When servicing a vehicle for any type of customer concern, the following steps are imperative. Inspect and ensure the integrity of all related wiring harness connectors. If the wiring harness connectors are not properly put together or engaged before they are locked together, numerous types of intermittent conditions may occur, which may include any of the symptoms listed above and possibly others.
The first step in any type of electrical diagnosis is a visual and physical inspection of the wiring harness connectors for integrity. Many times, the vehicle may be repaired just by disconnecting and reconnecting the connectors. As with all repairs to wiring harness connectors and terminals, a pull test of the terminals within the connector should be performed. A pull test is performed by inserting the proper size terminal test tool (not a paper clip) into the terminal to determine whether or not the terminal is making good contact, or whether the terminal has been damaged from the prior improper connection or lack of connection.
Notice: Most terminals used in current module connectors (ECM, BCM, EBTCM and the like) are small 0.64 mm sq. terminals and can be damaged by probing with the wrong tool.
The J 35616-64A or B probe has been designed for these terminals that may be both a round or square design.
For example, if the Connector C2 of the engine wiring harness to the Powertrain Control Module (PCM), for the 2.2L equipped Cavalier or Sunfire is not properly seated into the PCM:
• The cam lock lever may close, however improperly.
• The cam lock lever may even snap out of position.
• The vehicle may have an intermittent condition with any one of the components which are controlled or monitored by the PCM.
THE CAM LOCK LEVER IS DESIGNED TO PULL (OR ASSIST) THE CONNECTOR INTO ITS FINAL POSITION ONCE IT HAS BEEN PRESSED STRAIGHT INTO THE PCM HEADER PAST THE INITIAL DETENT, ALLOWING THE LEVER TO BE MOVED INTO THE LOCKED POSITION. It is not only a retainer but an assist during the connection process . When the wiring harness connector is properly connected to the PCM, a snap will be heard when the connector is in position to be fully seated. The cam lock lever may then be closed. The cam lock lever will then do its designated job as both an assist and ensuring the connector does not come apart due to vibration or other types of conditions found in vehicles as they travel down the highway.
Remember, if a terminal (metal) or the connector (plastic) is damaged, they should be replaced. DO NOT replace the complete wiring harness assembly.

Wow, I agree. it's hard to give meaningful advice on this. I've got an 2006 Cobalt LT that I got new, and I haven't had ANY of the problems that you're describing at all. I've got a little over 12,000 miles on it now. My on board dash computer & lights work fine. The only issue I had with it was the key would get stuck in the ignition & I couldn't get it out. That was quickly fixed under the warrenty with less than a week of down time. You should look into the lemon law on this, it sound like your car picked up a wild pack of gremlins on it's way off the lot. So far my cobalt has been a fine running car. I have yet to get the 36 MPG they claim it has, but it's a respectable 28 MPG unless I totally baby it.
I hope this helps.

It's hard to give a meaningful advice - there are way too many possible reasons for that. Good news is sooner or later the problem will become permanent, and the dealer will have no choice other than fixing it. What I would think about if I were you is what are gonna do when it runs (or rather rattles) out of warranty? I - if I were you - would also think twice before buying another chevy or suchlike.

you are doing the right thing, just keep good documentation of all the times you have taken it in, who you talked with, how they acted, anything that may steer the c/s rep your way. they may make a suggestion as to something else to try, just go along with it expreess you dissatisfaction and how much its been a burden bringing it in, arranging rides, and relay the fact that they still are wanting a payment made when its in the shop and you cant use it.

The problem is the tech needs to talk to kdiesel sounds like more than one head is needed for this one. With out being able to check it by computer i would say PCM. New stuff has wierd problems sometimes that don't make any sense.

the worst problems our dealership see's involves aftermarket accesories such as stereo systems,remote starts,aftermarket power sunroofs,if you don't have ant of these accesories, iwould suggest leaving it for your dealer to fix and don't bug him to much.these problems are HARD to find,if it is more than a couple weeks though,I would pursue the GM buyback option,or lemon law.

If the dealer ship cant fix it in 3 attempts and has had reasonable access to the vehicle, they will have to buy it back!

call the LORDSTOWN PLANT in Ohio, they are the ones who make the car and complain to them about it and they might help you resolve the problems with it, they don't like to have customers complaining about their cars, I think GM Lordstown assembly has a website you can get a phone # from.
