2019 MAZDA CX-5 Complaints

Folding side mirror will not open all the way, causing a safety concern when driving.

Had the sudden onset of strong exhaust fumes in the cabin as others have described - especially when idling at a light. Returned to dealer after having it up on a rack to find oil dripping everywhere (shield underneath prevents from seeing drops when parked) - got word today it is indeed the cylinder head assembly. How is oil running on hot exhaust not a fire concern? I had to roll my windows down for fresh air in zero degree weather the fumes were so strong inside the vehicle. On top of that the P0126 (thermostat stuck open) diagnostic code is back for the second year in a row after having the “fix” installed under warranty last year.

My engine started smoking while I was driving fast got out of car oil leaking everywhere there was a crack in the cylinder head, another few minutes of driving and the car could have burst into flames seems like it’s a common issue with Mazda cx5 a quick google search has shown me I’m not the only one with this issue, worst thing about it is Mazda refused to fix it.

At any speed over 55 miles there is a loud whining/whistling/moan at the top of the A-pillars. I have tried taping the seams as well as silicone caulk but nothing works. My daughter has the identical car and identical problem and there multiple videos on-line of the same problem. Definitely a distraction from driving safely.

Mazda ships a defective touchscreen that will degrade and eventually register phantom inputs to the infotainment system. In my vehicle, the screen was able to randomly access my settings, including for safety (blind spot monitoring) and display (driving units, heads up display, etc) and start messing with my settings. When I was using maps, the screen would randomly zoom into different spots, or change my destination, or modify settings. This was an enormous distraction and rendered the screen useless. Also, I was never sure if I stopped the car from changing settings related to vehicle safety because I can't keep my eyes on the screen while I'm driving. It was just registering random inputs all over the screen while the vehicle was in motion.

Car will whine and jerk when accelerating. Car suddenly stopped engaging in gear after it was warm. Dealer states it has internal transmission malfunction at 64k miles. Prior to the car breaking down the vehicle was taken to the dealer for a diagnostic on 12/27/23 and concerns with the whining and jerking when driving were expressed. Dealer reports that the transmission was “operating as designed”.

OIL COMING THROUGH CYLINDER HEAD ABOVE EXHAUST MANIFOLD DUE TO BEING POROUS, CAR LEAKING OIL AND NEED TO PUT MORE OIL IN EVERY OTHER DAY. MAZDA KNOWN ISSUE TSB# SA-031/21

There is a known “ghost touch” issue with this vehicle. I did not realize that until recently but the infotainment screen will randomly activate when at low speeds and/or stopped. This has caused distractions while driving as sometimes it will actually initiate phone calls on its own. Mazda has a technical service bulletin on this but has issued no recall

Power folding mirrors do not fully close or extend during wet weather. This leaves the side mirrors visibility obstructed and could cause accident. This is a known issue and a recall should be immediately issued to remedy this dangerous defective part. Mazda technical service bulletin 09-011/20

The radio/navigation/entertainment system malfunctions. The issue is known as ghosting and is a well-known issue with selected year Mazda's. Radio stations and apps will randomly skip around or the volume of the system will blare out at the highest volume startling the driver. Which has occurred multiple times in my case. The first time I reported it to the dealer, they told me there was no issue. The second time I was informed I could pay for a repair kit and installation for over $500.
