2021 Chevrolet Blazer Safety Report

The 2021 Chevrolet Blazer presents a mixed safety picture, with strong crash test performance but a notable number of owner complaints, particularly concerning the engine and cooling system. NHTSA awarded the vehicle a perfect 5-star overall safety rating, including 5 stars for frontal and side crash tests, and a respectable 4 stars for rollover. This indicates robust occupant protection in various collision scenarios. However, the vehicle has accumulated 109 owner complaints, including 4 crashes, 1 fire, and 3 injuries, which is a significant number for a relatively new model year. The single recall addresses a critical seat belt attachment issue, which could compromise occupant restraint in a crash, highlighting a manufacturing defect that needed correction. Analysis of the complaint data reveals a concerning pattern related to the engine and cooling system. 'ENGINE' is the third most reported component with 10 complaints, but many 'ELECTRICAL SYSTEM' and 'FUEL/PROPULSION SYSTEM' complaints also describe engine-related symptoms like reduced power, stalling, and check engine lights. Specifically, numerous complaints detail radiator failures, coolant leaks, thermostat malfunctions, and continuous fan operation after the vehicle is off, often occurring between 30,000 and 60,000 miles. These issues can lead to unexpected breakdowns and potential engine damage. Other significant complaint areas include 'SERVICE BRAKES' (13 complaints) and 'ELECTRICAL SYSTEM' (12 complaints), with some electrical issues impacting engine function or causing warning light anomalies. The recall for seat belt attachment issues is a serious concern, as it directly impacts fundamental safety equipment. While only one recall has been issued, its nature is critical. The high number of complaints, especially those related to the engine and cooling system, suggests potential reliability issues that could lead to unexpected vehicle failures. Despite excellent crash test ratings, the recurring mechanical problems reported by owners warrant careful consideration for potential buyers, as these can lead to safety hazards if the vehicle loses power or overheats unexpectedly.

Our recommendation: While the 2021 Chevrolet Blazer offers strong crash protection, potential buyers should be aware of the recurring engine and cooling system issues reported by owners; consider a pre-purchase inspection focusing on these components and ensure all recalls, especially the seat belt recall, have been addressed.
