Intermittent behaviour on new 2021 RX450h: voice recognition and haptic feedback (and other things...)


Recommended Posts

Hi All,

On my third Lexus (first RX) and the first time I have started to engage in these forums.  It's nice to meet you all, but unfortunately I'm writing because of some issues...

I thought I had solved most of my problems (due to a corrupt memory stick... as I added to this thread yesterday... and the problem is certainly less frequent at present than it was last week...

 

...but it seems that on starting the car this morning the problems came back.  The voice command system was not recognising the usb stick  ("play album <name>" and the car responded, "no media selected") even though it was playing an mp3 from the stick at the time....  I waited in case it was reindexing/syncing the disk but the problem persisted even after 5mins.   In addition, even though I have the haptic feedback on the track pad set to "force=0", the pad was shaking as my finger moved around.  A reboot of the infotainment (holding down the on/off switch for a few seconds) and the voice commands started working again, and the haptic feedback was off as expected.  Last week I was also experiencing some intermittent behaviour when changing the map view (cycling between north up, vehicle up, and the angled view) but have not seen these issues again. 

I have this logged with customer relations and the dealer but I wanted to see if anyone had come across these issues.  I wonder of these are software bugs (that everyone might see) or a hardware problem specific to my RX.    I don't want the dealer to rip out and change the infotainment system if this is a common software bug that needs fixing rather than a specific hardware fault.

 

So far, my total list of issues (after 2 weeks ownership) are:

1. car plays mp3s in alphabetical, rather than disc number/track number order  (work around by renaming mp3s as  "%disknumber.%tracknumber %title".

2. haptic feedback turning on when it is set to off (goes away on infotainment reboot)

3. cycling through different map views and returning to the angled/3D view, the car is not always pointing up on the map (goes away on infotainmemt on reboot)

4. Been trying for about 10 days to activate the wifi subscription.. still not managed... (many people seem to have issues with this)

5. Rattle in driver's door (steadily getting worse)

6. Intermittent behaviour in voice command system (goes away on infotainment reboot)

 

I'm booked in on Tuesday at the dealer...

Any ideas, folks?  After 8 very happy years with the brand to date, I'm feeling pretty unlucky at present.

Thanks,

Paul

Disappointing. Please let us know what the dealer comes back with.

Let us know how you get on.  I’ve got a new RX Takumi and, occasionally, I get a rattle in the drivers door.  I can’t put it down to particular outside or inside temperature and there’s nothing but a microfibre cloth in the door bin.  When it does occur it doesn’t stay on for too long - thankfully.

Hi All,

Just an update. A software patch was applied today that should have fixed the track pad issue of haptic feedback turning on when switched off in the settings.  Working so far.  It may have addressed some of the other issues too, but it possibly also created another one 😞 .  I'm now on a Feb 21 release.  Rather than bore you with my speculation here, I'll post back when I have more concrete info.  As you would expect(!) the rattle was not present when they test drove it.  That one may take a while to find....

Lexus also think they know why I cannot activate my WIFI subscription.  It seems my car was registered a couple of days before the free wifi offer ended, but I only picked up the car (and tried to setup the wifi) a couple of days after it ended.  It seems part of the Lexus/Orange backend may think I should have free wifi, and part of it thinks I need to pay.... and it's falling over with some conflict.

Cheers,

Paul

Hi All,

Thought I'd post an update and see if anyone else has been seeing these issues.  I'm now suffering from many many bugs in the infotainment.   The trackpad haptic feedback turning on when it was set to off has been fixed, I believe, but voice commands for playing music off the usb stick (play album XXXX) are now almost totally broken.  The exact same stick works perfectly, with voice commands, in my 2015 NX....  

Yesterday's bug was that when I select a radio station from the list of available DAB stations, the car plays a different station to the one selected.  This seems to be an "off by 2 error" in that what gets played is the station 2 entries up in the list from the one that I click on.

Have any other RX owners (with the newer touch screen infotainment) seen these issues?  I'm trying to help Lexus get to the bottom of this as fast as possible so gathering as much info as I can.

