Car supplies exaggerated maintenance pitfalls

Say it is easy to buy a car, it is difficult to use a car. In the automotive market environment driven by economic interests, it is not easy to buy a car with the best price at the most suitable price, but when it comes to buying automotive supplies, it suffers from all sorts of fraudulent and even useless maintenance products; During the inspection, it was also necessary to be pitted by all kinds of tricks for car repair expenses... As a car racer, it really is not a hassle. In this issue, this reporter has summarized and summarized the pitfalls of car maintenance products and vehicle maintenance when interviewed through investigations, helping owners to polish their eyes and safeguard their rights and interests. The car is a “little wife” for many male owners, and a “protective god” for female owners. Many car owners have been on the “Little Wife” and “Protective God” for at least half of their hearts since they bought the car. How to maintain, how to decorate, and how to modify are all things that many owners are wondering about. However, many automotive supplies are dazzling, cooling spray, nano-oil-reducing agent, photocatalyst deodorant, inorganic oil running anti-wear agent ... ... these products, the name of the light to listen to the owner of the heart.

But behind these names is often the "trap" that tempts consumers to pay, because most of the functions they claim are to fool you. Let reporters accompany you to expose the common lies in the automotive supplies market.

Lie 1: The fuel-saving products make the car become "perpetual motion"

In the auto parts market, there are countless "high-tech" energy-saving products. Almost every economizer claims that its working principle is scientific and reliable. For example, “Using infrared technology to change gasoline molecular bonds and activate oxygen molecules can achieve the effect of assisting in burning and fuel economy”; “Adding nanomaterials to the rubber tube, the aggregated oil molecules are broken into individual oil molecules. Can promote the fuel to enter the cylinder and fully mixed with air to achieve complete combustion." It sounds like a good thing. Under the temptation of advertising, a car owner spent more than 500 yuan to install an infrared fuel saving pump. One month later, Mr. Li found that the car was not fuel-efficient but that the power was becoming weaker.

007 Secret: The existence of various kinds of fuel-saving products on the market is actually a concept of "permanent motivation" and is purely a flicker. For example, if you claim to use infrared energy to achieve a fuel-saving effect, in fact, infrared energy will cause gasoline to evaporate more easily. What's the reason? Besides nanotechnology, nanotechnology is not energy. How can it help combustion? There are also many fuel-efficient products that control the engine's fuel intake, causing many vehicles to suffer from engine failure. If these fuel-saving products can really save fuel, then why do all the big car companies that squeezed into the list of energy-saving subsidies need to make technical reforms? It can be seen that this is not the case.

Lie II: Anti-wear products make cars free from oil

Recently, a new type of product has been found in the automotive supplies market. It is said that the vehicle can withstand the use of inorganic oil after use. For the owner, it is not necessary to spend a few hundred dollars to change the oil frequently. The product specification also stated that the anti-wear products are not only free of repair and repair, but also can repair the wear of vehicle components, even can "fuel savings" to save 30% of fuel, so that the exhaust gas in the exhaust gas is reduced by 2-10 times, known as absolute Environmental protection. If the owner chooses to install it, he will be warned by the 4S shop that “If such products are installed, quality problems will occur during the warranty period, and 4S stores and manufacturers are not responsible for the warranty”.

007 Secret: According to experts, most of the "anti-wear products" work principle is to rely on deposition and adsorption to fill the piston and the cylinder wall wear gap, but in order to pass this small product to try to make the engine's crankshaft, bearings, Metal parts such as gears and valves will not be thickened, which seems to be a bit exaggerated; adding additives such as anti-wear agents may cause delamination of the engine oil and other disorders, and the owner should carefully select.

Lies 3: Photocatalyst cures car odors

In order to get rid of the heavy interior taste in the car, owners have listened to the 4S shop's recommendation to use "photocatalyst" products. Not to mention that each time the cost of 800 yuan is expensive, most car owners said that after the effect was not as obvious as advertising.

007 Secret: Some photocatalyst products on the market cost only tens of dollars, but when it becomes a "maintenance package", the profits from the charges are no less than explosion-proof membrane products. In addition to flavor products, the role is certainly limited, and the effect is even more unlikely to be immediate. Photocatalyst products are divided into two kinds, water-soluble and oil-soluble, and water-soluble photocatalysts are relatively environmentally friendly and safe. However, the problem of technology is a problem faced by many photocatalyst manufacturers. General manufacturers use oil-based photocatalysts, but due to unknown organic solution components, there is no guarantee. Does not produce toxic effects. The bactericidal effect of photocatalyst products is quite good, but there is no product on the market that can completely cure car odors once or twice. Car owners put carbon in addition to formaldehyde to accelerate deodorization, but they are more reliable.

Lie 4: Car Sealing Permanent Protection Car Paint
When buying a new car, the owner will generally consider making a full car seal. This will make the car look like "a layer of protective film", so that the paint has been bright as new, and some even claim to have done a year after sealing without waxing.

