Battery Dead problems of the 2020 Toyota RAV4

Our car sat for 2 days without being used and the battery was dead. Read online many other Rav4 owners having similiar issues, something is draining the battery.

Battery died less than 24 hours after last use. Parked in enclosed garage.

Battery isn't holding a charge. Temps outside are getting colder but not that cold. Don't drive it on sundays, battery is dead dead on Monday mornings. Drive an average of 30 miles per day. Battery was replaced by dealership and still slow to start in the mornings. Now run it idling for 20 minutes Sunday evening to ensure it starts Monday morning.

I have a 2020 Rav4 xle with about 3,000 mileage. The car battery has died twice. The first time it happened, I jump started the car. The second time, I took the car to the dealer but they said there was nothing wrong with the car. I don't understand why a new car would be having these battery problems. Has anyone had any similar problems and have suggestions on how to resolve the issue?.

Rav4 was purchased first week of June 2020. Two weeks later, I go to start the car in the morning and the battery is dead. I had it jumped and took it to Toyota. The dealer said everything was working as it should. I took it home. This morning, three week after the first incident, I go try to start the car in the morning and the battery is dead. The tow truck driver was able to jump and start the car. Since this was the second time this happened in a month, I had the car tow to the dealer for further diagnostics. Something is definitely wrong with the electrical system. Car was parked in the garage over night both times. No lights interior or exterior light were on. No doors ajar to draw power. Radio was turned off. Both fan and a/c was turned off.

I bought a new 2020 Rav4 hybrid xse in January. Two weeks ago, I went out in the morning to drive it and it wouldn't start. The battery was dead. I had left it parked in the driveway with the car locked. The car had 5,400 miles. I called roadside assistance to jump it and get it to the dealership. They ran diagnostics and had no idea what the problem was. They suggested I wasn't driving it enough ?.

My 2020 Toyota Rav4 wouldn't start. It was parked in my garage. A tow truck operator ran a test and found that I had a dead battery. This was surprising because I only had 1,800 miles on this vehicle. After the operator charged the battery, I drove it to the Toyota dealer's service dept. They ran some tests and replaced the dead battery under warranty. They were unable to find out what caused the battery to fail. The technician told me that they had 5 batteries fail this month. I did an internet search and found other people had the same problem with the 2020 Toyota Rav4. They thought that it either could be an internal short in the battery, or else the digital parking brake was draining the battery. This battery problem could be a serious safety problem that could leave people stranded in winter weather.
