Some 2020 Land Rover Discoverys produced between September 13, 2019 and November 21, 2019,* **Total 13 vehicles.

The above content is a summary of the recalled models in 2020 by Real Vehicle Network. In 2019, my country's automobile market initiated 170 recalls, involving 56 brands. A total of 6.8097 million defective cars were recalled. Compared with last year's decline of 48.3%, the recall scale has returned to less than 10 million vehicles. As China's automobile market becomes more mature, the scale and number of automobile recalls are stabilizing. This also shows that the quality of cars made in China is getting better and better. It is undeniable that policies and mechanisms such as vehicle recalls and refunds and compensation are effectively restraining car companies. But recall after recall is a huge loss to car owners.

The number of automotive complaints increased by 25.1% in 2019

1. There are many product quality problems, and most of the complaints from car owners are concentrated on auto parts, such as engines, gearboxes and other major components. Current fault

2. Car purchase contracts are highly controversial. This problem occurs every year. Basically, the contract signed by the operator is obviously beneficial to the operator, or even violates legal regulations and excludes the main rights of consumers. The terms of the contract are unclear and unequal in terms of rights and obligations between consumers and sellers, and the liability for compensation after breach of contract is unclear. Consumers cannot effectively safeguard their rights in accordance with the contract.

3. After-sales service problems, the dealer cannot repair the fault at once, but repairs it repeatedly, and does not issue details during the repair.

4. It is difficult to test and provide evidence to protect rights. Once a car has quality problems, it is really difficult to verify, seek appraisal, and seek compensation.

5. Bundle sales of car insurance and induce consumer loans. Everyone who buys a car knows that if you don’t buy it in a store, you won’t be able to enjoy any preferential policies. What’s more, consumers are sometimes required to pay an insurance deposit ranging from several thousand to tens of thousands of yuan.

6. The information on second-hand cars is untrue. There are too many problems with second-hand cars. Generally, operators conceal the truth about sales. In order to make money, they do not fulfill their obligations of true disclosure, whether online or offline, and even change the mileage privately. The phenomenon of concealing the true condition of vehicles, describing flooded cars as having no flooding, and describing cars that have been involved in major accidents as having minor bumps.

Finally, let’s talk about the warnings the 3.15 Party has given us over the years, and what other invisible problems

Why should I talk about this at the end? I just want to warn car owners that there are some daily car problems that we need to learn in advance and prevent in advance, so as not to cause more trouble to ourselves.

Increased engine oil

This problem happened last year, and it has come again this year. I will explain to you what causes the increased engine oil. First of all, increased engine oil and oil emulsification are two different things. , here we first talk about why direct injection engines love more oil. We can see from big data that most new cars have an increase in oil in the north. In winter, direct injection engines are prone to wet wall phenomena in the cylinder. Coupled with low temperatures, plus Traffic jams and short-distance driving prevent the fuel that has penetrated into the crankcase from evaporating completely. It mixes with the engine oil, causing an increase in the engine oil. When you pull out the oil dipstick, you will find the engine oil. In addition, you will smell a smell. The pungent smell of gasoline is basically the reason.

Many people don’t understand low-temperature short-distance working conditions. Let me explain it to you. For example, in winter, the place where you live is minus 10 degrees, and you drive about 10 kilometers back and forth every day. This is considered low temperature. Short distance working conditions.

Wet wall refers to the incomplete combustion of gasoline stuck to the cylinder. This is a common problem of direct injection engines. Why does this happen? The reasons are also very complicated, so I’ll keep it short. For example, if the engine operating temperature is low, the combustion of gasoline will be insufficient, and if the injection pressure is low, the atomization effect of gasoline will not be good. For example, if the engine has a small displacement of less than 2.0 liters, The cylinder diameter of the direct injection engine is small, and the nozzle can easily spray onto the cylinder wall, causing a wet wall.

Why does the oil increase after wetting the wall?

