Automatic Transmission Cooler problems of the 2015 Jeep Patriot

When it is hot out 85-100f, my transmission overheating light goes on while driving at expressway/interstate highway speeds. The engine temperatures are within normal limits. It occurs without the a/c on. When this situation happens, my vehicle will no longer accelerate and will become slower and slower until I'm going >20mph. This is hazardous on high speed limit congested roadways. This has happened to my 2015 Jeep Patriot freedom drive 2 cvt at least 5 times during hot spring days or the summer. I have had to park on a shoulder of an expressway for 20-30 minutes for it to cool down so I could safely reenter the highway. I have heard of two other people with this issue and I do not know many people who have this model. All vehicles should be capable of getting to highway speed on an on ramp and merge in. I do not know if it is a cooling issue, a thermostat malfunction, or something else. I own the latitude, trail rated model, 2015. I bought it with only 2 miles on the odometer and I do regular fully synthetic oil changes. When I know the issue is starting I hear a distinctive winding sound when accelerating. Almost like the sound a drill or remote control car makes (like it's stuck in 1 gear, even though my car is a cvt I usually feel a "shift" when accelerating or passing. When this occurs, it sounds like something is restricting the "gears" and causing the winding/whining sound, like if you put a manual transmission into 1st or second and kept accelerating up to highway speeds.
