How to replace the latch on the center console
I had the same problem! I had to wedge a water bottle between the console and seat to keep the console lid in place!
I tried calling the dealership... I spoke with service who said "come on by and we can take a look. We can schedule you for an appointment on... [date two weeks away]. I asked if I could just buy the part and the sent me over to the parts department. They claimed to not know what piece I was talking about. The dude kept calling it a "console lock" (I found out later that this is indeed the correct piece), but he "couldn't in good conscience allow me to purchase the item without knowing exactly what it was. So he kicked me over to the service department. So, I said "screw this! I'm gunna figure this thing out myself!" And I did.
Step 1: Gather the correct tools
Small slotted (flat-head) screwdriver or plastic pry bar.
A pair of small needle-nose (or similar) pliers.
Step 2: Take the center console apart
Using the pry bar or small slotted screwdriver, gently... I SAID GENTLY wedge the hard plastic under piece of the center console and the soft rubber/vinyl cover (don't pull TOO hard, but you should hear plastic pieces start to pop or separate within the console assembly...).

Begin to gently work your way around the perimeter of the console. Eventually, you should be able to get your fingers in between the gab and pry the two pieces apart.

Completely remove the plastic piece that contains the console latch and take it to a safe working area. We're going to be focusing on the top portion where my hand is holding it up.

Step 3: Remove the latch assembly from the plastic backing
Take a quick second to look over the piece. Notice the main pieces you're working with are the plastic backing, a metal rod, a spring and the plastic latch itself. You'll notice one end of the rod is pointy and the other is abrasive. Take your pliers and squeeze the pointy side of the metal rod so as to push it inward (see picture below).
Pointy end of the rod
When you have enough of the abrasive end sticking out, use the pliers to pull from that end and completely remove the rod.

WARNING: There are small pieces. Pull the rod out slowly to make sure you gather the spring and the rod. If you lose either one, you'll have to buy the whole assembly as the new latch does not come with a rod or spring.

Step 4: Placement of new latch
Take a quick look at the spring and rod together with the latch below (assembled outside of console for demonstration purposes):

Notice the placement of the spring... The pointy end goes outward. If you put it in incorrectly, the latch will not work properly.
Set the spring on the back of the latch and place it into the plastic backing. Hold the spring with your thumb and run the rod through the hole on the left side, pointy end first (the way you found it, originally). The rod will run through the holes on each side and through the coils on the spring. It should look like the picture below half way through...

Push the rod as far as it'll go with your fingers and finish the job with the pliers, until the pointy end is showing on the right side and the abrasive end is flush with the left side:

Test to make sure the spring is working correctly by pressing on the latch release multiple times. Place the plastic backing back into the console cover and snap into place. Squeeze around the sides (similar to closing the lid on a tupperware container) to ensure it's seated properly. Close the console lid. As long as it stays closed and opens when you press the release, you're all done! If it doesn't work properly, go back through steps 1-3 to ensure the spring is set properly.
