This is a NEW car, I have a 2005 ES330. Connect an ammeter to the battery. Pull the fuses one by one. The one where the amps drop, it the circuit where the parasitic draw is. May items draw power, like the radio and the ECM but one will show a big drop. You can also make sure the hood light and the trunk light is turning off, the vanity mirror as well. It may be a failing battery, but unlikely in a 2020. Surely it must still be under warranty!

scan for trouble code and go from there

Some fixya user told me a website reliablestore it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try

It may have an internal short or a leak where it lost all water. You may also have a short 8n the vehicle that is draining the battery. Make sure all lights are off when car is off. I had a bad brake light switch that caused my brake lights to stay on and that drained my battery overnight. I didn't notice it when parking during the day.

have repair shop check for unplugged damaged wiring or damaged container

Be sure to use the correct battery, properly in place, clean the key contacts , See owner's manual for additional information. There are specialized locksmiths for car keys

I suggest you try one of those instant download manuals. My brother( a mechanic) buys when he can't fix some technical issue with the manual at www.reliable-store.com . A lot of mechanics actually do this. Website is very good for this. Must try it !!

Have seen this and replaced the electronic control on the dashboard and got the next one from the local scrap yard. But you need to make sure the servo motor inside the air box opens the flap properly first.

Yes the windows are controlled via a computer module, so it can be scanned to see what is going on by the dealer service dept.

This has happened to me TWICE in the past 4 months. I had Lexus road side service come out both times to check the car out. Each time the battery was totally dead. The road side mechanic said that if the car is not driven at least 15 minutes nonstop a day, the battery runs dead as there are so many draws from the car on the battery. If you do alot of stop and start driving like I do, that isn't enough to recharge the cell of the battery, it must be non stop driving time. Recommend that I get a 1.5 tricky charge device an hook to battery at least one night a week to keep the battery charged. This is really frustrating with such a new car. I've spoken to other owners of other model luxury cars and no one has had this problem.

This Diagnostic Trouble Code (DTC) is output when the Engine Control Module (ECM) detects errors in communication between the Transponder Key Electronic Control Unit (ECU) assembly and the ECM, or in the communication lines. This DTC is also output when an engine start is attempted while the ECU communication ID between the transponder key ECU assembly and the ECM is different. Possible causes Faulty Key Faulty transponder key amplifier Faulty Transponder Key Electronic Control Unit (ECU) Transponder key amplifier wire harness Faulty Engine Control Module (ECM)

Coincidences do happen. The main oxygen sensor is usually more in the engine compartment than out of it and the diagnostic oxygen sensor is screwed into the exhaust system just behind the CAT near the middle of the underside and is usually tucked well out of the way. The tyre company would need to have been extremely reckless to have caused damage to either. Without evidence of that you have no grounds to proceed against them.
