Brake has been sticking last couple of weeks so that I had to pump brake to release to start. This morning I went out to the driveway and could not get into car with either remote or by using blue link on my phone. I used the manual key but could not release any other doors or lift gate. No lights, hazards, radio no nothing. I have had a few dead batteries and never had a car that dead overnight. I drove home from work previous night and I was outside after dark next to my car, no lights left on. I called roadside assistance, first guy said he thought there was a short, parking brake would not release and car still did not start. A different tow truck had to come with dollies and it was towed to the dealer. Dealer said it was a dead battery at 4918 miles! thankfully I was at home and the heat index was not at 105 degrees yet for the day.
