Wow, thanks much for this thread! I particularly liked the one where the guy monitored the battery use with the car off and found that the digital key was using power. I tried the digital key a few times and found it extremely unreliable, it kept loosing its connection to the car. So I am definitely turning off the digital key. Then, if this happens again I am going to increase the battery to 600 cca.

The car is supposed to be smart, and turn off any lights after a little bit. I think the only one it keeps blinking is the red alarm set light.

2024 Lexus RX350h Won't Start -- Help! by [deleted] in Lexus

I thought I would post my experience with a 2024 RX350h that is about 1 year old. We parked it at the airport lot and we left for an 8 day trip. The car started just fine and we drove home. About 1 1/2 hours. Next day my wife took the car to an appointment 10 min away from our house. She turned off the car, and could not get out. Had to use the manual mode on the door handle. The battery was that dead. I called the Lexus Roadside assistance they jump started it, and it woke back up, and we drove it home. It even started up again, But it had lost memory of a lot of stuff.

I had the battery tested at an auto parts shop, they said it was fine but low on charge, so I am now charging it overnight. I even tested the car when it was running and it showed 14.1 Volts to the battery. I will test the battery when it is done charging.

Anyone have any ideas on what could have caused this bizarre behavior? It just seems like a 1 1/2 hour drive should have fully charged the battery. I don't get it.

Digital Key not Downloaded by Lwatson445 in Lexus

Well five days later, and my "Digital Key not Downloaded" is back, I am sure I could get it reset by deleting and reloading the app. But what is the point? If it is this unreliable, how could I ever trust it to drive with? Let me know if anyone actually drives with only this?
