mss burr: I have a 2008 Chevy cobalt. And I am having all types of electrical issues. the tire pressure sequencer is in the driver side door needs to be replaced in order for the light to go off.. the Signal indicator does not sound anymore. The front speaker just stopped working.. and according to the internet this is a common issue. The transmission is acting funny. I hate that I bought this can.. and of course once the warranty ends. it all goes to crap. But all of the issue I am having with this car. Is common on the complaint boards... GMC knew the issues. And are not going to fix it for free. unless somebody dies and then they will issue a free recall.
Sergio Peña: thanks , it was very helpful her totorial , follow up these very useful tricks, Saludos desde Durango Mexico brother....
Smilin Charlie Lockwood: Local mechanics had no clue " my" FIX was because of bad ground. Reset computer by disconnecting battery overnight then take a wire and ground the Transmission Control Module to grounding screw on engine block. Might not work for you but did for me. Another fellow has this solution on Youtube. thanks Youtube!
Mary Ann Murphy: my cobalt Lt is doing the same electrical problems 3 mechanic's later and still having the same problem what is up with Chevy and there cobalt issues
Cantralle Tease: So how can we fix this what can we do about this I'm out of about 4000 dollars an I'm still having the same problem........ we need to file a class action lawsuit against the dealer they need to pay for this......
Zackasee_: I work for a used car dealer. I drove back a 2010 Cobalt Sedan with 33,000 miles on it, two hours from the auction to our dealership. This same problem occurred about twenty minutes after I left so I was scared out of my mind the rest of the way. Tranny clunked and jerked, power steering illuminated on the dash, the car even went into limp-mode a few times on the highway, while I was going 60+mph. The coupes look nice and the SS models are fun, but those are the only good things I can think of about the Chevy Cobalt.
Pearl Gonzalez: My 2006 cobalt all of a sudden jumps when I step on the gas. sounds like it's losing power???
James Nemeth: Michael Hodges, No offense but your friend is just stupid. Only a crazy person would think anything like that... Truth is. anything electronic, failure is imminent eventually.
Michael Hodges: Friend told me they set the cars like this to steal money from customers. The miles are on the computer and they take their time on your wallet already preset
Nikki F: my check engine light just came on this morning. I own a 2006 Chevy Cobalt LT. 2 Dr. should I go to Advanced Auto to let them test it?
Souleye Oudraogo: I turn the ignition on ..but the check engine light is off ..the problem is I was putting a new horn on the the the positive touched the body of the car nd now the problems started ..the car won't start at all ..what should I do ..u think that the pcm is scratched..
Joe Nardone: A friends car had a similar problem, researching I found that either a pitted fuse for the "transmission control Module or TCM" or a loose wire can be and was our problem!! The fuse was fine!! but one of the wires I aimlessly moved around did move, the car has worked well since, the problem is I don't know which wire it was!!! but have pinpointed where the problem is, "in our case" Along side your transmission shifter on the passenger side is a panel to gain access to your Body Control Module or BCM. " Google Colbalt BCM Location and check images" the fuse number for the TCM is 25 if the fuse is ok then check for a loose wire in the BCM!! Hope this helps someone!!!
Martin Salas: para reparar este problema hay que abrir el modulo TCM, biene muy bien cerrado, pero hay que abrirlo y en la parte de adentro hay que soldarle un pequeño alambre que es el que hace la tierra con el conector exteror, se troza por eso marca este error, yo ya lo hise con mi carro y funciono
Juan Torres: Ive been having this problem. I took it to the dealer, the mechanic hasnt given me a call back. The scanner code that appeared was u0073 communicaton modle bus off. I called and emailed GM well as NHTSA. Just waiting for a response. I hope they make a recall on this issue its unsafe to drive like this. I did my own research. I came across that alot of people changed the TCM and problem was fixed. But some suggested to clean the fuse box the BCM and ECM. Check the ground wires and Transmission wires. I did that and drove the car a few blocks and it seemed ok.... For now... If the issue continues I guess I'll have to buy the TCM ugh.
Amber Webster: Have the same problem here with a 2008 chevy cobalt never again in my life will i drive or own a chevy this never would have happened with a ford. Whats the fix to this
My car has had this problem since 40k miles. It now has over 70k miles. Ill be driving down the interstate and the power steering will go out. This isnt safe, but when I called GM they said "tough luck". Report your problem to NHTSA at 18883273246 if they receive enough complaints GM will be forced to issue a recall.
