New Year Service Overdue Bug

Until the 2027 model year, we should have the option to turn off the annoying nanny. Just like we should have the option to turn off all the other annoying nannies.

You know what's dangerous and distracting? A car that is constantly flashing lights and sending messages across it's screens. Each one causing you to divert your eyes from the road for a moment. I wonder how many accidents are caused by the distractions of the very devices that are supposed to make us safer? It's a valid question. Pretty soon it's going to flash us a warning then warn us that we're distracted.

It's also a cost consideration. All these federal requirements "to make cars safer" (technology for the sake of tech? Lining the pockets of parts suppliers?) do indeed come at a cost. Our cars are more expensive and complex. The average new car runs close to 10x more lines of code than a Boeing 787 Dreamliner. Seriously, some cars run 100 million lines of code. Cars are so complex and parts intensive now that about 25% of them are written off as a total loss by the insurance companies (in the US) after a crash.
It increases the costs of repair. Everything need to be calibrated.
 
I think it's a timer. Once a week I've been making a trip up the hill to ski. It comes on at around the same place on the trip up, and then around the same place on the trip back. Seems to come on around 2 hours or 120 miles-ish. I can't think of any other reason. Also, since I've had my vehicle serviced since the new year- it is an option that must be disabled EVERY TIME I start the car. Stupid.

And by the way, a 3 hour drive is peanuts. I like to get that in before breakfast. Something like 9 hours would be more accurate for the western U.S.
I don't have to turn mine off, I think I've left it on and get no errors or lights or bongs. I'll have to check later.
 
Was back at dealership for other warranty work & saw this on my receipt when I picked it up. Didn’t ask about it this morning as I didn’t think there was a fix yet.

I sent four "service overdue" bug questions to Ineos Customer Service. I made it to the second tier, but half of the final answers were underwhelming.

I asked one question explicitly to both Ineos and my dealer -
"1) Has a software update to correct the initial defect been released to Ineos dealers in the United States?"

On 19 March, Ineos emailed -
"Yes, there is an update available, and all dealers have been begun performing repairs."

I forwarded that immediately to my US dealer and also on 19 March, he emailed -
"We have not received the update to fix the service warning at this time. All we have been told is that they are actively working on a fix."

This left hand/right hand thing is not new. I have to trust my dealer's answer; I cannot drive 700 miles based on anything Ineos says.

On a brighter note, I asked -
"4) Is the solution (software update) consistent across all North American Grenadier variants (24.1, 24.2, 24.3, 25.1, 25.2 and beyond)?"
Ineos says -"Yes, there is only one solution for all affected vehicles."

Good luck everybody. At this point, I'm just hangin' out 'til 1 Jan '27.

EDIT/UPDATE - I'll share another question/answer based on the receipt image above. Did @ScotsmanSD get the real software update fix? Sounds like it based on similarity to the answer below. My dealer could be wrong. I don't know what to believe. I'll keep checking with my dealer.

"3) In the context of the New Year's service overdue bug, can you please explain what a typical service reset will accomplish versus a software update to correct the initial defect?"

Ineos says - "Simply stated, the vehicle doesn’t understand what year it is. The update will correct the issue with the date/year and keep the correct service interval intact, so the vehicle continues to be maintained properly."

I've posted this link to a bulletin on the NHTSA website previously.

This is the action to address the current display error. There is also a note about a pending software update to correct the root cause.
Dealers should be able to apply the custom calculation fix now to make the service message go away. The corrective software update can follow up later.
