Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
The infotainment display screen on my 2020 Mazda CX-5 has suffered a severe hardware failure resulting in un-commanded inputs, commonly known as "ghost touching." While driving at highway speeds, the touchscreen constantly registers phantom touches. It actively hijacks the vehicle's computer system and cuts out my Apple CarPlay connection during trips. This morning, the ghost touching randomly turned the Apple Maps navigation volume up to the absolute maximum level without warning. This intense, sudden noise causes driver shock and distraction while in motion, creating an immediate risk of a wreck. The vehicle currently has fewer than 29,000 miles.
The vehicle infotainment system including the touchscreen display and Connectivity Master Unit malfunctioned. The touchscreen operates without driver input, the system freezes or glitches, audio activates unexpectedly, and phone functions behave erratically. The vehicle and components are available for inspection upon request. While the vehicle was being driven, the system initiated actions without driver input including unintended phone calls including calls to 911, sudden unexpectedly loud radio or audio volume, screen freezing, and loss of navigation. These events caused driver distraction and a startle effect while the vehicle was in motion, increasing safety risk to vehicle occupants and others on the road. The issue is ongoing intermittent and reproducible during normal driving conditions. The vehicle was presented to an authorized dealer multiple times. A software update was performed in an attempt to correct the issue, but the condition continued. The dealer advised that replacement of infotainment components such as the CMU or display may be required. The vehicle has been inspected by an authorized dealer on multiple service visits. The issue was also reviewed by the manufacturer customer experience case management team which acknowledged understanding of the malfunction but declined repair assistance. No police or insurance inspections have occurred. No warning lights or messages appear before the malfunction. Symptoms occur without warning and include random touchscreen activation, system freezing or rebooting, unintended phone dialing, and unexpected loud audio. The issue began after purchase and has continued despite repair attempts. Similar infotainment malfunctions including ghost touch behavior, screen freezing or rebooting while driving, unintended audio behavior, and dialing issues have been documented in manufacturer service bulletins affecting comparable vehicles, indicating this issue is not isolated.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
While driving on the highway in traffic, I was applying the brakes (slowly and smoothly) and moving with the flow of traffic when the SBS system activated the brakes harshly and slammed me to a stop without reason. In addition to throwing me forward against my seatbelt, it also resulted in the car behind me rear-ending me. I did not hit the car ahead of me, since I was far enough behind them BEFORE the smart brake support engaged, but the feature caused an accident that could have been avoided.
The contact owns a 2020 Mazda CX-5. The contact stated that while the cruise control was activated and driving 65 MPH in the middle lane of a busy six-lane highway, the contact depressed the accelerator pedal, and the vehicle was suddenly stalled and coasted to a complete stop in the middle of the highway. The contact was able to restart the vehicle to continue driving. The vehicle was later taken to the local dealer, who was unable to determine the cause of the failure and was unable to confirm that the failure had occurred. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 32,000.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
Cylinder Head has failed at 53,000 miles. Mazda has a technical service bulletin acknowledging that this is a common occurrence with this part. They have an extended warranty for the turbo engine but not for the standard engine. Looking through online forums, there are hundreds of not thousands of these issues for this model year and engine. Mazda has clearly acknowledged there is an issue and should repair these manufacturing defects that are not normal wear and tear items.
The car has signs of current recall in other Cx-5 Models. Hesitation with acceleration or driving at high speed, reduced power, not responding appropriately when accelerating or would accelerate on its own, strong smell of gas after the car has been driven and is parked. I know there is currently a recall for a gas pump failure. There is no engine light on.
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim

I did not hit the car ahead of me, since I was far enough behind them BEFORE the smart brake support engaged, but the feature caused an accident that could have been avoided.
The Smart Brake Support system malfunctioned while driving. The vehicle began shaking and lost power, requiring excessive throttle to move. The car hesitates and may not accelerate normally, creating a dangerous situation in traffic. Warning lights appeared on the dashboard and the vehicle became unsafe to operate. The issue occurred shortly after purchase and was reproduced multiple times. The dealer inspected the vehicle but refused to provide a written diagnosis or repair timeline. The vehicle is unreliable and poses a risk of sudden loss of control or rear-end collision.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
Started smelling burning oil in 2020 Mazda CX-5 non turbo with 34,000 miles. Auto shop states it is a cracked cylinder that will cost over $7,000 to repair. A Google search shows it is a known issue but Mazda has not extended the warranty for non-turbo models.
Vehicle suffering from Mazda TSB 05-005/23 Chirping noise from Transaxle on 3rd to 4th gear upshift. Vehicle diagnosed by dealership as needing new Transaxle on 17OCT25. Diagnosis stated issue started ~32k miles.

