When I got in my truck after New Year’s, it actually had the correct date of 2026 January 1. Is that other people are seeing? I tried moving and head by one day thing that might affect it but it didn’t.

I got the same thing today, except 1968 days as I clicked over 32,700km.
Looks like it is only affecting AU firmware so far.
Let's have a competition on who gets the highest number.

Steve B, baders and Jean Mercier no alert.
INEOS has acknowledged the issue here.
The numbers seem very random. The only thing I can see, is the date is before each car was even made - over 5 years ago. EDIT: every number is 4 digits and all are above 1800.
I'm still laughing my ass off at your reply. It is so on point for SJ, and hilarious visualizing him throwing a Grenadier at somebody.He'd demean someone on stage and throw a Grenadier at them. It would ironically the lowest point and highest point of that person career and life.
No hurry the guys have almost a year before they are at it againNearly 500 posts on this thread!
Come on guys., you can do it!
Maybe push towards 1000?
I’m really enjoying reading your analysis of the issue, although I prefer the original phrase “champing at the bit” over your modern corruption “chomping at the bit”. And are we taking bits or bytes?I suspect that changing the date manually in the console to be the real date today, and turning off the vehicle, locking the doors, waiting some time, I don't think that will fix this issue, but it's worth trying. You did this and it didn't fix the issue.
I'm confident that this is based on data that is on board, in the ECU most likely. The date/time might be fed in from outside, via the GPS unit perhaps. The center console is a separate unit, and there are other computers in the vehicle, they all get information from and send data to the ECU over the CANbus, a vehicle 'ethernet' network if you like. Think about how Teslas are updated over the internet, but for this vehicle, you have to visit a dealer to get updates to software, to reset things, or you yourself have to plug in a USB drive to the car for it to see an update and then load it when you tell it to. So it is very unlikely that there is any data or comms happening between the vehicle and the 'cloud' or back to INEOS, the only input from outside in a network sense is coming as input-only from the GPS sensor, no data is going out from the Grenadier over the airwaves or internet. Well, unless you have a tracker planted in your car.
It is possible that an erroneous input from GPS that fed a date in 2032 to vehicle systems caused this, and that GPS now giving correct dates can't undo it.
Things in an ECU and other computing components in a vehicle are simpler than you'd see on a PC or Mac or even a mobile phone, space is limited, memory is limited, I've seen this in software written for space vehicles -- a lot of constraints.
To determine if service is due, there is either a computation done within the ECU that compares the last service reset or date, with today's date, or there is a simple memory location that acts as a counter, and increments by 1 each day, and that another part of the code reads and an 'if' statement that says: "if COUNTER is > 365, tell console to display COUNTER - 365 days overdue for service". Could be other ways to do this.
I'm betting on the latter, as date adding and subtracting is tricky, and a counter that can be reset to 0 and count up by 1 daily is much, much simpler for the purpose of determining how many days since your vehicle service has been done (and service counter reset).
The days overdue for service increments at 1800 Eastern time, which is UTC+1 midnight time (most of the EU, incl. France), and the ECU I think updates the counter by 1 at that time. It's possible that the ECU will take the new date at that time and calculate the difference between it and the service reset date, and increment the service counter by that many days, but that seems unlikely as it's more complication than needed to do this function. Still, maybe there are vehicles that they expect may be de-powered for long periods, maybe in shipping, and they coded it to take the date from GPS and do those calculations.
Having said that, this is all speculation based on experience with embedded systems, but not any knowledge or experience with the internals of the Grenadier's systems. I am chomping at the bit to get access to the embedded systems architecture and software, I'd even sign an NDA if necessary, to understand what happened in this case and help improve these systems. The Grenadier platform is brilliant, and I think it should be stuck with mostly, with changes coming as fixes, improvements, iterating evolution, not start over or make huge changes like you see with between the 5th and 6th gen 4Runners, but you didn't see between 4th and 5th gen.
My best guess is that 5 year's worth of days was added to the internal ECU time and it incremented the service counter by that many days. Could have been that a date in 2032 was provided to the ECU, could be that something jumped that Service counter by that many days, no idea.
Whether changing the date manually in the console and having the ECU pick up on that and then adjust the service counter, I don't know -- I hope so, would then be easy to fix this.
I trust IA engineers are working this, and we'll hear relatively soon what happened and what to do about it.
I wonder how bound IA is to proprietary hardware and software that is limiting and constraining what they can do. Engine management and other systems, would be nice to have open source alternatives.

