2025 HYUNDAI TUCSON — Complaint #2177370
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: BLIND SPOT DETECTION filed February 16, 2026
NHTSA complaint #2177370 (ODI reference 11718346) concerns a 2025 HYUNDAI TUCSON and was filed on February 16, 2026. The owner reports the failure occurred on November 3, 2025. The report was geocoded to Connecticut based on the filer's self-reported location. The affected component is categorized as lane departure: blind spot detection, 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 lane departure: blind spot detection 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 2025 HYUNDAI TUCSON shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
Blindspot detection did not pick up car on my right side two times. Front collision warning is effected by the angle of the sun at certain times of the day. Dashboard dims randomly. Could be for a minute or much longer. Could dim on and off, or stay dimmed for over twenty minutes. Brought the car in twice for this problem. Claimed nothing found and tech reset the codes. Bought it in two weeks later, stating problem not fixed. Told them to check connection, suggested they might want to replace the cables, and its a known problem. Again, reset the codes. Only this time they fiddled with the dimmer control on the console and I can no longer adjust the setting.
