2001 Mercury Sable 6 cyl Front Wheel Drive Automatic 137000 miles
I've had this car for 2 1/2 years and have had many issues that I think are related. 1) Security alarm turns on at night if doors are locked. It can be locked all day, but only turns on at night. 2) My head lights will turn off sometimes if the Auto is selected. 3) Right front brake turns on while driving warping the rotor. 4) Radiator fan would not shut off and drained battery. 5) The low coolant light comes on randomly. 6) After a car wash the check motor light comes on and car misfires. 7) Humidity also causes low coolant light and check engine light to come on. No codes are in memory when checked and disconnecting the battery usually clears lights on dashboard. I think it's the ECM.