To calculate the actual date the next service is due, don’t we first need to determine the date of our previous reset (using your column 3 and going back that many days) and then add 12 months to that?Using that premise, here is @TheDocAUS latest list updated to show a corrected due for service date. The column "daysToServiceDue" is calculated by subtracting 5 * 365 = 1825 from the "daysOverdue" value.

If the maximum service interval is 365 days, for anyone with a "daysToServiceDue" of 365 or greater, the data doesn't make sense since this implies that Emil had his service reminder set on Jan 1, 2026 and that the users after him are granted more than a 365 day service interval. So something else is likely going on there.
Can the dealer set a service interval greater than 365 days? Maybe + 3 years like @Krabby suggests or + 12 years for @rwhitinger? I think we all want that 12 year interval!
. . .Found this comment on the Reddit Grenadier forum.
I started the vehicle and found my (automatically set) clock showed the correct date. I set it to manual and wrote date data for year = 2027, then wrote it again with the current correct date (I assume it was written since I backed out of the menu each time). I locked the doors, waited 90 minutes, the unlocked the doors and started the vehicle. The service overdue message was displayed with the same expected value. I set the date / time back to auto and the error message was still displayed."We think we resolved the service overdue warning in another thread about it, but here’s how to fix it - go into settings, manually set the date to 2026, not 2032, turn off and lock the doors, come back a half hour later and the service message is resolved.
It's only corruption if I know it is and I intended it. I thought it was chomping. But we have a new rescue dog with some Frank Sinatra teeth, so maybe I'm channeling him? My mother is a Brit BTW, and we lived in DE and the UK for 9 years total so I should know better. But look at those teeth!I’m really enjoying reading your analysis of the issue, although I prefer the original phrase “champing at the bit” over your modern corruption “chomping at the bit”.

The 2054d mine displays is 5 years of days plus the distance from 21 May 2025 to today. I was 140 or 141 days past my last reset, plus the 5 years of days (incl leap days) that were inadvertently added on 1 Jan 2026.To calculate the actual date the next service is due, don’t we first need to determine the date of our previous reset (using your column 3 and going back that many days) and then add 12 months to that?
In my case, with a displayed number of 1889 days, my last service was 64 days ago* (October 29, 2025) so my next service is actually due on October 29 this year (not March 6 this year as your column 4 suggests) or am I missing something?
* I realise that some of these numbers change each day, but my last service was indeed on October 29.
I would argue that corruption, both in terms of linguistics and data, can be accidental, but out of a strong desire for self-preservation, I won’t argue with your dog.It's only corruption if I know it is and I intended it.

But doesn’t your table show me as due on March 6 ?It may be off by a day or three, because the ECU is on UTC+1 time, so my calculation is back by at least a day for your time zone. I have you at 2 November for service.

I haven't posted any tables. I think that's someone else. I wrote a Tcl script that takes the date you read your days of service overdue, and the number of days overdue, and calculates your last service reset date in Eastern time zone.But doesn’t your table show me as due on March 6 ?
My mistake. The table I was looking at (on page 25) was posted by @Glen in response to one of your posts. I’ll get him to check it. All the best to you (and your dog).I haven't posted any tables.

I tried the above method with the engine on confirm to be not working. I'll try now with the engine off.Found this comment on the Reddit Grenadier forum. I don't know if it works, I just tried it (though without engine running, just key set to accessory mode) and will check on it later or tomorrow. If it doesn't work with engine off , I'll give it a try with the engine running next time I'm out and about.
Do post here if this works for you:

I don't know, members complaining because they haven't got a fault. We seemed to have turned the out come of the forum upside downMy build number is 9848, and I still have no service reminder, so I still feel like I am missing out.
What is your build number Jean, I know it is a lot earlier than mine, and if I remember yours is petrol, mine is diesel, you are in Belgium I am in Australia, or are we just special, or has Ineos forgot that we exist.
