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

The contact owns a 2021 Chevrolet Blazer. The contact stated that while her husband was driving 60 MPH, the "Service Engine Soon" message was displayed. The contact's husband pulled over to the side of the road. The contact's husband used his personal FIXD machine to diagnose the vehicle. The contact’s husband retrieved DTC: P023F (Powertrain Control Module Detected a problem in the Electrical Pathway supplying power to the Fuel Pump). The vehicle was towed to an independent mechanic who diagnosed the vehicle and determined that the fuel pump had failed. The vehicle was then towed to the dealer. The vehicle has not been diagnosed. The contact related the failure to Manufacturer's Recall Number: N252516900. However, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was 90,493.

Steering assist reduced warning came on with engine light. When car turned off , radiator fan continued running for a few minutes before turning off. AC would also not work during this time. Issue has been intermittent. Was told the thermostat was getting stuck open and needs replaced.

Brake booster failed after 50k miles needing repair. Brake became very still, prolonging the time it takes to stop the vehicle

Was informed at today's oil change that my radiator is leaking and it's something that they are seeing a bunch.

my vehicle is roughly 40k miles. The temp gauge was stuck on C the cooling fan was running continuously even when the car was off and the checked engine appeared. The mechanic at the dealership said the thermostat is stuck in open position causing the computer not to know if the engine is cooling properly. For a vehicle less then 5 years old with upkept maintenance and doing a bit of research... This is a common occurrence in Chevy vehicles. Therefore, the manufacturer needs to look into recalling this issue costing people thousands of dollars. This was my first Chevy and probably my last.

Auto braking system went off when I was at stop light & began to move forward (was 2nd in line of cars) and I accelerated. On the roadway, there are construction 'steel plates' laying on the ground in the area that all cars must drive over (I have driven over them in my same Blazer before) because we have no choice. One I pressed on gas & began moving over those plates, the Blazer stopped itself VERY abruptly & jerked my head forward & dash said I had to press on brake let off or something in order to move again - it was all very fast & I had a line of traffic behind me at 5:15 pm on a Friday (9/5/25). I'm very luck I did not get hit from behind & car behind me paid attention! That is the 3rd time my car has stopped suddenly; 2 times before it was when going up my very steep driveway so I had no one behind me & I wasn't as shook up - Chevy needs to REALLY look at this! It is a hazzard!!

I was driving down 776 (a busy highway)Blazer completely shut off, so scary almost got hit by a semi, I don’t know how he managed to get around me , I jumped out of car! Sure thought it was my day to die! Called police for help! Had it towed home then to garage , was told it was the electrical fuel modular! Haven’t slept right in 3 days ! I’m still so shaken up!

The temperature gauge or thermostat has been replaced 3 times and continues to fail