007 Secret: Car sealing is like icing on the cake, but the price of sealing glaze is not cheap. At present, some glazed products on the market are classified as jerry-type and have many fakes and inferiors; while the so-called imported products are mostly products of small factories in the Mainland, the car has been careful to spend money and has no effect. In particular, some types of glazes with short construction time (less than one hour) and less construction procedures can be said to be white. The enamel effect of enamel can not be overstated. It is definitely a big component of 忽悠. Generally two months later, the car glaze will start to oxidize and will be fully oxidized after six months. After oxidation, not only can it not protect car paint for a long time, but it may also corrode car paint. Sealing glaze is just a self-made word for the domestic auto beauty industry. It is deeply waxed abroad. Waxing only needs a few tens of dollars for a wax, and a few to a few hundred for a sealing glaze, and as much as a thousand dollars. To put it plainly, sealing the glaze is just a concept introduced.

Car maintenance traps more owners need to wake up
Car repair experience always makes the owner "shocking" because there are too many "traps" in it. To replace the original accessories factory accessories, which can reach several times the difference; even some repair shop will soon after the warranty repair vehicle, deliberately delayed repair, after the warranty period, the owner if you want to update the accessories can only pay for their own pockets ... The maintenance of these "pit fathers" left the owner miserable. After investigating the report, the newspaper summarized four types of maintenance traps, which can be used as tips for car owners.

"Hengjiao" maintenance 1: shoddy several times the difference

Owners pay for new products, while maintenance companies respond with defective products or even refurbished products. In fact, in the auto repair market, whether it is a 4S shop, a garage or auto parts city, or a roadside shop, this situation is not uncommon.

The owner of Mr. Xie’s LaCrosse vehicle has been purchased for nearly two years and has been well maintained. Not long ago, due to a reverse mistake, the side of the car was rubbed and the paint was scratched. Subsequently, he drove the car to a car repair shop to make up the paint. Mr. Xie did not understand lacquer, so he listened to the maintenance staff's suggestion to choose an imported paint with a price of 300 yuan per liter. After picking the paint, the maintenance staff told him that the paint was taking longer and he couldn't take the car on the first day. So, Mr. Xie went home and prepared to pick up the car the next day.

The next day, he drove home his already lacquered car. After a few days, I occasionally chatted with a friend who knows how to paint. When the friend knew it, he would go and see his car. After seeing the car, after some inspections, a friend told Mr. Xie that the paint used to make up the paint was actually an ordinary paint, and the unit price was 100 yuan, not the import paint that it said was more expensive. After learning of this incident, Mr. Xie immediately negotiated with the maintenance party and found a third-party expert to help identify; eventually the auto repair shop admitted that the paint had been changed and agreed to pay compensation.

Repair of "Hangsong" 2: Deferred repair delay to avoid warranty
At the end of last year, Mr. Qi’s vehicle mileage had reached 45,000 kilometers. As usual, he should go for maintenance. So he sent the car to the 4S shop.

The next morning, Mr. Qi went to the 4S shop to pick up the car, but found that his car was on fire, the throttle did not respond, and normal driving was possible after 20 minutes.

Moreover, the same problem persisted for many days. Therefore, Mr. Qi decided to leave the car in the 4S shop for repairs. The 4S shop said after the test that there is a problem with the fuel tank and it needs to be replaced. However, after waiting for one month, the 4S shop informed Qi that Japanese manufacturers agreed to replace the fuel tank for free. Subsequently, Qi's car parked in this 4S store for nearly a month before news. But this time, the 4S shop did not replace the fuel tank for its car, but informed him that it was necessary to replace the fuel tank after May.

This news made him unusually angry. He found it incredible that the 4S shop informed the need to change the fuel tank after two months of checking the breakdown of its own car, and the entire maintenance time even delayed to more than six months.

As we all know, the general automobile maintenance costs are calculated in man-hours (in addition to parts replacement costs). A few maintenance workers deliberately delay repair time to increase income. In addition, even some repair shops will soon be overhauled maintenance vehicles, deliberately delay repairs, after the warranty period, the owner if you want to update the accessories can only pay for their own pockets.

"Hangsong" maintenance 3: cutting corners, sloppy things
The owner, Mr. Li, had been driving an accident in the field. Afterwards, he towed the car to the local 4S shop for maintenance. The total cost was 56,000 yuan. Twenty days later, he took a car to return home, but the abnormal noise of the car was very serious, including the body and the chassis.

On the day of arrival, Mr. Li sent the car to the 4S shop near his home and found that there were many serious maintenance quality problems in the car. "Front-wheel brake brackets and fixed-direction linkage rod nuts are detached from more than half, and are accompanied by abnormal sounds. There are also multiple oil leakages in the brake oil pipes, and the welding of fuel tanks, tail boxes and other parts is rough; more exasperating is the front of the car. Some parts of the department were actually tied with cloth and wire..." he introduced. Mr. Li had already been involved with the accident repair station for many times and failed. The other party even said that “any customer after the car has been brought to the car has nothing to do with them”.

"Kang" maintenance 4: sky-high asking prices, over-maintenance

Last September, Ms. Tan used a five-year car and suddenly felt a lack of motivation. So she drove the car to the 4S shop for inspection. After listening to Ms. Tan’s description of “symptoms” and doing a simple check, the maintenance staff told Ms. Tan that the engine of her car was serious. If it was to be repaired, the cost would be more than 10,000 yuan.

This is somewhat sensational. She is about to drive to another repair station. When the shop owner inspected the car, he found that the fault was not in the engine but in the clutch. After spending more than 1,000 yuan for the clutch, the car returned to normal.
