2018 GMC SIERRA 1500 — Complaint #2112939
Open-data reference.
NHTSA Complaint about EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM) filed July 22, 2025
NHTSA complaint #2112939 (ODI reference 11675477) concerns a 2018 GMC SIERRA 1500 and was filed on July 22, 2025. The owner reports the failure occurred on July 22, 2025. The report was geocoded to South Dakota based on the filer's self-reported location. The affected component is categorized as equipment:electrical:navigational system(global positioning system), 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 equipment:electrical:navigational system(global positioning system) 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 2018 GMC SIERRA 1500 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The embedded navigation system in my 2018 GMC Sierra is no longer supported. Paid map updates were available until 2023, when General Motors discontinued them without notice. This system was marketed as a core feature and provided offline GPS guidance independent of cell reception. I discovered the change while attempting to purchase an update and was told there are no remaining copies and that no further updates will ever be made. I was never notified. When I contacted support, I was transferred through six departments. One representative admitted that customers were supposed to be informed but were not. She stated they are trained to say âthereâs nothing we can doâ and acknowledged receiving hundreds of similar complaints. She also confirmed the final map update existed but was allowed to sell out. This puts safety at risk, particularly for drivers in rural areas, areas with poor cell service, or while towing. The system is not CarPlay-based and does not rely on mobile data.
