My 2021 RX350 wouldn't fully start and displayed warning message stating "low braking power", so I thought that the programming was preventing the car from starting due to a braking issue. But, the car wouldn't turn off, either. It stayed in "ignition ON" mode. I was parked inside a parking garage of an airport on the 3rd floor and it was almost 8pm. I called Lexus roadside assistance and spoke to 4 different persons who could not identify what was wrong nor why the ignition wouldn't turn off AND they couldn't get a tow truck into a 7 ft max clearance airport parking garage. At this point, all of the various alarms are flashing on the dashboard in a continuous cycle. I'm on the East Coast, so I started calling Lexus service dealers on the West Coast since it would only be about 5:30pm. I spoke to 2-3 in CA (no one new how to get the car to turn off) and 1 in OR who said to disconnect the battery, but I had no tools to do it. I considered getting the car pushed out of the parking garage but with two down ramps and messaging stating that the car essentially had no braking power, it would be unsafe. Two hours later, sitting in my car at the airport, a warning message stated that the vehicle was going to shut itself down due to low battery. The next morning, I called one of our two local Lexus dealer service departments. The first one took a message and never called back (still haven’t heard from them). The second service dealer, Lexus of Jacksonville FL, took my call, found an advisor who knew from experience that a Lexus with battery issues will freak out with all sorts of error messages. But he has never heard of a vehicle that couldn't be turned off. I was stuck in the airport for 3 hours, and I live one hour away, so this was quite an ordeal getting transport back & forth twice. I called AAA (not Lexus roadside) to come to the parking garage the next day and they were able to jump the car, and I drove it to the dealer. They identified a bad battery (3 year old car with 26k miles) and replaced it under warranty. But this was a horrible ordeal. Why doesn't the Lexus programming with all of its bells and whistles, display a message that the battery power is low or the battery needs replacement, rather than telling me the car has faulty brakes or other system errors!! This is POOR programming and messaging. And, why wouldn't the vehicle turn off??? Lexus - - this is a big issue, based on the numerous battery issues reported and the faulty programming that needs to be addressed.

I have the same question. Had anyone replied to this? Or does anyone have the answer?

Hello. The links don't seem to be active. Is it possible to reactivate please?

I have been driving around for a whole year with this same problem....and with mine, the door open light on my Lexus RX350 continually says the hatchback is open, even though it is closed and latched. I will try this fix and let you know if it works. If it does....I greatly appreciate this post and I thank YOU in advance.

None of that worked. Is it possible to program the window regulators with a couple?

Guys I just programmed my Lexus spare key and it was so easy. Wanted to share with you guys. The key is on sale for only 83 bucks directly from manufacturer DORMAN from Amazon so buy it before it gets sold out. I paid 120 for it just few days ago but hope you guys get a deal. Link below. https://amzn.to/3K3PpAG I made a video which I’ll post a link below for how to program. Took me 5mins. https://youtu.be/abJX5JzXp9g

? , 2018 Lexus rx 350 awd drivers side front axle. ? Is there supposed to be end play at the hub ? With wheels off the floor and supported just inboard of the ball joints I am able to move the axle left and right about 1/8 of an inch. When I drive over pot holes I hear a loud clunking sound, have checked all bushings and no issues. Thanks in advance

Service notice AWD system malfunction; 2WD mode engaged

Paid close attention yesterday to the idle on the LS460, 500 to 550 in gear, climate turned off. With climate on it idles at exactly 800, in gear. In neutral or park, climate on or off, it seems to idle at the same 750 rpm. Hope this helps.

Is the AMP the issue fuses are fine navigation works antenna and radio will not power up? bought a used amp still not working is the used amp junk do i order another amp. Other issues that would cause this error message? Thank

I am looking at a 18 450h tomorrow (accepting offers too if you are selling.. near atlanta) I love the car, I love the tech, from what I've seen, I am looking forward to the test drive tomorrow. The one downside I am seeing is it does not have Android auto, seems impossible to upgrade OEM, and aftermarkets are spotty / running old android. Before I get a bunch of responses, "just buy a newer one" or "wait a few years" as someone who is tech willing and the rest of the car is perfect, is there ANY updates or new upgrade kits that actually work. Thanks!!! 🙏

I would like to install a backup camera in my 2003 Lexus ES300. Can I do it and how much would it cost? I also would like to know if my Navigation system can be updated.

Interior Fuse Box Location: 2008 Lexus RX350 3.5L V6 (carcarekiosk.com) This one is in the same generation RX. It doesn't look that hard to access.

Have you checked the water level in your battery? (if it's accessible) If that's okay, how old is the battery? A week battery can cause the ECU to throw weird codes.

2016 LX 450H bagan issuing intermittent LKA warnings months ago. No apparent degrade in performance -- everything works OK. After shutting down, light disappears. No good knowledge of/or guidance from dealers, though other owners report the same symptoms. Very frustrating. Any thoughts/ideas?

I have a very difficult time getting to and seeing my interior fuse box. I am not a contortionist, but feel like I need to be? Has anyone have any suggestions that make this easier?

I recently had to replace my transmission cable bushing at the *BLEEP*er end of the cable. Involved disconnecting my battery. Since then my back door will not open with the key fob or the inside button, also my memory function on my seats and mirror will no work. Any ideas what to try?

I have a 2006 Lexus RX-400h. The climate control switch is broken and it is "stuck" on max a/C. Since I live in FL (near Tampa), it is convenient (for now). However, I'd like to get it repaired without costing me a small fortune. Any ideas? Bill Feeney

I figured it out it was a blown fuse it was the 10 amp dome fuse. There’s 2 fuse boxes though one in the engine bay next to the battery and one in the driver footwell above the e brake.
