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.

Transmission control module failed. When I was backing up, I felt a jerk and when I put it back in "drive", the "d" indicator light was blinking. I took it to the shop and they said the tcm had to be replaced.
