johnorhah3 Posted April 23, 2020 Share Posted April 23, 2020 I have a 2011 Lincoln MKZ with 123,000 miles and when i start it up it makes a screeching sound for about 2 seconds and then it goes away and the cars rides perfectly fine afterwards. Any idea on what is causing this screeching sound upon startup? Quote Link to comment Share on other sites More sharing options...
