2021 Chevrolet Blazer

I was driving at approx 45 mph when my car lost all ability to accelerate and shut down in the street. Flashing check engine light and esc warning on the screen. It would try to start but wouldn't. I had it towed to a mechanic who diagnosed and informed me that it is the Fuel pump power control module. Upon review he I formed me that there was a recall posted in September 2025 for 2021 Blazer on this exact issue. My car has now been unusable for a week as my mechanic recommends it be repaired via recall at dealership.

I PURCHASED MY 21 CHEVY BLAZER IN 2024 AND HAD A FEW PROBLEMS WITH A TRANSMISSION PROBLEM. THE VEHICLE WOULD STOP AND JERK WHENEVER I DROVE IT. I TOOK IT TO THE DEALER A FEW TIMES FOR REPAIR. THEY CLAIMED TO HAVE FIXED THE PROBLEM, BUT IT STARTED AGAIN SEVERAL MONTHS LATER. THE VEHICLE HAS APPROX 82,000 MILES ON IT. I HEARD THAT THERE WERE SOME RECALLS ON THESE VEHICLES, BUT NOT SURE IF MINE IS ONE OF THEM. I FEEL THERE ARE OTHER VEHICLE LIKE MINE THAT HAVE THE SAME PROBLEM.

In March after a short drive, 24 miles, the car temp was pegged at Cold. After turning off the car, the fan continued to run several minutes. After a quick internet search several posts commented on a similar issue with their vehicle. Two potential issues were identified - thermostat failure or programming issue. With less than 40,000 miles on the car, I purchased a diagnostic tool. Running the tool program two errors were identified. After resetting the sensors, the problem went away. In September, yesterday and today the problem occurred again - and the error reset fixes the issue. I believe Chevy needs to fix the issue with a recall to either update programming or replace the thermostat. [Several posts state the thermostat replacement didn't fix the issue and is very expensive.]

Request for Recall Review – 2021 Chevrolet Blazer Steering Assist and Cooling Fan Issue Hello, I am writing to report a recurring issue with my 2021 Chevrolet Blazer and to request that this concern be reviewed for possible recall or warranty coverage. The vehicle frequently displays an “Action Required: Steering Assist is Reduced. Drive with Care” message while driving. Additionally, after shutting off the vehicle, the engine cooling fan continues to run for up to 20 minutes, as if the vehicle is overheating. This issue has occurred multiple times and raises concerns about potential problems with the steering assist system, cooling system, or electrical sensors. I’ve noticed that other Blazer owners have reported similar experiences online, which suggests this could be a broader issue. Could you please confirm whether there are any existing recalls, technical service bulletins (TSBs), or warranty programs addressing this condition? I would also appreciate guidance on the next steps for inspection or documentation. Vehicle Information: Year/Model: 2021 Chevrolet Blazer
