Car left us stranded 12 V battery completely dead had a lot of difficulty trying to get it started. The unfortunate part is I got rid of a 2023 Lexus RX 350 H for the exact same problem could not get resolved after installing five batteries. Now we’re going down this road again.
I bought this vehicle last Thursday, The new Lexus we only drove it three times, but all power down. The first time we were about to go to work, the whole vehicle no power, so I checked the battery, it was 10 Volts, so I used my CRV battery turned on Rx350, it's working, Second time, when I arrived my work place, I turned off the new vehicle, The Whole power down again, After I checked the battery, it showed 12 Volts, after I checked the battery, the power came back. The third time, After working, I got totally locked outside the RX350, I tried so so many times, The Whole power was gone again, so I broke the handle and used the key get into the car, and checked the battery, still 12 volts, after my checking battery, the power back again! So I am sure it's not only the battery problem, but also Power management module something wrong with it, or a module named 89690-0E011 Is damaged , I am very sure the new RX350h needs very very professional technician repair, This vehicle has serious safety hazards and poses a threat to life and safety.
Battery on car under 6 months old and fewer than 3,000 miles was DEAD after not being used for one week. Weather was not an issue, as car was parked INSIDE of residential garage.
While driving, the instrument panel went blank. I believe it is not safe to drive with no instrumentation or knowledge of your vehicle or speed. The dealer confirmed it needed a software update and performed this yesterday. We were not advised of this needed update, no recall or no communication from the manufacturer. We should be advised when something this critical is needed.
Brand new vehicle 12Volt battery failed after 3 months of operation. Please note same exact scenario occurred with a 2024 RX450 in December, 2024… Lexus repurchased that vehicle via the Lemon Law
