Galvanized body of Hyundai Creta. Why the new Hyundai Creta rusts - an investigation "Does the body rusts behind the wheel of a Hyundai creta?"

18.05.2020

Hyundai creta- Solaris among crossovers. Inexpensive if you compare it with competitors, the cost of the minimum configuration on the market is 800 thousand rubles, the "maximum speed" will cost 1.2 million rubles. The crossover is pleasant to look at, outwardly the model is practically no different from its fellow tribesmen, at least for the worse. Good quality finishing materials, comfort and ergonomics are provided. However, there are several significant "BUTs" that make the exploitation korean crossover a real nightmare and a big disappointment for the new owners of Cret.

We have collected some of the most egregious facts about the fact that the crossover from Korea is far from the most the best way for purchase.

1. The body of the Hyundai Creta is rotting!


Photo taken from www.drive2.ru

The first and most terrifying fact about the Hyundai Creta is that its body is rotting literally after a few months after leaving the assembly line! What a news!

This fact was spoken about by a considerable number of motorists who managed to take possession of the crossover and what they said was shocking, it was simply impossible to believe in it. Nevertheless, all the stories turned out to be true, a number of trusted automotive publications wrote about this, including the information published on the magazine's website "Behind the wheel".

According to data from forums, from a quarter to a third of owners are faced with this unpleasant ailment. And it would be fine if the bottom of the car would be covered with rust, at least it could be “overwhelmed”. But traces of metal decomposition appeared on the body panels and even on the roof !!! What is it like? You can read more about the study in the article "Why the new Hyundai Creta is rusting - an investigation" Behind the wheel "

And in order not to slander the Korean automaker, we note that according to official data, there are very few car owners who are faced with the problem of rust on the Hyundai Creta, 1 percent will not be typed.

Therefore, you should not panic. However, it is best to keep in mind that there is a similar problem.

In order not to tarnish its reputation, Hyundai will change the necessary technical processes by any means (or has already made edits) and new parties will get rid of the unpleasant ailment. But the sediment will remain ...

2. Crossover with a 1.6 liter engine, automatic and four-wheel drive has vague dynamics

The second annoying disappointment of the owners is that the Creta is equipped with a 1.6 liter engine, automatic transmission and four-wheel drive does not go at all. As an example, the following review https://www.zr.ru/cars/hyundai/-/creta/reviews/

Immediately, we note that this is almost the maximum configuration and it costs more than 1.1 million rubles.

According to the passport, the acceleration is 13.1 seconds, not fast, but it would seem possible to live, because we do not take a sports car. In life, everything turned out to be somewhat worse (according to the members of the forum), since acceleration from 0 to 100 km / h is not the only driving mode in real road conditions, much more often you need to quickly accelerate from 3rd, 4th gear and here everything turns out to be completely bad. A car with a 123 horsepower engine does not pull out, acceleration is sleepy and does not quite fit the realities of modern road life.

However, the disease is treated very simply, take a model with a 2.0 liter engine, overpay a little (60-100 thousand rubles), but immediately raise the safety of operation by several points up.

P.S. People differ on the dynamics of the discussions. For some, the power and traction is quite enough and they do not understand the essence of the claims of other owners. Forum club-creta.ru

3. Minimum complete set - no, no!

Hyundai differs from many in a fairly budgetary approach to pricing, but according to an old and bad tradition, if you want to buy a car as cheaply as possible, do not do it, otherwise you will go wrong. For 800 thousand rubles in the Start configuration, you will get a kind of crossover with a mono-drive on the front axle, two front airbags, steel 16 ”discs and a set of" options "that are even in Lada Kalina, such as a classic electric windows, central locking and an immobilizer.

Tell me honestly, would you buy a completely "naked" car for 800 thousand? Well this is a crossover, whatever one may say, not a car of the brand. With all due respect to the efforts of the domestic auto industry to get out of the impenetrable darkness. In this our fellows inspire optimism.

4. Creta is expensive

Yes, we say that the crossover is budget, read, inexpensive. But if we discard the minimum configurations and choose a more or less worthy one, it turns out that it is better to purchase a model from only 1 million rubles. ONE MILLION, Karl!

What is it like? It is not expensive?! Expensive, of course.

We understand that the crossover has always been an expensive pleasure and the manufacturer cannot sell its products at a loss, but ... Creta is really an expensive model from Hyundai in the budget segment.