SUNROOF EXPLODING - 2020 Cx5 I've seen other reports on mazda forums happending on cx the sunroofs RANDOM normal temp in chicago IL on Halloween night
When driving at highway speeds, when there are strong crosswinds, as there are prone to be in my area, depending on which way the wind is coming from both doors will make a screeching/howling noise. This noise is very loud and extremely distracting. When it first happens it is very jarring, and depending on the wind conditions can go on for miles, making it very hard to hear anything else. I have taken the car to two dealers who refuse to fix it because they state they cannot reproduce it but it is not something that can be reproduced without specific conditions, but they are aware it exists as they have a TSB indicating how to fix it.

Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
Air bag light is flashing in the dashboard. It says passenger air bag off. Driver seatbelt doesn't always click when trying to fastent seatbelt. I have to try multiple times until it clicks.
While traveling on an Interstate highway, my passenger side curtain airbag suddenly deployed without any warning while I was driving. There was no collision or impact, there was no debris on the road, or any significant bumps in the road. There was a very loud explosive sound and then my entire passenger side was covered in blue. The sound was so loud that it left my ears ringing and left me badly shaken up. I lost all visibility out of my passenger side as all of my side windows and mirrors were obscured, and I knew there was traffic in that lane along side of me. It felt very dangerous and I had to rely on my lane change sensors to safely pull to the side to assess any damage. There was no evident sign of any impact to my car. All of the glass was intact, there were no scratches, dents or missing paint. The airbag fully deployed for no apparent reason and I was extremely lucky that I was not injured and that my reaction did not cause an accident when this happened. The car was taken to a Mazda dealership to assess, and they did not find any damage either, but said there was no mechanical error on the part of the car, so it is still unexplained. I had it evaluated by an autobody/collision shop, again no damage was determined, their scan showed a diagnostic code that there was a "circuit short to ground".

Car “died” while idling at a traffic light. It started but would not start several hours later and car was towed to mechanic. Diagnostics “determined “after several days that car needed an ECM. ECM was ordered and replaced, along with the battery. This took several weeks, in the meantime, I had to rent a vehicle. Vehicle picked up on May 29th and driven 250 miles and car sputtered, hesitated, slowing down in heavy traffic at high speeds on highway, putting other drivers and myself in a very unsafe situation. Several days later this happened again while traveling back home, again, at highway speed putting other drivers and myself in high risk situation. (This happened several times during both trips.) As I was focused on the road, I did not see if any messages were displayed. After returning home, the mechanic was informed via voice mail and again via telephone. The following morning (June 2), the car sputtered, hesitated to accelerate at low speeds and died while driving to repair shop (battery indicator illuminated as I was pulling over). Car has been towed again to repair shop.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
My car is experiencing extreme ghost screen. Also when this happens I get a lot of warning lights when nothing is truly experiencing fault. My screen will jump, change settings, reset settings,become dark on it own, not turn on at all, flip through the system causing major distractions. For instance I was driving in my car with quiet no noise then my screen jump and without warning blasted am and scared the living heck out of me while on the highway. It has called people and hung up on its own. Lights flicker and one side of my top lights don't work. My plugin have no electricity coming to them.There are times I have trouble connecting to Bluetooth.
I HAVE BEEN WARNED BY OTHER DRIVERS AT NIGHT THAT MY TAIL LIGHTS WERE OUT. MY CLOCK AND RADIO BOTH ARE MALFUNCTIONING. I JUST TOOK THE CAR FOR THE YEARLY INSPECTION AND THERE IS A MAJOR OIL LEAK FROM A GASKET. THE CAR ONLY HAS 16,000 MILES ON IT!

