NHTSA Complaint #11587697 — 2020 ZERO SR/F

My 2020 Zero SR/F is BEV motorcycle. I purchased it new in July 2020 and by February 2023 the total range on a full battery charge was approximately 25% of the original specifications. Where I would get between 100 and 160 miles on a full charge depending on speed in 2020, in February 2023 I was consistently getting 30 miles on a full charge at 55mph. The motorcycle was also recharging on level 1 charging at 11A from 10% to 100% in less than an hour, which should not be possible normally using a 5-15 household outlet to charge the 14.4kWh battery. The manufacturer warrantied battery capacity to be ≥ 80% of original capacity for 5 years/200,000miles. The manufacturer replaced the original 14.4kWh battery pack in October 2023 with ~2200 miles on the odometer with a new chemistry battery pack. This followed range tests by two authorized dealers and an engineer from the manufacturer. The safety risk was being stranded by the motorcycle because the battery pack was failing prematurely. I have had no range/capacity issues with the replacement battery pack that has a different capacity than the original battery pack.
