There are 4 owner-reported electrical system complaints for the 2024 Mazda CX-30in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The vehicle intermittently fails to start when pressing the push-button start system. The start/stop button becomes unresponsive despite normal conditions (key present, brake engaged, no warning indicators preventing ignition). This has now occurred twice within two years of ownership, indicating a recurring issue rather than an isolated incident. On the most recent occurrence, the vehicle was completely unable to start and required towing. The tow truck operator reported that he had towed four vehicles of the same make/model for the exact same issue within one week, suggesting a broader pattern affecting multiple vehicles. Safety Concern: This presents a significant safety risk, including: •Inability to start the vehicle in unsafe or emergency situations •Risk of being stranded in dangerous environments (e.g., roadside, extreme weather, unsafe areas) •Potential failure of the ignition system, which raises concerns about reliability of vehicle operation overall A malfunction in the start/stop system directly impacts the vehicle’s basic functionality and creates an unpredictable and potentially hazardous situation for drivers. Additional Notes: Given the repeated occurrence and reports of similar failures in other identical vehicles, this issue may represent a systemic defect that warrants investigation.
I was sold this 2024 Mazda cx30 from Ken ganley kia located in mentor Ohio (44060) the vehicle started showing major electrical issues. when they occur I have no control of the functions of anything in the cabin (infotainment, heat/air, braking system,) just to name a few. My wife and I were assured we were purchasing a good safe and reliable used vehicle. I feel this vehicle is extremely unsafe and unpredictable and ken ganley kia of mentor refuse to take this unsafe vehicle back or even pay for the repairs. I am utterly disappointed such a big name in the auto industry could turn there back on a customer not only that let a young family pull off in a unpredictable electrical nightmare of a vehicle and refuse to stand by it.
