4/14/17 vehicle svc-ignition recall 14113 lock cylinder & key 13454 ignition switch the vehicle was performing well prior to the recall service but now it appeared that the ignition was "stiff' to operate following the repair & the key seemed to periodically hang up when inserted. There was a random hesitation when making a u turn-as if the car briefly stalled out- no power, upon turning the wheel. Eve of 4/21/17, after being driven & parked on a city street for about an hr, the vehicle would not start although there was full battery power. The vehicle was secured & left to sit. Morn of 4/22/17 svc ctr was notified. Vehicle still wouldn't start, but, upon insertion of the key & initial crank, the car began experiencing sudden random clicks of the ignition switch, door locks engaging, dashboard panel flashing. Upon removing the key & reinserting it, the key appeared to have deprogrammed & the anti theft light was activated. The key was removed & the car secured. Later, attempt to engage the ignition using the second new key & was unsuccessful-the key would not turn to off position but locked in acc mode position. Later, the vehicle was towed per dealer auth. The tow truck operator noted that the car battery appeared to have drained by their arrival, the key would not disengage from the ignition & the car would not come out of park. 4/24/17 service found codes p0604 & p0606 control module ram failure + internal controller failure- dealer courtesy performed reprogramming, theft relearn & crank variation learn.

The 2005 chevy Cobalt, as well as possibly every other model year Cobalt has more problems than just the power steering motor failures. The speedometer no longer works in my vehicle, the low-fuel warning pops up no matter how much gas is in the car, the engine warning light illuminates, as well as the anti-theft light, battery light (the battery is brand new) and just about every light on the dashboard. Though this isn't a big problem, the radio locks itself and cannot be used until the car is turned off and turned back on. The car struggles to get out of first gear and has stalled repeatedly at red lights and on ramps to the highway. I have had the power steering recall repair done twice and when I took the car back to the dealership in may because the power steering warning had popped up again and the power steering stopped working, they said it was not the power steering and they sent me home in my stalling, jumping car with no power steering. Speaking to a chevy customer service representative, they told me to go have the car diagnosed (they did run a scan at the dealership and came up with codes u2107, u2100 and u2105) and that I should be responsible for the cost. I asked why they didn't suggest this at the dealership, and was never given an answer other than a repeated I should be held responsible and it's probably a bad ecm or bcm. The car is out of warranty and chevy offered 50% of the repair cost, but how is this a problem that I caused and should be responsible for at all? this car is incredibly unsafe to drive and I have read a number of similar complaints for this vehicle online. Gm must be held responsible for their faulty vehicles. The power steering recall did not take care of everyone's problems and the customers should not be held responsible for the manufacturer's failure. ## VIN failed ## Chevrolet Cobalt 2005 ##.

Tl- the contact owns a 2005 Chevrolet Cobalt. The contact stated the vehicle would shift abnormally hard and would often jump when driving at various speeds. In addition, the vehicle would sporadically attempt to stall. The contact stated that various warning lights would illuminate on the instrument panel when the failure occurred. The contact had taken the vehicle to the dealer twice and each time the dealer stated that they could not duplicate the failure. The contact also stated that the automatic key fob could not be used to lock the doors because the anti-theft alarm could not be disarmed. As a result, the contact had to manually lock and unlock the doors at all times. The vehicle was not repaired. The failure mileage was 65,000 and the current mileage was 71,000. Kmj.

The brake caliper was rattling because it was broke I had a auto repair man replace part then all of a sudden it brakes again that was for the front and back it also has elected electrical problems the windows work when they want and the car mostly always stalls it has even stalled on me in the middle of traffic on hwy what it does is act real sluggish and the more you press on the gas the more it bogs out and pulls back instead of taking off as supposed to the turn signals in the front always blow everytime replaced there is also interior electrical problems such as the interior lighting works when it wants to and the doors lock and unlock themselves with will unset the anti theft system and allow for prowlers to take the car.

Power steering light warning light comes on check engine light comes on, security anti theft light comes on all gauges fail, speed, gas,tack the car will run rough and stall car will not shift multiple computer error codes dealer replaced a computer component didn't fix problem. The car is unsafe to drive when problems occur.

Electrical system seems to be defective. When first bought car, the fan for the heater would not work. Finally, dealership took parts out of a brand new vehicle, since there were no parts made yet due to it being brand new, and replaced it. But, it still makes a whining when it is on #1 setting. The cd player would lock up all the time and simply say "locked". According to user manual, we are advised to take it to dealership and they will fix that problem. Upon taking car to dealership for that problem, they said there was nothing wrong with it because of course, it did not do it for them. So, we stopped trying to even use the cd player. The locked status occurs frequently for no apparent reason. Like, when going over a real bumpy part of the road. All of a sudden the lock button appeared on the dashboard. I was afraid the car was going to turn off on me. Sometimes the word "lock" comes on in the radio display and so the clock won't display. I have no idea what is wrong or why it is displayed. The real scary part, though, is when the dashboard displays the "lock" icon. Because I fear that the vehicle will just stop running since I read that it does have an anti-theft function that will stop the supply of gas to the car and I wonder if/when this will begin malfunctioning. Will I be on the highway traveling at 65 mps? I mean, more people need to let chevy know that this is happening so that it can be fixed. Lately, the vehicle will not start. It just will not start when we put the key in the ignition. All other lights and things turn on, but the engine won't turn over. Why, we don't know. Dealer claims we must have it towed to them and not get it jumped so they can take a look at it to see what is wrong. Has happened three times so far. Still no resolution to this problem. Feel that the problems are a result of the same defect-the electrical system. Guy that came to jump my car said the Cobalts have had lots of problems.
