As noted by others, the splits in the posts are the least of your problems. This is at best a strangely designed and constructed deck. The framing design is poor at best, there are numerous inadequate connection details, nails are missing from connectors etc. You really need to bring in someone who knows proper deck construction procedure to fix the problems before your deck falls over.

Typically the posts should be connected with a metal bracket on top of the footing so the post is not inside the footing. See the attached photo link.

Do you have any pics of how the deck is secured to the house ?
Ledger board thru bolted ?

Danger is if not secure to the house, & given the lack of metal brackets from beams to joists the whole thing could pull away from the house & collapse

Also, why do none of the trim boards meet? the guy who built this deck did a weird job doing all the trim.

IMHO I think you should have another contractor look at this deck because it needs to be fixed. If you paid a lot of money to have this built you dont want anything to happen to it.

The ledger board is 2x10 and is attached to the house with carriage bolts in each box sill. The ledger board was installed by the builder when the house was built and I know this was done properly. What can be done to help strengthen the deck at this point?

Support the deck pull out the posts, attach the proper brackets, notch the posts like shown above, and carriage bolt the posts through the beam into post.

Posts are buried...so I doubt that is going to happen
You need metal brackets attaching the beams to the posts, & joists to the beams
In some cases the support may need to be replaced/resupported

You really need someone one-site to look at this IMO
Too much going on to see it all

Problem with the brackets is that the post is not sitting directly under the support beam so its offset so that wont work. If the guy who built you house built that deck I would call him back in to look at it. If he refuses find out what the code is in your area and if it doesnt meet code he has to fix it unless its beyond the statue of limitations in your state. Looks like a newer house so you should be within your rights to have him back to fix it.

The law at least in NH and MA is that if the contractor builds something that doesnt meet code or standard construction methods you have 7 years to make a claim to them (ie statue of limitation is 7 years)

All the joists are in joist hangers at the ledger board, but the joist are not in hangers at the perimeter of the deck (where the rail is). Should there be joist hangers there too? I will get some heavy duty L-brackets to take care of some of the problems and will have an expert take a look at it in the spring.
