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.

Gm replaced ignition parts and shifter mechanism as per recall. Shortly after issues began with steering locking up, transmission not shifting and various warning lights flashing. This became more frequent and is now impossible to drive. My technician says it is a body or transmission control module costing well over a thousand dollars. There appear to be 100s of 1000s of the same issue as per search engines. I will contact my local gm dealership. If gm will not back up its product it will be the last gm in my driveway. I will trade in on a toyota.

While driving in town shortly after turning onto a 45 MPH road my vehicle, automatic, started hesitating while shifting into the next gear. It would shift but not like normal. Brought it into a repair shop to have a diagnostic ran to be informed it is a failure to communicate with TCM. Code u0101 and also u2100. After doing research there has been multiple complaints about this. So first things first replaced the TCM with a new one at the dealership. After replacement the vehicle is still not shifting correctly.

This issue seems to be a common problem with the 2005 cobalt. Please research any car complaint websites about this certain vehicle. Even though all the recalls have been taken care of, while in motion, at any time and any speed, the dash lights starts flashing and you get the message power steering on message center, tc light comes on, light that shows padlock symbol comes on, RPM needle jumps up and down, steering wheel locks up, motor surges and shakes, and you hear all types of clicking sounds below gear shifter. This is a very dangerous thing and chevrolet/gm just cannot seem to fix this issue or even find anything wrong. The 2005 cobalt needs to be recalled and any other year of cobalt having this issue. I will give you below the last date this has happened, but this has went on since we got the car in 2008. My daughter is in school in kansas city, and this issue has happened quite frequently lately. The only remedy is to pull to side of road, shut off vehicle and restart and hope it does not act up again. I just wonder how may deaths have happened already because of this faulty gm product and no one knew it was because of what the cobalt did, locked up on its driver.
