Known issues

Medium

Cybertruck drive-inverter recall (NHTSA 24V-832) addressed a fault that could cause a loss of drive power. Tesla replaced affected inverter assemblies. Pack chemistry was not implicated.

NHTSA recall

Medium

2025 Model 3 / 2026 Model Y battery-pack contactor fuse recall (NHTSA 25V-690) addresses a fuse that could fail to open under fault conditions. Free replacement at dealer.

NHTSA recall

Low

Dry-electrode cell coating has been the bottleneck on 4680 production volume. Wet-process cells substituted on early Cybertruck packs — same chemistry, different process.

News

Low

Structural pack design means battery replacement is not a service-bay job. Early failures have required full pack swaps; service capacity for 4680 work is concentrated at Fremont and Austin.

Owner-fleet data

How this pack ages (industry context)

Industry fleet aggregates: 2.3% average annual capacity loss across 22,700 EVs / 21 models (Geotab, 2026), and 95% range retention at 5 years on average across 30,000+ vehicles (Recurrent, 2026).

OEM warranty floor on this pack: 8 yr / 150k mi to 70% capacity.

Public per-pack degradation curves are not available for most models. Individual results vary materially with climate, charging behavior, and DC fast-charge frequency.
