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.

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.

The failures are intermittent but recurring, and I have personally experienced them multiple times under normal driving conditions. The dealership has not been able to reproduce the failures consistently, and Mazda has provided no inspection, no investigation, and no acknowledgment of the issue despite multiple attempts to contact them. In addition, numerous other 2026 Mazda CX‑5 owners are reporting the exact same problems across multiple online forums and owner communities. These include: • Complete center display blackouts • Random system errors • Telematics failures • Driver‑assist malfunctions • Connected Services not working at all Owners are actively seeking help from one another because Mazda is ignoring customer reports, providing no guidance, and offering no official communication or support. This widespread pattern strongly suggests the issue is not isolated, but rather a potential systemic defect affecting the 2026 CX‑5 platform.
