Chevrolet Cobalt Electrical Problems

    I have a 2008 chevy Cobalt bought new in Sept 2008. The very 1st winter check engine light came on but went out by the next day.I called the dealer and they told me because the light went out they could not check to see why the light came on. Now a few weeks ago we had temperatures below freezing for a week. My check engine light came on and stayed on.I paid $95 for a diagnostic and was told the secondary air valve was corroded shut and was rusted due to moisture in the system. I have a problem with the ignition turning but that is covered under the recall,however this problem is not covered estimate $550 So I email GM,they offer to pay for everything except $200 My argument is the car has less than 40k miles on it.Why does a part that corrodes so easily cost $500 to replace? So I leave.The very next day the temp rises above freezing and magically the check engine light goes out,and stays out. Two days later it's raining pretty hard and I am travelling down a steep hill.My brake light comes on and stays on for a few seconds,goes out,then the brake fluid low light just flashed briefly and goes out. I check the brake fluid and master cylinder is full. I report it to GM and my dealer.They insist my car has more problems.The next day the tire pressure low warning light comes on and stays on.I check the tire pressure,and it's normal.I go to a local gas station to check tire pressure but their pump is malfunctioning.Go back next day. Check pressure,it's normal and as soon as temp outside rises above freezing,pressure low light goes out.I think my car has a sensor problem that occurs when the temp drops below freezing. GM will keep their offer to pay $300 of the $500 original estimate,but I may be paying $300 for something that isn't broken! I think GM should recall the Cobalt. Too many issues. I still owe 5k on a vehicle that's trying to nickel and dime me to death and it has less than 40k miles on it! speakers take turns working and not working when I had it 2 yrs. :lemon:
  • My stereo speakers take turns on which ones want to work,front to back left to right.Right now the only speaker working is the left rear speaker. GM stopped making this car for a reason,and now I'm beginning to understand why!
  • I sued gm and the dealer both denied but settled oout of court. got all my expenses plus a few more dollars. will never buy anothe rgm product. no quality control or inspection at factory. gm just rolls them out and hope for best. enough complaints then recall otherwise all repairs on your own.

    >I sued gm and the dealer

    What was the court name and location and the names on the suit? This would be interesting to see the claims that GM and the dealer settled on. Case/docket number? Attorney name? or did you use small claims?

    I purchased my car in feb. of 2009 and it had 29,000 miles on it. now four years and a 100 thousand miles later i am having nothing but problems. about a year or so ago my car started cutting out real bad while i was driving and took it to a mechanic. in town and he couldn't find anything wrong other than just so happened my ignition locked up and had to be replaced.. a week later a recall letter was sent and no i did not get fully reimbursed. well then the real fun started. every time i get gas my car will not start. it wont turn over and when it does it sputters and dies. after that now just when i go to get into it it will start but then start idling really hard and my rpms go up and down and then it will die. just today we got gas and my fiance decided to leave it running but as soon as he pulled the gas cap off it hissed letting out air from the pressure and my car died. I've taken it everywhere and either it doesn't do it when its there or they have no clue. i owe more than its worth and i cannot keep having to take it to places just to pay money for someone to tell me they don't know. also not long after i got it my front speakers would only work when they wanted to and now my back ones for a year or more now are the only ones that work. my cruise control don't work it will show its on but the reset and set button will not turn it on. however the buttons below it work. wire problems are my guess but as for now keeping it running and not getting stranded is my main concern and im hoping for some insight if anyone knows or has any suggestions. Its GREATLY APPRECIATED!!!
  • My daughter almost died today!!! Her car decided to go into total engine failure with little to NO brakes and very little steering wheel capability. She is 97 lbs with no upper body strength. She had to go off the road flip and hit a tree to avoid hitting other drivers on a very busy 4 lane. I just called and was advised there was no open recall for my VIN#...hmmm..I am very very suspicious that the entire system shuts down and nothing is wrong. Hardly makes sense. Better believe I WILL have this investigated by a professional, and if I find fault or defect, I will sue! My daughter's life is worth more than that piece of crap!~ Additionally, think of all of the other innocent drivers on the road who could have fallen victim to this defective piece of crap~~ BEWARE~

    Ok, so my tailights no longer light up when i turn my lights on, but my brake lights signals and reverse lights aswell as my headlights work fine. Although the halos on my headlights seem to be out but im not sure thats connected. My radio works fine and the DIC and lights for my AC defrost, airbag and air circulate buttons light up aswell as my warning lights. but the rest of my dash is out. ive tried the dimmer and replaced the "clster" fuse. Did i replace the wrong fuse or is it not fuse related. My dome light also works fine.

    Anyone know which fuse it is?
  • rdesantisrdesantis Posts: 30
    Okay, took the Problem to the dealer.... Quoted from recipt:

    "Cause: scan, no codes, no park or interior lights, check PL fuse, ok, check BCM, no power at X3 A7, trace wire back to under hood fuse block.

    Correction:repair poor connection at X5 D1, Check all lights working oK.

