2019 Mazda CX-5

The electrical system malfunctions repeatedly. The volume on the navigation will set to maximum by itself. This is alarming and poses a safety risk. It also randomly texts people detailed location information of the driver. This is a safety risk for minors and people in abusive relationships or with a PFA order. It appears to be a common problem with this car.

I developed a cracked cylinder head in my 2019 Mazda CX-5 that only had 33,000 miles on it. I lost approximately 50% of my oil in a 4 mile drive. I believed I had been leaking oil, checked the dipstick, drove 4 miles (max speed of 35 mph), smelled the burning oil, pulled over, saw smoke coming from the hood and checked the dipstick again. Losing this much oil is a safety risk with the possibility of a fire especially if driving at a faster speed and inability to have a safe place to pull over along with smoke from the burning oil causing visibility issues which at higher speeds such as on an interstate can cause a safety concern. No indicator lights/messages appeared, this was determined from seeing what I thought was oil on the ground and then checking the dipstick. Mazda is well aware of the issue. When picking up the car for the dealership after being fixed, I asked what kind of parts were used to ensure this does it happen again. The shop employee said they were “revamped” parts due to the known issue with this model and pointed out 4 other Mazda cx5s currently in the shop with the same issue getting repaired.

The side mirrors fold in and out automatically. Sometimes they will not open to driving position, leaving the driver without the ability to check them for lane changes. This is a common problem with the automatic mirrors on Mazda vehicles. I have had them repaired once under warranty, but the issue persists. The second issue is the automatic emergency braking. It has activated a few times without need or warning. I have come close to being rear-ended because of this and received negative feedback from other drivers that were following me (use your imagination).

Infotainment Issue (Ghost Touch Issue). Mazda has been experiencing problems with the Infotainment Issue (all around the globe.. I am located in Mexico. Not sure if this channel is the right way to ask for help outside the USA); in different models such as Mazda 3, CX5, etc. My Mazda CX5 is a 2019 year model with only 10,000 miles. The "Ghost Touch Issue" started just after the 3 year warranty expired. I have the extended warranty but Mazda just confirmed this issue is not covered anymore and I need to pay approximately $1,000 US Dlls to fix the issue (and only 3 months warranty... recommendation not to park the car under the sun which for me is ridiculous). This "Ghost Touch Issue is more than an annoyance. IT IS DANGEROUS. The vehicle itself says not to play with the system while driving. When the volume goes to max suddenly on the radio and channels or worse, settings suddenly change beeping with each change (this issue causes music stations to skip around back and forth, unattended phone calls, etc); and IT IS IMPOSSIBLE NOT TO BE DISTRACTED. I got involved in a "small" car accident in 2013 due to a distraction while driving due to this crazy "ghost infotainment issue" on my vehicle. Mazda is aware of this issue and issued a service bulletin for 2014-2016 Mazda 3´s to have the screen fixed for no cost. What Mazda is waiting for to fix-make a recall and fix the issue at once? As outlined before this is a Manufacturer issue and they need to get accountable of this. Thanks in advance for your follow up and attention.

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.
