The battery low warning notification appears when the car is driven short distances and then restarted when there is nothing apparently wrong with the battery. This is a brand new car with approximately 600 miles . We bought this make and model based on research that rated this car #1. This issue, while not safety related, is very disappointing, especially since Mazda knows there is an issue and has issued a technical bulletin, but not a recall to correct the problem. The car unlocks when the fob is within 3 meters of the vehicle, according to information provided by Mazda, so even if you lock the car and walk away it may unlock automatically causing electronics to work in the background draining the battery.
