   The infotainment display screen on my 2020 Mazda CX-5 has suffered a severe hardware failure resulting in un-commanded inputs, commonly known as "ghost touching." While driving at highway speeds, the touchscreen constantly registers phantom touches. It actively hijacks the vehicle's computer system and cuts out my Apple CarPlay connection during trips. This morning, the ghost touching randomly turned the Apple Maps navigation volume up to the absolute maximum level without…

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…

   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…

   *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,…

    I bought this 2020 Mazda CX-5 Sport 2.5L all wheel drive from a big dealership on July 31, 2023. I started having issues with EPB (electronic parking brakes) in February 2024. When I put the e-brakes on, the yellow parking brake light and the red brake light would come on. Seems like they would engage and disengage just fine except those 2 lights would stay on no matter how many times I tried turning the e-brakes off. I put a new battery in because of some research I did to…
