Touch Screen and/or infotainment center causing ghost touch. Available for inspection. Ghost touch (known Mazda issue) with touch screen has been changing radio stations, increasing volume to max. Will go into user settings and change guidance voice to full volume, increasing bass to full volume, fast forward songs, mute phone call feature, randomly switch from bluetooth to handset of phone. All of this is done without the driver or anyone else in the car touching anything. When this happens there is no easy fix. I cannot just stop the song, mute the volume. We have to wait for it to decide to stop and fix itself. It is a safety issue because You are driving and randomly volume goes to full blast an startles you, cannot hear what is going on around you, and hurts your ears. This is distracting and I have swerved my car because of it. Bluetooth capability is suppose to be handsfree, so if it keeps muting my call or switching to my phone, that is now a safety hazard as well. vehicle was inspected in 2021 by Mazda dealership. At that time they said the only thing they can do it remove the SIM card, and we would lose navigation. However the issue did not stop. It would cost us about $1000+ between labor and parts and inspection to get this fixed. It was addressed again in 2023 and 2025. 2025, when the infotainment system had a class action law suit but ours wouldn't be covered because its the touch screen and not the computer. No warning systems.

The cylinder head on my 2018 Mazda CX-5 developed cracks on the exhaust side, leading to significant oil leakage onto the exhaust manifold. This has caused engine damage and safety concerns. The vehicle is currently at a Mazda dealership, where the issue has been inspected and documented. The component is available for further inspection upon request. The oil leaking onto the exhaust manifold creates a serious fire hazard due to the high heat generated in this area. Additionally, the vehicle experienced burning smells and visible smoke coming through the air vents, which could impair visibility or cause distraction while driving. These conditions place the safety of myself, my passengers, and others on the road at risk. The issue has been confirmed by a Mazda dealership. They provided a video showing oil actively dripping from the cracked cylinder head and stated that the engine requires a full replacement. Mazda dealership video: [XXX] This video contains the engine inspection findings conducted at the dealership during my recent visit. It clearly shows the damage and highlights the issues identified. The vehicle has been inspected by the Mazda dealership service team, who identified the cracks in the cylinder head and documented the oil leakage and related engine damage. There were no warning lamps or messages on the dashboard prior to the failure. The symptoms began with a noticeable burning smell inside the cabin, followed by a slight mist coming out of the air vents and smoke from under the hood. Oil leakage was later observed on the ground, and the coolant level appeared empty. I’ve received a video inspection of my vehicle from the service center on March 7, 2024 with no concerns at that time, which you can view here: [XXX] .
