2019 MAZDA CX-5 Complaints

Cylinder failure low oil pressure and check engine light. Mazda redid cyclinder and still getting the check engine light. Mazda working on issue and having issue resolving problem.

The Cylinder head cracked and caused oil to spill out. This was inspected at Towne Mazda in Orchard Park, NY. I was driving ~50 miles when the issue occurred, and had driven approximately 40 of the 50 miles when me and my sister pulled over and noticed my engine smoking and the burning smell to be pungent. Had I not pulled over, It could have led to engine misfire and damage to other parts of my vehicle. The Dealer confirmed the need for a new cylinder head and parts, and is currently repairing the vehicle. The Component was not recently inspected by the manufacturer, police, insurance. During the course of driving, after about ~35 miles, the oil pressure light turned on. I drove roughly 5 more miles before I pulled the car over to have it towed to my Mazda dealership.

The infotainment screen is malfunctioning and acts on it own. Random parts of the screen are touched on its own creating a lot of distractions. Examples are changing of screens, settings, ending my navigation, calling contacts etcetera. This is a huge safety hazard and Mazda dealerships are charging for diagnosis for a commonly known issue, claiming the cause is unknown, despite numerous posts and threads online linking this to a screen delaminiation issue.

As I was driving home one day in February 2024, my car felt like a strong gust of wind was getting up underneath the hood of my car, causing it to pull left and right slightly. When checking the weather, wind gusts were at 5 MPH and you could barely see trees/leaf movement. I pulled off the side of the road, checked underneath the car to see if anything was dragging/missing and all was fine. As I started driving again, I then noticed my RPM's vs MPH was very strange. When accelerating, the car randomly increased up to 4,500 RPM when trying to go 45 MPH, then shifted down to 2,000 RPM's once I reached 45 MPH. But, no matter if I left my foot on the gas pedal, lifted my foot off of the gas pedal or hit the breaks, the car would not move off of 2,000 RPM's until I pressed my foot on the break all the way down to the floorboard. No lights came on at all. I took it to the dealership that I purchased it from, expressing the scary feeling of the driving the car and showing video proof of what the car was doing in RPM's vs MPH. After further conclusion, they determined that a "sensor" had gone bad. The thought that a plastic, electronic sensor going back caused my car to feel that way and put my life at risk while driving is a scary thought. Fast-forward to April of 2024, similar symptoms have come back again. Wind feeling like it's getting under my hood, causing the car to pull left and right, RPM's not matching up and now a hot engine with no warning light coming on, is questioning if it's this particular sensor again. Not to mention, I had it inspected by the dealership two weeks ago and had an oil change done to it and the dealership said "everything looks great". You should have zero thought or worry when operating your personal vehicle, but in the past three months, I have taken my car to the dealership and or a mechanic 7 times with thoughts/worries about my car. This car has now turned into a "lemon" as one would call it and I'm terrified to even start the car.

Had a constant Valve tick on cold starts and sometimes while running long periods. Oil level top offs and changes did not remedy the issue. Mechanic says it's a bad valve lash adjuster.

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).

Automatic braking system has almost caused multiple rear end accidents as it still detects cars that have left the lane after they turn. The infotainment system has dangerous ghost touches that glitch every time the car stops which has been reported for Mazdas for the past 7 years with no recall.

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.
