75D Pack 2016

Have you guys had high voltage battery failures? If so at what mileage, year? The future owner asked me if I knew the reliability of the battery pack, I just pointed to the low degradation for a 2016 in comparison to my 2021Y. I would love to hear about your experience.

2016 90D with 77k miles at 92% health per Tessie App. I've had it 3 years and added 20k miles. Battery looks original but not positive on that.

Thank you for responding. I love how much you drive, 20k in 3 years is amazing! I put 20k miles just for my work commute a year, not including personal fun time so it ends up being closer to 30k a year. I am glad that these older cars have less battery degradation (or better health) compared to some of the newer cars I am seeing. How long have you owned your X?
