I own a 2026 Mazda Cx-5 (premium plus) experiencing critical, cascading safety defects involving the vehicle's telematics and driver-assistance systems. I have video evidence of the defect. Unintended acceleration / adaptive cruise control failure: while using the Mazda radar cruise control (mrcc) with stop & go in traffic, the system silently drops tracking of the lead vehicle (the cluster icon shifts from active green to white without warning or audio alert). Failing to recognize that traffic ahead is still stationary, the vehicle commands unexpected acceleration toward stopped cars, creating an immediate collision hazard requiring manual braking. Inoperative emergency sos system: the vehicle's in-cabin sos emergency call (ecall) button is completely inoperative and malfunctioning due to internal telematics communication failures, disabling critical emergency response capabilities. These concurrent failures of active safety controls and emergency communication systems present a severe risk to public safety. The vehicle has already undergone multiple software updates and repair visits with no resolution.
