It's just an expensive oil change center and other consumables. If you have a car under warranty, they will not hesitate to insert some consumables not according to the regulations, thereby increasing the cost of maintenance. When a warranty event occurs, they will delay the time by referring to some kind of agreement and looking for your fault. You will achieve something only by complaint, examination and trial.
I have been serviced for 2 years. Quickly, adequately, they never insisted on unnecessary procedures and replacements. On the contrary, they said that there is a nuance, but you can ride with it for another year or 2. But there are disadvantages anyway. A lot of things where only a complete replacement is done have been done. For example, if the heating of the chair has stopped working, then the replacement is complete for 1000 rubles. In another one, the service station was repaired for 90 rubles. He has been working for more than a year. The folding mechanism of mirrors is a similar situation. Well, there is no way to edit discs on the tire. That's all I can remember in 2 years. In general, everything is fine, you can safely contact.

Recent appeals are purely negative. There was one price and availability on the phone, another on the spot, so 3 times, for calipers, springs and something else. 100,500 managers. Everyone asks you to explain what you want. He says he understood, and to translate to another, another again, hello, what happened to you. I value my time, get a bot on the phone. In fact, there are 3 people on the way to the service department. Details on prepayment, then they can call and say that they will not bring, as a result, an application for a refund and then you need to come personally, although I paid with a card, if I'm not mistaken, you can make a refund to the card here. There are currently no springs on the Mazda 6 gj. Generally) The question is, how are the warranty cards serviced?) In general, the last few weeks have been trash. There are a lot of managers and they all have different information. Apparently, relatives were attached, otherwise I cannot explain such a number.
There was another case. There was an empty first quarter of the brake pedal. And he didn't hold the handbrake well. They said the norm about the pedal, which surprised me, they called some kind of sky-high price tag a couple of thousand and a wait of 2-3 months about the brake. At the other service station there is a repair kit of calipers, they have set up and now there is a handbrake and the brake immediately grasps. It turns out that this is not the norm, it's just that this service does not want to do extra work.
There are some advantages, there are no disadvantages. I trust the service with my not the first car, everything is always on top. Excellent staff, good luck and prosperity to all!
