Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM:12V/24V/48V BATTERY filed September 17, 2025
NHTSA complaint #2131406 (ODI reference 11687980) concerns a 2021 TESLA MODEL Y and was filed on September 17, 2025. The owner reports the failure occurred on August 4, 2024. The report was geocoded to New Jersey based on the filer's self-reported location. The affected component is categorized as electrical system:12v/24v/48v battery, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same TESLA MODEL Y cohort independently describe similar electrical system:12v/24v/48v battery failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2021 TESLA MODEL Y shows the complete component-level complaint distribution alongside any active investigations or recalls.

On [XXX], the car was parked at my regular parking garage. The valet entered to the car to bring it down for pick up. After he entered, the power on the vehicle went out and the door would not open. He did not know about the manual door release. I walked up to see what the delay was and found him locked inside. The car was parked on an upper floor and the it was over 100 degrees in the car. We contacted 911 but eventually found the door release. Tesla was notified and towed the car several hours later. They jumped the car to get it open. It seems that the 12V battery had died without warning.
