I ended up bleeding the cooling system and now it works perfectly. Easy to do as well! Thank you so much for your help!

Thank you, I will look into those options as I find it hard to believe that the thermostat would go bad after only 6 months. I would imagine air in the cooling system.

My 2013 LS takes a while to heat up and even when it does it only blows hot air while I am accelerating, or the engine speed is high. Radiator fans constantly blowing on high. I replaced the thermostat 6-7 months ago for the same issue. It fixed all my problems immediately. Wondering if it could be a coincidence that the thermostat when bad again or if I need to be looking elsewhere for other issues? Thank you guys in advance!
