Wondering if anyone else has experience with this. My battery 'failed' last August and would only give me 35km of driving range. The dealership thought it would need a new battery but then a GM tech advisor told him how to 're-program' the battery. Since then it has been working fine and I am back up running in the 65km range during the summer months. Could anybody shed any light on this?

 

I wonder how did that go with you , I'm afraid I have a similar issue with my chevy
