I own 2013 Sonata and I’m having the knocking sound coming from behind the area of where the navigation/ radio screen is in my car. At 1st last week it would only do it when I 1st start the car and go in reverse for a minute. Now I hear it periodically. What can this be? The engine? I have had all the recalls (I think) done.
I would suggest having someone check your engine mounts.
Oh NO…has anyone seen Manuel? Wasn’t he last working on a 13’ Sonata? I haven’t seen him since and have been wondering where he went… Good God man
