2020 HYUNDAI TUCSON — Complaint #2120187
Open-data reference.
NHTSA Complaint about EXTERIOR LIGHTING:BRAKE LIGHTS:BULBS filed August 13, 2025
NHTSA complaint #2120187 (ODI reference 11680400) concerns a 2020 HYUNDAI TUCSON and was filed on August 13, 2025. The owner reports the failure occurred on June 13, 2025. The vehicle had 40,000 miles on the odometer at the time of the incident. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as exterior lighting:brake lights:bulbs, 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 HYUNDAI TUCSON cohort independently describe similar exterior lighting:brake lights:bulbs 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 HYUNDAI TUCSON shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2020 Hyundai Tucson. The contact stated that the "Check Brake Light" message was displayed on the instrument panel, and the screen indicated that the rear brake light bulb was defective. The vehicle was initially taken to an independent mechanic where the brake light bulb was replaced; however, the failure recurred. The vehicle was then taken to a dealer where the contact was informed that the brake light bulb had failed because the bulb was an aftermarket part. The contact had the brake light bulb replaced with an authorized Hyundai part; however, that part also failed soon after the bulb was replaced. The manufacturer was notified of the failure and referred the contact back to the dealer for assistance. The vehicle was taken back to the dealer but was not yet repaired. The failure mileage was approximately 40,000.
