2020 Mazda CX-5 Electrical System

I own a 2020 Mazda CX-5 equipped with the Mazda Connect infotainment system. The touchscreen display malfunctions regularly by randomly selecting menu items, jumping between screens, zooming in and out, and activating functions without any input from me. These “phantom touch” events occur even when the vehicle is in Drive, which means the touchscreen should be disabled — yet the system behaves as if it’s receiving constant false touch input. When this happens, I cannot back out of screens or use the physical control knob or buttons, making it extremely distracting and unsafe while driving. The dealer initially diagnosed it as a screen laminate issue, which they said isn’t covered under warranty. However, this appears to be a known defect in the CMU (Connectivity Master Unit) that Mazda has not properly addressed in many cases, even though there is an ongoing class action settlement about it. The CMU passed their diagnostic test, but the issue persists — and others have reported receiving full replacements despite passing those same tests. Mazda refuses to escalate or repair unless the screen kit fails first. I believe this is a defect affecting driver safety, especially since it continues while the vehicle is moving.

*This is not part of the class action lawsuit* Per attorneys for the complaint, this issue is not part or covered by that lawsuit* This is concerning the infotainment system and what is known by Mazda as “ghosting”. Mazda for safety disables touch screen while car is out of park or driving. The ghosting issue ( which simulates touching of the screen) has overridden the safety lock out feature. While driving or in gear, the ghosting issue will increase radio volume to max, start beeping, changing different features, place calls etc. This sudden unexpected “ghosting” startled me and distracted me from safe driving. This can lead to accidents. Mazda is aware of this issue as they issued a warranty extension due to a previous complaint with the NHTSA in 2019. However, Mazda did not change the defective part/s in their vehicles and the issue continues on 2020 models. In my 2020 Mazda CX-5 this issue has been happening for approximately 2 years getting progressively worse.

The contact owns a 2020 Mazda CX-5. The contact stated while driving at an undisclosed speed, the vehicle shuddered and lost automotive power and failed to exceed 15 MPH. The vehicle failed to return to normal operation. The failure had occurred on several occasions. The contact stated that the infotainment system was inoperative. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed that the ignition coils needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic where it was diagnosed that the CPU system needed to be replaced. The manufacturer was not notified of the failure. The failure mileage was approximately 80,000.

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.

The infotainment screen kept moving on its own disconnecting my map while driving. I took it to Mazda and they updated the software but the infotainment continued to malfunction . The same issue happened with Mazda CX vehicles in 2016 and 2017 and they issued a recall for those cars. My 2020 CX-5 is experiencing the same “Ghost Touch Screen” but Mazda had not issued a recall. I ended up having to replace the infotainment screen, paid $ 912.67 for a manufacturer issue that was not created by the wear and tear of the car. Maybe other consumers are having the same issue.

When driving the infotainment system will switch to sound settings by itself and play the navigation volume to full capacity and says something like "navigation will play at this volume". If I try to stop it or turn it down, it just turns the volume back up again & says the same message. This is dangerous while driving due to the fact it startles you and causes a major distraction. I have not had it looked at by the dealership yet. I have seen online where this seems to be a common problem among Mazda infotainment systems with a touch screen.

My Mazda 2020 CX-5 has the “ghost touch” issue with the screen, buttons on screen are automatically being pressed constantly, super laggy, buttons not functioning properly, making random phone calls etc. There are also incidences that the screen became totally black.

Sporatically and randomly, the user instrument panel will make changes and adjustments automatically. For instance, it will switch to nativgation at full volume and state that "the navigation will be at this volume" (at max volume) when previously muted. It's alarming. It will also randomly call the last person dialed over the car speakers. It switches settings on its own and beeps during that process for each change, which when it's not driver initiated, catches the driver by surprise. An employee confirmed that "ghosting" is an issue that they are seeing quite a bit. On a new vehicle, this is an unfortunate extra $200.00 out of pocket as warranty deductible that seems more of a recallable factory defect.

The display screen just starts adjusting the navigation volume on it’s on while I’m driving. Or it will change the radio station, change to the Bluetooth on my phone or change to a different screen all by itself.This started not long after purchasing the vehicle. August 2021.
