I received a check engine light which I took to bell tire for diagnosis. Here is there diagnosis comments: the p01f0 code on a 2020 chevy Blazer means the engine coolant temperature is below the normal operating range, often due to a stuck-open thermostat (or both thermostats in models with dual units), a faulty engine coolant temperature (ect) sensor, or low coolant, leading to poor fuel economy and potential wear; fixing it usually involves replacing the thermostat(s) or sensor after checking coolant levels and wiring. After that I took the vehicle to gm dealership. Even though this is a know issue with many vehicles from same year, I was told that my VIN is not part of recall and dealership ended up charging me 600+ to fix the issue. I am reaching out to seek help as I had exact same problem but gm is not covering the repairs because my VIN is not in the recall. How is that possible?.
To whom it may concern, I am writing to formally file a complaint regarding ongoing and persistent issues with my 2020 Chevrolet Blazer. The vehicle has exhibited repeated problems that I believe may indicate a broader safety or mechanical defect, and I am requesting that the NHTSA investigate these concerns further. Since purchasing the vehicle, I have experienced the check engine light turning on and off repeatedly, without consistent resolution. The following issues have occurred over time, all seemingly related to the engine or control systems: engine cooling system failure: the first major issue involved the engine cooling system. This caused the vehicle to overheat and required service. I was concerned about the potential for engine damage or fire risk due to excessive heat. Variable valve timing (vvt) system malfunction: shortly after the cooling system issue, the vehicle began experiencing problems with the variable valve timing system. This not only affected performance and fuel efficiency but also caused the check engine light to illuminate again. Steering control assist sensor warnings: most recently, the steering control assist sensor has started to malfunction, with warnings frequently popping up on the dashboard. This has impacted steering feel and raises serious safety concerns. Despite multiple service appointments and repairs, these problems persist or reappear. This cycle of temporary fixes without a lasting resolution is both frustrating and concerning from a safety standpoint. I am requesting that the NHTSA look into whether these recurring engine and control system issues are part of a known defect or recall-worthy problem affecting the 2020 chevy Blazer. Thank you for your attention to this matter.
6/12/2024 in damon parking lot in rochester mn. Going less than 10 miles an hr- cars in front of me and behind me looking for a parking spot. Stop and go at times. Went to turn corner to go from one level to the next and my Blazer took off "like a bullet". No control over accelerated speed- hit outer cement wall and slammed into 2 parked empty suvs. Could not go any farther. The 2 suvs slammed into cement wall in front of them. Injuries to both my passenger and myself. I have no idea what happened - it was so fast- I do know I had no control over accelerated rate causing accident. My 2020 chevy Blazer was totaled- it was inspected by american national insurance CO. Absolutely no warnings. Police report did not include any witness. Blazer is in the hands of the insurance CO. Chevy Blazer took off like a bullet - could not stop it!!police report 24026393 rochester police dept unable to upload . Checked no police report below so I could continue report.
