Question Asked: my denali makes a noise when driven long distances
August 04, 2013, 12:18 AM
this is not the usual pump or air compressor noise..it sounds like a jack hammer and happens off and on when driving long distances..we have had the suv at the local gmc dealer twice and they have it for almost a month and could not figure it out..this started happening after a new set of tires where purchaed and we did discover that a tire sensor had been broken in the process and after this was repaired we thought the problem was solved but after a few weeks the noise returned..any thoughts on the problem would be appreciated..by the way in the process the dealer did replace the shocks they were leaking and they thought this was the problem..also my wife claims the problem does not occur when using the cruise control.
