Are they really this bad? (Software, electrical gremlins...)

First Post here. I want to buy a Grenadier and have been doing my research for several weeks now, but am getting put off by all the references to software glitches, electrical gremlins and so on. For example, the screen grabs below are from less than 5 minutes browsing a couple of Grenadier Facebook Groups yesterday. This does not instill confidence.

I'm keen to hear real-life owner reports.... do IG's suffer from software and electrical issues like this much?

And are the petrol versions any more reliable than the diesels? I would imagine that since petrols have no DPF, AdBlue and all that junk then maybe they are... but many of the electrical/software issues don't seem to relate to the engine but the car in general.

Those glitches and quirks and problems are from real owners... Do they suffer from software issues Yes without a doubt. Electrical only issue I know of is when you are doing a brake controller addon. The B58 is the best platform for any similar option on the market. Hence why Toyota even uses it. Honestly the only issue that would keep me from being a repeat buyer would be the Front Driveshaft issue.
 
These responses are both true:

1. Online forums bring out problem reports. For every person posting something positive, ten people are griping. It's the nature of online and rarely offers a balanced perspective.

2. If those problem reports put you off, then you might be considering the wrong vehicle, as this is a brand new model from a brand new manufacturer. Buy the second model model year of an existing vehicle from an established manufacturer.

The are problems, but the vehicle is incredibly well-built. It is a fantastic daily driver for me. Ineos is figuring it out as they go, and ownership will require some patience.
 
My early model had the door seals and locks replaced. The only other issue being a cheap plastic connector on the diesel EGR. These were replaced on an Ineos campaign for a redesigned version.
No software glitches, heater works, no problems with the driveshafts.
 
For me, the worst part is the trucks handling. I never really had too much of a problem with software. Granted there were some issues and mine is certainly not perfect. But the handling and front shaft issues are real. The handling issues can be adapted to or largely corrected. The drive shaft issue has yet to be solved. Though I am cautiously optimistic that it will be handled in the coming weeks or months.

This truck is not special and shouldn't be held to any different standards. People here and there will tell you it's some hard core old school military grade machine that is just going to handle as it does. But being a collector of hard core, old school military machines both vastly bigger and even smaller than the Grenadier I can say non drive as shit as the Grenadier when it comes to steering etc. But at least the Grenadier is more comfortable 🤷🏻

Go look on any forum. Jeeps are earring camshaft’s, Toyotas GMs are blowing engines. Fords have cam phasers going bad. Forums have a self selection bias.

I have 22,000 miles on mine. It’s been good. Had the HVAC issue fixed but that isn’t an issue with the newer builds
