I have taking it to a Mazda Dealer to be fix 4 times and they don't seem to be able to fix it.The battery was replaced.twice one by me and the second time by the dealer in an attempt to solve the problem at some point. Unfortunately just yesterday it happened again it had to towed to the Mazda dealer again for the fifth time. I really hope a solution can be found.

The car's battery has failed two times. The second time is after the battery was replaced -- so the problem was with two different batteries. Both times, I had to call & wait for roadside assistance. Dangerous situation. Both times, the car required a jump-start then a full charge. The dealer denies a battery problem or electrical system problem. However, a Mazda Roadside Assistance service provided advised me on 12/3/2022 that the (second) battery was dead and that something in the electrical system is clearly draining the battery. The car is driven every day. *** Several times a week there is a dashboard notice of "low battery risk". *** This has been consistent, starting with the first week of owning the car. It appears that something(s) in the electrical system is draining the battery to the point of failure. The car is 18 months old with @ 16,500 miles driven. It is a 2021 Mazda CX-30 Turbo Premium Plus. It is available for inspection.