This is easy to understand. There are pistons inside the engine cylinder, and the pistons are moving up and down. It is possible that when the pistons are moving, they will bring the incompletely burned gasoline on the cylinder wall to the crankshaft. It is also possible to bring gasoline vapor into the crankcase. The inside of the crankcase itself has an oil and gas separation device. This device will bring it back to the cylinder for next combustion, leaving the engine oil along the way. However, this device is passive. , it is relatively stupid. It first needs to volatilize the gasoline brought into the crankcase first, and then the gas expands. But if your engine is not hot yet, the gasoline brought in will not volatilize so well, so over time it will The more mixed it gets. You don’t need to worry too much. You should treat it as a direct injection engine. But the scary thing is that the oil increases. If you don’t deal with it in time, it will cause engine abnormalities and accelerate engine wear. I won’t explain it here. If there is Car owners who have been successfully recruited should go to the store to resolve the issue.

As for why direct injection engines have become the mainstream now, I can sum up the common saying, that is, they eat less (save fuel) and do more, and the displacement is still low. If you were an OEM, wouldn't you Choose such a fragrant engine?

Here we remind all car owners to develop the habit of frequent observation. Secondly, do not go for maintenance more than 2,000 kilometers before maintenance. Pay more attention to your car to avoid engine oil problems. It was quite annoying at that time. After all, if you change the engine, the money you lose when changing the car in the future will be ours.

Oil emulsification

The only reason why engine oil emulsifies is that water enters the crankcase. Everyone knows that the inside of the engine is a closed environment, so where does the water come from?

1. Antifreeze infiltration

This kind of incident usually occurs in old cars, because the cylinders of old cars basically have aging phenomena, such as a trachoma on the waterway in the cylinder and rust. The rust is through, then that's where the antifreeze gets in. For those of you who are old car enthusiasts, if there are slight cracks in the cylinder block, antifreeze may seep into the cylinder block or crankcase. ?

2. External moisture or water directly enters the engine?

First of all, let’s talk about the air filter. Generally, when washing a car, never use a water gun to spray the engine directly, because this will damage the engine. The trip computer and some electrical appliances are damaged. Secondly, if you don't handle it well, if water rushes into the air filter, even a little bit of water will be sucked into the engine, and the consequences will be disastrous. Another possibility is the turbine intercooler. When the turbine is working, it will inhale a large amount of humid air, which cannot be completely burned in the cylinder, forming a water vapor wet wall phenomenon. If the water has not been discharged after you stop the car, there will be a certain problem. There is a chance that it will flow into the crankcase, which will cause the oil inside the crankcase to emulsify.

3. Fuel leakage occurs in the cylinder

This kind of thing basically happens in old engines. Because the wear and tear is serious with age, there is a gap between the piston ring and the cylinder, then This will cause the gasoline you spray in to not be completely burned, and will enter the crankcase along the gaps. After mixing with the engine oil, an increase in engine oil will occur.

There are many other reasons, which I won’t go into here. In short, car owners are reminded that the standard for judging emulsification is to pull out the oil dipstick and check the oil quality in the crankcase to judge whether they have been infected.

Scooter for the elderly

I just want to remind all uncles, aunts and uncles that for the sake of safety, you should get off the car early. I encountered an accident before, and the uncle was driving the scooter to pick up and drop off. My child, it was a tragedy in the end. Although everyone was fine, it was too dangerous.

Public data shows that the cumulative sales of low-end electric vehicles nationwide have exceeded one million

From 2014 to 2019 alone, the number of traffic accidents involving elderly scooters reached more than 90 Thousands of incidents occurred, resulting in 18,000 deaths and 186,000 injuries.

Here we remind people who buy scooters for the elderly not to choose electric vehicles produced by irregular manufacturers just for temporary convenience

Let alone to avoid traffic regulations. Traveling on the road without a license due to restrictions, a temporary convenience may lead to the end of a lifetime.
