Recently I had multiple ppr issues that ended up in having the dealership replace my high voltage battery pack. Well, after a month of waiting for it to get replaced and driving it for 2 days with the new pack I noticed that I'm only using 8kwh. Is that normal on a new pack and will increase over time or is it possible that the dealer lied and simply reduced the usable kwh in order to get rid of the ppr notifications?

How many kWh were you getting before you starting having the ppr issues? That should be the baseline to compare the new pack to. The warranty says a replacement pack will give an equivalent kWh capacity to a normal pack, accounting for the age of the car.

But I doubt if the dealer did any kind of test to measure the kWh capacity of your original battery before replacing it. It might be a good idea to periodically run the pack down to zero see how many kWh it says it used. If this was done at least once a month and the results were recorded (maybe photos of the "kWh used" on the display), you would have a good case to make if the new battery did not provide the same capacity.

For the last 99k miles I have been getting between 10kwh to 10.6kwh so I have lost 20% of the usable battery. Maybe it has to run a few cycles before measuring voltage correctly?

Well, good news. I just arrived home and noticed that my 2012 used 11.3kwh! I suppose the kwh meter is just averaging out but I am also hoping of the possibility that I received a 2014/15 Volt battery as Ive never seen over 10.6. Fingers crossed

Was the whole pack replaced or just a section?

Either way, my kWh usage was all over the map when my 2 sections of my '13s pack was replaced. It eventually leveled out, but took a few weeks of mostly daily full charges/discharges. Enjoy the ride, I got some of the highest EV miles ever (like 52!) on the "new" pack as it figured out the top and bottom SOCs. Unfortunately, it didn't last but I still ended up getting a mile or two extra with the new pack.

It was a full pack. Ya I figured the 11kwh prob wouldnt last.
