I took my rts in for first service. They called me on Friday and said it was ready.I went to pick it up on saturday, I got there and the frunk was open and the battery was gone the service manager told me one of techs had left the key on. They gave a new battery so I wound have to wait for them to charge the old battery, good for me bad for them. The service cost was 238 dollars this was less than the cost on my 2013 sts.
