We decided to conduct our own investigation with which you can get acquainted in today's article - why Hyundai Creta rust. Each more or less experienced car owner knows that steel, due to the peculiarities of its chemical composition, begins to rust. Given the current pace of automotive production and how vehicle speeds are replaced by cars, no one surprises abundant corrosion foci, arising from the period of warranty. But when this happens in the first few months of operation, it is at least causes bewilderment. In the following items, we will try to detect the root of the problem - Creta Rust, on the example of the trunk of the most popular crossover in the Russian market.

In early 2017, the complaints of the owners of the Korean crossover, who rust Hyundai Kret began to appear. Interestingly, the main foci of corrosion appeared on the lid of the trunk, namely on the external part of it. When Creta rusts, paintwork is swollen in problem areas - this is the first alarming bell. It is worth noting that among the "defective" Greta, there were many new cars in operation 2-3 months. Establish some regularity with the colors of problem bodys also failed. At first, the suspicions were called white and silver color, but later the whole palette was negatively distinguished.

Ownership reviews

Based on the reviews of the real park operators, the most vulnerable place in terms of corrosion appearance is the rib under the glass of the car trunk. Traces of rust are well visible on bright colors of the body.

Employees of the official dealer centers of the Korean company quietly perceived the appeals of unhappy customers, offering free to paint the problem space. But there were cases when the company's specialists accused that Creta rust, the owners of the car, arguing it with non-inflammatitious mechanical intervention. In February 2017, Hyundai Techno Center employees told engineers that Hyundai Creta rust. The plant gave the command to paint or replace the problem elements, and then send them to the examination.

The usual owners of Greta did not realize the real scale of the problem, because the manufacturer did not report exactly to the latter. The car enthusiasts have the opinion that the percentage of rust Hyundai is meager, compared with the total number of cars sold. Advanced automotive forum administrators began to create topics concerning this problem. It caused a lot of disputes and discussions. The results of the surveys were shocked - Creta rust in 25% of the owners. It is not strange that the petition was sent to the manufacturer's address, which, unfortunately, not so many signatures.

Among other places of corrosion, we will note the spoiler and the surface near the additional stop signal. Often, rust occurs near the lantern. Less often - at the place of contact of metal and plastic.

Fortunately, the Korean company offers a long-term warranty on the paintwork - 5 years. And in general, manufacturers are very loyal to customers in this regard. But the point is not even in loyalty and in the operational assistance of specialists - motorists are interested in the reason for the appearance of rust. It is terrible to imagine what can happen to the body for the year or two if the lid of the trunk surrendered after a few months later. The situation was further aggravated when the car owners began to throw photographs of how Creta rust. Especially terribly looked corrosion foci on the inner part of the body. Optimism did not add pictures with a scattered paint coating - mainly in the zone of the rear lights and the panel covers. This panic caused messages of some motorists that rust reuses even after repainting.

Once again we repeat: the most common place where Hyundai Cret is rust, it's a rib under lanterns.

In May 2017, it became clear that Korean manufacturers do not sit back - they conducted an internal investigation and released a car maintenance bulletket. According to the document, all Hyundai Greta cars, released from July to December 2016, are subject to free inspection on branded services. If minimal corrosion traces are detected, the car must carry out the element replacement. If the rust stripping on the body panels brings some effect, an option with repainting is also possible - it all depends on each individual case. No matter how hard we tried, failed to find information about the reasons for the appearance of rust - it remains a mystery.

Everything that remains is to collect on tagging information and compare it with your own guesses.

Optimism adds the fact that the Bulletin's action applies to cars issued until December 2016. This may mean that the developers managed to detect the root of the problem. Judging by the reviews of the owners, crossovers collected in 2017, so do not rust. The developers did not want to open the curtain of secrets - it is a little unfair to customers.

We present you with a real response from one of the owners of the crossover: "Rust Hyundai Cretage as follows: a few swollen coating appeared on the surface of the trunk lid. The car is assembled in August 2016, and me, honestly, surprised these pimples. Fortunately, a thorough examination of the body surface did not reveal other foci of rust. Interestingly, the wife of Kret, released at about the same time, but only blue - I could not find anything like it on it. Well, how are you guess here? "

The real scale of the problem is still unclear. If you believe the results of polls, then only a quarter of the car owners faced the problem of corrosion. But no more than 1,000 people took part in these issues, which accurately does not add objectivity.

