Hi, I experience car my has a humming sound coming from the engine also the vibration from the panel when the RPM stayed at 2800~3000.

Not sure anyone here has the same experience as me and please share with me.

At the moment, Toyota machanic has changed the mounting and the front wheel bearing. It didn't solve the problem at all, they have no clue on what's the problem is ? I am so sad with them actually, I couldn't enjoy my car since I bought it. It has been a year they still couldn't solve the problem.

Anyone here know the Customer Service email address for Toyota, Japan ?

Thank you.
