一般来说，汽车故障问题的发生率会随着车龄的增长和数的增加而逐渐增加。
济南奔驰汽车保养人员看到，有数据分析表明：3年以下车辆的故障问题发生率只有31.04%，而6-10年车辆的故障问题发生率会达到平均水平之上，而15年以上车辆的故障问题发生率高达180%。也就是说，随着车龄和行驶数的增加，车辆的保养并非简单的常规保养项目而已，还要有一些零部件、损耗件的定期更换。
Generally speaking, the incidence of car malfunction problems will gradually increase with the increase of vehicle age and mileage. Jinan Mercedes Benz maintenance personnel have observed that data analysis shows that the occurrence rate of fault problems for vehicles under 3 years old is only 31.04%, while the occurrence rate of fault problems for vehicles between 6 and 10 years old will reach an average level, while the occurrence rate of fault problems for vehicles over 15 years old is as high as 180%. That is to say, as the age and mileage of the vehicle increase, vehicle maintenance is not just a simple routine maintenance item, but also requires regular replacement of some parts and consumables.
1、1-4年的车龄：青少年期，除正常保养外需要注意更换一些易损耗部件。
1. 1-4 years of car age: During adolescence, attention should be paid to replacing some easily worn parts in addition to normal maintenance.
一辆车在使用的头两年是生命的期，只要进行常规保养，基本上不会有什么问题，但超过两年以后，车辆就要开始更换一些易损耗的部件了。
The first two years of use of a car are the peak period of its life. As long as regular maintenance is carried out, there are basically no problems, but after more than two years, the vehicle needs to start replacing some easily worn parts.
刹车片：车辆使用两到三年之后，就要根据行驶里程来按需要更换新的刹车片，这样才能保证车辆在比较正常的状态下运行。
Brake pads: After two to three years of use, the vehicle needs to be replaced with new brake pads as needed based on the mileage traveled, in order to ensure normal operation of the vehicle.
一般车主也会发现，当你去做维修或者保养时，也会被检查到刹车片的更换，因为它是驾驶的首道防线。根据经验，正常的行驶情况下，刹车片大概在两年左右就会磨尽了，当然准确的使用期得视驾驶者的习惯和驾驶频率而定。如果你是那种喜欢猛踩油门和猛力踩刹车的，那刹车片换的的相对勤快了。
General car owners will also find that when you go for repairs or maintenance, you will also be checked for brake pad replacement, as it is the first line of defense for driving safety. Based on experience, under normal driving conditions, the brake pads will wear out in about two years, but the exact usage period depends on the driver's habits and driving frequency. If you are the type who likes to forcefully press the accelerator and brake, then the brake pads are replaced relatively frequently.
2、4-7年的车龄：中年期，除正常保养外需更换车内橡胶类等易老化的部件。
2. 4-7 years of vehicle age: in middle age, in addition to normal maintenance, it is necessary to replace the rubber and other aging parts in the vehicle.
超过4年的车辆，打个比方就像“人到了中年”，很多零部件都会有所松动，尤其是经过长途高速颠簸的车辆。再加上一些车内的各种橡胶管的自然老化等等问题，因此不少车主往往在车开到四、五年的时候开始换车，也有一些二手车买主喜欢买这个车龄的车辆，因为会较新车便宜很多。对于一台行驶到中年期的车辆，除了常规保养外，要格外关注以下部件的保养维修：
Vehicles over 4 years old, for example, are like 'middle-aged people', and many components will become loose, especially after long-distance high-speed bumps. In addition, due to the natural aging of various rubber pipes in the car, many car owners often start changing cars at the age of four or five. Some second-hand car buyers also prefer to buy vehicles of this age because the price is much cheaper than new cars. For a vehicle that has reached the middle age, in addition to regular maintenance, attention should be paid to the maintenance and repair of the following components:
正时皮带：开了四年左右的车子要注意正时皮带是不是该换了，一般车子在行驶了7万到10万的时候，就应该送去换正时皮带，如果不及时更换，车子行驶到半途时如果正时皮带突然断裂那就不好办了。
Timing belt: Cars that have been driving for about four years should pay attention to whether the timing belt needs to be replaced. Generally, cars should be sent to replace the timing belt after driving 70000 to 100000 kilometers. If it is not replaced in a timely manner, if the timing belt suddenly breaks halfway through, it will be difficult to handle.
橡胶管：这个车龄阶段内的车辆如果不好好保养，漏黑油、漏水等问题非常容易出现。由于橡胶管的自然老化用旧，会不定期的出现故障。假如车主对车保养得好，老化的问题会比较迟一点出现，也相当于节省了一笔钱。
Rubber tube: If vehicles within this age group are not properly maintained, problems such as black oil and water leakage are very likely to occur. Due to the natural aging and aging of rubber pipes, they may occasionally malfunction. If the car owner maintains the car well, the issue of aging will appear later, which is equivalent to saving a certain amount of money.
水箱：五年左右的车辆，水箱可能会被里面的化学物腐蚀，因此有些车子的水缸开始漏水，水箱当然就需要更换了，貌似宝马水箱如果用到五年也算不错了。
Water tank: For vehicles around five years old, the water tank may be corroded by chemicals inside, so some cars' water tanks start to leak. Of course, the water tank needs to be replaced. It seems that BMW's water tank would be good if used for five years.
3、7-10年的车龄：老年期，除需再次更换易损、易老化部件外，还需维修保养变速箱等核心部件。
3. 7-10 years of vehicle age: In old age, in addition to replacing vulnerable and aging parts again, it is also necessary to repair and maintain core components such as the gearbox.
由于汽车寿命的限定，在我国，汽车一般到了10年就该退休了，如果保养得当，爱车还能健康地如期完成使命。但车子到了7年以后，就逐步进入老年期，到了这把“年纪”，那些在第三年和第四年更换的小零件，差不多该再换一次了，比如说减振器。除此之外，大部分自动变速的车子也应该在这个时候维修自动变速箱。
Due to the limited lifespan of cars, in China, cars usually retire in 10 years. If properly maintained, a loved one can still complete their mission in a healthy and timely manner. But after 7 years, the car gradually enters its old age. At this age, the small parts that were replaced in the third and fourth years should almost be replaced again, such as shock absorbers. In addition, most cars with automatic transmissions should also have their automatic transmissions repaired at this time.
自动变速箱的保养：使用自动变速汽车的车主，自动排挡车的变速箱构造比较复杂，也比较精密，在驾驶自动变速的车子时，要想在寿命期内行驶自如，保持良好状态，车主就必须多用心，让不同排挡交替使用，该做的保养一定不能省。这样可以延长自动变速箱的使用期。
Maintenance of automatic transmission: For car owners who use automatic transmission vehicles, the transmission structure of automatic transmission vehicles is relatively complex and precise. When driving an automatic transmission vehicle, in order to drive freely and maintain good condition during its lifespan, car owners must pay more attention and allow different gears to be used alternately. The maintenance that needs to be done must not be saved. This can extend the service life of the automatic transmission.
