Ford Fusion burning smell, check engine light on, sputtering and no acceleration, possible coolant issue on Ford Fusion

Some Ford Fusion owners report experiencing a burning smell, check engine light illumination, sputtering, and lack of acceleration, which may indicate several underlying issues. These symptoms could suggest a coolant leak, potentially leading to overheating and severe engine problems. Additionally, the check engine light may activate due to various factors, including leaks in the exhaust manifold or sensor malfunctions, such as with the O2 sensor. Owners also note that sputtering and a lack of acceleration can stem from engine misfires, fuel system complications, or exhaust system issues. It is crucial for owners to promptly diagnose these problems by checking for coolant leaks, inspecting the exhaust system, and addressing any engine or sensor-related concerns to prevent further damage and ensure safe driving conditions.
