I just bought a 2014 volt with one year left on the warranty. The dealer told me and I have in writing that the warranty is good from the day first in service, in this case Sept 2014 till Sept 2017. I have the full warranty till then, not prorated in any way.In Canada, a new car warranty is reduced 1 month for each month the vehicle is unsold after the model year expires. A 2013 sold in March of 2014 only has 33 months warranty on it. Typically, these cars are heavily discounted as they are considered a year old even though sold as new.
I had this situation on a Ford that I purchased. I was told up front though that this would be the case. Is it right? Doesn't seem like it is right but it appears that is the case.
