Used 2021 Mazda MAZDA3 Select Sedan AWD for Sale near St. John's, NL

I have been to my dealer 5 times with a dead battery issue. This last time I got locked out totally from my car and had to be towed to Mazda dealer. Everything went dead could not open doors, my hood, nothing. Roadside service was afraid I was locked in and could not get out which happens. Make sure you keep your phone on you at all times. I have grandkids with me a lot. This could be deadly. Mazda also tells me because I don’t drive a lot. I have been driving this way for over 50 years never had this problem with any of my cars. Mazda just charges the battery and same thing happens over and over. Instead of checking what is draining my battery. I had to buy another battery in an emergency and now was told battery contract is now void. I kept asking if I had battery replacement in my warranty never got a yes or a no. Found out this way. Where can we all complain to get results. I may call DMV.
