Wiring Problems of Chevrolet Sonic

I bought this car used back in October 2017, I've had overheating problems, the dealership fixed twice under an extended warranty the third time I had to fix myself (they said my extended warranty expired). I noticed my key would get stuck in the ignition after putting the gear in park, I discovered the button on my gear shift is cracked and I have to pull it all the way put to remove the key. The latest adventure is I was driving on the highway in the fast lane at about 75 mph when my car made a pop noise then slightly jerked then started to slow down. The check engine light came along with the traction light, I was able to safely get over to the shoulder I parked and cut the car off. After a few minutes I was able to start my car back up and get it to an auto store to find out why the check engine light was on. The codes that came back stated communication was lost with the tcm and the tcm internal temperature was too high. I was told the most likely solution is faulty wiring at the tcm. This is becoming a headache I'm still paying on this car and doing more repairing than scheduled maintenance.

My wiring harnesses have been chewed by rodents twice in less than 10 days because gm uses soy based plastics to coat the wiring harnesses. Soy products are used in the making of rodent foods. My car stopped dead in traffic because the wires broke due to the damage (found later at dealership). It was fortunate that I was just pulling away from a stop in my neighborhood when it occurred and not once I had reached interstate speeds where I normally drive to work. There are thousands of complaints online concerning this same problem.
