Electrical issues are another area to watch out for. Modern vehicles, like the GL400d, rely heavily on electronic systems. Problems can arise with sensors, the infotainment system, or other electronic components. Regular diagnostic checks can help identify and address these issues before they become major problems. Finally, like all vehicles, the GL400d is subject to wear and tear on components such as brakes, tires, and suspension parts. Routine maintenance, including replacing worn parts when needed, is essential to ensure the vehicle's safety and performance. Being proactive about maintenance and addressing issues promptly will keep your GL400d in top condition, ensuring many years of reliable service.