The collective petition sent to the manufacturer collected only 427 signatures. To understand the comicness of the situation, it suffices to look at the indicator of the soldiers sold in 2016 - 22,000. Dealers took advantage of these statistical data and argue that the percentage of "infected" cars is meager. That is, in theory, the chance to acquire the release prone to Rust 2016 is no more than 25%.

A slightly clarified the situation of measuring the thickness of the paintwork: it turned out that there is less on problem zones. After this information "bomb", all experts agreed that the main problem lies in the uneven layer of the paintwork. Almost immediately, videos appeared on the Internet, on which the LCP thickness measurement device shows only 80 microns - it is very small. Of course, everything can be written off to the wrong adjustment of the device, but the availability of the problem confirms many other facts. Most likely, it is precisely the main reason that Creta rust.

We decided to conduct an experiment, independently measuring the thickness of the paintwork of problem vehicles of the Korean company. Of course, we failed to detect extreme figures in 80 microns, but the layer's unevenness took place. For the purity of the experiment, we chose cars of different colors 2016 and 2017 release. Oddly enough, all the "participants" showed approximately the same results.

The average of the thickness of the paint and varnish coating is 110 microns. It is thin, but this value can not be called critical. In general, the thickness of the LCP on the surface of different body elements varies in the range of 120-150 microns.

This is the norm for the car with the factory painting. But there are examples demonstrating a large contrast in thickness indicators.

On one of the cars, the thickness of the paint under the mirrors is 160 microns, and above the door handle - 120 microns. It is not known how it happened, because the process of painting is fully automated. The developers also left without comment.

With such problems, almost every car concern faced. In most cases, the most problematic zone was the lid of the trunk, namely the niches under plastic lining. Literally in a year or two of operation, the rust began to spread to the whole body. This is relevant for the first Ford Focus and Mazda CX9. The company Toyota was noticeable, offering new cars with rusting hoods. In a situation with Ford and Mazda, the problem plot was simply repainted. Toyota dealer, known to consumers, created a large-scale service campaign offering free replacement of problem elements.

Output

If you carefully analyze all such cases, we can conclude that Creta rust in one definite place - other body elements are not subject to such a "sore". The highest disappointment was the hide cause of the problem and diligent silent of facts - it is unfair to customers. Everything is mistaken. Such misses happened to Ford and Mercedes. But in contrast to Hyundai, these dealers immediately recognized their mistakes.

Body galvanich Hyundai Creta

The table indicates - galvanized Lie car body Hyundai Creta, produced from 2015 to 2019,
and handling quality.

	Treatment	A type	Method	Body condition
2015	Partial	Cold Ocinkovka		Total galvanis: bad The car is already 4 years old. Recalling the age and quality of processing with zinc of this machine (under normal operating conditions), the first corrosion will begin in 2 years.
2016	Partial	Cold Ocinkovka	Application of zinc-containing coating	Total galvanis: bad Machine for 3 years. Having taking the age and quality of processing with zinc of this machine (under normal operating conditions), the first corrosion will begin after 3 years.
2017	Partial	Cold Ocinkovka	Application of zinc-containing coating	Total galvanis: bad The car is already 2 years old. By taking the age and quality of processing with zinc of this machine (under normal operating conditions), the first corrosion will begin after 4 years.
2018	Partial	Cold Ocinkovka	Application of zinc-containing coating	Total galvanis: bad The car is already 1 year. Recalling the age and quality of processing with zinc of this car (under normal operating conditions), the first corrosion will begin in 5 years.
2019	Partial	Cold Ocinkovka	Application of zinc-containing coating	Total galvanis: bad The machine was released this year. Recalling the age and quality of processing with zinc of this machine (under normal operating conditions), the first corrosion will begin after 6 years.

