2019 Mazda CX-5

My wife's vehicle has a "Infotainment screen" (dashboard touch screen). There is a class action suit (CSP13d dealer letter) for issues regarding the screen performing tasks (Ghost screening touch) on its own. In lieu of a Mazda vehicle mass recall, they agreed to "FIX" the issue with a software update and replace the CMU Module of the vehicle to rectify this issue. I am here to report / advise you that MANY Mazda owners are NOT happy and have taken it upon themselves to disconnect these screens and do other "work around self repairs (removing/ disabling the unit) in order to fix the issues that occur. I have directly contacted Mazda in regards to my issues and they stat they can ONLY do what was advised on the court ordered settlement and NOTHING more to fix the issue. I want to advise you first hand, their FIX for this issue does NOT fix the problems. In fact, it is making it much worse! NOW my wife's vehicle is operating this screen by itself, WHILE driving, creating a MAJOR distraction. This "Ghost Touching" is actually going into the braking system settings and trying to change/ alter them AS she is driving! A MAJOR SAFETY ISSUE. She has had to, on several occasions, pull over /off the road, shut down the vehicle and try to "reset" what has occurred and check her system for ANY altered setting..if possible. As a retired Police Officer, I can tell you first had that if we ever encountered such thing/ safety issues reported by drivers, we would NOT allow them to travel any further with the vehicle and have it safely towed to a dealer or mechanic for repair. For their safety as well as the rest of the publics safety!! Mazda has refused to fully fix this issue and you can even see on numerous social media posts of MANY others reporting similar issues, disabling their devices on their own and doing other work arounds to mute or disable their devices totally. I Implore you to do a FULL RECALL of ALL affected vehicles to fix the problem ASAP!

I purchased a 2019 Mazda CX-5 (As is) on July 20, 2015. On September 11, 2025, as I was traveling on a three lane highway. I attempted to pass another vehicle. As I was attempting to go around the vehicle, my Mazda suddenly began braking and quickly losing acceleration. The speed limit on the highway was 70 mph. I estimated my speed at the time was between 70 and 75 mph as I attempted to pass. Pressing on the accelerator pedal did nothing. I had to try and very carefully steer the car to the right hand side of the road while trying to avoid oncoming traffic approaching from behind. When I finally got the car off the road, this is when I noticed that the car had stalled. The car started right back up and I continued to my appointment. The "radar cruise control" was activated at the time of the incident. On September 15, 2025, I contacted the dealer where the car was purchased and explained what happened. I was asked to bring the car in that same day. The car was supposedly looked over and connected to the Service Dept.'s computer to see if any error sign appeared. Nothing showed up. I service technician was then asked to ride with me to see if the car would replicated the same stalling as it has previously done. We could not get the car to stall as it had previously done. Before leaving, a salesman asked me if I wanted him to explain the "radar cruise control" to me some more. I agreed. The salesman then proceeded to tell me that "the car did not stall, it was simply braking from the activation of the radar cruise control". Being an experienced driver, I told the salesman that the car had stalled as evidenced by the fact that I had to restart it. The situation was not resolved to my satisfaction, but no other offers were made by the dealer. I requested additional diagnostic work to be done, but the dealer refused to cooperate. I did take the car to another Mazda dealer, but could get no offer but to connect the car to their computer.

When accelerating, the transmission feels jerky/stutters. The check engine light and traction control light are illuminated and on the instrument cluster the messages: "Forward Smart City Brake Support Malfunction", "Smart Brake System Malfunction" and "Front Radar Sensor System Malfunction" appear. The vehicle acts like it doesn't know which gear it should be in, it'll buck pretty hard and then it refuses to accelerate...it feels like it's in a "limp mode". A previous driver of the vehicle complained and said that it actually stalled in traffic on the highway and was of course difficult to steer due to loss of power. I took it to a dealership and they came up with a laundry list of things to fix...most of which wouldn't have any bearing on this issue. I did have the serpentine belt replaced and the belt tensioner replaced due to wear on the belt and loose tension. On 7/16/25, I scanned the vehicle with a code reader, the codes P0301 and P0506 appeared. P0301 is a generic "Cylinder 1 Misfire Detected" message and P0506 is a generic "IAC system RPM Lower Than Expected. The vehicle was taken to a shop where the spark plugs and the cylinder 1 coil was replaces and the IAC cleaned. On 7/24/25 the same vehicle behaviors were observed and the same warning lights and messages were activated. I scanned the vehicle and got "p0300 Random/Multiple Cylinder Misfire Detected and P0304 Cylinder 4 Misfire detected. There was a recall on this particular vehicle make, model and year and my vehicle was out of the VIN# range. I firmly believe that the recall needs to be expanded to include a larger number of vehicles...you can google about this vehicle and see many others with similar issues. Usually, the cure is a PCM reflashing/software update that seems to take care of the issue. Please expand the recall before someone dies in an accident because of this problem.

