Alright so i bought this cobalt ss/sc two months ago. it has ran fine up untill about 4 weeks ago. i was jus driving and the information display came up power steering and my speedo dropped to zero... then it came back. i thought o well its all good. well it happens quite often at this point like everyday. i have had it into a gm dealership and they couldnt come up with the problem or a solution... and then they called GM on it and they were not able to help....

Any insight or knowledge of this problem and where i can find out a solution to the problem... cuz everyone GM based i have spoke to has not heard of this problem. i have done nothing to the car, it came from the dealership with stage 2, GMPP exhaust, the K&N typhoon intake...

Any help is greatly appreciated...

? Good luck...

 

thanks this is a pain in the a@@.. im very unhappy that i was sold this car and it was GM Certified, but luckily i bought a platinum warranty...

 

hope you get it worked out...not sure about that one.

 

thanks man me two, ive even gotten a ticket cuz my speedo messes up... like it'll jus drop like 20 moh and then kick back up and drop again and stuff

 

Have them check the ground, would be possible if its not making a good connection. Its behind one of the headlights, don't remember if its left or right.

 

I had a similar problem. Did you add anything electrical to it? The previous owner of my LS didn't buy power windows/doors from the dealer and got aftermarket ones. It ended up sucking too much power on startup. A buddy of mine down at the Chevy dealer popped in a relay kit and I was fine.

 

i will have them check the ground for sure thanks, and i havent done anything electrical to the car...

thanks much appreciated