In case of damage to the galvanized body, corrosion destroys zinc and not steel.
Types of treatment
Over the years, the process of processing itself has changed. Machine Motor - it will always be galvanized better! Types of galcriptions
The presence of zinc particles in the soil covering the body - does not affect its protection and is used by the manufacturer for the word "galvanized" in promotional materials. . Test The results of tests of cars from conveyor with the same damage (cross) on the bottom of the front right door. Tests were carried out in the laboratory. Conditions in the chamber with a hot salt fog, for 40 days correspond - 5 years of normal operation. Car with hot galvania (layer thickness 12-15 μm)
Car with galvanic galvania (layer thickness 5-10 μm)

Car with cold galvanized (layer thickness 10 microns)
Car with zincometal
Car without galvanovka
It's important to know - Over the years, manufacturers have improved the technology of galvanizing their cars. Machine is a little - will always be galvanized better! - Coating thickness from 2 to 10 microns (micrometers) provides excellent protection against the occurrence and distribution of corrosion lesions. - the rate of destruction of the active zinc layer, in the place of damage to the body, is from 1 to 6 μm per year. Zinc more actively collapse at elevated temperatures. - If the manufacturer has a term "galvanized" not added "complete" It means that only implanted elements have been processed. - Pay more attention to the presence of a manufacturer's warranty on the body, rather than loud phrases about galvanizing from advertising. Additionally

Noticing corrosion foci on the trunk lid appeared in early 2017. Basically, distinct traces of the paintwork of the paint coating were concerned on the external panel of the body element. And often the trouble overtook the fresh cars, which were operated only three to four months. In the initial period, it seemed that the problem was touched only by owners of cars of certain colors (white and silver), but quite quickly "noted" and the rest of the palette.

Employees most of the dealer centers behaved correctly and after inspecting cars decided to repaint a suspicious detail. Although there have been enough cases when negligent engineers under warranty managed to find mythical traces of external mechanical impact (microscopic) and unfolded owners. According to representatives of one of the dealership services, in February 2017, the technical centers began to send information on this issue to the manufacturer. The plant instructed to repaint or change the lids depending on the case, as well as send it details for the examination.

Alas, ordinary owners were in the information vacuum, and the manufacturer did not indulge the comments, limited to the words that the percentage of problem machines is meager compared to the volume of all cars sold at this point. As a result, passions and disputes were broken on the forums in an attempt to independently understand the question and understand the real scale of trouble. According to the results of questionnaires on sites, about 25% of the owners collided. A collective electronic petition to the manufacturer has become a logical continuation of the story. True, she gathered not so many signatures, as expected.

Hyundai, including paintwork (5 years or 150,000 km) and, mostly, the friendly policy of dealers in this matter. However, the owners were very disturbed by the issue of the nature of the trouble with rust. If the trunk lid snaps up so quickly, what can happen in a year or two with the rest of the body?! In addition, photos and photographs of corrosion foci on the inner edges of the body element began to appear on the forums. The peeling of the paint coating appeared in the rolling zones of the cover panels and on the ribs of the niche under the lanterns. Optimism and reviews of some owners, talking about the reappearance of rust after repainting the lid and even after it is replaced.

The outcome of the internal study of the issue was the exit in May of this year of the technical bulletin prepared by the manufacturer. The document prescribes a mandatory inspection of cars issued in the period from July 26 to December 15, 2016, which come to the service for any work. In case of detection of corrosion foci in the places described above, the dealer must repair (repainting) or replacing the lid. The question is solved in each case after stripping rust. If its traces cannot be completely removed, then it is necessary to replace the body element. Unfortunately, there are no information about the causes of defect and changes in production in the Bulletin.

On coffee grounds

Alas, the manufacturer did not give any comments for the editorial request "driving" about the details of the problem with rust. Therefore, it remains only to build assumptions, comparing the information received from some dealers and on the owners' forums, as well as the experience of operating a creek in our park.

Judging by the fact that the service of the service bulletin applies to the machines produced before December 15, 2016, there is hope that the causes of the defect are found and changed to the technological chain on the conveyor. At least there is no information about such issues on cars 2017 release. The manufacturer did not want to open the secret, and in service with the employees of the dealer centers only assumptions about the causes of such a strange problem.

Real scales are also unclear. The questionnaires on two major forums have shown that about 25% of the owners collided with rust. However, only 850 people took part in these votes. Not so many collected collective electronic petition - today only 427 signatures. For understanding, in 2016 almost 22,000 kings were sold. About the low percentage of "patients" machines identified during the service bulletin, they say some dealers. That is, on paper owners of cars released before December 15, 2016, not so much chance to see rust on the lid of the trunk, but no one is insured from this.

