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.
ELECTRICAL SYSTEM06/10/2026
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.

Read windshield just shattered while driving down the highway. No object hit the windshield. On I-95 near PHL airport, near exit for Rt 420
ELECTRICAL SYSTEM,UNKNOWN OR OTHER04/16/2026
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.
AIR BAGS,SEAT BELTS04/08/2026
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.
ENGINE,FUEL/PROPULSION SYSTEM04/08/2026
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.
SERVICE BRAKES,FORWARD COLLISION AVOIDANCEcrash04/07/2026
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.
UNKNOWN OR OTHER04/01/2026
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.
STEERING03/16/2026
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.
ELECTRICAL SYSTEM,SERVICE BRAKES,ENGINE02/23/2026
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.
POWER TRAIN02/17/2026
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.

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.