5. Purchase queues

At the same time, to buy Creta you will have to wait. The wait will be long. In some regions, the queue is scheduled for almost six months. This is both a merit and a mistake of the manufacturer. On the one hand, the excitement is frenzied, people want to get themselves Creta, from the other point of view, it would not hurt to establish supplies or production in a larger volume. Discussion on the forum www.hyundai-creta2.ru

These were the top 5 most egregious Hyundai Creta facts. Of course, car owners will find a bunch of flaws or just gustatory flaws in the car and forums are full of discussions of this kind. We will not list negative reviews, because in our opinion, this will already be nit-picking.

What did we want to say with this material? Does not exist ideal cars... They do not exist in nature, even super-reliable Toyota breaks down. Remember after 7 years of operation. But in pursuit of imaginary savings, it is better to slow down and think, is it worth it to go on credit or give the money accumulated over the years in order to acquire a seemingly crossover, but in fact an ordinary city car named Creta? Maybe it's better to take a brand new Solaris of the second generation, a proven bestseller of the Russian market, honed over the years of release, and not to know the troubles? Or do you still think it's worth paying extra for off-road performance crossover Creta? You decide.

Many Korean fans lineup interested in the design Hyundai bodies Creta. Note that the trolley was developed by specialists from several technology centers. What happened in the end? This is exactly what we will talk about in today's article.

The body is one of the most basic parts of a car. But, oddly enough, they began to pay special attention to the structure of the frame 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 is not only an automotive concern, but also a huge conglomerate, which includes a large number of enterprises, including metallurgical ones. This is very convenient, since in the manufacture of the body of the Hyundai Creta, manufacturers have the opportunity to use steel of their own production.

The process of developing the frame of the Korean crossover took almost three years, because the first notifications of the start of work appeared back in 2011. Above, we have already said that the body of the Hyundai Creta was designed by specialists from several technology centers, which closely interacted with each other.

Initially, the body structure of the Hyundai Creta was designed using computer programs, after which the developers made several prototypes that passed a series of tests. Ultimately, one option was chosen, which later formed the basis of the Hyundai Creta trolley. It should be noted that the frame of the "Korean" has proven itself quite well in crash tests conducted by Chinese and Latin American specialists.

Body features



The frame of the Hyundai Creta is assembled by means of welding, which is automated and performed by special robots, which completely eliminates the human factor. It should be noted that before getting to the welding conveyor, the elements of the Kreta frame pass through the stamping shop, where they are pressed. In the end, a finished frame comes off the welding line, in which there are no doors and a hood.

Several types of steel are used in the body structure of Hyundai Creta:

  • Anti-corrosion 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 to frontal impact. In addition, the use of several types of steel helped to reduce the vehicle's curb weight.

It should be noted that in the area engine compartment a special transverse amplifier is installed. In addition, the side struts are additionally reinforced.

As for the roof, it is equipped with 5 supports at once, which are able to prevent strong creasing in the event of a car rollover.

However, all the listed features of the Hyundai Creta trolley are only a small part of what the Korean developers have pleased us with.

There was no doubt that the body of the Hyundai Creta will be galvanized. However, the news of the purchase of Russian metal alarmed some. However, in vain.

After the announcement of the imminent start of sales of the new Korean SUV, many motorists became interested in the question - is the Hyundai Creta body galvanized? Of course, few have allowed themselves to think that automobile concern with a world name will start selling cars that in a year or two will be covered with rust. Nevertheless, after the news that Russian metal would be used for production, potential buyers had a question about its quality. Will it compare to Korean steel? And what kind of anti-corrosion treatment will the Creta body be subjected to?

Korean technology

During the production of the SUV, several types of metal are used:

- galvanized steel like Hyundai Hysco;

- stainless steel products of the BNG Steel and POSCO types.

Steel from Posco is also used for the production of SUV components.

Such steel perfectly resists corrosion and withstands corrosive environments. In addition, SUV bodies are additionally processed at the factories. This is done by cataphoretic priming, for which a primer is used, developed with the use of epoxy-type components, characterized by a reduced drying temperature, as well as copolymers (vinyl and acrylic), which contain amine-group resins.

For the body of the crossover, galvanized steel is used.

The strength of Hyundai's cataphoresis priming is that, provided a thin protective layer is provided, an excellent degree of metal protection is achieved. In combination with galvanizing, the car body successfully resists not only corrosion, but also alkalis, salts and other reagents. The use of such methods allows the concern to guarantee the quality of its products.

Use of Russian metal

If confidence in Korean technologies in Russia is growing from year to year, many were wary of the news that the metal for the Hyundai Creta model will be supplied by the domestic concern Severstal. It was with this conglomerate that Hyundai Motor Manufacturing Rus signed a contract until the end of 2016, which implies the shipment of cold-rolled and galvanized metal products. The Cherepovets Metallurgical Plant will supply steel for the assembly plant. Messages from the metallurgical giant and Hyundai have repeatedly said that the products purchased from Severstal fully comply with all the standards of the Korean manufacturer.

