While driving, my car has stopped two times. first time I crashed on the side of road causing all of my tires and rim busted and had to replace all of them. I had no idea what was going on. second time I was taking kids to school where can just stopped in the middle of road and restarted. Recently it was smelling so I took it to dealer where they said its one of the cylinder and its not safe to drive so they replaced it as its under warranty. While my car is been with Mazda dealer I have been using their loaner car. but then received this letter of Safety recall on similar issue i had in the past and i have been trying to contact Mazda but no success. no email, chat or phone call response. I do not feel safe to drive this car which i bought in 2018, its been having lot of engine related issues. and i do not feel safe to drive this car with my kids in it. I have requested Dealer to let me keep the loner car until they fix safety recall issue. and i am trying to contact Mazda but no response please help.
