Just bought this CX9 with 62,000km and recently when driving on the highway I get this humming sound at speeds 100km+. Sound like it's coming from the engine. Brought it back to the dealer (30days used car warranty), had them do a wheel alignment since the vehicle kind of pulling to the right a bit. Also suggested to check wheel bearings but was told no issue there. Still have to reschedule with their service guy to test drive on the highway at higher speeds during off peak hours with less traffic. Anyone here experienced the same issue with the CX9 and and would appreciate what was done to get it fixed? Thanks.

 

Welcome to the forum


I get customers all the time with humming noises.
You are really not giving anywhere near enough information to even begin to give a long list of things that you are hearing.
When you go to the service shop go on a test drive with the service rep and when you hear the noise let him/her know.
