Less than 6k on the ODO, and this is what happens when I go to slow down today. I had to pull off and have the NX towed to my dealer. Remote started it to cool it down, ran for the 10 mins, then drove maybe 2-3 blocks. Put my foot on the brake and all of these started coming on. No car-wash before hand or anything... Turned the car off then back on, and they went away. I thought it was my imagination that the braking wasn't as strong as it used to be. My NX wasn't affected by the ABS actuator recall either, since its build date was 9/15... Blind Spot Monitor was also showing on and off, too. Brake Hold system as well.

Any ideas?

Wow, lots going on there. Never came across this personally nor have I seen this in the forum. You may be the first. Glad you were able to safely stop.

I wonder if unplugging the battery would do the trick or if it would just be a temporary workaround. The dealer should be able to read the codes to determine root cause. Did they say anything?

Thanks Corrado, it was a major bummer today to say the least. Once I pulled off and took pics of all the warnings to show my dealer, I turned the car off and back on. The warnings were all gone but braking power still wasn't 100% of where it was two weeks ago. So I drove the two blocks back home and called Lexus.

My dealers service department is closed for Memorial Day (only sales was open) so I had to call Lexus Roadside to arrange the tow and drop off. I should hopefully find out tomorrow what's going on with it, once they're able to get in there. I know with other makes I've had, when the TCS off, ABS, and Slip lights have come on, that's something wrong with the ABS system. I'm presuming it's the same on the NX.

Funny that Lexus was so concerned with the braking system on the owner surveys. I think they know it's not up to par with their standards. We shall see...

:UPDATE:
So after driving 10mi with the laptop connected to the car, they couldn't find anything wrong. On the way back to the dealership it started to rain. The NX turned of Traction Control, and started popping codes (thankfully.) They were able to trace it to the right rear wheel speed sensor. Which makes sense why it shut off AWD. New part comes in tomorrow.

Service told me this is the first Lexus where all of the computers are connected. So if one malfunctions, it can spread. (I presume he is talking about a CanBus system?) unlike the older Lex's where the various computers are mostly isolated. If it hadn't started to rain today, they never would have found the culprit. I'm just worried that
A) This is a signof a bigger problem, not a cure
B) It was dry out when this happened to me yesterday and has been for days. So no water or slippage triggered my major episode
C) My infotainment system is still on the fritz, and they just keep telling me to talk to a technologist or delivery specialist since I have all the latest software updates. Wouldn't it be a hardware issue then?

Idk.

Everything connected and the computer running everything is what worried me prior to purchasing a Lexus. At least you were able to safely pull to the side and stop which was my biggest concern.
Hope everything is fixed soon.

typocl

what issues are you having with the infotainment system?

MikeW83

Thanks Tomo, hopefully tomorrow!

typocl, the most recent bugs are the constant "Audio Player Disconnected" "Phone Disconnected" followed by them both reconnecting messages. Then last week after I updated the software, I lost my HD Traffic signal for 2 days. It was set to display, but there was no 3cars and the HD logo on the screen. I would have to launch the Enform App so the car could pull from my cellular data. Then it just magically came back on.

Audio playback will also randomly stop and disconnect at times. The bluetooth will still keep the phone part connected, but the player will just stop and disconnect. I have to manually go back in and reconnect my phone for audio. This has happened for the last couple of months now. Twice the system has just shut off while I was driving, and rebooted. They don't seem to want to give me a new radio, they just can't duplicate my problems, and want me to talk to the delivery department to "See if you can pair your phone a different way."
Yeah, I'm sure that's it lol

Disconnecting and reconnecting my phone did resolve my missing directory problem, so that certainly might help. The problem has never returned for me so while I was skeptical, it does seem to be resolved.

MikeW83

Been there, done that. Keeps coming back. My directory has never vanished on me though. That's a new one I haven't heard before. I hope it stays resolved for you!

As far as your phone audio disconnecting, do you have it plugged in to the USB port to charge? I ask because when you plug an iPhone into usb it goes into what I call "ipod mode". It thinks you want to play your music through the USB. If you are, use the 12V port to charge. It won't interfere with Bluetooth and will charge faster. That and reboot your phone every few days if you don't already. A hard reset fixes 99% of iPhone issues I've seen. Because most people never ever power off their phones.

MikeW83

When I got the NX, I was using the 12V to charge it, and bluetooth for calls and streaming music. I had a ton of issues with the music streaming staying consistent, so my dealer was the one who told me to start using the USB port instead. That worked just fine for a couple of months, but as of late has created more headaches. (It is actually nicer to use the USB, since it pulls the album art off of my phone. I don't end up seeing the generic genre icons from Gracenote, or the super outdated artist pics that way...)

I just picked up the NX from the dealer last night. Since all of the systems are interconnected, I'm going to see if the "short" in the sensors may have somehow been interfering with the infotainment. I'll update if that seems to have solved some of the gremlins running around my wiring

Mr645

I had a VW that threw up several codes, turned out that a sensor in the steering system failed and other system had a fit because of the faulty data. The error codes were all from systems besides the failed sensor

MikeW83

Gotta love CAN bus systems eh :P My Audi would do that too... Mainly if something failed on the air suspension. The MMI controlled that, and would really freak the car if air lines froze up in Winter, for example.
