malfunction with the electrical system, not something in my brake system that needs to be replaced. We have tried that. These problems I have been told are not the responsibility of the manufacturer. I don’t understand why. It is distracting, alarming, and because it is getting more frequent with more systems being affected, it puts the driver in danger. This is not due to wear and tear - it is due to a faulty electrical program.
My Mazda 2021 infotainment screen goes goes out usually when hit a bump and stays out until it sits awhile. Which when this happens there is no backup camera which is a safety issue. The Mazda dealership said it was the screen which they wanted $2900 just for the screen so I got one off eBay and it's still doing the same thing. Which I think its the CMU
Summary of Issue: The infotainment system in my 2019 Mazda CX-5 has been malfunctioning for a long period of time, and the issue has now escalated to the point where the system is unsafe and distracting while driving. Details: The infotainment screen intermittently “ghosts” and activates functions on its own—clicking through menus, changing settings, and moving erratically without any driver input. The system has also frozen and rebooted while the vehicle is in motion. This creates a serious distraction and safety concern. I previously reported this issue to the dealership, where they attempted a reset and told me to come back if the problem returned. The issue persisted and worsened. I recently returned, and the dealership diagnosed a communication failure between the CMU and the infotainment screen. However, they cannot identify any cause, and the screen itself has no physical damage and has never been struck. Mazda has declined to cover this under warranty, even though this appears to be an internal failure of components that should not fail at this mileage. Additionally, infotainment failures in Mazda vehicles have been the subject of prior complaints and service bulletins. Safety Concern: The malfunction causes the screen to operate unpredictably while driving, which distracts from the road and creates a risk of an accident. Because the system controls access to vehicle settings, Bluetooth, audio, navigation, and backup camera interfaces, the failure presents a potential safety defect. Requested Action: I am requesting that the federal safety agency investigate whether this infotainment / CMU communication failure is a broader defect affecting 2019 Mazda CX-5 vehicles, as dealerships cannot identify the cause and the failure poses a clear distraction hazard.
The display on my rearview camera is extremely foggy. It appears to have had a breach where water has leaked into the camera itself. I have cleaned the lens but yo no avail. I never had a clear screen, and at times it is so bad that I can’t see anything at all. In fact, I have already backed into the corner of a building in a parking lot due to lack of visibility. I can’t tell you the number of times I’ve attempted to back out and almost hit a pedestrian or another car driving behind me that I couldn’t see well. It’s a good thing I use my mirrors and rear window, or that could have easily happened. I wonder if the work that was done on my rear hatch from a previous recall may have caused the seal protecting the camera unit to be compromised. There have been a number of recalls recently from other manufacturer’s, so I believe this is a common issue that should be addressed in my case as well.
The infotainment system in my 2017 Mazda CX-5 exhibits dangerous behavior consistent with known defects described in the Mazda Infotainment Class Action Settlement (Case No. 8:21-cv-01355). The infotainment system and touchscreen repeatedly activate critical functions on its own (“ghost touches”), sometimes going black, changing critical settings, disengaging phone calls as well as unexpectedly activating phone calls, and navigation features engage or freeze unpredictably. These malfunctions distract from safe vehicle operation, requiring driver attention to manage the malfunctioning display. The vehicle’s display is integrated with backup camera, audio, and Bluetooth controls, so these repeated malfunctions cause safety concerns while driving. Mazda and the dealership have refused to repair the defect under the Limited Warranty Extension established in the settlement, incorrectly claiming the issue is unrelated to the CMU (connectivity master unit). However, these symptoms are identical to those described in Mazda’s internal service bulletins (CSP13 and TSB 09-022/17) and covered by the settlement. I believe Mazda is failing to properly address a continuing safety-related defect that impacts infotainment stability and driver concentration. These issues have occurred for years and are continuing nearly every time I operate the vehicle.
Back up cameras fail infotainment system reboots and maps on the system inadvertently counts stops plus changes volume at loudspeaker telling me “this is the level “ and is on highest volume. Which you can’t turn down. All are dangerously interfering with driving. Please put pressure on Mazda to fix and not just update software when the problem has been fixed called CMU
Infotainment system acts randomly, changing to max volume during driving, startling driver. Also changes stations, skips audio programs and distracting driver. Rear view camera has intermittently failed to show video feed when driving in reverse.
The rear camera dose not always display on the LCD screen, likely due to the ghosting issue with the infotainment system which randomly cuts in and out. This poses a safety hazard when backing up. Despite repeated complaints from other owners as well regarding the LCD screen, Mazda will not cover cost of replacing the LCD screen. I had a 2014 Mazda 3 for which there was a recall for the same issue and they covered it. So I don't understand why they won't do it for this vehicle. Being able to see what is behind the vehicle when backing up is a safety concern. I provided date of most recent occurrence, but this has happened multiple times before.
Display went dark and did not display. This is not the only time it happens. It acts like someone’s touching the screen even when in motion. It prevents the reverse camera from displaying.
