With exception of the 1st (ac) issue, the remaining symptoms provided point to a case of PEBCAK.
Steering is what it is. It's not broken.
Instead, it would appear it is the driver that needs to become familiar with their vehicle and it's intended purpose. If one spent more than 1/4 Mi down a rutted, rock-riddled, off camber road the IG's choice of steering becomes VERY apparent. The Toy (or nearly any IFS) steering would be trashing back and forth. (Keep those thumbs UP and OUT!)
On the Road, the Gren is "slow" however comparatively to the "competition", when Off Road, they fail in comparison to the Grenny's.
The 'issue' with the Roof rack, again is lack of understanding and just making an 'assumption'.
Failure to properly brush off snow from a vehicle prior to departing, again points to Operator Error.
The "chime' for overspeed can easily be disabled, in far, far fewer clicks than took to log in to the forums and vent. It is literally 2 button presses.
