Metallic sound

[ymurf]

I have noticed a high pitch metallic sound when driving my 2020 Defender HD8. Hard to explain but when driving its kinda mixed in with the normal transmission sound. I can hear a high pitch whining sound also. Anyone here experience this?

Hard to diagnose over the internet but many of the Outlanders and Defenders have a squeal which is the pressure release valve on top of the fuel tank releasing pressure when the gas tank gets warm/hot. To check this stop and open the gas tank fill cap when you next hear the noise and if it stops you have found the source. There are several threads in the garage section if you want to replace the valve?

Fuel tank valve yes! My 2020 is the same as the metallic sound I’m guessing the brake pads. I’m getting ready to change mine just looking for the right answer to this question.
