Recently, I noticed there's very weird humming sound coming from rear of cabin after 10-20 mins when driving . It sounds like vibration I think. It disappear after I turned engine off. Other than that the car seems no problem. Miliage is 11500

sorry for poor English btw

Just had this done as well as precaution. I did not have a noise, but a friend did and the flash fixed it. My dealer said they have been getting a lot of complaints about it so they just flashed it without a noise present.

Is this problem common a specific year? I have a 2017 and I think I hear some whistling noise while driving.

There is a high chance of three common things that cause the vibration when you drive the car for few minutes:

1- Dynamo Fan issue. ( radiator or engine ). when a damaged dynamo run faster to cool the engine it couses the vibration.

2- Exhaust system issue ( because of the exhaust hangers or the pipe ) which cause vibration & its usualy happen with aftermarket exhaust system. ( verry common )

3- Engine Mountings are damaged.
