Welcome lights are going on and off by themselves throughout the day and night. I have had to call Lincoln roadside assistance 3 times for a jump start because it keeps draining my battery. It's been to the dealer 4 times and they cannot seem to fix it. They have updated the modules and replaced the battery but I got it back last night after being at dealer for a week just to have my car performing a light show for my neighbors again. MKC is back at dealer today and I am praying it gets resolved finally. I have wasted so much time and lost work because my battery keeps dying on me. Very frustrating!!!!!
