2026 Mazda CX-5 Problems

I leased a brand new vehicle on June 8th. On June 12th, I took it to the dealer's service center because of a warning message, accompanied with a loud chime that said: "Emergency Call Unit Malfunction", the SOS red light was also on. I picked the car up today, June 15th. Shortly leaving the dealership, I was driving on the freeway crawling traffic with my husband and 4 year old child in the vehicle. Suddenly, the service/wrench icon started flashing on the dashboard, and the car's engine completely died and stalled while we were moving on the highway. At the exact second the engine died, dash and infotainment screen went completely black, the A/C shut off as well. I instantly lost my speedometer and all safety alerts while stuck in traffic. I was still stepping on my brakes, and turned my hazard lights on so we could pull over to safety. Screens went back on and engine came back on. We were fortunate to be by the nearest exit and took it. The screens went back on, but service light was still flashing. We were able to drive the car to Mazda, and was provided a loaner car. This is a massive safety issue and hazard that put my family in immediate danger on a busy highway just following a dealer service.

The vehicle's Automatic Emergency Braking (AEB) / Smart Brake Support system intermittently triggers "false positive" emergency braking events during critical driving maneuvers, specifically while accelerating to merge into highway traffic. During these events, the system violently applies the brakes with no external hazard present. Crucially, the vehicle fails to acknowledge driver override input. Depressing the accelerator pedal fully does not disengage the automatic braking, stripping the driver of vehicle control and exposing the vehicle to a severe risk of being rear-ended at high speed. Simultaneously, the vehicle experiences a persistent "In-Unit Telematics Malfunction" error on the dashboard, accompanied by rapid-fire mobile app notifications (14 alerts in a single day) stating "Critical Vehicle Malfunction: Vehicle cannot be driven." These communication module errors have persisted despite the dealership applying Mazda's latest software updates, indicating a critical network failure or hardware defect that compromises active safety systems.

Have a cracked windshield from a chip near the wiper area Mazda says needs to be replaced But they are on National back order Was told that when the windshield caves in or collapses Then an emergency order can be put in

The windshield of my 2026 Mazda CX-5 suddenly fractured and developed a severe crack without any external road hazard or heavy stone impact. Under micro-photography, the root of the crack presents as a smooth, continuous stress fracture ("white line") with no physical crater or concentric shattering pattern. The authorized Mazda dealer and Safelite AutoGlass provided entirely contradictory diagnostic locations regarding the alleged "impact point," proving the source of the failure is highly ambiguous. On this vehicle, a standard, everyday micro-pit from normal road dust triggered a catastrophic structural fracture across the glass. This is a disproportionate failure indicating excessive internal manufacturing residual stress or structural pressure from the vehicle frame rather than owner wear-and-tear. Furthermore, this severe fracture directly obstructs the driver's forward vision and threatens the calibration and safety functionality of the i-Activesense forward-facing safety cameras mounted behind the rearview mirror, creating a sudden, severe driving safety hazard.

The contact owns a 2026 Mazda CX-5. The contact stated that while attempting to start the vehicle, the infotainment system failed to operate as intended, and unknown sensors were illuminated. No warning light was illuminated. The vehicle was taken to the dealer; however, the diagnostic result was unknown. The failure had occurred on several occasions. The manufacturer was not notified of the failure. The approximate failure mileage was 300.

About a week ago, a "telematics error" message displayed, a single red light on the SOS button turned on, and it started beeping loudly. This has repeated multiple times. In this state the vehicle cannot automatically summon emergency help following a crash, and I cannot manually trigger an SOS call. More recently, June 17th, a new symptom has occurred. Vehicle's touchscreen display would not turn on. This display is required to access heating/cooling features including defrost/defog, and is used to show the backup camera. The dealer has informed us that these issues were all caused by a manufacturer-initiated over-the-air software update. We are currently scheduled to have a new software update installed to replace it on June 22nd.
