How about this then. I have, in recent times, owned a Suzuki and a Honda. I still have the Honda. The Suzuki had issues, including a factory cam chain tensioner that was a bad design. It would wear out the cam chain early. There was no factory fix for it and the solution was to know about the bad design and replace it with a good design tensioner. My Honda has a recall for a bad relay. And the Honda has incredibly poor quality parts. So I am batting 0 for two with the Japanese brands.
You had a dealer miss a bolt. Some of your other issues, well some of that is clearly the bike. But did you expect a Guzzi to run like an appliance? If you did you clearly did not do your research in advance of the purchase. Guzzi's tend to come needing a little work to finish what the factory started. Once that work is done they tend to last a long time and are usually very reliable. Not everyone is meant to own a Guzzi as they do need that extra effort from the owner. But Guzzi's are clearly not alone in having problems.
I have four Guzzi's and would have no issues riding any of them across the country, other than getting the required time off.....
I'm 66 years old and have owned motorcycles since I was 14, more than I can count or remember. I have 4 in the garage right now, representing 3 different countries of origin. Aside from 2 lovely Brit bikes in the 70's with electrics by the Prince of Darkness and oil seals made of cottage cheese, not a one I've owned has been as, umm, un-appliance-like as the V7S. I'm fully aware that motorcycles are neither sewing machines nor washing machines nor cars nor passenger planes. But anything built in 2014 and costing what this did should display better quality than this does. And yes, of course I did a lot of reading and research before I bought it. The Guzzi fan-boys that buy these things all say pretty much the same thing - wonderfully reliable pieces of fine European craftsmanship that last a lifetime, albeit with a few 'rough edges'. In my mind, there's really no excuse for either the poor manufacturing QA, or the cavalier attitude of seemingly most of the dealers, including the supposedly reputable ones.
"Ahh, whatcha gonna do, it's Italian, must've been too much vino the night before, ha ha ha". As I said, this is now pretty much my around-town bike, and when I get tired of that I'll pass it along to someone who appreciates spending endless hours wrenching on it or watching it leave on a flatbed for yet another trip to the dealer.
