Vibration and low growling sound in idle and acceleration
I have a 2008 Buick Lucerne with 75,600 miles. It has just recently started
making a low growling noise when in idle and acceleration plus vibration in floor
board, pedal, seat and steering wheel. Have replaced front motor mount now it
is worse. Had the tires checked out and it's not that. Does anyone know what
could be wrong or had this problem and got it fixed?
