There are 3 owner-reported electrical system complaints for the 2025 Mazda CX-5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I purchased this vehicle new in June 2025. About a month after the dealer service inspection, the vehicle suddenly would not start at all. The key fob sometimes cannot unlock the door, and I have to use the backup key to open it. After entering the vehicle, the engine will not start. I previously brought the car to the dealer for inspection, but they said no issue was found. Now the problem has happened again and the vehicle cannot start. This is a serious reliability and safety concern for a new vehicle.
Critical Malfunction- causing parking brake malfunction, anti lock brake system malfunction, Dynamic stability control malfunction, Disabled blind spot monitoring, Keyless entry system malfunction, Front brake / and obstruction warning disabled, Keyless entry system malfunction, Air Bag system and seat belt pre-tensioner system malfunction. Vehicle not starting./dead. Sat at dealership service where purchased for 6 days saying they could not test bc they did not have a battery tester- Magically when I complained they found one- and say everything checks out ok. Vehicle is not safe!!!! If this malfunction happened while driving I could have been killed. The dealership refuses to anything g but say it’s OK- and it’s not a lemon. I cannot put my life at risk and they will not guarantee it will not happen again- or say why it happened- other than check g the battery.
