““My 2022 Mazda 3 is experiencing an ‘in-network malfunction’ related to the vehicle’s internal communication system. Multiple technicians have told me this is an internal vehicle network/communication fault, not caused by wear or damage. The dealer refuses to repair it unless I pay out-of-pocket, even though this appears to be a manufacturer defect in the electrical network system, (TCU)This malfunction affects the reliability of the vehicle’s electronics and could impact safety systems while driving. …”

“Car doesn't start if sitting more than 4 days untouched. When i went to the dealer, they informed me they know about the issue but nothing can be done about it. They even told me what the issue was, there's something in the car (they don't know what) that draws a lot of power non stop. kills the battery and some time will get stuck mid ignition. I've replaced the battery a few times as well. It's very stressful trying to deal with it after a 12-16 hour shift at work. knowing it will happened again and again, over and over.”

“Purchased the car new in April 2022. They have replaced the battery twice in the last year. They now tell me that there are no replacement batteries made for my vehicle and have acknowledged a problem with the battery made by Johnson control. The battery will not hold a proper charge after the vehicle is shut off. They have offered a loaner car but cannot tell me how long it would take to resolve the issue. In order to drive the vehicle I have to carry a jump pack in the car with me in case the battery goes dead and will not start.”
