Vehicle warranty period includes: replacement of air filter, oil filter, spark plugs, brake linings, and clutch plates. The vehicle warranty period refers to the time period during which the car manufacturer promises to provide free repairs and for faults caused by quality issues when selling the product to consumers. The warranty period for cars is usually 3 years or 60,000 kilometers, whichever comes first. Once either condition is met, it indicates that the car's warranty period has expired. After the warranty period, the owner is responsible for all expenses. Additionally, if the vehicle is not maintained according to regulations, or if damage is caused by unauthorized modifications or improper use, it will not be covered by free warranty even during the warranty period.

When I buy a new car, the warranty coverage is my top concern. The whole vehicle warranty generally covers 3 to 5 years or 100,000 kilometers, whichever comes first. Core components like the engine, transmission, and chassis are all included in the coverage—if there are quality issues, the manufacturer will repair or replace them for free. Electronic systems such as the central control screen and sensors are also covered. Wear-and-tear parts are more special—items like wiper blades, brake pads, and batteries usually only have a warranty of six months to one year. Damage caused by human error or failure to perform scheduled isn’t covered, and accident repairs should be handled by the insurance company. During the warranty period, it’s recommended to get maintenance done at the 4S shop to avoid disputes later.

The vehicle warranty mainly covers three major parts: the powertrain, chassis, and electronic systems. From my experience, components like the engine block and crankshaft in the powertrain are usually covered the longest, often up to 5 years. Chassis parts such as the suspension system and steering gear are also repaired for free if issues arise. The infotainment system and air conditioning compressor fall under the electronic warranty. It's important to note that consumables like tires and bulbs are typically only covered for 3 to 6 months. Modified parts are often excluded from warranty , as are natural disasters like flood damage. Always keep your maintenance records in order, as dealerships might otherwise refuse responsibility.

When I just picked up the new car, the salesperson mentioned that the warranty mainly covers manufacturing defects. For example, issues like engine oil leaks or transmission jerking due to craftsmanship. If body rust occurs during the warranty period, it can be handled for free. I specifically checked the manual, and mechanical components like the front and rear axles, drive shafts are basically covered. However, issues like leather seat discoloration or infotainment system lag would depend on specific terms. If you modify headlights or flash the ECU, the manufacturer might void related warranties. Faults caused by using low-quality fuel are also not covered.

The warranty is essentially a repair after purchasing a car. In addition to the conventional engine and transmission, systems like power steering and braking are also covered. For electric vehicles, the focus is on the three-electric system warranty, which is typically longer than that of fuel-powered cars. Components like window regulators and door locks are included, but scratches and scuffs must be handled by the owner. Recently, I didn’t have to pay for repairing a sunroof leak because it was considered a sealing design defect. However, the manufacturer won’t cover short circuits caused by high-pressure car wash sprays. Remember, the warranty period starts from the date on the invoice.

The core of vehicle warranty is to address non-human-induced malfunctions. My car's manual indicates that chassis components such as suspension arms and steering tie rods are covered for 5 years. Electronic components like ABS sensors and reverse radar modules are also included. If the fuel pump exhibits unstable fuel supply, it can be replaced for free. However, consumables like a dead or air conditioning odor filters are at the owner's expense. Damage from collision accidents is not covered. There's an additional detail: if the car breaks down during out-of-town travel, nationwide warranty service is available at authorized nearby repair shops, but original purchase documents must be presented.
