it's unfortunate that an assembly line forgot to check the torque on those bolts. It's also unfortunate if you choose to ignore it and they come out, it basically destroys the entire HST assembly, rendering the tractor useless, well, unless you want to use it to run a stationary generator or pto pump (where the tractor just never moves).
Lemon laws (at least here) only apply to motor vehicles. Tractors are not considered motor vehicles, thus they are exempt. Every state is different so check yours.
Years back there was a recall on the smaller standard L series had to do with the pto over-run "clutch" assembly. Weren't a lot of them, but kubota sent factory techs (ours were japanese) to do them on-site, at our dealer. They did 4 one day, 4 the next and 3 on the last day they were there. Of course we're talking about a much less involved job and they had 5 guys working on one tractor, so they had them split, fixed, and reassembled in no time. The way the Grand L & MX HST recall works is that they pay a certain amount of labor and then parts (plus any incentives that might be applicable) to do it. Normally that's one tech that does the job, sometimes he's gotta get help from a second. I'm out of town and looked at another kubota shop (here) and they really aren't set up to do them, yet. THey've got to order some jacks, splitting stand equipment, hoist, and a few other things, and all that stuff is on hold due to Corona (like everything else) so they're stuck. They're probably going to miss out on a substantial incentive because of the amount of time that it takes to get all the stuff they need.
Sadly, this is a part of dealer work. No matter how well equipped your shop is, it seems like you never have the tool you need, and the boss ain't gonna buy it because it's a one or two time a year use, and sits the rest of the time, that and it costs money. Some of these tools are really expensive (tens of thousands). The place I worked for had $762,000 worth of special tools alone, not counting each tech's regular tools, in my case $23,700 worth (and that's a lot of harbor freight stuff, mix and match-not a lot of name brand). So as you can see there's a lot of challenges facing the techs, dealers, and KTC right now, and it's not getting any better. A big challenge for the local (to me) dealer is that they have had record months from March until present, and they're not really set up for the amount of business they've been seeing. I mean that's great and all, but it also means that there are backlogs, delays, and backorders. If you combine it all together, it can sometimes turn into a big mess.
It is exactly the same way in automotive dealers. Been there, done that. THe difference is that with cars, they are more or less essential meaning that there is a distribution center on every corner and a part is available almost immediately. Secondly car dealers pay their techs a LOT better (WAY better!!) in most cases--and the better paid techs are the ones who take the most pride in their work. Tractor shop? $12.00/hr and that's the kind of work that a $12.00/hr tech turns out, cheap, fast but not good (usually). There are exceptions. And car dealers have a much higher margin, so what they are getting for a new car is a whole lot more than what they paid, where in the tractor business, 10-12% is average, and frankly isn't enough to pay all the bills that their customer base expects them to have. They're expecting a 100,000 sq-ft facility with 25 of each of a full line in stock at all times, and to be able to get service RFN, and parts immediately. It just ain't happening like the car/truck industry is. It should be, though, and dealers can easily put themselves above the rest with an investment--and therein lies the problem.
I have worked at a place (not a kubota dealer) where "good enough" was fine with the boss. He didn't want to put anything into the business, but had no problem investing a ton of the business income into his own personal payroll. That's his choice and I respected that 100%, much the same as I did the similar when I had my own place. But there comes a time, and Kubota is really pushing ALL dealers, that they've got to poop or get off the pot--which is happening now. That's why you're seeing some of the smaller mom-and-pop dealers go away. They got off the pot. Exactly the same as car dealers do every so often, you either invest in your program, or you go away.
I will say, Deere isn't much better, and Deere started all the same things Kubota's doing now, about 20 years ago (remember when they started selling mowers at Home Depot??--I remember it well), BUT, I do know that Deere's parts ordering system and vehicle ordering system is a little more organized than Kubota's is, but I also remember when Deere's was piss-poor, they had growing pains too just like Kubota is now.
