The myth of Japanese reliability: Mazda and its 600,000 km

Mazda: The Car That Doesn't Break Down and Bores Its Owner

There's a problem with Mazdas that no marketing campaign could sell: they're boring. Someone who bought a second-hand white leather Mazda 6 petrol model with 300,000 kilometers on it has now clocked up 550,000, and the car still starts like the day it was new. The only thing replaced has been the clutch. The owner is eager for it to break down to justify a new purchase, but there's no sign of it. This is the tone of a conversation that has stretched over five months, with several owners competing to see who has driven the most kilometers without visiting a garage.

How Many Kilometers Can a Mazda Last?

Testimonials are piling up. A 2007 Mazda 6 diesel has reached 580,000 kilometers with zero engine failures, apart from a 180 euro turbo valve replacement; the starter motor and radiator had failed earlier, which is normal at that mileage. Another Mazda 3 from twenty years ago is at 600,000 with just one clutch change. And a twenty-year-old Mazda 6 with 200,000 kilometers hasn't had a single problem. Japanese reliability, they imply, is in a different league from European cars. The real range is from 200,000 to 600,000 kilometers: a threefold difference that no one bothers to explain, but which fairly accurately represents the lottery of any used car.

Japanese vs. European: An Amendment to Stellantis

The start left no room for doubt. A new owner raved about his Mazda and dismissed Stellantis with disdain: soundproofing 9 out of 10, seats 8, an engine without a turbo that takes time to accelerate but on the open road is, literally, like a flying carpet. From there, it's the classic Spanish sentiment: the brand you own is the best. Some argue that the interior of the Mazda 3 is more beautiful than that of a current Mercedes, with its giant screen and colorful lighting. And some reply, without any elegance, that it's just consoling oneself.

Japanese Diesel Doesn't Play in the Same League

Here, consensus breaks down. The fruta for being eternal belongs to the petrol engines; Japanese diesels, several warn, are the exact opposite. Someone driving a Volvo V60 diesel with 385,000 kilometers summarizes their conclusion: Japanese diesel, bad news. Fuel consumption also divides opinion. A 186-horsepower Skyactiv-X model reports 6.8 liters per 100 km at 120-135 km/h, while another recalls that the 150-horsepower 2.0 petrol engine drank like crazy.

Electric Cars and the Chinese Hand That Changed Everything

The conversation shifts to electric cars, and two viewpoints emerge. One argues that the switch to electric isn't convincing: two acquaintances who bought one sold it in less than four years, claiming it was the panacea, and now all they offer are excuses. The other points out that four years is nothing for a well-maintained car. The Mazda 6e enters the discussion, along with the fine print: the brand has partnered with Chinese companies—Changan and CATL—to survive, and the result is described as a product for Chinese consumers and screen enthusiasts. The combustion-engine Mazda 6, the car of yesteryear, is no longer manufactured. Some are even paying 29,990 euros for the new CX-5, the cheapest option.

The Myth Cracks: Electronics Don't Forgive

The discordant note arrives in the final stretch. Buying Japanese no longer guarantees reaching 500,000 kilometers without a alucinación to the garage, according to the more skeptical view: it guarantees, at best, a slightly lower probability of a major breakdown. The myth of invulnerability would have died with electronics. Recall notices are mentioned, though not verified in the conversation, for the Lexus LX 600 due to software failures in the transmission that could damage the mechanics, problems with valve seals in 2025 2.5-liter turbo Mazdas that increase oil consumption, and a string of warnings about Nissan. This serves, at least, to temper the adulation.

And the detail no one expected. Mazda is not a Japanese surname: it owes its name to Ahura Mazda, a divinity of Persian Zoroastrianism. In other words, ancient Iran. The Strait of Hormuz is named after the same deity. Hundreds of messages discussing reliability, fuel consumption, and touchscreens, and it turns out the car in question bears the name of an Iranian god. The owner of the indestructible Mazda 6 probably didn't know this either.
