NHTSA Complaint #11676624 — 2020 MAZDA CX-5

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.
