I just got my Ioniq 6 SE back after a 3-month absence due to an ICCU backorder. There seems to be a possible error in the calculated mileage after a full charge... Previously, in eco mode, I recall seeing over 290 miles per 80% charge. However, after I got it back the display now shows 288 miles of 100%.

It was left uncharged while at the dealership for almost 3 months. They also replaced the 12v battery due to a complete power outage during the time it was with them.

Have you guys encountered with the calculated mileage after something like this?
 
They've likely just adjusted the numbers the car uses to estimate range. You know, based on your recent driving habits and weather conditions. Honestly, I'd say don't sweat the range I guess and focus on monitoring the battery percentage instead.

I can relate to your situation, when I got my Ioniq back after some work, I noticed the estimated range was off too. It showed lower mileage than I remembered, and I was worried something might be wrong. After a few charge cycles and some driving, the estimate improved, so maybe it just needed time to recalibrate. It’s frustrating, but hopefully, your mileage will get back to what you expect.
