Battery Issues
Has anybody had battery issues with the SUV?
Had to jump start the car twice since I purchased in May.
Once was after I was playing with the setting just after a drive for 30min with the lights on. I was just adjusting the chairs.
And the next time was after I had not driven the SUV for 2 days.
It's a fully loaded Fsport and had a Dash cam installed from the dealership. The dashcam has a parking mode but I have it set to cut off if voltage goes below 12.4.

Pretty sure it's the dash cam causing the battery drain. Try unplugging it to see if your battery keeps its charge for a couple days. Take it back to the dealer and have them take a look too. They might swap the battery out for a new one. It can't be good for the battery to have these complete drains so often.

I was riding with a AAA tow truck driver a few years ago after calling them for my mother-in-law's car. Since I figured he had quite a bit of experience with batteries, I asked him what brand he'd recommend (Interstate), and then he said the make he gets the most battery calls on was Lexus, he thought because of all the electronic systems in it that are kept running 24x7. (Have you noticed you can connect via Bluetooth to the car even when it's shut off?) That what made me start checking the water in the battery every month, especially during the hot summer months.

I will take it in to the dealership to check the battery and the wiring. Maybe with the summer heat everything expanded and created faulty wiring contact draining the battery.

Turn off your car and your phone's Bluetooth, then while within range of the car, turn the phone's Bluetooth on. After a few seconds it will connect. At least mine does.

I still could not see a dash cam draining the entire battery overnight. They tend to draw very little power and many work on AA cells. Maybe the OP has one heck of a heavy duty camera but a car battery holds a good bit of power.

Well, forget this. My new phone confirms Bluetooth connections in a different way than my old one, and so Bluetooth doesn't connect after all, at least for me.

A little off topic, but i want to charge the battery a bit and my charger has settings for STANDARD or AGM battery. Do you know what kind of battery we have? I know my Audi has an AGM battery, but they're typically more expensive ...

Oh yes. it will. If parking mode is on and recording all night. I'm using Power management on my dash cam so that when voltage drop down to 11.6V it will shot down the dash cam

Have left my dash cam and radar/laser detector on for more than 24 hours many times and has zero effect on the battery. Yours must be drawing so serious amps.

I have found out that Toyota/Lexus do not put the best batteries into the cars from the factory. The best ones from factory were when they put Panasonic batteries in. I do not believe the new generation RX uses Panasonic anymore (at least mine does not). I think they are standard batteries and not AGM, also.

then you need to get another dashcam. Like I said I have left mine running for several days along with the radar/laser detection system and it started right up.
