There are 4 owner-reported electrical system complaints for the 2024 Mazda Mazda3in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Car gives me emergency brake warnings about imminent collision maybe once or twice a week with nothing in front of me what so ever and once even straight up just brought me to a complete halt in the middle of the road with absolutely nothing in the road. The dealership basically told me it was a known issue and that “some models are more sensitive than others” and that they will be doing nothing about it. Different models of Mazda 3s from the same year are currently being investigated for the same recalls. This definitely needs to be addressed before I get into an accident.
My Mazda3, odometer reading about 3000 miles, would not start. I have been driving normally daily, do not leave lights on or any other equipment connected when the car is off. I have not had any warning lights displayed other than startup. Monday I drove to my local CT. golf course, 20 miles from home, arrived at 9am. 5 hours later I after golf, I can’t open trunk. Fortunately I left the car unlocked. The car would not start. Road Service tried to jump battery unsuccessfully. Dragged the car onto truck-bed and transports to dealer. Service tech contacts me next day … charged battery, checked electric system and found no malfunctions. This is a scary situation when one never knows when this will happen again. Is there a solution??