Good afternoon. I am reporting an incident that occurred on December 29, 2024. I was driving my 2019 Mazda Cx-5 and I was about to make a left turn. However, as I was making the left turn, I received a notification on my dashboard about a "Forward Smart City Brake Support Malfunction" (a photo of the notification will be included). My car instantly lost control and it did not stop until it collided with the street curb of the road I was attempting to turn on. Fortunately for those around me, my car did not collide with any other vehicles on the road. However, this collision caused damage to the right side of the vehicle, as the right airbag of the vehicle had deployed. I believe that this is a very significant problem that should be looked into as soon as possible. If my car were to hit other drivers on the road, it could have led to a very tragic incident. As far as repairs go, I wanted to wait and see how this complaint would carry out. I do not believe that it would be fair for me to pay repairs for an event that was out of my control. Thank you.

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).

When the system thinks there might be a collision it initiates a hard braking even when there is enough space to avoid a collision. Multiple times, the car behind me had to do a hard break as well not to hit me from behind. A google search revealed multiple people complaining of similar issue. The system brakes too extremely aggressively (drops speed from 30 MPH to 5 or less MPH almost instantly stopping/causing skidding) even at its lowest setting. When I address with Mazda Service Manager he advised "it's supposed to do that" and if I choose to I can manually disable the feature each time I enter the vehicle. Note, I am currently driving a loaner car 2023 Mazda CX-5 and have not experienced the same issue, so it does not seem "it's supposed to do that". I have been driving the loaner for 4 weeks and not once have I experience this issue - the system has never engaged except for once where only the Warning light appeared on the display but the braking did not engage. Whereas my vehicle engages this anti collision braking nearly every day I drive it. This system has almost caused more accidents than it protected me from them.

While driving down the road my Mazda CX-5 continues to just stall and the engine light turns on and the safety features turn off. I was driving down a road in town and the engine started stalling as I came to a red light and slowed the engine shut off and I was almost hit from behind. It took several attempts at starting before the car would start. This has now happened for the past 3 days and is happening more and more frequently. I do not have any other means of transportation and after attempting to get the dealership to check due to the recalls on the Mazda CX-5 for fuel pump failure and the mechanic saying it appears the fuel pump is bad the dealership refuses to attempt any repair because the VIN is not listed in the recall at this time. This is a severe safety problem because if it stalls in traffic I will be in an accident as I have no ability to maneuver the vehicle when it stalls to get out of the way of vehicles approaching. If this issue isn't resolved it is going to cause injury to myself or others. People have had to swerve into the path of other vehicles to keep from hitting me when it stalls, which is eventually going to result in harm to others and/or myself and family.

The 2019 Mazda CX-5 has a design and manufacturing issue with its infotainment system. The screen activates functions without pressing the screen or activating the joystick. It changes the station, calls by phone and changes important security parameters such as braking assistance. Reflecting a notice on the main board. There are thousands of cases of affected vehicles. This problem is a serious situation that Mazda must correct immediately, because it distracts the driver and changes extremely important safety parameters. The infotainment system is not just for listening to music or making calls. This system manages many aspects of vehicle safety. Mazda replaced the part with a new part number for obvious reasons. All vehicles that have the affected part must be replaced with the new part number to avoid possible accidents. The defective part is K123-61-J0A. The replacement is K123-61-1J0C. Thank and best regards.
