Abs light comes on and goes off. Brakes are starting to fail when light is off, not when the abs light is on. I am going to take it to the dealership for inspection.
2003 mercury mountaineer has rear differential issues. Loud humming coming from back end. Potential failure is possible at anytime which can result in locking of back wheel.
This week the latch broke on the outside of the window and the glass fell again. Lincoln mercury dealer in hyannis charged me for the part! This all is directly related to the earlier recall I would believe. The dealer says no.
