NHTSA Complaint about FORWARD COLLISION AVOIDANCE: WARNINGS filed August 26, 2025
NHTSA complaint #2124254 (ODI reference 11683187) concerns a 2025 GMC SIERRA 1500 and was filed on August 26, 2025. The owner reports the failure occurred on May 10, 2025. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as forward collision avoidance: warnings, 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 GMC SIERRA 1500 cohort independently describe similar forward collision avoidance: warnings 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 GMC SIERRA 1500 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
On August 15th, 2025, I brought my new 2025 GMC Sierra 1500 Denali to Bill Cramer GM Dealership, 2251 W 23rd St, Panama City, FL 32405, due to a complete loss of audio in the cabin. This affected the turn signals, radio, and critical safety alerts, including collision warnings and seatbelt reminders. Given the vehicle's high cost and its status as a new premium model, this malfunction was both disappointing and alarming, particularly due to its implications for safety. This occurs about every third time I drive the vehicle. The dealership retained my vehicle for over a week to diagnose and address the issue. I received an email stating that the service was complete and the truck was ready for pickup. However, upon arrival, a service technician informed me that they could not identify the cause of the audio failure and, consequently, no repairs were made. I was told the dealership would continue consulting with General Motors' corporate engineers to determine the cause and solution.
