Had my 2001 Prius for 14
Had my 2001 Prius for 14 years and 180,000 miles and the battery pack had to be replaced at around 110k miles. Now driving a 2016 Sonata PHEV and Hyundai is in the process of replacing the pack after only 82,000. I love seeing stories of battery packs lasting forever but unfortunately that hasn't been my experience.
