#225 of 361 2008 Chevy Cobalt Stereo/Speaker/Electrical Issue
Jun 03, 2011 (5:02 pm)
Hi, I own a 2008 Chevrolet Cobalt LT 4 door Sedan. I purchased it in May 2009 with 29,110 miles on it. I am having issues with my speaker system and my stereo display. My stereo display flickers frequently then displays fine. My speaker system will intermittently not work in the front for about 30 minutes of time while still working in the back. At first I thought this was an issue with maybe a fuse but the speakers in the front will still occasionally work. My speaker system is the default that comes with the car. My car also has a history of electrical issues according to the carfax report when I bought it but I don't have a copy of that and don't know what the specific electrical issues were.
Also, is this something that could possibly be covered under my GM Extended Warranty? I would like to know before taking my car to a dealership to get looked at. My warranty has been great as my remote for my car died last year and the dealership where I use to live was able to replace free of charge to me under the warranty.
I appreciate any help as I have little knowledge when it comes to these things. Thank you in advance.

BCM has finally been replaced but didn't solve all of my issues. Now they tell me it's the TCM and for another $450.00 they will change that too. A total of around $1200.00 and I will be good. They had another TCM there and plugged into my car and they said everything worked fine. So hopefully, this will all be took care of.

Driving today temp in the car registers a blistering 101 outside. So of course the ac is on and like any Cobalt I've ridden in, not the best. It starts going cold to hot to cold and hot again. 'bout half mile down the road I notice the speedometer start to ocilate between roughly 30 to 85 miles an hour. Holding the throttle steady I know we were still doing about 65. Seemingly the same time the car warns of a power steering fault. All goes away a few mins later then then the tranny starts to slip in and out of gear. We get to our destination finish getting a gallon of milk and go back to the car. Ride home windows down and NO AC. No problems. The only thing connecting all systems is power. Called our dealership they can't see me till Tuesday. They also "said" that they replaced the power steering yet did not know this due to the fact that I never had a problem so I would ride it out. So where does one go from here? Not going to pay thousands of dollars for someone to guess what the cars problems are! What happened to standing behind a product? How many problems need to be addressed before a company says hey we have a problem? Can anyone help? If so thank you in advance!

As you can see from my earlier post, and those of others, that there is a problem. Unfortunately, I bought my '06 Cobalt as an insurance rebuild, so GM washes their hands of it (even though it was body damage). My major beef is that I refuse to believe that "trained" GM "Mr. Goodwrench" mechanics have to guess, rely exclusively on diagnostic codes (they replaced my TCM for $300, but it solved nothing), and they have no built up store of knowledge/experience regarding GM models (especially one like the Cobalt that has been around since '05). At $79/hr, I can't afford to pay for guesses, or install $300 parts to see if that fixes it. Surely by now they know the difference in symptoms between a bad BCM, TCM, power steering motor, or undiagnosed short. Keep me posted - I still need to fix mine (the summer heat makes it worse), and I need to know more than the mechanic.

If your dealer is having a hard time fixing the issue, I would recommend asking him to involve Technical Assistance. Please let me know how things go. Have a great weekend!

I'm happy for you if that fixes everything, but $1,200 for two computer chips is a bit pricey. It's not like they have to build the parts special. Those two pieces and software are 5% of the cost of a new car. It just doesn't make sense. You can get a grease monket to do a trans for that price. And worse, it's not like installing these parts and programming them requires any skill. To me this is just a hidden GM money maker.

i wish my car has only had one problem. everytime i turn around its something from the key being stuck in the ignition and the locks going up and down by themself to now the check engine light is on and now the car wont start.!!! dont have the money to get it fixed or even towed to get a scan done on it. just wait till your about to pay it off and it'll die on you like it died on me !

I wish Chevy would just give us a different car. I don't even care if it's a used car. This car is a piece of junk and the transmission problem they can't find is still happening between 35-40 mph.