Many thanks,

Paul

Peter,

The rattle in my drivers door turned out to be the door bin itself.... not something in the door bin, but I assume the hinge mechanism where the bin extends.  It's fixed now I think.  Might give you a clue where to look/get the dealer to look for your rattle.

Looks like a lot of the issues you’ve described may just isolated and not general, to the 2020/2021 model. I have the same car RX Takumi picked up new las December and have none of those experiences other than initial wifi set up niggles. A Lexus technician eventually assisted me with the WiFi  set up and it has been perfect ever since. 
Not really sure what advice could be given, which dealership are you dealing with? As it may be worth approaching others especially with technology related issues . Hope you find a lasting solution to help you enjoy your car.

Hi All, thanks Banji for the reply.

Sorry for my long reply but some of this may be useful - particularly with what I have found in the Feb 21 software update to the multimedia system...

 

1. car plays mp3s in alphabetical, rather than disc number/track number order  (work around by renaming mp3s as  "%disknumber.%tracknumber %title".

This is acknowledged by Lexus.  Let's hope for a fix where the system reads mp3 track number id3 tags....  I can only encourage people who are annoyed by this to raise it with their dealer and with customer service.  I can't imagine this is more than 1 afternoon work for a programmer.

 

2. trackpad haptic feedback turning on when it is set to off (goes away on infotainment reboot)

This was acknowledged by Lexus and fixed in the Feb 2021 software update.  If you usually leave the trackpad haptic feedback on, you won't have noticed this of course.  I turn it off and hence noticed it.  Anyway, it's fixed in the February update.

 

3. cycling through different map views and returning to the angled/3D view, the car is not always pointing up on the map (goes away on infotainmemt on reboot)

I have not noticed this occurring again since the dealer updated me to the Feb 2021 software.

 

4. Been trying for about 10 days to activate the wifi subscription.. still not managed... (many people seem to have issues with this)

This is now resolved.... my vehicle had an additional problem where it was registered in the free-wifi trial period, but I picked it up a day after the trial ended, hence various things on lexus link were completed before and after the free wifi cut off.  This was a "special case" for my car and is now fixed - free wifi enabled for 6 months.  Required some back end work in the online system by Lexus.  Bad timing/luck on my part.

 

5. Rattle in driver's door (steadily getting worse)

This is fixed now I believe as of a trip to the dealer yesterday.  It seems the rattle was in the extendable drivers door bin mechanism.  I also had a rattle where the dashboard meets the a pillar just below the speaker.  This was also fixed yesterday.

 

6. Intermittent behaviour in voice command system (goes away on infotainment reboot)

This got much much worse since the Feb 2021 update was applied and now no longer works at all.  The voice commands do work for everything apart from "play album" etc for accessing memory stick music.  The same usb stick works totally fine in my 2015 NX, works fine in a 2015 IS, fine in a new UX and  does not work in a 2021 NX and another 2021 RX I have tried it in at the dealer.  It may well be that if you have not got the Feb 21 software update yet (which I got because it fixed the track pad issue), you may not have seen this issue with voice command music playback.  Banji - do you ever use voice commands for playing music off a usb stick?  If so, be cautious about being updated to the Feb 21 software at your next service...  This issue is not totally confirmed yet, and I will post an update as soon as I have more concrete information.

 

Thanks everyone for reafing and I hope this is useful.  The main word of caution is that the Feb 21 update seems to have totally broken the usb music voice commands.... at least for me.  Lexus are investigating.  We still have to totally rule out the issue being my music/stick, but the fact that it works on my wife's 2015 NX, and the problem has gone from intermittent to always on the RX since the Feb 21 update was installed, suggests to me something has happened recently in the code base to break this.

Thanks,

Paul

hello

just a thought. Have you trained the voice recognition by going through the tutorial on the screen? This significantly improves voice command system performance.

Hi Jason,

Thanks for noting this - however I think the voice training has been removed in the later versions of the head unit software.  I seem to remember we had this on our CT, but it's not on the new RX (just checked the manual and can't see any mention of it.  Interestingly I think it is still present on the American systems...

Problem for me seems to be that the voice command system is not even indexing the album/track/artist names on the usb disk.
