Low brake power light, RX not starting?

Mine is 2016 RX350. I have already replaced the brake booster twice at two different dealerships. Now after 6 months from last replacement, it's coming back again! My wife was driving the car while I was out of town. She couldn't even start the car after parking for only half an hour for shopping. She thought the battery may have some issue. It turned out the problem was still the brake which lost all the vacuum and she couldn't press it down deep enough to start the car. I am so disappointed at this point!

There have been some brake booster problems and it is covered under warranty. Need to go to service.

Still uses a plunger type switch mounted on the brake pedal. There are pressure sensors in the booster and abs unit for the fancy parts of the brake system. But for starting, the stop light switch is the key component.

Has anyone else had issues with their brakes? In December shortly after purchasing my car it began throwing a "low brake power" light in the mornings. I would get in and the brake wouldn't go down to allow me to start the car. I was able to override by holding the start button and after the car was driven it wasn't an issue until the next morning. I took it in and they replaced some tube that was leaking. 4 months later I'm having the same issue. I get in the car and the brake refuses to go down to allow me to start the car. Back to the dealer I go..........
Ken Shaw Lexus told me "wait 10 minutes, then it will start; malfunction". It does not start. I cannot even shut off power right now. Complete malfunction. And I live 5 minutes drive from Ken Shaw, but I still forced to call Lexus Roadside Assistance. Ok, I'll call them and will provide my feedback on Ken Shaw Lexus.
Thanks a lot.
Never ever buy Ontario built Lexus again.

Low brake light, not starting after “fix”?
Have brought my car back to the dealer 3 times...they won’t take it back in anymore because they state there is no fix at this time. I have a 2017 RX 350 that I got in May of 2017. Has anyone had success with lemon law because of this problem?

Better description please. What is a "low brake light"? Do you mean low brake fluid? Or low brake pressure?

Rx350 Starting issues
When I attempt to start the car in the morning, I get an error message that says “low brake power, pull over to a safe location, contact Lexus”. The car has been in 3 times, been “fixed” once and now I’m told there is no other fix. I have gotten this error message 20% of the time I have tried to start the car. Just wondering if anyone has pursued Lemon Law and what the success rate has been.

The computer responds to low battery voltage by sending error messages for some reason. On my LS460, I got the brake failure message so I pulled into an empty parking lot and tried them. Brakes worked normally so I drove to dealer. New battery fixed issue. This is not related to the brake booster leak issue. If you have enform subscription, car will start with remote even when booster pressure is low.
