The engine is the heart of your vehicle, and when it's not functioning correctly, it can spell trouble. Common engine issues include misfires, rough idling, and overheating. These problems can stem from various causes, such as faulty spark plugs, clogged air filters, or coolant leaks. Understanding the symptoms and potential causes of engine troubles is essential for diagnosing and addressing issues promptly. A reliable braking system is vital for safe driving, so any issues in this area require immediate attention. Common braking system malfunctions include squealing or grinding noises, soft or spongy brake pedals, and vibrations when braking. These symptoms may indicate worn brake pads, damaged rotors, or brake fluid leaks. Recognizing the signs of braking system issues can prevent accidents and ensure optimal stopping power.
