Faults:

Small oil leaks at the valve cover gasket.

The infotainment screen may frequently restart.

Carbon buildup and premature failure of the ignition coils, causing misfires.

Noises in the front suspension (stabilizer bar bushings) and vibrations or squeaks in the rear brakes.

General Comments:

The car is a mix of comfort, safety and other sporty features.

Inside, it has all the luxury you could ask for in a premium car, even though it's a Mazda: top-level components that don't wear out over time, and a superb ride comfort that makes it extremely pleasant to drive.

The 2.5-liter engine isn't economical, but the important thing is that it's extremely reliable if you follow the manufacturer's maintenance recommendations. Despite being an automatic, it has a distinctly sporty feel and accelerates really well, which is a highlight in a family sedan. The engine is more than adequate and has just the right amount of power for this type of car.

In particular, it's an excellent car for long trips, not only because it handles very well on the road but also because it consumes significantly less fuel at a constant speed. The automatic transmission maintains a steady speed very well, keeping fuel consumption low.

Looking at it today, it doesn't look like a car that's already 11 years old. If you take good care of it, you can keep it for decades. Buying it might be expensive, but given its high reliability and regular maintenance, it's truly worth it. It's a car that will last you a long time without giving you any major problems.

In short, it has all the characteristics that have always been said about Japanese cars.

Faults:

Nothing but wear ad tear parts replaced. No major problems in three years and 30K + miles.

General Comments:

I had a diesel Mazda 6 before this car and it was terrible. Read the other reviews on here and elsewhere to understand why.

But the reason I kept with Mazda all this time was it was a one off - I have had a Mazda since the 626 saloon days in the 1990's, and the petrol ones were always OK.

Being a 2.0 you cannot expect much more than around 37 mpg, but it will do more than 40 mpg on a long drive, which for petrol is impressive.

The car is smooth to drive and has plenty of power. Gorgeous looks inside and out. My car is red, common and best color.

Interior is as comfortable as it gets. High step up in quality from previous models. My car is ten years old yet looks brand new.

If you see a low mileage petrol Mazda 6 of this generation at a good price, go for it, you have no worries reliability wise, so long as you avoid the diesels.

Faults:

Not much over the last couple of years I have had the car. Last week however the car became sluggish and the engine light came on. Taking it to a diesel specialist soon as my local mechanic was unsure, hopefully nothing too serious.

General Comments:

Sporty, good looking, fun to drive, and very spacious estate tourer, the Mazda 6 is a fun family car to own.

Engine is punchy and economical.

Seats are perfect for my height. Love being in this car. The car has all the electrics you would expect. Comfortable.

It's a very good , but no better than a Vauxhall Insignia or Ford Mondeo or whatever.

Not too confident in it lately though - I have read horror stories of the diesel engine problems in these cars, hopefully my problem will be something simple. But lately I'm thinking I should have went for a petrol engine Mazda 6...
