Brand New MKC - Dead Battery twice in less than a month
I bought my Lincoln MKC off the showroom floor with less than 100 miles on it. Took it home and about 8 days later went out to start it in the morning and it was stone dead. Had only been sitting for about 8 hours after driving for about 20 minutes. Called Lincoln Roadside, they jumped the car, it started no problem. Took the car to the dealership, they claimed it was a bad battery and switched it out.
Brought the car home and 2 weeks later it happened again. Went to the garage to start the car in the morning and it was dead, wouldn't even unlock the doors. Called roadside again, they jumped it and it started. Took it back to the dealership. They have had the car for 4 days but say there is nothing wrong with the car. The battery tests good, all their diagnostics show nothing. They are bringing it back to me today.
Has anyone else experienced this? What is going on with this thing. Way too expensive of a car to not be able to trust it to start up.
The only common thread is both times it happened, I locked the car with the fob (hit the lock button), left it sit overnight and tried to use the remote start in the morning.
Any ideas? Thanks!
