When I put in the destination in the nav on my 2023 RX350H and there is traffic it used to show red, dark red, or yellow or blue on the route we were on depending on the traffic flow.
Now it continually shows blue no matter what the traffic is.. I have the same issue with out 2022 NX 350. Is this a cloud issue?

 

Does it show red in traffic with no destination set? If not, seems it's not receiving live traffic data.

 

No. Just shows solid blue

 

I have noticed the same problem with my 2023 Rx350. Also when using navigation the lexus system does not give verbal warnings like my 2019 Rx350 did. For example, “traffic is stopped 20 miles ahead”. I miss the warnings. Most of the good things the old navigation system did have been eliminated in the 2023. Too numerous to mention here but are covered in other threads.

 

this issue it seems is related to the flaw in the dcm module . i t is the same module that keeps dropping the integrated amazon or apple net work connection making it unusable.

supposedly there is a replacement module that came out in july 2024

 

How do we access the replacement module?

 

good question…i turned the info i had to my dealer and they are not getting much help from lexus .

the info was originally posted by a poster here

The Digital Cloud Control Module has an engineering design flaw as Lexus Japan electronics design engineers uncovered. Lexus used my car to debug Apple Music network error. After 12 months and many escalations, Lexus debugged issue and redesign a fixed cloud control module. I was told my car was first in America and Canada to get this new part that includes cell antenna. Sure enough, all the connectivity now works. Since nearly all owners use car play (using phones cell) instead of Lexus music lovers package, the issues were rarely noticed. I’m told all rx500h up to early July 2024 have this defect (unless getting the redesigned module). The defect also can impact speed of profile loading, software updates can freeze part way or take multiple attempts (unless on WiFi), and Navigation often would not update every 15 minutes as advertised such as not showing closed roads. Voice control might have been degraded too but Lexus just rolled out a software update that may minimize some of the original cloud control module’s defective functionality. To test your car, you can sign up for $15/mo music lovers package as well as needing Apple Music or Amazon music. Under profile settings, make sure to deselect car play and enable media. The network error was seen on multiple cars at my dealer (till new module). To prove hardware design defect, Japan Lexus engineers sent my Lexus dealer a laptop with cable/ connector for an engineering debug port in that module and walked the service people through the debug till the Lexus engineer in Japan said he is 100% sure of the cloud control module has a design flaw that was cause of network error that shows on cars display and disconnects integrated music. As said before, the newly designed cloud control module allows robust integrated music, navigation, software updates, and loading of profiles.



“I responded to this topic in earlier posts plus on the clublexus forum. Every rx500h made before August 2024 has a cloud control module (also called DCM) that has a major design defect. I worked with Lexus for 1.3 years to solve the problem. The original Lexus engineers from Japan redesigned the DCM hardware and installed it in my car so Get your DCM replaced with July 2024 DCM. The problem as explained in club Lexus is that Lexus dealers other than mine do not know of this. Lexus decided not to list a new part number which a Lexus employee told me was to prevent needing a recall. They know 98% use CarPlay and cell phone network so don’t want everyone to know about this. You should have your dealer call my dealer who worked with Japan engineers to find defect and show it effects all original DCM. Have your Lexus dealer Contact Adam the service manager in Lexus of northboro MA

 

Bizarre, why would the RX500H have a different cloud module than other RX models, or any current Lexus model for that matter?

Am I understanding this correctly in that it only affects the 500H and it has its own unique DCM? I could see different software, but different hardware as well seems suspect.

 

the head unit in the 2023 is the first to try to incorporate integrated music via a subscription to cell service

 

According to Lexus web site, the offering started with select 2022 models which actually came out in 2021. So I guess they busted something for the new RX.

But I agree most would not bother to use as Spotify, CarPlay, etc. would be much more desirable.

Why would anyone even use the OE navi when Waze/Apple/Google are all a millions times better?

 

we had a lot of trouble getting waze to work in areas with poor cell coverage …the built in nav uses both cell and satellite.

there are two benefits to using the built in music , it sounds better then car play and every time i use my phone and try to charge it i end up leaving it in the car and forgetting it

 

You can save the maps for offline use in Google maps.

Are you sure that the onboard Navigation uses Cell AND Satellite to get map and traffic data?

 

that’s what i was told

 

Over the years, Lexus has been progressively expanding the use of the Cloud to get more current and real-time information to the driver. Obviously, there are a lot of potential benefits here…UNFORTUNATELY, LEXUS HAS TAKEN ADVANTAGE OF THIS SITUATION TO REMOVE EXISTING CAPABILITIES. If a customer wants these new capabilities, and the associated “baggage”, wonderful. The problem is that they’re effectively forcing their decision on all their customers.

Perhaps the best example is the navigation system where they’ve decided to get ALL map and POI data from the cloud. Again, fine if people want it, but Lexus deliberately decided to remove local map POI database at the same time, forcing everyone into a subscription.

Some of us were content with a map database that was somewhat dated, and, if we wanted an update, we’d pay the $250 or so for the optional update. UNFORTUNATELY, their decision to not only offer the latest data, for a monthly fee, but to ALSO remove the ability of those who didn’t want the monthly fee to opt out. For those people who didn’t want the fee, they lose the whole map capability, even basic map capability. My 2013 GS navigation system worked just fine when I traded it in, 12 years later. For customers like me, imagine finding that we have actually LOST CAPABILITY by trading up!!

I will also point out that once you buy a GPS system, there is ZERO cost to keep using it. You can buy a handheld GPS that will be working 10 or 20 years in the future, and there are no costs beyond the $60 purchase price.

There are a lot of new capabilities which require paid subscriptions. The undisclosed, though obvious, reason a paid subscription is required is that Lexus decided to eliminate the local storage of map data. It’s obvious that Lexus decided to essentially make their subscriptions mandatory, to get most of the car's driver support functionality to work…greedy and dishonest.

But now just to add an extra push to the customer, they came up with the master data sharing agreement, and requiring acceptance. Sure, you could decline, but then they tell you that if you do decline, you will lose many capabilities, including those you may have paid for! Talk about outrageous!! Not surprisingly, they can’t give you a list of functions that you would lose - I asked. If they can’t give a list to current owners, why would they give a list to a prospective buyer? Maybe because the list of things you lose is greater than what’s left! If I had seen the list before buying, I would not likely be a Lexus customer.

And since we’re already outraged, let’s look a little deeper. What data would be shared? with whom? Actually reading through it reveals loopholes big enough to drive a truck through! All it gives you general ideas of how it may be used, but there are NO commitments of protection of your data from being shared.

How about just saying that the data will be used only where it is technically necessary to provide the services being purchased by the owner, and not released to any third parties, for any other reasons. Nobody should have any problem committing to that, unless, of course, they plan to do something with that data that an owner would object to. I think most drivers would NOT approve of their data being sold to data brokers or insurance companies,or released to law enforcement without a legal obligation to do so.

THIS IS JUST THE TIP OF THE ICEBERG! They are progressively transforming our cars into a fleet of privately funded vehicles, controlled by a centralized system, not accountable to an owner. Don’t be surprised if you walk out to your car one day and find that it won’t start, because it got onto some list you never even heard of!

If somebody wants to control my car, they can start by making the car payment!!
