2016 HYUNDAI TUCSON — Complaint #1826050
Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR filed July 15, 2022
NHTSA complaint #1826050 (ODI reference 11474156) concerns a 2016 HYUNDAI TUCSON and was filed on July 15, 2022. The owner reports the failure occurred on September 15, 2020. The vehicle had 140,963 miles on the odometer at the time of the incident. The report was geocoded to Louisiana based on the filer's self-reported location. The affected component is categorized as engine and engine cooling:exhaust system:emission control:catalytic convertor, 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 engine and engine cooling:exhaust system:emission control:catalytic convertor 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 2016 HYUNDAI TUCSON shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at various speeds, the vehicle would stall upon depression of the accelerator pedal without warning. The contact initially took the vehicle to an independent mechanic where the catalytic converter, spark plugs, and coil packs were replaced. Eight months later, the failure returned and the same mechanic informed her that the evaporated oil had melted the catalytic converter and referred her to the dealer for assistance. The vehicle was then taken to the dealer on three separate occasions and each time the catalytic converter was replaced; however, despite the numerous replacements, the failure persisted. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was 140,963.
