Faults:

It is the most well-known failure. Chain stretching and guide wear cause a metallic noise upon startup or at low RPM. The variable valve timing (VVT) system is also prone to failure.

Due to direct injection and the turbocharger, the engine may consume more oil than normal or develop leaks. The turbocharger's restrictor bolt can cause lubrication issues.

The factory mounts are flimsy and tend to give way over time. Additionally, the rear differential bushing is soft, which can place excessive load on the drivetrain during hard acceleration.

The bodywork lacks deep galvanization, so it is vital to inspect the rear subframe, engine bay, and underbody for rust.

General Comments:

The Mazda 6 MPS is a high-performance variant of the mid-size Mazda 6 sedan.

The exterior design of the Mazda 6 MPS also reflects its high-performance nature. It features a sporty body kit with unique front and rear bumpers, side skirts, and a rear spoiler. Additionally, it is equipped with larger wheels and tires, as well as a stiffer suspension system to enhance handling and performance.

Inside, the Mazda 6 MPS boasts a sporty cabin featuring ergonomic front seats, a leather-wrapped steering wheel, and aluminum pedals. The car also comes standard with a high-quality sound system, automatic climate control, and a navigation system.

Overall, the Mazda 6 MPS was a well-rounded sports sedan offering impressive performance, elegant styling, and a comfortable, well-equipped interior.

Let's look at the car's downsides.

The main issue here is rust. This occurs primarily in cold climates (such as Sweden), where corrosion is excessive—specifically around the subframe and door sills towards the rear of the car.

The paint is very thin and prone to fading if not rigorously maintained and cared for.

As for the interior, there are faults in the climate control system—ranging from issues with air recirculation to the air conditioning simply failing to respond to commands.

The seat stitching—especially on the driver's seat and particularly in leather models—can come loose and break.

The leather itself can also wear out quite quickly if not properly cared for.

Small lights behind the air conditioning controls may go out, but a light tap usually fixes the problem.

In general, if well-maintained, kept in its original condition, and driven carefully, the MPS can be an extremely reliable and trouble-free car.

The problem is that finding a project management service provider that meets those requirements is extremely difficult.

Problems with the PCV system cause the engine to run with a lean mixture—much like occasional issues with fuel injectors or fuel pressure—not to mention that excessive turbo boost or a poor engine map can also lead to a lean running condition, potentially resulting in burnt valves or even piston failure.

For anyone looking to buy a car like this—a sports car that is already over 20 years old—the recommendation is to find one with a complete and exhaustive service history, one that has clearly been meticulously maintained throughout its life and shows no signs of abuse or neglect.

This applies to any car, but given that the Mazda 6 is a delicate vehicle requiring significant maintenance, it is always preferable to own one that has been thoroughly pampered by its previous owner.

Faults:

Power steering fluid leaked once due to corroded piping. Was replaced with a new part which had a rubber covering, Mazda had redesigned the part so this problem will never occur again!

Something felt loose inside the driver’s seat (backrest). I could feel it when going around corners really quickly, but none of the mechanics at the dealer could ever feel it!

Had slight rust around the rear wheel arch inner and rear bumper split. This is a common problem for the station wagons sold in Sweden and Mazda fixes it under their 12 year rust warranty programme.

One of the power windows (rear left side) would not work on occasion.

Driver’s side door mirror did not heat up (at least not as fast as on the other side).

Heated seats (front) were very poor. This was rectified on later models, but we had to suffer cold leather seats during harsh Swedish winters!

General Comments:

Fantastic driver's car. It handles superbly, has well composed ride and even the 2 litre engine is very responsive. Gearbox is very good as well, with a precise, accurate feel.

Road noise was rather high, especially with winter tyres. But then again, small price to pay for such fine cornering and handling capabilities!

The station wagon is very spacious. Luggage area is huge and has a smart automatic system for folding down the rear seat backrests.

I was tempted to buy the 2.3 version with the nicer 17" wheels, Bose stereo etc. but chose the 2.0 instead as I preferred the feel and handling of this model despite the smaller engine.
