2021 CHEVROLET TRAILBLAZER — Complaint #1973557
Open-data reference.
NHTSA Complaint about Tether, Lower Anchor (on car seat or vehicle) filed March 8, 2024
NHTSA complaint #1973557 (ODI reference 11576177) concerns a 2021 CHEVROLET TRAILBLAZER and was filed on March 8, 2024. The owner reports the failure occurred on March 8, 2024. The report was geocoded to South Carolina based on the filer's self-reported location. The affected component is categorized as tether, lower anchor (on car seat or vehicle), 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 CHEVROLET TRAILBLAZER cohort independently describe similar tether, lower anchor (on car seat or vehicle) 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 2021 CHEVROLET TRAILBLAZER shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
My issue is with the vehicle's car seat latches. The latches in the Chevy Trailblazer (Manufactured) are designed in a way that is unsafe and also hard to install a car seat for children who are 2 and under or under 40 pounds. Car seat safety is important for all children as it could lead to damages of the head, neck, and or spine. I have installed 4 car seats in my vehicle (Chevy Trailblazer) with it being difficult but overcoming the problem. However, the car seat detaches itself due to the location of the latch (Vertically Slanted). After using the car seat multiple times, it cannot withstand the tension due to the location of the latch which then releases itself from the latch, potentially allowing for more problems to occur and is concerning for the safety of a child. I have, as of now, not have to deal with this problem with other manufacturers like Toyota, Kia, Tesla, Volkswagen, and Honda, where the latch is horizontal. The latch on GMs Vehicles is Vertically Slanted and locate
