Quartermaster Failed Driveshaft - Be Aware

I just wonder why the INEOS Engineers didnt pickup on this in their million miles of tests and what not...

Depends on the actual variety of the test miles. Like a private pilot who flys the same hour a 1000 times around his home airport versus another pilot who flys 1000 hours going to different places facing more challenging conditions. You tend to learn more in the process and find your weakness and improve.

But yeah, you’d assume IA would really put these things through there paces and individual test mule vehicles with miles on them would show some of the common pattern failures owners have reported on this forum.

I know some had a real beating in the southern African testing as i have met people who were involved, so curious as to why it didn’t happen then

I suspect the test flet wasn't big enough and they didn't torture the cars enough.
To give you an idea, when I worked in autonomous driving we did 1-2 million miles autonomous test drives a year with a tiny fleet. Total miles on cars where 4 million miles a year. Ineos in their launch report stated that they did 1.1 million miles total which to me sounded way too limited.

My company did 2 million miles in simulator a day for several years and a few hundred thousand scenario tests a day. We had a couple of steering columns and brake columns on bench tests at a few thousand of mechanical tests a day. On the vehicle dynamics side we did both full scale simulation with full physics models as well as on track and skid plate extreme scenarios while having sensors everywhere to check for approaching limits. Everything goes to databases for long term analysis. Roughly 1pb of data a year per vehicle worth of sensor data that we mined with advanced algorithms to detect wear and fault patterns.

The 1.1 million miles worried me at the time. I got more comfort when the Aussies and British became beta users and I got in post that cycle with limited infant mortality type of faults. So now is mostly wear issues as far as I can tell.

I think this is a wear issue that more extensive testing would have found but it is what it is for me -I've done the plunge and am now committed.

Or did it and they made adjustments and assumed that was the fix............hmmmm ?

Happy to have been a tester for you

Shame Swampy hasnt been back to give an update on the situation.

Or maybe they focused too much on low speed intermittent abuse off-road and such and neglected having multiple units just for high speed road miles. Because I doubt anyone that uses these as a ranch truck or an estate vehicle (as I understand them) will ever have issue.

Well there is all that but many of those in the know seem to have visually just looked at it and declared the pinion angles or whatever are too extreme for extended durability/reliability.
Shouldn't engineers know this?
