My 2022 580 EQS has been in the shop for 2 days plus a 3 day Labor Day holiday. Is anyone else experiencing prolonged service time for the most recent software upgrades prompted by their recall notices? Is it incompetence, poor software or Mercedes server issues? So far I am impressed with the engineering of the car but MB needs to hire better software engineers.

Mine had that recall update recently, and the 20K service. Seems the dealer had no filters in stock and they had to be ordered. At least, that was the story. But, it was in the shop for three days. They did give me a very nice EQE SUV loaner. I was surprised that the service took so long.

I did the second of my EQS 450 recalls last week. It took about three hours. I had taken a ride back home or I might have gotten it done a bit earlier. The first recall in July?? I left it there and told them to call me when done and I was in no hurry. Took two days mostly I believe because I used the words 'I"m in no hurry'. Dumb as a rock thing to say at a dealership.

Had my EQS 580 in last week Monday for three recall updates and the MBUX update to 330. Also went in for the 20K service. It took a day and a half and the 20k service wasn't performed for the same above reason (filters and wipers are back ordered)

The technician said he had trouble with the connection with the servers and that the download quit three times before he could get them installed.

For what it is worth, the sevice manager said that one software update took 9 hours. Just be prepared when you bring your vehicle in for the update. Hopefully OTA updates are in the near future.

BMW does OTA updates. I don't know why Mercedes cannot ? I don't want to deal with dealers if I was an owner for OTA.

Hey in winter months how much range degradation is there in EQS SUV.

LAZARU5

Not sure how your question applies to klondike616's post. But, my experience after driving last Winter is that you should expect a 15% to 30% drop in the estimated range compared to the Summer months.

Has it been confirmed that EQS cars don't do OTA updates? By default, the car isn't connected to an internet WiFi that downloads the updates. Perhaps that's why people aren't getting OTA updates?

The car actually has two WiFi connection settings - one for internet and one for updates. I literally have my car connected to two separate WiFi networks, the 5GHz for internet and 2.4GHz for software updates. The settings don't allow for the da same network to be used for both purposes, which is really odd.

I personally like BMWs software architecture. Each I-Step release is a full vehicle integration, such that every ECU that is upgraded is vetted to work well with the others. Essentially, the vehicle is brought to the newest software standard every time a ECU needs to be programmed. My MY2017 3-series is running 2022 software. There are three I-Step releases each year, for each platform. March, July, and November. Dealers get the latest, while OTAs lag one cycle behind. On Mercedes, they upgrade each ECU individually such that one ECU can be up to date, but the rest lag behind.

I received one OTA update several weeks ago for the sound system, but agree MB isnt utilizing the full potential of this feature like Tesla is. My guess is superstition, hesitancy, or complete lack of confidence in the delivery channels.

There is supposed to be a massive software update for the EQS as part of a large 2-wave campaign. I'm eagerly awaiting my turn...and my complimentary pillows.

Was expecting a couple of hours, but 9?? Do they just park the vehicle somewhere and let it do its thing or does it have to occupy a service bay space? Either the update is astronomically big or the dealership have dial up network or for some reason it takes forever for the car to install the update, or a combination of all.

Based on times mentioned I assume they are signing the packages specific to the vehicle but even then they could technically prepare those ahead of the time when service is requested so it just becomes a download and install.

I have not been impressed with MB and OTA updates. In all the years I have owned a Mercedes Benz vehicle (7 cars), a recent OTA update to my 23 EQS 580 sedan was the first one I have received. And this was for the defroster to work better so the safety cameras would work better. Unless you are having a specific problem Mercedes believes you don’t need to be updated. Hell, can you imagine the outcry if Apple waited till you got hacked before they would let you update your phone. In fact I just updated my iPhone today because of a security patch. I’m reading on this forum that so and so had to take their car in for this update and that update instead of sending out an OTA for everyone. Yes, I understand that some updates require a visit to the dealer but I can’t believe lots more couldn’t be done OTA. And why do we have to have a problem before they will update the MBUX version? I would hope they fixed something or added something in an updated version, so why can’t everyone get the update? I guess they figure that’s all the service centers would be doing if they offered it to everyone.

For the most part, MB OTA updates are limited to the Infotainment system and the HERMES communication module. They've recently pushed out an update to prepare the cars to receive OTA updates for other modules. The difficulty is in the way the Germans build cars. Every ECU is pretty much outsourced to other suppliers, so there is no common software stack and architecture that would allow for OTA updates. Not sure how BMW does it, but Tesla has written their own OS for their cars and there are only a few ECUs in a Tesla, so they can easily update every software aspect of the car. A typical Mercedes can have over 100 ECUs and each one was outsourced. They don't run a common OS or development environment and the individual updates have to be signed off by the supplier. MB can't just push out updates, because they often don't even own the rights to the software.

The problem with Tesla's architecture is that if the main computer crashes most everything stops working. The distributed architecture of German cars adds redundancy. If one ECU crashes, most other functions continue to work. Each approach has its advantages and disadvantages.

As for the time it takes to update these ECUs there's another factor, the CAN bus. There are different CAN buses in a car. There are high speed and low speed buses. So the update has to be delivered over the CAN bus to the respective ECU. If it can be sent over a high speed bus then the update is quick, but over a low speed bus it's slow, but even a high speed CAN bus only has about 1 Mbps bandwidth.

Hmmm, ya would make more sense they do that in the backend instead of having to do it in real time because an update taking this long really holds up all the service bays when there might be actual mechanical issues with other vehicles but can't get fixed as a result.

Could you please elaborate on your post? I wasn't aware of 2 Wi-Fi connections.

I can only speak for MBUX on the Hyperscreen. Under the Software Updates settings, there's a setting called "WiFi Hotspot for Updates".

I had the same issue, My car stay in the dealer for 1 week because they told me, "Your car lock while doing the update and we are not sure what to do".

Wave 2 of the 2023070020 software update went live today in the US. Covers about 12,445 cars and a separate campaign was rolled out to install the rear lumbar pillows.

How do we know if our car is part of this? Would they show up on Mercedes recall website lookup?

W205C43PFL

It will show as OPEN in the VMI (vehicle master inquiry).

sarhoshamiral

Meaning I have to call the dealer?

W205C43PFL

That is the easiest route... if MBUSA recall checking site (which you mentioned) shows nothing when you enter the VIN.

This is just anecdotal....was visiting my son in DFW this weekend. I was waiting in his King Ranch F150 while he was in to pick up food, and got a flash message on the display stating a software update would be installed at 2:00 AM that night, and the truck would be available to drive again b y 2:30 AM. There was an option to delay installation if necessary. Pretty nice.....wish my EQS did that!

capt_slow

Data point on this. The MBUSA recall site shows zero campaigns active for my VIN. However, dealer confirmed both the software update and pillow campaigns are active in VMI for my car.
