2007 Cobalt LT Car Wont Shut Off
Hey guys i'm having a really weird problem with my cobalt LT 2007. There seems to be two common problems that occur each day.
1st: when im driving my car, all of a sudden all the odometers drop (gas, rpm and speed) and the emergency break light comes up (red ! with the circle around it) and seems to be in some sort of lock mode as when I stop and put it in park and turn the key off and pull the key out the car still runs and does not allow me to turn it off. Also when I try to put the key back in and turn it on it does nothing and will not let me change gears it just stays locked with the emerge break light on even when the emergency break is not on. The first time it happened the car ran for 10 min and shut off but last night it took 1 hr so I thought it had something to do with the factory starter that came with the car however it does not seem to think its in automatic start mode, rather than theft mode but the yellow antitheft lock is not on. In order for me to turn my car off I pull the start relay out and then have to turn the battery off as the lights remain on as well as the radio windows up/down and interior light and dash light. The only one that doesn't seem to work is the unlock/ lock inside and on my key itself. It always seems to "reset" itself and allow me to start it back up again and use the unlock/lock from the key but it makes absolutely no sense and has been doing it for a week straight. Last note, the km display just shows dotted lines that go across the display and doesn't show me how many km's it is (ONLY WHEN IN THIS LOCK MODE)
2nd: when i turn it off and lock it with my key I can come back 15 min later to unlock it but it does nothing. I then have to manually unlock with the key and when I try to turn on the car ... nothing. just shows the engine light and that emergency break light with the dotted lines across the km display. I had to walk away from the car for 15 min the first time and came back and it "reset" the longest it has taken is an hour and a half and that time i disengaged the battery to do so.
I'm really stumped as to what to do, i brought it to GM but they told me they wouldn't know until it acted up infront of them. I left it with them for two days and it didnt act up and as soon as I took it back for the weekend it kept doing one of these two problems. Ive looked up similar problems but it seems as if people having the "passlock" problem the yellow theft lock light flashes on their dash however that is not the case for me.
If anyone has had a similar problem like this one I would greatly appreciate some advice or even if you think you can direct me towards a symptom that may be affecting my car. It's very confusing and I have no clue why it's doing this.
p.s my friend suggested that maybe the computer for the anti theft lock system needs to be changed? I feel like it does have something to do with thinking its in theft mode. also have there been any recalls on something like this that anyone has heard of? Thanks again any suggestions would be greatly appreciated!
