They’re discussed a lot because Technical Service Bulletins (TSBs) from Chevrolet and data from repair shops highlight them. This makes them key topics for anyone thinking about buying or who owns one.
Loss of Power
Many drivers have faced a big problem: losing power. The 2020 Chevy Blazer sometimes loses engine power without warning, especially when speeding up. This makes it hard to keep a steady speed. Reports say this often comes from bad throttle bodies and fuel injectors getting clogged.

Engine Knocking
Engine knocking is another big issue, with many service reports and TSBs mentioning it. It’s a metallic “ping” sound that suggests something is wrong in the engine’s combustion process. It happens when the car is moving or just idling.
This knocking often comes from using gas with too low octane or from carbon building up in the engine. Repair shop data shows many knocking problems are fixed by changing spark plugs and ignition coils. This helps the engine start better.
| Issue | Common Cause | Typical Repair |
|---|---|---|
| Loss of Power | Faulty Throttle Bodies, Clogged Fuel Injectors | Throttle Body and Fuel Injector Replacement |
| Engine Knocking | Low-Octane Fuel, Carbon Buildup | Spark Plugs and Ignition Coils Replacement |
