Key fob accidentally left inside vehicle when exiting and all door’s automatically locked with 3 year old child inside. No recourse other than breaking window to enter vehicle as it was in direct sunlight on 80 degree day. This dangerous scenario should not be possible and needs to be fixed.

Engine oil started leaking after I noticed smoke coming from the hood of the car. No warning signs, no check engine light, nothing to indicate any issues until this occurred. Took the car to the dealership who confirmed it was a cracked cylinder head which is now being replaced.

I drive a 2018 Mazda CX5. My "infotainment system" which contains radio, phone, and GPS controls began making random unprompted selections while I would not touch it. This is an ongoing issue. The name for this issue is called "ghost touch" While the Mazda system "locks" the touch screen while the car is moving, the issue continues as soon as you come to a red traffic light. Without putting the car in park, the touch screen reactivates and the issue proceeds. This is a safety issue as it can cause distractions while driving such as sudden significant changes in music volume and it can call a random person if your phone is connected to Bluetooth. Regardless of if the car is moving or not, this causes a driver to take their focus away from the road. From a quick google search, this is a common issue. Mazda is aware of this common issue, and in fact extended a warranty to correct it in 2014-2016 Mazda 3's. However, I called Mazda USA today and they stated that it would have to be paid out of pocket for my car.

Driving down the freeway smoke started coming out of the hood of the car and into the cabin, no warnings or warning lights of any kind, got the car to the Mazda dealer to be inspected. The dealer told me it was 5 months out of warranty and would not be covered its a cracked cylinder head and oil had dripped/leaked onto the manifold causing the smoke. No smoke was coming from the exhaust so the crack only leaked oil to the outside of the cylinder head. There is no oil in my driveway so it happened that day on the road. This is a manufacturing error that Mazda won't take responsibility for.

Front central air bag did not deploy-only the side, and then for the entire side of a four door SUV, Mazda CX-5. Air bag slammed into neck and chest of driver nearly striking jugular with sharp impact. There does not appear to be any reason for side air bag to deploy, without front center deploying.

When driving I started to smell a burning oil or rubber smell inside the cabin of the car. When I stopped I could see smoke coming from under the hood. When I was able to park, I opened the hood and could see smoke coming from the engine. There were no warning lights displaying on the dash, no leaking fluid from under the car. I did not feel safe continuing to drive the car without having it seen, so I took it to the closest Mazda dealer service. After inspecting the issue I was told there is a cracked cylinder head that is leaking fluid into the engine and the exhaust and I would need a brand new engine. The service manager said this is a known issue with the 2018-2021 Mazda CX-5. Unfortunately, the warranty that would cover this expired in April 2023 (at the time of writing this, it's May 1, 2023). It should be noted that my CX-5 is only 5 years old with ~37,000 miles on it. I was told by the Mazda service manager that the car is not safe to be driven in this condition and would have to stay in their possession on their lot until I decide if I want to have it fixed.
