Mazda 6 List of Solved Issues
After driving my car for more than 3 years, I thought I'd write and share what I hope for to be a reference for the 3rd generation of Mazda 6 solved issues. I hope it's going to be useful for this website's members and general online readers as well. I kindly urge members to contribute to this thread in order to build a very good source of solved issues.
My list is not classified under any particular type and it may fall under any classification (e.g. mechanical, electrical, electronic etc.)
1- Cracking noise around and under the armrest.
Turned out the noise was coming from exhaust hanger rubber which needs greasing or any type of cleaning spray such as W40.
2- Suspension noise
This issue is common, and I managed to solve it by replacing the lower control arms and they don't cost that much. You can try spraying the bushings with with W40, or grease them, if that doesn't solve issue, replacing the LCA is your final call.
3- Continues vibration while driving around 110-130 km.
This was the most annoying issue I faced and it gave me headache to eventually solve it. I tried many ways starting from balancing tyres to replacing wheels and replacing bearings. I ended up replacing the axles and that solved the issue.
4- Changing ATX Fluid
Although Mazda doesn't recommend changing the fluid or operating any interval changes, I'd go with the views that recommend changing the fluid around 100 km. I Changed the fluid at 125 km and I have to say that ATX movements and changes became smoother. Flushing the fluid after 100 km maybe potentially dangerous which I wouldn't recommend.
5- Oil leak from the Oil Control Valve on the top of the engine.
If the Check Engine Light didn't come on, you most probably need to change the seal only, which requires removing the engine's valves cover and I recommend changing the rubber gasket as well.
6- A/C not cold enough.
First you need to start with the basic and cheap things such as the A/C filter. I found out there was a tiny leak coming from the Low Pressure Valve, and I solved it by replacing the core valve which is the same as the core valve for tyres. To do this, you need to refill the Freon.
7- Cracking noise after replacing the brake pads.
This noise usually appears when replacing the pads and not greasing the caliber's slider pins, and in most cases this noise would disappear after driving for few days.
8- Oil Leak from the oil pan drain plug.
The drain plug seems to be designed to be used once, and the ultimate solution to this is by replacing it with Fumoto Drain plugs, or you just replace the washer with a better quality one.
9- Warped Rotors
This can be solved by getting better rotors from either EBC or other fine brands.
10- Leak from the engine's belt tensioner
It's been leaking since the first year of having the car, but finally it decided to declare the termination of bearing the belt's movements, the belt started squeaking and the engine started roaring when first driving in lower gear. Replaced it with engine's belts.
I tried to gather all I remember of issues that I managed to solve, and I hope it's useful.
