Known issues

Low

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

Low

Cybertruck has had multiple recall campaigns in its first year (accelerator pedal, windshield wiper motor, exterior trim) but none affecting the HV pack itself as of 2025.

Low

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

Low

Cybertruck range tested below EPA estimates in cold weather and at highway speeds; this is range-prediction calibration, not pack defect.

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.

Battery-Related NHTSA Recalls

Recalls affecting battery, charging, electric propulsion, or thermal-event systems on vehicles using this pack. Recalls are deduplicated across model variants; affected vehicles are listed for each campaign.

25V690000 10/10/2025 ELECTRICAL SYSTEM:PROPULSION SYSTEM:FUSES, RELAYS, CONTACTS, AND SHUNTS

Tesla, Inc. (Tesla) is recalling certain 2025 Model 3 and 2026 Model Y vehicles. The battery pack contactors may fail, causing a loss of drive power.

Consequence: A loss of drive power can increase the risk of a crash.

Affects: Tesla Model Y 2025-2026

24V832000 05/11/2024 ELECTRICAL SYSTEM:PROPULSION SYSTEM:INVERTER

Tesla, Inc. (Tesla) is recalling certain 2024 Cybertruck vehicles. A fault in the drive inverter may cause a loss of drive power to the wheels.

Consequence: A loss of drive power can increase the risk of a crash.

Affects: Tesla Cybertruck 2024-2025
