2020 TOYOTA HIGHLANDER — Complaint #1946641
Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM:STARTER ASSEMBLY:RELAY filed November 30, 2023
NHTSA complaint #1946641 (ODI reference 11557585) concerns a 2020 TOYOTA HIGHLANDER and was filed on November 30, 2023. The owner reports the failure occurred on October 30, 2023. The vehicle had 57,000 miles on the odometer at the time of the incident. The report was geocoded to Georgia based on the filer's self-reported location. The affected component is categorized as electrical system:starter assembly:relay, 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 TOYOTA HIGHLANDER cohort independently describe similar electrical system:starter assembly:relay 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 2020 TOYOTA HIGHLANDER shows the complete component-level complaint distribution alongside any active investigations or recalls.
