Engine issues refer to problems that can arise in a vehicle's engine, affecting its performance and efficiency. Common symptoms include unusual noises, decreased power, poor fuel economy, and warning lights on the dashboard. These issues can stem from various causes, such as worn-out parts, lack of maintenance, or fuel quality. Regular maintenance, including oil changes and inspections, can help prevent engine issues. If problems are detected early, they can often be resolved with minor repairs. Ignoring engine issues can lead to more severe damage and costly repairs, making timely attention essential for vehicle longevity.
