Garmin dezl issue with weight limits on I-87?

I'm in the West, so haven't had that specific problem. But, have had too many odd routing choices to be happy with it. Just stuff that made no sense. Tries to get me to, instead of heading over the overpass and hanging a left to get on an Interstate in the direction I need to go, it wants me to hang a right, get on the Interstate, in the wrong direction, get off at the next exit and basically do a U turn at the exit to get back on the Interstate in the direction I want to go. Also shows exits that aren't closed, are closed and routes me the long way around.
IDK. When I got a Garman, it seemed folks overall thought it better than other brands. But, I find it too often isn't very good at routing me. Fortunately, many of the routes I take, I've taken before so know how to go. But, not all. So, gotta scrutinize routes I haven't taken before.
Basically, disappointed in how much I paid for the performance I get.

 

Garmin is junk.
Many false rout restriction, like it was I-80 not for trucks because overpasses in NE posted 40T. Some stupid coder put it in as 40 lbs.
Many NO TRUCKS restriction even the sign is on the residential driveway.

 

I-10 east of New Orleans same thing. 5 ton restriction,
