Drove home last night no problems, went to start this morning and car was dead

Dealer won't tow, they have asked me to get it to them. It is a push button start

Make sure the tow is reimbursed IF the fault is due to a warranty item , or , hopefully you have a choice of another dealer in your area. Could call # in owners manual -maybe get to a district or regional manager. MAKE sure you have your bases covered! Check everything in owners manual that may refer to the problem/symptom you have. Do you have a way to test the battery and verify full charge? Just in case , have you checked/tested fuses?
