2005 Chevrolet Cobalt vehicle speed control problems

“The tcm in my 5 cobalt is not working properly I've tested and replaced everything els and had the tcm reprogrammed still getting problems aiming back to the tcm it wasn't looked at by a business”

“My husband was driving and the car suddenly stopped taking gas and said reduced engine power. He got it back home as it was only a few miles but top speed was less than 10 mph. It never did run right anymore and then completely stopped a few days later. Also the key gets stuck in the car if the battery goes dead. I had to leave the key in with the window down because I was scared of getting locked out. When my husband was able to come and charge the battery some it released the key. It never had any issues like these until they suddenly started. These issues showed up in summer 2021. Codes mentioned general electrical failure, throttle control issues with pedal and tac module. High and low voltage to tac module.”
