The obvious upsetting part about this, is, you cannot document your own changes as advertised, and have it count. As such, the catastrophic failure at this mileage, which really cannot happen to any diff sold by anyone, anywhere, other than with a manufacturing issue, isn't being covered if you happen to live remote, which was the whole purpose of the truck.
I try to avoid labeling people with the fanboy tag, but think about this fellas. This guy is not to blame, and the dealer and Ineos knows it. If the diff fluid wasn't changed at 12000, and this used cast gears that needed it, the absolute WORST outlier one should expect at this mileage is pre mature wear and noise. Being that changing consumables (oil, belts, hoses, etc) are set at intervals that statistically guarantee (ideally) NO failures under warranty, even THAT becomes a wild ass stretch to say its due to consumer neglect and therefore shouldn't be covered. This is a horrid outcome and everyone should be on notice. You know what happens to GM ls engines that don't have the oil changed and fail? They swap it. Ford? They require receipts, then they rebuild it. Ford f350 diffs are 30,000 recommended if working at max load. 150k if just a mall cruiser. But if the warranty is active, it's just covered period. I've had guys do stupid shit and ignore service with assigned company trucks, but I have NEVER had a warranty denial in all these years. Blaming this fella for a catastrophic Axle assembly failure at 17000 miles is utterly indefensible bullshit for a manufacturer, and portends deeper issues. He had it in at 75% of the mileage, and if it was THAT critical, he SHOULD have been told to have it done. EVERY time I've had service interval done the manager tried to up sell to the next one just in case. It's what they get paid to do.
All that, and if axle failure is a possibility at 17k without the fluid swap, why the hell did they use these in the first place?
