The vehicle's battery has gone dead on several occasions since replacing the OEM battery. The OEM battery which was approximately 3 years old, also had gone dead, prompting its replacement. The battery has gone dead within 1-2 days of not using the car. Charging the battery by running it is only a temporary fix as the car needs to be constantly driven in order to charge the battery, which is not usual and customary for the maintenance of a vehicle. This cannot be functioning to manufacturer's specifications, as I find it extremely difficult to believe that manufacturer's specifications stipulate to drive the car with more frequency. This is a safety issue. Should this happen during the winter months, an individual may be left stranded. The NHTSA must demand Mazda to issue a safety recall to fix this safety issue.

When trying to start the vehicle it is unable to start and the car chimes while the complete instrument cluster flashes off and on. The car will not start and the entire instrument panel blinks/flashes displaying all warning lights. I hear whirring and clicking noises. Just prior to it not starting I may experience the driver side vents pushing out hot air while the passenger side is pushing out cool air. I have the AC set to cool at 60 degrees both sides. I have 16k miles currently and the non start flashing instrument panel all started after Mazda did a recall and flashed the cars computer. The first problem was in April of 2020. The cars computer has been flashed more than 2 times. I have to jumpstart the car in order to start. Mazda has not found the problem and cannot recreate. The problem usually happens after the car is parked and in the sun.

The smart brake system is malfunctioning. The car slams on its brakes for no reason. No vehicle is ahead of me. I have been driving at highway speeds when this occurs and I haven't been rear ended yet. It's happened numerous times before and after I completed the recall. The condition is worse when it's raining. The car has been at the dealership for over 30 days unable to repair.

My car suddenly made a big clunk noise and I was warned of a power steering malfunction. I have also been warned multiple times that due to a malfunction the 'safety systems have been disabled', another issue in having is a headlight malfunction. When the headlight malfunction occurs the digital speedometer gets very dark and I am unable to tell how fast I am going. There is no way to turn the brightness up to see the speedometer again until the error code goes away. Mazda told me I must leave my windows down when the car is in a hot climate to prevent it from overheating while not in use...I live in Ohio so the weather is not extremely harsh. I've take the vehicle to the dealership multiple times and they have not fixed any of the issues. I called Mazda corporate and was told 'what would you like me to do about it' I was told my issues had no remedy. The corporate call center would not put me through to anyone else for further help. I feel unsafe in my vehicle and it's not even over 8500 miles yet.

The entire vehicle safety system malfunctions at random times while driving, most recently on the highway. The dashboard illuminates stating "safety and driver support systems partially disabled, drive safely". I lose blind spot monitoring, lane keep assistance, radar, and city brake support, among other things. This has happened several times over the past 2 weeks.