In the process of disputes about the nature of rust, a curious fact popped up - uneven and in some places too small layer thickness. On the Internet there are rollers, where, on the edges of body panels, the instruments show only 80 microns, as if there is no lacquer. At the same time, video participants confirm on targeted probes that the thickness gauge is calibrated correctly.

The thickness of the paint and varnish coating was tested for several machines. Examples with indecently low 80 microns could not be seen, but thin and too inhomogeneous places were found. Two Krett from our Park (2016 release) and several new cars (2017) were participating in the experiment (2016), which were still waiting for buyers. In general, all participants with different body colors showed close results.

A really coating layer on the edges of body panels is thin (100-110 microns), but these are not criminal values. For the most part, the thickness difference throughout the car ranges from 120 to 150 microns, which is normal for the new car in the factory paint. However, there are examples of a very significant difference in one body element. The brightest of them is the edges of the front doors. Under the mirrors, the calibrated device shows about 160 microns, and above the handle - 120 microns. Strange figures, given what is robotized at all modern factories. Alas, but these facts remained without comment from the manufacturer.

"Rusty" problems in their time distinguished themselves many autohygigants. In some of these were famous weaknesses on the trunk lid - niches under plastic lining. After a couple of years of operation, rust appeared in these places. This is the second generation and first Mazda CX-9. More brightly distinguished Toyota with rusting hoods on fresh cars. In the first case, with a complaint of the owner in the warranty period and the absence of traces of external influence, the detail was repainted, and in the second, the manufacturer organized a whole service campaign to correct the defect on the soldiers sold by its policies.

Given the many years of experience of such, it is unlikely that problems with the lid of the trunk on the attrates speak about the misses all over the body. However, Koreans could show more attention to the concerns of the owners and raise the veil of secrecy. Sooner or later, all autohygids are mistaken, especially for the first anniversary machines. No one has suspicions and questions when the manufacturer recognizes some misses and declares the adjustments to the production cycle, not forgetting the warranty obligations to the owners of potentially "patients" machines. But the informational vacuum only cultivates concerns and generates negative.

Why rust new Hyundai Creta - investigation "driving" Why rust new Hyundai Creta - investigation "driving"

Many fans of the Korean model range are interested in the design of the Hyundai Creta body. It should be noted that specialists of several technocenters were engaged in the development of a cart. What ultimately did it happen? Just about this we will talk in today's article.

The body is one of the most basic parts of the car. But, oddly enough, special attention of the framework of the frame began to be given relatively recently. If earlier, the cart was no more than just a piece of metal, now it is an aerodynamic element made of high-quality materials.

Development process

As you know, Hyundai's company is not only a automotive concern, but also a huge conglomerate, which includes a large number of enterprises, including metallurgical. It is very convenient, as in the manufacture of the body of Hyundai Cret, manufacturers have the ability to use steel products.

The process of developing the Korean crossover carcass took almost three years, because the first notifications about the start of work appeared in 2011. Above, we have already talked about the fact that the body of Hyundai Protete was designed by specialists of several technocenters, which were closely interacted among themselves.

Initially, the Hyundai Creta body design was designed using computer programs, after which the developers made several test samples that have passed a series of tests. Ultimately, one option was chosen, which later and Loe is based on the trolley of Hyundai Cret. It is worth noting that the Korean frame has proven to be good for krash tests conducted by Chinese and Latin American specialists.

Features of the body

The frame of Hyundai Cretage is assembled by welding, which is automated and carried out by special robots, which completely eliminates the human factor. It is worth noting that before getting to the welding conveyor, the framework of the carcass are a stamping workshop, where their press is carried out. Ultimately, the welding line comes with a finished frame, in which there are no doors and hood.

In the body design Hyundai Creta, several types of steel are used immediately:

• Anticorrosive steel.
• High strength steel.
• High-tech metal used in the front of the car.

The use of these materials allowed manufacturers to increase the crossover resistance rate during frontal impact. In addition, the use of several types of steel helped to reduce the car's equipment.

It is worth noting that in the area of \u200b\u200bthe engine compartment there is a special transverse amplifier. In addition, the lateral racks are additionally reinforced.

As for the roof, it is equipped at once with 5 supports, which are able to prevent strong faming in case of tipping the car.

However, all the listed features of the trolley of Hyundai Cretage are just a small part of what the Korean developers have pleased.
