It sounds like you're experiencing an issue that could be related to a few potential problems, such as an oil leak, a coolant leak, or electrical issues causing burning components. The smoke and burning smell could indicate overheating or a failing part. It's crucial to stop driving the vehicle and have it inspected by a qualified mechanic as soon as possible to prevent further damage or safety risks.
