Hi Edward,

You've not told us which year your car us, but there is a known issue with the 2015 on model on the rear brakes causing noises. The solution is to fit new brake pads of a newer design to the original. Without having access to your car it's impossible for us to know if that's your issue, so best bet is always to bring the car to a good mechanic to look at. Mention the above and that it has nothing to do with wear of the brake pads - it's the design of the originals.