    It was 0.8 hrs...just charged m72$ for labour....unfortunatly my factory warranty expired 30 days before repair :(

    u will have to sue. no customer service and u can write the 3 top officials CEO dan akerson down and get no help. general motors is set up to hear and not react until u sue. be sure to quote state statute numbers with your complaint. they will settle out of court as they did with me. I should have asked for more but I just wanted to break even. even the dealer refused to help.

    The first correction failed. Same problem occured. could not diagnose the exact issue. Since dash and tail lights operated on the same fuse, mechanic separated fuses (ran dash lights on its own fuse), one for dashlights other for tail lights. that way problem could be traced, if dash lights blew the fuse then it was that fuse, if tail lights blew its own fuse, then we would know if it was an interior or exterior issue.
    Took it home and it blew again!! Took back, tech trace problem back to tail light fuse therefore an external issue. he was going to replace an entire electrical line ($$$ in labour) and happened to do one more look around vehicle and noticed and kink and exposed wire in the trailer harness wiring. Patched the exposed wire and lights on (with another replaced fuse). Lets hope this helps ;)
  • Hi, I'm having a very similar issue on my 07 Cobalt.
    After Dealership replaced Fuel pump Twice! It ran badly and would stall out.
    Then the Windshield wipers would go into Insanity mode.
    The dealer said "Replace the Fuse Box."
    $500 dollars later, Im broke.
    I want my money baack!!
    Did you have any luck?

    I tried to go to this site but it shows it as a URL that is available for purchase. Is there another way to reach you?
  • I have an 05 Chevy cobalt. Was driving it on the freeway and as soon as I got off it shut off on me. It turns over but will not start. It is throwing no codes at all. But it has no power to the fuse box under the passenger side by the radio. Any ideas why its doing this? Anyone know? Please help. I have been without a car for over two weeks and even the mechanic has no idea.

    Hi - it should be socialmedia at Replace the word "at" with the "at" sign in email addresses. Our graphic for that isn't working at the moment.

  • Your sputter and start issues are exactly what was happening to ours around 60K. We did the plugs, took good car of the cobalt. Anyway really scary one day pulling out of a parking lot, making a left and gave it some gas and sputter sputter (cars approaching, ahhh!) then it kicked in and went. So, that was it for us, we sold but not before finding the cause. Here is what it was, the issue was the coil packs, they deliver the charge to make the spark plugs fire. As explained to us the part the generates the charge was ok but it runs through a plastic holder and given the proximity to the block the plastic can break down and cause a short (so the associated plug will not fire or fire intermittently). Dealer showed us the old parts, it is bound to fail for everyone at some point. Fix was about $170 dollars and as explained should be good for many miles to come. Ran the car for about 2 months after that until sold. Also had the stereo speaker issue others here have noted, never looked into that.

    We have a grand cherokee now, it has issues as well. These static plastic blocks in the power window mechanism, no joke with a metal cable running over them,,, yeah that will last, they are failing one at a time. Transmission issues all well documented here on Edmunds. Neighbor runs a late 80's F150, manual 4 speed, has some rust issues but the thing has out lasted our last 2 modern vehicles. We've pretty much thrown in the towel on getting any type of reliable life out of any modern vehicle. Good Luck!

    My wife's 05 Cobalt's stereo stopped putting out sound. The radio lights up and appears to be working fine. (I can switch stations, insert cd's, etc but NO sound) I found a blown Amplifier fuse in the passenger side console fuse panel and when I replaced it, it immediately blew. Obviously a short somewhere, but where? I checked another site that mentioned the amplifier power wire leaves the back of the fuse panel and over a metal bracket that can, in time wear through the wires protective coating causing a short. Has anyone else ever heard of this? If so, where exactly is the bracket, and how do I gain access to it?
  • I have a 2005 chevy cobalt and I would greatly appreciate any advice I can get. When it is really cold outside my car don't want to start or it will die once I start to slow down and then the other day the gas pedal got stuck to the floor. I took it to auto zone cause the engine light was on but it wouldn't read anything. It has also locked up on me where I couldn't open the doors. I had to go to the window. In order to get it to start I have to smack close to the CD player near the passenger side.
  • This car has been a piece of trash. It has had recalls, problems upon problems. A/C problems which somehow repaired tehmselves with the steering coloumn recall. Which the dealership said had nothing to do with it. Of course they also broke the part the turns my blinker off after you turn. Then it had the fuel pump leak which the dealership said was the worst one they had seen. They were amazed it had not caught fire. Funny cause I had taken it to them 3 times because my gas mileage had become so bad being told all 3 times nothing was wrong. Yeah that was the horrible gas leak. Now the last 3 months it has started trying to die when i pull up to a stop sign. Hmmm after researching the other problems of Cobalt owners figured it was the throttle controller. NEEDS A RECALL AGAIN! Sure enough coming home the other night my6 engine light came on. Guess what the code said. engine throttle controller. Oh did I also mention I just had a $450 bill to repair an a/c line that just cracked into. The car that keeps on sucking money. When is Chevy going to give us $10,000 off a new car? Can I apply it to a FORD? Signed so very disappointed
