I have a 2019 ram bighorn . Got off work and started truck and battery seemed weak and turned over slow, but it started. Then the check engine and esc lights came on. I put it in drive and went to leave and it would not shift out of first. I took battery off to be tested and it was good just needed charging. I charged battery and reinstalled. Then nothing. No power anywhere. No horn no windows no lights nothing. Had it carried to dealership as it is still under warranty. It has been there for 9 weeks. They can't figure it out. I have also contacted ram customer care and got them involved. And still can't fix it. Has anyone had this issue. And how long can they keep my truck. They didn't even give me a loaner vehicle. I have one borrowed from a friend. Any advice would be appreciated.. thanks in advance..