Severstal has been selected as the Russian metal supplier.

In this case, both parties can consider the signed contract successful. After all, Severstal has received a new, solvent client, which is especially important in light of the anti-dumping investigations initiated by the EU against Russia and China. As a result of the case, duties were imposed on Russian cold-rolled steel. Hyundai also gets an excellent opportunity to reduce the cost of the SUV and increase the degree of localization.

Hyundai Manufacturing Rus.

At the moment, localization is about 50%. However, the main factor is local workers. At first glance, the plant is supplied with a wide range of products. Russian production... However, for the most part, these are either repackaged or assembled in the Russian Federation foreign components.

Russian steel

The metal supplied by Severstal is galvanized cold-rolled sheets. This coating guarantees effective corrosion protection. The amount of zinc used depends on the preferences of the customer and can reach up to 450 g / m². There is no data on the thickness of galvanizing, however, it is known that the thickness of Hyundai Creta body panels ranges from 0.6 to 0.8 mm. Therefore, there is clearly no need to fear the appearance of rust on the body of the crossover.








Anodic coating of the body of Hyundai Creta

The galvanizing of the body components of the Hyundai Creta, like other cars, occurs by applying protective coating anode method. It consists in the fact that automotive steel is coated with a layer of metal with a lower electrochemical potential - zinc.

An example of a galvanized metal.

The peculiarity of this method is that it not only provides mechanical insulation of steel, but also guarantees electrochemical protection. This means that even small damage to the zinc layer, which is inevitable during the operation of Creta (chips and scratches from pebbles, branches, etc.), will not lead to corrosion. Unlike a cathode coating, which can provide protection only if the layer is intact.

Crete's body galvanizing technology

The body of this crossover is galvanized by a galvanic method. Of course, it is inferior in efficiency to thermal galvanizing, which is used for bodies of premium models, but significantly better than cold galvanizing. In general, this method is optimal for a SUV in terms of price / efficiency ratio.

Galvanic galvanizing of Hyundai Kreta occurs according to the following scheme:

  1. The Creta body is immersed in a special container filled with zinc solution.
  2. Next, the terminal (minus) is connected from the electric current source to the body.
  3. The capacity is supplied from the positive terminal.

The body is immersed in a bath with zinc solution.

Due to the electric current in the container, electrolysis occurs, which creates a zinc layer on the surface of the body. This layer reliably protects the car body, and its lower price (compared to the thermal method) allows you to keep an adequate price.

We decided to conduct our own investigation, which you can familiarize yourself with in today's article - why Hyundai Creta rusts. Every more or less experienced car owner knows that steel, due to the peculiarities of its chemical composition, begins to rust. Considering the current pace of car production and the speed with which motorists change cars, no one is surprised by the abundant foci of corrosion that occur even during the warranty period. But when this happens in the first few months of operation, it is at least puzzling. In the following paragraphs, we will try to find the root of the problem - Creta rusts, using the example of the trunk of the most popular crossover on the Russian market.

At the beginning of 2017, complaints from the owners of the Korean crossover, whose Hyundai Kreta rusts, began to appear systematically. Interestingly, the main centers of corrosion appeared on the trunk lid, namely on its outer part. When Creta rusts, paint swells in problem areas - this is the first wake-up call. It is worth noting that among the "defective" Greta there were many new cars in operation for 2-3 months. It was also not possible to establish any regularity with the colors of the problematic bodies. At first, the white and silver colors aroused suspicion, but later the whole palette was negatively distinguished.

Owner reviews

Based on the reviews of the real owners of the SUV, the most vulnerability, in terms of the appearance of corrosion, is the rib under the glass of the trunk of the car. Rust marks are clearly visible on light body colors.



The employees of the official dealerships of the Korean company calmly accepted the complaints of dissatisfied customers, offering to paint over for free problem place... But there were cases when the company's specialists accused the owners of the car that Creta was rusting, arguing that it was unregulated mechanical interference. In February 2017, employees of the Hyundai technical center informed engineers that the Hyundai Creta was rusting. The plant gave the command to paint over or replace problematic elements, and then send them for examination.



The ordinary owners of Greta did not realize the real scale of the problem, because the manufacturer did not report exact numbers until recently. Motorists are of the opinion that the percentage of Hyundai Creta rusting is scanty compared to the total number of cars sold. Enterprising car forum administrators have started to create threads addressing this problem. This caused a lot of controversy and discussion. The poll results shocked - Creta rusts in 25% of owners. It is not strange that a petition was sent to the manufacturer's address, which, unfortunately, did not collect very many signatures.

