Chevrolet cobalt: My 2009 chevy cobalt 2.2L won't even turn

Customer Question
My 2009 chevy cobalt 2.2L...
My 2009 chevy cobalt 2.2L won't even turn over,key gets stuck in ignition and none of the interior or exterior lights will turn on. This doesn't happen every time and then all of a sudden the vehicle will start. I've verified that the battery is good and I have had the ignition lock replaced due to the recall. Seems like I've had these problems since they replaced the ignition last year. I think it may have a short because the brake light would flicker when it was sitting in the driveway with the ignition still stuck in the on position. Any other suggestions on what to look for? Also verified battery connections are clean and not loose. Help please!!

Welcome, I'm Chris (aka Moose). I normally log in after 3 pm central. Please make sure to let me know exactly what is needed from me so I can provide EXCELLENT 5 STAR service. When the key gets stuck, unable to be removed. Will the key still turn to different positions?When the lights will not turn on, does the instrument cluster respond to the key in the run position, does the radio work?

When the key gets stuck it will turn forward to ignition but it won't let it return to the off position to remove the key. The instrument panel doesn't respond to the key being turned
Customer reply replied 1 year ago
Nothing works at all. But I wait 20 minutes and try it again and sometimes it starts up and runs fine. Like it just did. Fusable link maybe?
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago
I believe the key will not allow returning to the off position due to the ignition lock solenoid not energizing from this loss of power issue. When nothing has power, have you checked the fuses under the hood to see if they are powered with 12.6 volts? If not and the battery cable connections are clean then the issue would be the fuse box to blame. If the fuses do have power during this issue, let me know. -------------------------------------------------------------------------------------On your screen at the top you should see a rating 1-5 stars and a green submit button.

None of the underhood fuses were receiving power. Only way fuse box could be bad is if water got into it. Right?
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago
A fuse box can fail for many reasons, water getting into it is only one possible cause.

Would a used replacement box be ok or should I just get a new one ?
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago
I see no problem with a used part.

Still wondering why it's not a constant problem with it starting, because it's starting and running fine now but probably won't tomorrow
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago
Intermittent concerns are the hardest to diagnose. If the fuses had no power then it has to be the fuse box since its wired direct to the battery and you already ruled out the battery cables to blame.

Would that explain why the taillight was flickering when it was just sitting in the driveway with the key in the ignition?
Chevy Mechanic: Chris (aka-Moose), Technician replied 1 year ago
When you have a fuse box issue its hard to diagnose why other issues are occurring but yes the fuse box can be to blame.

i have actually seen this happen on another gm vehicle in person and it ended up being a combination between the ignition lock cylinder and ignition switch. they both had to be replaced together. i could never figure out why it was intermittent but all i came to conclude was the contact in the ignition switch were worn out that is why.

Customer reply replied 1 year ago
I never had a problem with this until GM did the factory recall replacement of the lock cylinder
Chevy Mechanic: mike switzer,
 replied 1 year ago
then you may only need to replace the ignition switch if the cylinder has been replaced. to be honest they may have damaged something during the recall but i am not there so i wouldnt be able to tell if it is damaged or not.

This issue would be the reason why the interior lights wouldn't even turn on also ? And cause the key to get stuck in the ignition?
Chevy Mechanic: mike switzer,
 replied 1 year ago
interior lights yes and surprisingly yes it prevents the cylinder from turning back all the way to release the key.

Customer reply replied 1 year ago
I should replace the ignition switch and the ignition lock cylinder just to be sure?

Hi John, My name is***** will be glad to try to help on this one In the shifter linkage in the center console there is an electrical switch and a lever that is made pretty cheaply that causes a lot of these problems. If that switch or harness is faulty or not mechanically being fully engaged due to wear, it will not allow the ignition switch to release the key as it is not reading the car is in Neutral. There is a lot of problems with this model for these same symptoms. I recommend you inspect the shifter for wear or broken parts and verify it is engaging the switch to read neutral. Test the switch and inspect the harness and connector pins for corrosion and damaged wires. With the GM diagnostic software the switch status can be read in live data to confirm all this if you would prefer to have a dealer run a quick diagnostic. If you prefer to check this yourself you will have to access the shift linkage ans switch inside the center console. Let me know

How does that explain having absolutely no power to anything in the car. No dash lights, no interior lights and power only to the steering assist and nowhere else on the column. Already checked all ground connections and even ran a direct ground from the battery to the starter and still no power coming from fuse relay box to the column

THESE VEHICLES FAIL TO COMPLY WITH FEDERAL MOTOR VEHICLES SAFETY STANDARD 102, "TRANSMISSION SHIFT POSITION SEQUENCE, STARTER INTERLOCK, AND TRANSMISSION BRAKING EFFECT", AND FMVSS 114, "THEFT PROTECTION AND ROLLAWAY PREVENTION". ON SOME OF THESE VEHICLES, THE TRANSMISSION SHIFT CABLE ADJUSTMENT CLIP MAY NOT BE FULLY ENGAGED.

WITH THIS CONDITION, THE DRIVE COULD MOVE THE SHIFTER TO "PARK" AND REMOVE THE IGNITION KEY, BUT THE TRANSMISSION GEAR MAY NOT BE IN "PARK".Action Needed To Fix It:DEALERS WILL INSPECT AND ENSURE THAT THE SHIFT CABLE ADJUSTMENT CLIP IS FULLY ENGAGED. IN THE EVENT THAT THE CLIP DOES NOT ENGAGE, THE SHIFT CABLE WILL BE REPLACED FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN ON OR BEFORE MARCH 24, 2009.

Have you tested all your fuses and relays under the hood and tested power and grounds to the Body control module?
Ask Your Own Chevy Question
Customer reply replied 1 year ago
Already checked the BCM and had power to everything. Already had both of those recalls done and after they replaced the ignition switch is when the problems seem to have started. But they were GM certified and couldn't have possibly screwed anything up when they did it "blah,blah,blah"
Customer reply replied 1 year ago
The only fuses that intermittently lose power when everything on the dash does are the ones labeled IP Ignition in the fuse relay box under the hood
Chevy Mechanic: Daniel Wilson,
 replied 1 year ago
Thanks for the update John. If the harness and grounds all check out then the problem is highly likely in the BCM itself. Try having the software reflashed and see if it will take a reflash or fail reprogramming. If successful, see if the problem remains. Let me know

Customer reply replied 1 year ago
Is it possible to reflash myself or do I have to take to dealer ?
Chevy Mechanic: Daniel Wilson,
 replied 1 year ago
The dealer or you need to have the Tech 2 software to do it.I am not 100% sure all parameters and programming is accessible with tech 2 either. You will only be paying them what they charge for the reflash of the BCM and at the same time you will know if a problem is detected with the BCM.

Not sure if you have access to a truck but a uhaul dolly is only about 50 to rent. Much cheaper than a tow bill. Just a thought.

It ended up being a wire that ran from the BCM to the fuse box underneath the floor carpet that was worn and shorting out. You were at least helpful, but the first guy had me buy $70 in parts that I didn't need. Not your fault, but I think I am going to ask for a refund to help offset the cost of parts and $240 in labor at the dealership

When another expert opts out the question goes back on the same board for all experts to see. No one has gotten a dime for their time as your deposit sits with the site and gets split with the expert you would leave positive feedback or accept an answer. I help out on here in between jobs and as time allows for some extra cash. I agree its not my fault and I did take the time to post and research the BCM diagram and get you back in the right direction with your troubleshooting. I think in the future I will think twice about grabbing opted out questions under circumstances such as this.
