Chevrolet Blazer Reliability by Year
Chevrolet Blazer owners report a stuck "Shift to Park" message and sticking thermostats most. Here is what to check and which model year to buy.
Chevrolet Blazer Reliability Overview
Reliability is good for a used midsize SUV and above average among SUVs. Favor the 2022 and skip the 2019 and 2024. The two problems that matter most are a "Shift to Park" message that stays on with the shifter in Park, and a sticking thermostat that brings a P0128 code, no A/C, and reduced steering assist. Estimated repair cost is $521 a year.
Current generation: 4th gen (2023–2023).
Best & Worst Chevrolet Blazer Years
Best Chevrolet Blazer Years to Buy
Based on reliability index scoreThe 2022 has far fewer owner complaints per vehicle sold than the 2019 or 2024, and only one recall on record. It is not perfect. Owners report instrument cluster blackouts and some transmission failures. Still, it avoids the repeated Shift to Park fault of the 2019 and the braking complaints of the 2024.
Chevrolet Blazer Years to Avoid
A "Shift to Park" message appears with the shifter already in Park, and the car will not shut off, lock, or stop chiming. Dealers usually replace the shifter assembly, and some owners see the fault return within two months. A sticking thermostat also shows up, with a P0128 code, no A/C, and repair bills near $1000.