Other places where corrosion appears are the spoiler and the surface near the secondary brake light. Rust often occurs in the vicinity of the lantern. Less often - at the place of contact between metal and plastic.

Fortunately, the Korean company offers a long-term 5-year paintwork warranty. And in general, manufacturers are very loyal to customers in this regard. But it's not even a matter of loyalty and the prompt assistance of specialists - motorists are interested in the reason for the appearance of rust. It’s scary to imagine what could happen to the body in a year or two if the trunk lid gave up after a few months. The situation was further exacerbated when car owners began to post photos of the Creta rusting on the forums. The centers of corrosion on the inside of the body looked especially scary. Optimism was not added to the pictures with swollen paintwork - mainly in the area of ​​the taillights and the panel cover. The real panic was caused by reports of some motorists that rust reappears even after repainting.



Again, the most common place where Hyundai Kreta rusts is the ribs under the lanterns.

In May 2017, it became clear that Korean manufacturers were not sitting idly by - they conducted an internal investigation and issued a bulletin Maintenance car. According to the document, all Hyundai Greta cars produced from July to December 2016 are subject to free inspection at branded services. If even minimal traces of corrosion are found, the auto repairman must replace the element. If cleaning the rust on the body panels has any effect, a repainting option is also possible - it all depends on each individual case. No matter how hard we tried, we could not find information in the bulletin regarding the causes of rust - it remains a mystery.

All that remains is to collect bit by bit the available information and compare it with your own guesses.

The optimism is enhanced by the fact that the newsletter applies to cars manufactured before December 2016. This may mean that the developers were able to find the root of the problem. Judging by the owners' feedback, crossovers assembled in 2017 don't rust like that. The developers did not want to open the curtain of secrecy - this is a little unfair to customers.

Introducing you real review of one of the owners of the crossover: “Hyundai Creta rusts as follows: on the surface of the trunk lid there are several blisters of paintwork. The car was assembled in August 2016, and to be honest, I was surprised by these pimples. Fortunately, a thorough examination of the body surface revealed no other rust spots. Interestingly, Crete's wife, released at about the same time, but only of blue color- I could not find anything like it on it. Well, how can you guess here? "



The real extent of the problem is still unclear. According to the survey results, only a quarter of car owners faced the problem of corrosion. But no more than 1,000 people took part in these questions, which certainly does not add objectivity.

The collective petition sent to the manufacturer collected only 427 signatures. To understand the comic situation, just look at the figure of sold crossovers in 2016 - 22,000. Dealers took advantage of these statistics and argue that the percentage of "infected" cars is negligible. That is, in theory, the chance to acquire a rust-prone 2016 Cretu is no more than 25%.

Slightly clarified the situation of measuring the thickness of the paintwork: it turned out that in problem areas this indicator is less. After this information "bomb", all experts agreed that the main problem lies in the unevenness of the paint layer. Almost immediately, videos appeared on the Internet, in which the device for measuring the thickness of the paintwork shows only 80 microns - this is very little. Of course, everything can be attributed to the wrong setting of the device, but the presence of a problem confirms many other facts. This is most likely the main reason that Creta rusts.



We decided to conduct an experiment by independently measuring the thickness of the paintwork of the problematic cars of the Korean company. Of course, we did not manage to detect extreme indicators of 80 microns, but the unevenness of the layer did take place. For the purity of the experiment, we chose cars of different colors from 2016 and 2017. Oddly enough, but all "participants" showed approximately the same results.

The average thickness of the Kreta paint coating is 110 microns. A bit subtle, but this value cannot be called critical. In general, the thickness of the paintwork on the surface of various body elements ranges from 120-150 microns.

This is the norm for a factory-painted vehicle. But there are examples showing great contrast in terms of thickness.

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

Almost every automotive concern faced similar problems. In most cases, the most problematic area was the trunk lid, namely the niches under the plastic linings. Literally after a year or two of operation, rust began to spread to the entire body. This is true for the first Ford Focus and Mazda CX9. Toyota stood out noticeably, offering new cars with rusting hoods. In the situation with Ford and Mazda, the problem area was simply repainted. A Toyota dealer, known for his loyalty to consumers, has created a large-scale service campaign offering free replacement of problematic elements.



Output

If we carefully analyze all such cases, we can conclude that Creta rusts in one specific place - other body elements are not subject to such a "sore". The biggest disappointment was hiding the causes of the problem and diligently hiding the facts - this is unfair to customers. Everyone is wrong. Both Ford and Mercedes have had similar blunders. But unlike Hyundai, these dealers immediately admitted their mistakes.
