2017 HONDA ACCORD — Complaint #2156163
Open-data reference.
NHTSA Complaint about FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING filed December 10, 2025
NHTSA complaint #2156163 (ODI reference 11704299) concerns a 2017 HONDA ACCORD and was filed on December 10, 2025. The owner reports the failure occurred on December 10, 2025. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as forward collision avoidance: automatic emergency braking, 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 HONDA ACCORD cohort independently describe similar forward collision avoidance: automatic emergency braking 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 2017 HONDA ACCORD shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
Vehicle: 2017 Honda Accord EX Mileage at incident: Approx 30,000 Date of incident: Dec 10, 2025 Description of problem: While my daughter was driving our 2017 Honda Accord EX, the Collision Mitigation Braking System (CMBS) suddenly activated without warning. The car slammed on the brakes even though there was no obstacle in front of her. This caused the vehicle to skid, but fortunately there was no collision or injury. There were no diagnostic codes found when inspected by an independent auto shop. The shop advised us to temporarily disable the CMBS system. This appears to be part of the ongoing issue of phantom braking in Honda vehicles, which has been reported by many owners and is currently under NHTSA investigation. I am concerned about the safety risk, especially since my daughter drives this car regularly. Safety concern: Unexpected braking at highway or city speeds could easily cause a rear-end collision or loss of control. I request that NHTSA investigate this incident
