When I purchased my left over new 2014 ELR last fall from an out-of-state dealer I was told the first oil change/maintenance would be at "no cost".
I logged into the local Certified Cadillac ELR dealership's website to make an appointment providing my VIN, and their web site states I have to pay $59 +tax. So I emailed my ELR (Volt) advisor who stated that; "GM does provide new vehicle purchases with a complimentary 2 year/24,000 mile Maintenance Plan. If you bought this vehicle outside those parameters, you may be responsible for the cost of the oil change/maintenance." Wow, Better think again!
On Edmunds.com (09/03/15) this is what I read; "Cadillac gets GM's best coverage. The Premium Care Maintenance program debuted on the Cadillac CTS Coupe, and is now standard on all new models. This program covers the car for four years or 50,000 miles, whichever comes first. Cadillac doesn't specify how many services will be covered, but a safe assumption would be that owners will get at least one scheduled maintenance per year". I'm not so sure?
FYI: My 2013 Volt's 1st oil change was @ No Charge. So I guess GM changed the rules on freebies again?
Did anyone else that owns an ELR have to pay for their 1st oil change?
