I checked the wires and everything seems to be fine so i made an appointment and now it comes on more frequently , sometimes every 5 minutes
I have an appointment at the dealership tomorrow, but i can certainly give you the last 8 digits of my vin (77328351)
I looked into your Cobalt's information, and am not seeing any open recalls on your vehicle at this time.
For your information, here are the warranty parameters (expiration is by date or mileage, whichever comes first):
Emission Select Component until 10/04/2015 or 130,150 KM
Corrosion Limited Warranty until 10/04/2013 or 160,150 KM
New Vehicle Limited Warranty until 10/04/2010 or 60,150 KM (Expired)
Powertrain Limited Warranty until 10/04/2012 or 160,150 KM
If you should like Customer Assistance at any point after your visit to the dealership, unfortunately I cannot set anything up on my end (as I am a US Customer Service Rep). However, you can get in touch with GM of Canada at 800-263-3777 (Hours: M-F 7:30am - 11:30pm, Sat 7:30am - 6:00 EST).
All the best, and still look forward to an update!
