Summary Verdict
The 2021 Chevrolet Blazer generally demonstrates good reliability across its powertrain options. The 2.5L, 2.0L Turbo, and 3.6L engines have not shown significant widespread issues. The primary concern noted is with the 9-speed automatic transmission, which has seen some reports of rough shifting or hesitation, often addressable with software updates but occasionally requiring more involved repairs. Electrical systems, particularly the infotainment screen and battery, have had isolated incidents of freezing or premature drain, usually resolved by software or component replacement. Overall, the Blazer is a solid choice, with most potential issues being manageable and not indicative of systemic design flaws.
