2021 Chevrolet Blazer

The vehicle showed an error on the dash which stated "Action Required Steering Assist is Reduced Drive with Care" I tool the vehicle to the dealer I purchased it from McClusky Chevy at Kings Auto Mall in Mason Ohio. They informed me that the error code is C0460:58 and GM has a service bulletin 20-NA-215 which advises to replace the Steering Gear due to internal component interference. No one explained to me that this could cause catastrophic failure and lead to a crash before I left the dealership. They could not replace it as they said they do not have the part and it is on national backorder. Additionally they told me the repair would cost me $3,400. The vehicle has 42k miles on it and this repair is not under warranty as the warranty that would have covered it expired in March of 2026. I have taken the vehicle to a different GM dealer - Tom Gill GMC in Fairfield Ohio - they are waiting on the part and I have a case opened with GM regarding the costs. You would think that if there is a risk of a catastrophic failure which could cause harm to my self or someone else - the dealer would have an obligation to tell me so before i drive off. If not legally, certainly morally.

In September 2023, when getting my vehicle serviced for a routine oil change, I was told there was a leak in my radiator. They replaced the entire thing under warranty. On November 15th, 2025, while driving on the highway heading home from out of town with my children, an error flashed up saying “steering assist is reduced – drive with care” Upon arriving home, the fan on my car was running on high for a solid 10 minutes after turning the car off. No recall but Special Coverage N252508350 covers the thermostat replacement. Upon inspection by a mechanic, I was informed that the radiator is also leaking again in the exact same spot as it was previously. It should be noted I have never seen leaking fluid in my garage/driveway. I’ve driven less than 10,000 miles since the radiator was replaced previously. If there is a known problem with the coolant system which can cause overheating and steering assist issues, why isn't the faulty radiator and thermostat recalled. The radiator is cased in plastic to aluminum. Plastic can easily catch fire if a car overheats. The casing also prevents an owner from even knowing if there is a leak since the plastic is catching leaks - the mechanic informed me that's why I didn't know about both times it leaked. This is a 4yr old car with 46k miles, twice replaced radiator and thermostat. A recall should be issued since both problems could potentially cause a fire from an overheated engine & loss of steering assist while driving. A google search quickly showed me thousands of other Chevy Blazers from 2019-2021 with reoccurring thermostat and radiator issues. I feel unsafe driving in my vehicle but still owe too much to even trade it in for something else. I've owned dozens of vehicles in my lifetime, used and new and keep them 8-10yrs and have never had to replace a thermostat and radiator. This vehicle is dangerous due to GM/Chevy's cheap radiator model and thermostat which could overheat and catch fire

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

Midway home I got a message on my dashboard “steering assist reduced - drive with care”, but my power steering was still functional. I parked my car in the driveway, shut it off, and the cooling fans started blowing excessively. This continued for 5-ish minutes before shutting off on its own. Then I noticed that the engine temp gauge wasn’t working. Unsure if this is a problem with the thermometer or the sensor currently.

This is re: dash warning that came on saying "Action Required, Steering Assist is Reduced, Drive with Care" on 2021 Chevy Blazer, 28.800 miles. First happened 1/15/25 & each time car is started it is on now, plus the Check Engine light is on now. The fan of the motor runs for 5-10 minutes once car is shut off also. I have read of the power steering locking totally up on other Blazers that this has happened on, making this a very big danger and risky. I am not sure if it is power steering, electrical, or engine issue, but believe with so many reports out there and it causing a danger to people driving, GM/Chevrolet should put a recall on this and look at these before people are killed (if not already due to this). I am taking mine to Chevy dealer to have it looked at, but many people may not have that option.

While driving previous year 2024 the steering wheel became stiff and hard to turn. I was going around 60MPH and the Reduce Steering Drive with caution appear. Took it to the nearest Autzone no codes. We removed battery for 30 min and the steering wheel worked. Again changed my battery and the steering wheel will not turn. Had to disconnect for a day and the steering wheel worked. Fast forward 2025 Jan 14th driving down highway 360 going 60MPH my steering wheel message reappear. Called a dealer service they say they don't know. We had to tow it back to the house after work my OBD reader did not have any codes. Is a dangerous issue that needs to be recalled. I could of cause and accident.
