2020 Chevy Blazer LT 3.6 L V6 I'm filing this complaint regarding multiple concerning mechanical and safety related issues with my 2020 Chevy Blazer LT that I purchased brand new and currently have 54,224 miles . Without warning, My vehicle developed several problems simultaneously. The check engine light came on, The engine cooling fan started running continuously at high speed, the AC stopped blowing cold air and is warm air, the steering assist reduced came on and my chevy app notified me that I have an engine cooling system malfunction and to service now. It's showing a P0128 code when I had it checked. After doing some research, I discovered GM issued a thermostat special coverage program for certain vehicles 2021-and newer models. Mine isn't part of it because of the year and isn't covered by the power train warranty for the same reason even though they all have the same engine. I only have 54,000 miles! I'm very concerned over the steering assist being reduced! What if the steering goes out while I'm driving? I have my grandchildren all the time. I need my car! There are several other complaints on here for the same vehicle and the same problem! Why isn't the 2020 Blazer covered under this special coverage program? The dealerships all say it's a well known problem! I believe this issue deserves investigation !

My 2020 Chevrolet Blazer experienced severe mechanical problems, including stuttering, loss of power, and the engine shutting off unexpectedly while I was driving. The vehicle subsequently would not operate normally. On February 25, 2026, Rick Hendrick Chevrolet Duluth performed a diagnostic inspection and recommended nearly $20,000 in repairs, including transmission-related repairs. However, the dealership did not identify or disclose any alternator fire damage or related electrical safety concerns. In October 2026, an independent mechanic discovered significant burn damage on the alternator. The damage was visible externally, and further inspection of the alternator’s interior revealed additional evidence of burning. I believe this condition may have contributed to the vehicle’s sudden loss of power and shutdown. This presents a serious safety concern because an unexpected engine shutdown while driving can increase the risk of a collision, and an electrical failure involving burning components may present a fire hazard. The vehicle has not been driven since the dealership’s inspection. The damaged alternator has been preserved, and photographs were taken documenting its condition. The component is available for further inspection upon request. I am requesting an investigation into this alternator failure and the associated vehicle safety risks.
The thermostat is malfunctioning along with engine temperature coolant sensor. This causes the temperature gauge on the dashboard to be completely disabled and not moving off cold, it disables the air conditioner, makes the engine cooling fan to run extremely high nonstop, and places the vehicle into an unpredictable limp mode or fail safe mode. This was identified as faulty by GM and they have issued a special service bulletin that they will repair it up to a 150,000 miles or 15 years or reimburse customers up to $1200 on 2021 models. The 2020 models use the same engine and parts but they refuse to include them which is an unfair exclusion since they admitted to a faulty part. 2020 should be included with the same 150,000 miles and 15 year coverage or reimbursement.

The radiator and thermostat on my 2020 Blazer had to be replaced at less than 35,000 miles. It was out of warranty and the Chevy dealer charged me $3,500 to replace them. Internet sources state that this is a common problem with this car. I complained to Chevy corporate and they refunded $1,000. I do not feel this was a fair settlement due to the fact that it is a common problem.
