| Apr 2026 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Apr 2026 | AIR BAGS,SEAT BELTS | 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. | Crash: No Fire: No | Unknown |
| Apr 2026 | ENGINE,FUEL/PROPULSION SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Apr 2026 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | 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. | Crash: Yes Fire: No | Unknown |
| Apr 2026 | UNKNOWN OR OTHER | I am reporting an ongoing defect with the infotainment system in my 2020 Mazda CX-5, involving ghost-touch inputs, system freezing, and random reboots. These issues began around the second year of ownership and have progressively worsened. The system constantly registers inputs that are not being made (ghost-touch), changes settings on its own; and occasionally- reboots while operating the vehicle. This makes it difficult or impossible to reliably use essential vehicle functions such as navigation, communication, and audio controls. The issue is particularly concerning because it creates a driver distraction and potential safety risk, as the system behaves unpredictably and requires attention while driving to manage or disable unintended inputs. I reported these issues multiple times to an authorized Mazda dealership while the vehicle was still under warranty. However, I was told no issue could be found or that software updates would resolve the problem. These updates did not fix the issue. On August 9, 2025, another system update was performed under the Mazda Connect Class Action Settlement, but the problem persists. The dealership is now requiring a paid diagnostic fee before proceeding further, despite the known nature of this defect. Based on my research and widespread owner reports, this issue is commonly associated with infotainment system defects, including screen delamination and/or failure of the Connectivity Master Unit (CMU). I am submitting this complaint to document the defect and request further review, as it affects safe operation and driver attention. | Crash: No Fire: No | Unknown |
| Mar 2026 | STEERING | 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. | Crash: No Fire: No | Unknown |
| Feb 2026 | ELECTRICAL SYSTEM,SERVICE BRAKES,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Feb 2026 | POWER TRAIN | 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. | Crash: No Fire: No | Unknown |
| Jan 2026 | POWER TRAIN | 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. | Crash: No Fire: No | 140,000 |

| Oct 2025 | ELECTRICAL SYSTEM | I purchased this vehicle as a used car from a dealership. On my way home, the infotainment panel began to shout at top volume that this is the volume that navigation would be set at. The volume was so loud that it was startling, and it continued on until I had to pull over. I contacted the dealer, but they offered no assistance. The car continues to control itself at the panel ferning with the use of android auto so that you can't use your phone GPS for directions. The radio will control itself, changing stations, making loud beeps, and turning the volume up. There is no way to stop this feature because you can't turn the system completely off while the car is on. I can find no way to fix this on my own. I have tried resets, but have seen ample information about other people having this problem online. This does not seem to be an unknown problem and I don't know why there has not been issued a recall because it's very dangerous. | Crash: No Fire: No | Unknown |
| Oct 2025 | POWER TRAIN | The issue is iron is depositing in the transmission due to a bad torque converter, this is a known issue with mazda and it doesn't seem to be something they are willing to cover and many people are experiencing this especially with the cx5 models. It causes jerking and chirping noise, plus will eventually ruin the transmission and will cause serious safety issues. Just look into the reddit threads | Crash: No Fire: No | Unknown |
| Sep 2025 | POWER TRAIN | Driving about 20 to 35 mph accelerating I would get a distinctive one time chirp noise with a little bit of a stutter It happens every time I go about that speed accelerating. Thankfully my car was under pre-owned warranty but I have to get now. Three transmission flushes I have to pay $400 for and they have to replace a torque converter. I just got the car 10 days ago and only has 61,000 mi on it. Over the long term this could damage the transmission cause more and more issues | Crash: No Fire: No | Unknown |
