So, my radiator melted down three times in a year. I scheduled a replacement and realized I have two thermostats. It was super expensive to repair, so I only ended up replacing the front one. I really hope that fixes the problem. I also asked the mechanic to find out if it was the sensor.
Before the replacement, I got the code P0128. My engine temperature was cool near the problem, then went back up to normal at around 179°F on the highway. But on idle or city driving, it got around 185-199°F, which is normal for my car. Right when i have the radiator melt down. My temp needles jump up to redline so quickly before i can stop to cool it down, thus causing the melt.
It's been two months since the code popped up. I'm currently waiting to pick up my car.
I'm keeping my fingers crossed that it's either the front thermostat or the sensor.
