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."
