NHTSA Complaint #11710048 — 2020 MAZDA CX-30

My 2020 Mazda CX-30 has an intermittent no-start condition caused by a complete electrical failure. This occurs randomly, often overnight and after long or short trips. When it happens: The car does not respond to the key fob or ignition Dashboard warning lights are off Vehicle cannot be started, creating a safety risk if it occurs during travel or in an emergency The defect began during car's full warranty period and has persisted despite multiple service visits and battery replacement. The dealer has been unable to diagnose or correct the issue, and Mazda Corporate is aware of the defect under case Case Number 00398310. After about two years of these intermittement failures, and parasitic draws ruled out, I paid to have the Battery replaced, independently of Mazda and the battery failed yet again. Routine diagnostics have not resolved the defect Issue is intermittent and unpredictable This is a Safety Risk as the Car has failed to start when needed on numerous occasions, and has left me stranded. ALL of these Failures have occured without warning Mazda Corporate is aware and has requested dealership diagnostics. Dealership has not reproduced the problem. Issue remains unresolved as of 1/10/2026 Video documentation exists showing dealer inspection and inability to find failure source. I am submitting this complaint to NHTSA because the defect: Impairs the vehicle’s safe operation Has not been reliably repaired Represents a potential safety risk to the driver and public I request that this complaint be recorded for investigation and included in any potential recall or safety evaluation. Service records available on request Emails with Mazda Corporate als available Video of dealer inspection showing intermittent failure avaialble
