NHTSA Complaint about POWER TRAIN filed April 17, 2019
NHTSA complaint #1558694 (ODI reference 11196908) concerns a 2008 MERCURY MOUNTAINEER and was filed on April 17, 2019. The owner reports the failure occurred on March 4, 2019. The vehicle had 129,000 miles on the odometer at the time of the incident. The report was geocoded to Maryland based on the filer's self-reported location. The affected component is categorized as power train, 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 MERCURY MOUNTAINEER cohort independently describe similar power train 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 2008 MERCURY MOUNTAINEER shows the complete component-level complaint distribution alongside any active investigations or recalls.