| Sep 2025 | UNKNOWN OR OTHER | The ongoing “ghost touch” defect in Mazda infotainment systems is a serious safety hazard that should have triggered a recall. This issue affects vehicles from model years 2016 through 2023 and stems from a design flaw present from the beginning. While driving, the system can suddenly take control of the screen—changing settings, switching stations, adjusting navigation, and even blasting the volume to maximum without driver input. On multiple occasions, I have been driving at freeway speeds when the system suddenly raised the volume to its highest level, jolting me and creating a dangerous distraction that nearly caused an accident. Mazda previously settled a lawsuit regarding this defect but only offered a free software update as a remedy. When I visited a dealership, I was told I already had the latest update—and that it does not resolve the ghost touch problem. The dealership acknowledged that it is a known design flaw, yet Mazda is charging customers around $800 to replace the defective component. This defect is widespread across multiple model years, worsens with time, and compromises the safe operation of the vehicle. Despite owning my Mazda outright and having only 40,000 miles on it, I may be forced to sell it because the vehicle has become unsafe to drive. I have a video of some of the things it does but it won’t let me upload it below. | Crash: No Fire: No | Unknown |
| Sep 2025 | ENGINE AND ENGINE COOLING,VEHICLE SPEED CONTROL | 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. | Crash: No Fire: No | 32,000 |
| Aug 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | While driving my vehicle the systems sensors are affected by nearby drivers which cause the car to stall in the middle of traffic going between 40 and 75 miles per hour. | Crash: No Fire: No | Unknown |
| Aug 2025 | AIR BAGS | 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". | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER | Display screen (Infotainment system) will randomly change the settings of my vehicle and call people or change display features or volume control or directions that is distracting and dangerous to me as I drive. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | The infotainment screen in the vehicle suffers from Phantom/Ghost touching, rending a safety hazard as while following navigation it can act on it's own, becoming a large distraction. | Crash: No Fire: No | Unknown |
| Jul 2025 | UNKNOWN OR OTHER | Mazda has a known issue with their infotainment system and ghost touch. There was a recent lawsuit but ghost touch is not covered under the class action lawsuit. The screen will call people, change setting, and just click a bunch of things. This is extremely distracting when driving if I’m constantly having to fight to stay on my navigation screen and make sure it is not calling people. It’s a very well known issue that Mazda will not fix it and quotes around $500-700 to fix with a part that will eventually have the same issue. I have tried pleasing with Mazda and basically been told too bad. I just want my screen to work and not have to fight it constantly | Crash: No Fire: No | Unknown |
| Jul 2025 | ENGINE | I noticed an oil leak. I had it diagnosed and its a crack in the cylinder head, right above the exhaust manifold. This is known issue for Mazda's online. There is oil spilling everywhere. The oil burns off as it is driving. Smoke fills my car. | Crash: No Fire: No | Unknown |
| Jul 2025 | ELECTRICAL SYSTEM | I own a 2020 Mazda CX-5 equipped with the Mazda Connect infotainment system. The touchscreen display malfunctions regularly by randomly selecting menu items, jumping between screens, zooming in and out, and activating functions without any input from me. These “phantom touch” events occur even when the vehicle is in Drive, which means the touchscreen should be disabled — yet the system behaves as if it’s receiving constant false touch input. When this happens, I cannot back out of screens or use the physical control knob or buttons, making it extremely distracting and unsafe while driving. The dealer initially diagnosed it as a screen laminate issue, which they said isn’t covered under warranty. However, this appears to be a known defect in the CMU (Connectivity Master Unit) that Mazda has not properly addressed in many cases, even though there is an ongoing class action settlement about it. The CMU passed their diagnostic test, but the issue persists — and others have reported receiving full replacements despite passing those same tests. Mazda refuses to escalate or repair unless the screen kit fails first. I believe this is a defect affecting driver safety, especially since it continues while the vehicle is moving. | Crash: No Fire: No | Unknown |
| Jul 2025 | POWER TRAIN | The contact owns a 2020 Mazda CX-5. The contact stated that the vehicle jerked abnormally while depressing the accelerator pedal. There was no warning light illuminated. The vehicle was taken to a dealer where the vehicle was diagnosed with transmission failure. The manufacturer was notified by the dealer about the failure, and the manufacturer agreed to partially cover the cost of the repair. The vehicle was not repaired and remained with the dealer. The failure mileage was approximately 52,000. | Crash: No Fire: No | 52,000 |
