Can anyone tell me what a flashing TPMS means? I dont think the pressure is low because I checked it, and I just got new tires about a week ago, and it was doing it before and after. It kinda bothers me, I'm thinking one of the sensors went bad. Any advice would help. Thanks!

Check tires when cold and if that doesn't clear the light, have a dealer check it out.
If the tire installer damaged a TPMS sensor, they should replace it at their cost, but unless the tire work was done by the dealer, don't hold your breath. Those sensors cost ~$100 each, so hope that it is out-of-range tire pressures causing the problem.
EDIT: "Therefore, the warning light illuminates when tire pressure is too low or too high in one or more tires, and flashes when there is a system malfunction." (The Manual)
Check you tire pressure. The TPMS sometimes leak if they are not installed corectly, they are finicky about the amount of torque applied to them. Get some soapy water in a spray bottle and check for a slow leak around the valve stem where it contacts the rim.
Second the advice from gonnahanvan8, the sensors are somewhat fragile. I damaged one taking an aftermarket cap off. Although I used thread ease when I first put the caps on, one of them bound up tight enough that I could not remove it by hand. Grabbed a set of pliers to grip it better and broke the epoxy seal between the valve stem and the body when I applied torque which resulted in a slow leak. They are not cheap to replace.
My car had the same problem. It would flash yellow after driving for a bit. The dealer told me that my tires were overinflated and they reset the system. That didn't fix it and I took it back in to find out that one of the tire sensors was faulty. They replaced it under warranty, but then again I had the stock wheels and had never swapped them.
