I haven't slept well in the past 5 months because of this check engine light. I've taken my car to the dealership several times, and they've given me various explanations, including a software update, the need for routine maintenance, and eventually, an ignition problem. Despite their attempts to address the issue, the check engine light keeps reappearing. I'm at a loss and don't know what to do next. It's frustrating that the dealership seems unable to diagnose and solve this issue!!