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
VEHICLE WAS ON A CITY STREET TRAVELING AT 35-40 MPH WHEN THE FRONT LEFT WHEEL (YOKOHAMA GEOLANDAR G91) SPONTANEOUSLY BLEW OUT DESPITE NOT COLLIDING WITH ANY OBJECTS OR ROAD HAZARDS. AS A RESULT, DRIVER SIDE CURTAIN AND SEAT AIRBAGS ERRONEOUSLY DEPLOYED AND THE VEHICLE IMMEDIATELY SHUTOFF, CAUSING DISORIENTATION AND TEMPORARY LOSS OF HEARING IN ONE EAR.
AFTER PICKING-UP A BRAND NEW CAR FROM MAZDA DEALERSHIP, I WAS RETURNING HOME USING A 3-LANE I-75 HIGHWAY, AS ALWAYS EXTREMELY BUSY. TO STAY IN THIS TRAFFIC I WAS FORCED TO DRIVE AT 70 MPH, WHICH IS THE LOCAL SPEED LIMIT. IT TURNS OUT THAT FROM THE SPEED OF 60 MPH UP, THE CAR DIDN'T WANT TO DRIVE IN A STRAIGHT LINE ON ITS OWN AND REQUIRED CONTINUOUS STEERING WHEEL CORRECTIONS. THIS CREATED A HAZARDOUS DRIVING CONDITION CONSIDERING THE FACT THAT THE ADJACENT LANES WERE PACKED-UP WITH THE OTHER VEHICLES. UPON ARRIVAL I EXAMINED THE TIRES INSTALLED ON THE CAR AND FOUND THEM TO BE M+S TOYO A36 - THE TYPE USED FOR MUD AND SNOW CONDITIONS, TYPICALLY IN COLD CLIMATES. THE IRONY IS I LIVE IN SOUTH-CENTRAL FLORIDA, THE DEALERSHIP IS ALSO IN SOUTH-CENTRAL FLORIDA, AND THE NEW MAZDA CARS WERE SHIPPED FROM THE PRODUCER TO JACKSONVILLE PORT IN FLORIDA FOR THE LOCAL MARKETS. THUS, WHILE PERFECTLY ACCEPTABLE IN MONTANA OR MICHIGAN, THIS TYPE OF M+S TIRE IS JUST DANGEROUS WHEN USED ON HOT, SOUTH-CENTRAL FL INTERSTATE HIGHWAYS. I CONTACTED THE MAZDA NORTH AMERICAN OPERATIONS (MNAO) ASKING FOR REPLACING THE TYPE OF TIRES ON MY CAR AND POINTING TO THE FACT THAT MAZDA JAPAN SPECIFIES DIFFERENT, SAFER TYPE (THREAD AND COMPOUND) OF TIRES FOR THEIR OWN MARKETS. THE MNAO ANSWER WAS IN ESSENCE: "ONE SIZE FITS ALL'. ATTACHED BELOW IS THE TRANSCRIPT OF MY CHAT WITH MNAO, MAZDA-JAPAN SPECIFICATION OF TOYO PROXES TIRES, AS WELL AS A SAMPLE OF CUSTOMER REVIEWS OF THE TIRES MNAO INSTALLS ON MAZDA CX-5 TODAY ACROSS THE USA.

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
The steering column in this car has a known defect in the steering column nut resulting in knocking/rattling/clunking. Mazda is aware of this issue and has redesigned the steering column and issued multiple TSBs for specific models, years, and even VINs. Mazda is not classifying this a a safety issue to avoid recall but if the part is to fail it can result in loss of vehicle control and a crash. The steering column is main component necessary to have control over the car and the direction it travels. I've called my dealership and Mazda corporate who both refuse to fix the issue even though my car is under an extended warranty. TSB 06-001/24 previous TSB 06-004/23.

Transmission
Reports naming the automatic or manual transmission, including shifting behaviour, shudder, slipping and transmission control modules.
From owner reports, verbatim
The contact owned a 2020 Mazda CX-5. The contact stated that while driving under 45 MPH, the TCM received a false data sensor warning, causing the vehicle to enter LIMP Mode. The contact stated that during the failure, the smart brake feature, Adaptive Cruise Control, and other unknown ADS features and warning lights were illuminated. The contact stated that the failure with the ADS system prompted the vehicle to come to a complete stop while driving 45 MPH. The contact parked and turned off the vehicle to troubleshoot the ECU after the failure had occurred. The contact restarted the vehicle, and the adaptive cruise control warning light, smart brake feature, and ADS radar features returned. The vehicle was not repaired. The manufacturer was notified about the failure. The failure mileage was 140,000.

Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.
From owner reports, verbatim
The front seats, both electric and manual powered are rocking back and forth. Upon acceleration both seats will slightly rock backwards and then upon applying the brakes they will rock forward. It's almost like whatever is holding the seats still has a defected part or a defect somewhere else. This concerns me as a safety issue, if something were to happen and if I got into an accident, aren't the seats supposed to be secured and not have any slack or rocking in them? This has happened before on my driver side seat when I had a mazda service technician look at it he confirmed it needed to be repaired. For a whole replacement seat was estimated around $4,000.00. I was fortunate at the time to where my bumper to bumper warranty helped cover some of the cost, Mazda agreed to pay for the "parts" to fix the issue and I paid for the labor, only because I was slightly over the 36,000 mile warranty that comes with Mazda. Since the repair I was told it wasnt going to be 100% and I would still have some rocking but it wasnt as bad, that occurred around the year 2022. Now, when I have a passenger the same thing occurs. Unfortunately, I'm no longer in my bumper to bumper warranty and quite frankly this seems like a safety risk that Mazda is aware of.
