It will be almost 2 yrs (in Jan) that I bought my 06. I just took it for the 5th time to the dealer for the stalling of engine. I had problems with daytime running lights, CD player died, 4 times engine stalling with no lights turning on. Sensors were changed and the last visit I had (supposedly the gas tank and fuel pump replaced)
I don't know what to believe anymore. The dealer is very nonchalant about it and my salesman claimed the did nothing wrong & my response they did nothing RIGHT! Also asked if I wanted to trade car in and I said I should get a 2008 with no loss on my end and they didn't like that either. Heard again that they never get complaints and I'm the only one so I showed them the Edmunds complaints, no comment. I did contact 800# at GM and if there is a next time, I was told to open a case with Better Business Bureau. I do believe I have electrical problems also.
I even chose the bare bones package with no electrical windows etc so I would have less problems! Guess that didn't work. I also made the mistake of chosing a dealer with inconvenient hours never thinking I would be there so much!
 
Contact GM and BBB to start a paper trail. In PA, the lemon law is 1 yr/12 months so I don't qualify, I have 21K and am concerned about our winter coming up in the next 3 months. I hope they get it right this time.
 
I love the dealerships responses, like I have nothing better to do & make this stuff up about my car, barely missing 4 accidents with this car stalling.

Gas Gauge by gerald41

For anyone with fuel gauge problems there is a TSB out on it. I had it repaired in my car an 06 Cobalt. The fuel sensor is defective and has to be changed. I would fill my car to the cap and 15 miles later it would read a half a tank. I had no confidence in it till I had it repaired. I was told by a tech that the 05 and 06's had many issues that the 07 and 08's had most problems remedied. I had the radio changed because they found a short in it and the Keys stuck in the ignition as well.

2005 base COBALT electrical and keys by raydes

I have experienced fractures in keys followed by broken keys. The car also randomly displays ''LOCK'' on the radio but the action of turning off the car and starting it again makes the condition vanish without any code entry or anything else. The 2005 COBALT recently stranded me when the one good key I had broke off in the ignition. The dealer laughs and says he cannot fix what is not broken as the radio issue will not replicate in front of him. The key problem is explained by the dealer as " the only time this ever happened in the history of all COBALTS and therefore I must somehow be at fault''. GM/ CHEVROLET apologizes heavily and frequently '' that I am not satisfied" but follows with a nice two step of bewilderment and a promise to call the dealer. I was told today that the dealer told GM that he was too busy to talk to the GM representative yet but a conversation was promised. I could be stuck with a non running, broken ignition key car in a blizzard but GM is not able to arrive at a point of communication with a dealer they have a legal agreement with. The problems with building small cars persist at GM and it is interesting that the competition taking market share from them in various U.S. product segments today was founded on building mostly notable small cars.

06 Cobalt battery woes by mongokg

My 06 Cobalt is going thru the "shifter ordeal " in that I cant get the key out due to the shifter being broke . My problem now is , while I wait for the dealer to get the parts my battery drains cuz the clock on the radio wont shut off . I jump started it twice(once with dealer mechanic ) , the second time by my self (11 o'clock at night wouldnt you know it). This somehow created a whole new problem ! Now the dash says "Engine Power Reduced" and the throttle does not work . I looked this up in the book . It says this is happening to avoid engine damage . How do I fix this and why did this happen ?

2006 Cobalt turning off by ameliat

I have a 2006 cobalt which i bought in Jan 2006. Since April 2007 my car has turned off 6 times. Once when i was on a highway going a 100km. Dealership says nothing is wrong. I told them i did not want to drive it because it was unsafe. He told me it was "my perogitive". I have been in contact with GM and they told me there was nothing they can do until the dealership recognizes the problem.

I've seen and heard of a similar issue with several 05 & 06 Cobalts doing this. In almost every case it was the ignition switch not making contact.
 
Have found the condition is more likely to happen with those that have a lot of junk hanging on the key chain. Not saying you have a lot of junk on your key but that has been an issue with several cars besides the Cobalt.

Hi thank you for responding to me. When i first had this problem they told me that it was due to my keys and how many i had. so i removed all my keys except to turn the car on. Since than it happened 6 more times. It happened again last night at 11pm so i took it to the dealership this morning after contacting gm again. They put a black box in my car in june. this black box is like the ones they have on airplanes to record data if a plane has engine problems or crashes. this box however when you hit it records what happens before hand. I had the box plugged in last night so when the dealership read the data this morning they decided that for the past 10 months my car has been turning off because of a faulty throttle switch. i don't know if this makes sense. they are replacing the parts and guess i will have to wait and see. If anyone else is still having this problem i advise you to go to your dealership and demand a black box or call GM until they listen. Personally i'm not going to stop until I know they are going to do something to fix all the cobalts.

so, your cobalt was still partially on and it was okay to jump it?

It now has 92,000 miles on it. I drive for a living, and this little car was wonderful for the first year that I had it. With new snow tires on it, it out climbed my husband's Suburban in the ice and snow. I did notice that, at night, when turning on the brights, all the lights went out. The next summer, I had a constant pool of water in the passenger side front floor, whenever the ac was ran everyday. It started dying on me at intersections, and slow uphills. In the fall, the shifter pin broke, and I was going out every 3-4 hours during the night to start it to keep the battery up for the next morning. I took out the console and manipulate it with the little lever thing. Then, the power steering stopped working when it died. I now have days when the locks click constantly, or just when I think I can hop out with it running for a delivery. Then, I am locked out. Now the power steering goes out when I am driving around a curve. It died on me today seven or eight times, in dangerous intersections, backing out of driveways into traffic, going up subdivision hills. I have called out of work indefinitely, to try and get another vehicle going somehow. I paid cash for this car, not enough stash built back up yet to replace it. I am just wondering if changing the throttle switch will remedy the dying problem. I have taken as good of care of this car as possible, I am feeling such disappointment. You would think a car you pay cash for would at least last 100,000 before falling apart. If anyone has had the throttle switch changed, could you let me know your results? Thanks!
