UPDATE: Dealer said they checked the battery and it was healthy and holding a charge so I must have left something on that drained the battery. I explained that when the car first wouldn't start that morning all the dash lights were on and headlights were flashing but later that evening when I tried it was obvious the battery had been discharging throughout the day because everything was much dimmer. I double checked that morning and there was definitely not something left on. Now every time I get in the car I'm waiting for it to not start again. I can't believe I'm having to worry about it with a brand new car.I've had my 2020 Rav4 less than two months and have only put 1100 miles on it but it's been sitting in my carport since this morning with this same issue. I was hoping to find a simple answer here but now I guess I'll be calling the dealership to come get it and maybe find a permanent solution. I know there was nothing left on in my car last night because I went out to carport several times throughout the night and never saw any lights and I don't have any seat warmer/cooler options. I'm very disappointed to have a brand new vehicle and yet I've been stuck all day. There's no excuse especially with the amount of money I paid for it. I bought a new car because I need something dependable being in the country alone and thought I made a good choice with the Rav4. Sure wish I had known there were starting issues with them before I purchased it. I'll update after dealer picks it up and hopefully fixes it.
