What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2020 Zero Sr/F, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
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.
Too few reports in this category for a page of its own — they appear in the full complaint list.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
