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.

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.

The contact owns a 2026 Mazda CX-5. The contact stated while driving at an undisclosed speed, the instrument cluster displayed a black screen. The contact stated that several warning lights were illuminated. The dealer was made aware of the failure. In addition, the contact was informed that the failure was a known failure of the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 930.
