In December 2018, I bought a brand new 2018 Mazda 3. I love it and it's a great car, except there's one problem. The damn thing dies if left alone for more than 48 hours. The first instance happened in July, where I got in the car on a warm Monday morning to find that it would not start. I had left the car alone since around 3:40PM on Friday afternoon, had a lazy weekend where I never drove anywhere, and the battery apparently died in that time. I called Mazda roadside assistance and they jumped the car and everything was fine.
Now this morning, the same thing happened. I got out of the car around 4PM on Friday, and now on Monday morning it's dead again. In December I actually went and bought a new battery from Costco since my dad said the one it came with was so weak, and yet it still died after 48 hours of inactivity. So now, as I sit here waiting for the jump again, I figured I'd ask you folks since I don't know much about cars. It's still under warranty, so I might have Mazda take a look at it.
It's worth noting -- I have a dashcam plugged into the cigarette lighter, and I believe it continues running even when the car is off. But I can't imagine it's drawing that much power that it sucks the entire battery dry in two days. Am I off base here?
