Well I got the call back and they are covering 100% for me. The only thing I can see that I have done differently from other people on here is I have always done the battery check for the last 5 years within days of my anniversary date. I have also gotten all the recommended maintenance done on schedule (brake fluid flushes, cabin filter changes). I also even just have the reduction gear oil changed this March as I felt 100,000 miles was to far to go on the original oil. The other thing I did do was go to the dealership and had them run the battery report, and ran the battery claim through them before calling the EV help line. 3 weeks later though they have come back with the 100% offer, and the battery is currently sitting at the dealership according to my service advisor. They are just waiting on the rest of the adapter parts to come in. I am also doing the TCU upgrade, changing the 12V battery that is 5.5 years old since they told me the car had a bunch of brake ghost codes when they just did the battery check, and getting the rear door gas struts replaced before it gets to cold and the door starts dropping on my head again. As soon as I have the car back and a total in hand I will let you guys know the overall cost though and if I wind up paying for the adapters/labor.
EDIT: I guess other important information is that my car was at almost 57,000 miles, but my 5yr time frame was up on March 23rd which was the cars in service date. So that puts the car almost 6 months beyond the warranty time frame. Either way I found the people to be super nice on the phone. When I originally called I just asked for the 80/20 deal that I told them I had seen other people getting online as I had saved money for that since I knew the 4th bar would be dropping off soon. Me, the dealer, and the EV hotline rep was shocked as even he said it had been awhile since he saw them cover 100%. So I have no tips for you guys as I am probably the worst negotiator, and I had just asked for the 80% from the get go.
