I have had this problem since I got my car. Happens every single time I haven't started the car for 3 or more days. When I took it to dealer they claimed they couldn't duplicate the issue and I simply didn't know how to start my car properly. They were actually quite condescending. Will push the issue when I go in for my first oil change in about 2,000 miles. In the meantime I simply try 4 or 5 times until the car cooperates and eventually starts. Very disappointing for a brand new, luxury car with all the bells and whistles!! Shame shame Lexus. You screwed up.

Have you tried to record a video of this problem and show the dealer? I had a similar issues with starting a car (previous Honda I owned) and dealer finally believed me when I showed them a video.

I had this issue last week. I jump started it and drove it to the dealer for an unrelated scheduled service visit. I was dead at the dealer after they serviced it and went to start it up.

They put a new battery in and told us that the car needs to be used often enough and on long enough drives to keep the battery fully charged. Whenever I check the vehicles status with the Enform App, it shows that it is transmitting data. We have less than a 1000 miles on the car! This is not the first car we have had by any means, lol. I think there IS a problem related to the electronics and communications that slowly, continuously drains the battery.

It's a bad battery. Get it replaced. Had mine replaced under warranty at 4000km because of same issue. They told me they tested the battery and it was fine but replaced it anyway just to make sure.

I have not had any issues since.

I would tell the dealer you want to meet with the area Lexus rep. Not sure why the dealer does not want to escalate unless they don't want to admit their troubleshooting and research skills are not at a level they need to be.

You might also consider trying another dealer.

THAT IS RIDICULOUS!!! I live where I can walk to most places, so we only drive the car a few days a wek, sometimes not driving it for WEEKS if we are away. Taking delivery of new '17 tomorrow - this is certainly making me nervous.

I have had the same issue about 4 times in the 2 months. My car has about 9500 miles. It's a 2017 RX 350. The brake pedal would not depress to start. A warning light showed quickly essentially saying "parking brake low pressure. pull over (don't recall final details)". Could not get picture. Then the car went ahead and started and the brake pressure apparently returned and I was able to depress. This happens when I first start in the morning. And in the last case was sitting 2 days in my garage. It's about 50 degrees F in the garage. Once it's started it's not a problem. It happened right before my 5000 mile service. Dealer found so error codes so couldn't validate my claim. Will take these comments and return Feb 10 2017 for my scheduled service and report this error again.

A few weeks ago, my RX350 failed to start engine and showed a message something like "Low Brake" pressure. The start button produced no noise at all, I tried it about six times with no noise from the starter. Then after a few seconds I tried it again a few times and the starter seemed to want to engage with a ratchet type noise. A few tries later, the engine finally turned over but did not start. Held my breath, crossed my fingers and tried again and the "Engine" turned over and ran OK. Cancelled AAA and drove to the dealer for replacement of the "Brake Servo". Only took a week to get the part and install, 2015 RX350 loaner provided at no cost. Gave me an opportunity to revisit the 3d Gen RX350, and I've decided I like the 4th Gen better.

Mine had the problem last year after drove the new car for only two months. The dealer had replaced the brake servo. Just in a year, for the last week or two, the same problem is coming back again!!! Unbelievable the Lexus parts is so unreliable!!! I am going to get it replaced again but I start to worry about this.

I've been driving my mothers RX and this is the second time a notification has come up once you put your foot on the brake to turn the car one it says something about brake being low but disappears to fast to read. I'm not sure exactly what it is and neither is the dealer. I was just wondering if anyone else has been getting this notification

ggebhardt

Not sure what year RX but there were some brake pump problems with the 2016/2017 models.

I would get get it back to the dealer. Brakes are one of those things you do not want to fail.

If it only happens when you start the car, it's most likely "Depress brake and then start engine." If the error was "Brake Fluid Low," it wouldn't go away like that.

Jenesh14

it's not that one, I get an error message about brake being low it's a quick message but I can't start the car unless i force the pedal down then if I turn it off and try turning it back on the brake pedal isn't stiff anymore and it starts just fine
