At this point, the vehicle has passed the break-in period, and all components have been fully exercised. This is the peak performance stage of the vehicle, but some sealed-cycle oils and fluids are typically replaced around this time, commonly referred to as a "major ." The maintenance tasks include changing the engine oil, oil filter, air filter, fuel filter, and other routine services. Key items in a major maintenance: Besides replacing the engine oil and oil filter, there are two additional key projects in a major maintenance: 1. Air filter: The engine ingests a large amount of air during operation. If the air is not filtered, dust particles can accelerate wear on the piston group and cylinder. Larger particles entering between the piston and cylinder can even cause severe "cylinder scoring." The air filter's role is to remove dust and particles from the air, ensuring sufficient and clean air enters the cylinder. 2. Fuel filter: The fuel filter provides clean fuel to the engine by filtering out water and impurities from the gasoline. This optimizes engine performance and offers the best protection. Typically, during vehicle maintenance, technicians will conduct additional inspections based on the car's condition and may add other maintenance tasks, such as inspection and cleaning of engine-related systems, tire alignment checks, inspection of fasteners, etc.

Last time I took my Sportage for a 40,000 km service, and the whole process was quite straightforward. First, they changed the engine oil and oil filter, which is the most basic procedure to keep the engine running smoothly. Then they checked the brake pads and discs to ensure responsive braking—safety always comes first. The air filter was also replaced to prevent dust from entering the engine. The spark plugs needed changing too, as worn-out ones can increase fuel consumption. I remember asking the mechanic to inspect the suspension system and tighten the chassis bolts to prevent vibrations. Finally, they topped up the coolant and gave the car a wash. Now it drives as smoothly as a brand-new car. I’d recommend everyone to stick to regular maintenance schedules—don’t procrastinate. Proper upkeep extends your car’s lifespan and gives you peace of mind. Spending a bit more on maintenance now is far more cost-effective than major repairs later.

My Sportage has run 40,000 kilometers, and there are key points to note. The engine oil and filters must be replaced to avoid engine wear; check the brake system and tires, as the tires may be worn out and need replacement. Replacing the spark plugs can save fuel, and the brake fluid should be topped up properly. Tighten the chassis screws to prevent loosening, and inspect the suspension system for any oil leaks. Also, test the battery voltage to avoid getting stranded on the road. I prefer using genuine parts and visiting authorized service centers, as they have professional equipment for inspections. After maintenance, the car responds much better, and fuel efficiency improves, making it worth the time and effort.

Maintaining the Tucson to 40,000 km, the key to saving money is focusing on the essentials. Don’t skimp on changing the engine oil and filter—it’s crucial for engine health. However, just inspect the brake pads; if they’re not thin, don’t replace them unnecessarily. You can replace the air filter yourself— online is cheaper. Check the spark plugs’ lifespan; if they’re still good, hold off on replacing them to save around 200 yuan. For the chassis and suspension, a quick check on bolt tightness is sufficient. Opt for mid-range priced engine oil brands—no need for premium. I recommend visiting reputable independent repair shops, where prices are 30% lower than dealerships, but ensure they use qualified parts. This maintenance approach cost me under 1,000 yuan, with equally good results.

At 40,000 kilometers, maintaining my Sportage is a major safety priority. Essential oil and filter changes keep the engine running smoothly to prevent malfunctions. A thorough brake system inspection ensures responsiveness: pads, discs, and fluid must all be checked to avoid high-speed failures. Tire pressure and wear patterns require meticulous examination—replace immediately if uneven wear is detected. Suspension components should be inspected for oil leaks, and chassis bolts must be properly tightened. Don’t overlook brake fluid top-ups to prevent failure. I emphasize that safe driving hinges on these measures—never compromise safety to save small costs. After , test-drive cautiously to verify brake performance, ensuring zero hidden hazards on the road.

My daily-driver Sportage has hit 40,000 km, so maintenance needs to fit around life. When work gets busy, I book afternoon appointments – oil and filter changes are done in a flash. I always ask the mechanic to check brakes and tires while I'm there, avoiding weekend trip surprises. The cabin air feels noticeably fresher after replacing the air filter. New spark plugs added some pep to my commute acceleration. Topped up coolant as prevention against overheating too. Post-maintenance, the car runs like an old friend – before any road trip, this thorough check gives me peace of mind without the hassle.
