Owner report 11517042 · 2023-04-14 (April 14, 2023)

Starting [XXX], through [XXX], we began receiving multiple "Critical Vehicle Malfunction" alerts (46 alert messages)via the Mazda app, including "Parking Brake Malfunction" and "Electric Parking Brake Malfunction." During this time, the vehicle experienced delayed starts and eventually required a jump-start. We brought it to the dealership multiple times to show the messages, before our 3-year/36,000-mile B2B warranty expired, but the issues were dismissed until the battery was finally replaced. At just over 36,000 miles (currently 39,646), a n…
