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.

On December 4th, 2024, I was driving my Blazer up to our local Museum to grab some information. The Museum is about a mile and a half from my house. When I had left my house, the car was driving like normal. I pulled into a parking spot at the Musuem, and I went to shut the vehicle off, and I thought maybe the check engine light had come on but wasn't completely paying attention to the dash. About 10 minutes later I went to restart the vehicle to leave and I noticed the check engine light on. Since the vehicle seemed to be driving okay I thought I could make it home and check the car's computer to see what the issue was. As I was leaving the parking lot I stopped at the end of the parking lot to look before pulling out onto the road and the Blazer said shift to neutral and restart the vehicle. When I did that the vehicle would not start. It would just crank and crank and then it would finally start for a few seconds. I was going to back my vehicle up out of the road but each time I would try the car would die. I am very thankful this did not happen on the highway or even on the freeway. A friend and myself had to push my vehicle back into a parking spot. The DTC code is a P023F. When this happens, you can't technically shift the vehicle into neutral to push it out of the way because the car has to be running to shift. I was able to force it into neutral, however. I made an appointment with Awesome Chevrolet in Chehalis WA and had to have it towed to the dealer. They stated it was the fuel pump module. I had at that time 18,388 miles on the odometer. Unfortunately, I no longer feel safe with this vehicle in case it happens again. Where I am hours from home or on a 2-lane road or freeway. The fuel pump module failure appears to be a known issue with GM vehicles. The fuel pump module was replaced and was able to be replaced under warranty. I hope that it does not happen again.

The Radiator has a crack in the upper left front of the core causing the fluid to leak and lose pressure causing the engine to overheat. This is a manufacture defect that has not been addressed as of 10/16/2024. The leak was discovered by a certified GM mechanic at a dealership when doing routine maintenance and inspection. The vehicle has never had any indication or advisory light that would alert the operator. As the engine overheats it can cause many of the other components of the vehicle to disable, including but not limited to the ADAS systems as well as power steering and/or collision safety components. This is a manufactures defect with the aluminum radiator that needs to be addressed immediately. Given the information from multiple GM dealerships the amount of newer low mileage Blazers that have been confronted with this problem is unprecedented. This not only creates a danger for the passengers of the vehicle but also every other vehicle on the road.

I have a 2021 Chevy Blazer which has had to have two radiators replaced with less than 50,000 miles on the vehicle. The first time was in March of 2023. I took my vehicle in for an oil change and the technician told me the radiator was cracked and all of the coolant was drained from the vehicle. It must have just run out because I regularly check my fluids and the vehicle was not overheating prior to the appointment. The vehicle had about 32k miles on it, so the radiator was covered under warranty. Now in April of 2024 with 49k miles, I take my vehicle in for another oil change and the radiator is cracked, again, with coolant leaking. The technician told me two things that are concerning about this. 1.) This is a known issue on the Blazers that they-??ve done multiple repairs on. 2.) There is a piece of plastic under the radiator that catches the coolant when it leaks, making it hard to notice an issue because the coolant doesn-??t pool on the ground underneath. My service advisor went to bat for me against GM, who partially paid for the second radiator. This brought my installation cost to $235, even though it was no longer under warranty. Radiators cracking is a serious safety issue because if the driver doesn-??t notice the engine overheating, it could cause a vehicle fire putting the occupants and surrounding environment in danger. There are no warning lights on the vehicle to tell you if there is low coolant, other than noticing the temperature gauge when it is too late. I don-??t know if GM didn-??t install rubber bushings to absorb the impact of bumps on the road, or if it needs some rubber washers on the bolts, but something is missing. Online forums will confirm that this is an ongoing issue for owners of the Chevy Blazer

Receiving 3 different errors on dash display. 1) Action Required- No Remote Detected 2) Action Required- No Remote Detected Press Brake to Restart 3) No Remote Key Wa Detected Place Key In Transmitter Pocket Then Start Your Vehicle. All of these errors are intermittent and have appeared with using 2 different Remotes. Batteries have been replaced also. This in itself is not so much a safety hazard (annoying), but what is intermittently happening is the car shuts down while in drive and in reverse. So far it has not shut down on the freeway but has shut down while on City streets. We have taken it to 2 different GM Dealers a total of 7 times in the last 3 months(currently at the dealer now). Each time the dealer is saying they cannot duplicate the errors. We get it back and within 1 (usually the same day)day it is right back with the errors. Clearly these errors are a nuisance and dangerous if the vehicle shuts down. I have additional service documents and photos and videos but due to the maximum I can provide they are not uploaded.

The contact owns a 2021 Chevrolet Blazer. The contact stated that while driving approximately 10 MPH and attempting to make a left turn, the vehicle stalled. The contact depressed the accelerator pedal aggressively several times to get the vehicle to start moving again. The failure reoccurred while the contact-??s daughter was driving and attempting to make a left turn at a green light when the vehicle stalled. The contact stated that the failure persisted while driving and attempting to turn to the left. The failure occurred intermittently. The contact stated that only the rear tires would move. The contact took the vehicle to the dealer who was unable to find the cause of the failure. The dealer was not able to duplicate the failure. The failure persisted. The manufacturer was made aware of the failure and opened a case. The approximate failure mileage was 28,000.

I went out to start my car and the light said that it was not reading the key fob because of low battery. I went and got the other key fob which had never been used and had the same result. The car was towed by Chevrolet to the dealer and it has been there for over 3 weeks. They found that it wasn't a faulty key fob but it was the receiver that gets the signal and allows the door locks to open and the engine to start. I tried moving the shift lever, stepping on the brakes, trying the remote start on the key fob and nothing would start the car nor would it lock/unlock the doors. It just kept giving me the notice that it couldn't read the key fob. I called ONSTAR and tried the actions they told me but that did not work either and they said to contact my selling dealer. ONSTAR contacted the Chevy warranty number for a tow truck but at 9PM it was too late for them to make a service call. What if I was out in a parking lot or in a remote area and experienced the same problem with no assistance. I have been trying to find out what the dealer is doing to repair my vehicle but I have to call the GM complaint line in order for them to try and contact the dealer about my car. They finally gave me a rental vehicle since the vehicle is less than 1 year old and only has about 6,000 miles on it.
