ELECTRICAL SYSTEM, ENGINE
Action Required "Steering Assist Warning" drive with caution, Temp gage reads cold, A/C stops working, engine cooling fan runs on high speed (even after the engine is shut off), pending P2018 code, with no Check Engine Light (CEL). Replaced Engine coolant Temperature (ECT) sensor, problem did not go away. Several reviews suggest to replace the thermostat, check fuses for proper insertion, reroute ECT wiring, and possibly replace radiator. Most of these repairs can be very expensive. Chevy Blazer Forum states that the issue is a out of range detection of ECT sensor reading. GM needs to determine a true solution and stop guessing at owner expense/frustration.

SERVICE BRAKES, ELECTRICAL SYSTEM
Incident Description: While my wife was driving our 2022 Chevy Blazer at approximately 40 miles per hour, the vehicle’s dashboard suddenly went dark and became unresponsive. Multiple warning lights illuminated simultaneously, including the check engine light, ABS light, and other system alerts. The dashboard appeared to flicker as though it was repeatedly shutting down and restarting. When the brake pedal was applied, it offered no resistance and traveled completely to the floor without slowing the vehicle. To bring the vehicle to a stop, my wife shifted into neutral and allowed it to coast until it came to a complete stop. Fortunately, there were no intersections or other vehicles in front of her at the time, preventing a potential accident. This incident raises serious safety concerns, as both electrical and braking systems appeared to fail simultaneously.

VISIBILITY/WIPER
I was driving on a rainy day, and noticed my windshield wipers were not working. I tried adjusting wiper speed and even the spray function, which sprayed but did not wipe. At this point I had driven over a mile and had to pull over because visibility through the windshield had gotten so bad. I restarted the car and the wipers functioned normally again. There were no warning lights of any kind or software notifications, and the wipers had worked previously that day.

ELECTRICAL SYSTEM
Published date: 09/6/2024 Preliminary Information PIT6231 Poor Sound Quality On A Phone Call GM Dealers are not recognizing this service bulletin to remedy the microphone issue. This is a life safety issue and a formal recall notice should be issued. Reason if the driver or passenger is injured in the vehicle the same microphone is used to communicate with the SOS and On start. when some one is incapacitated or suffered an injury they would not normally be able to speak in such a loud volume for the recipient to hear and when the person speaking who has been injured is forced to yell into the microphone (if able) the receiving end only will her distorted audio,. It is for the reasons set forth above I respectively ask that this be considered a recall and not addressed by a service bulletin

ENGINE
Put my car into park and the fan kept running continuously. I noticed that the engine temperature gauge did not move off of cool either. When I drove it, I got an alert that the ‘steering assist was reduced’ and shortly after my check engine light came on. My safety was at risk due to the fact that I couldn’t monitor my engines temperature and it very well could have been overheating and I would’ve never known. I took it to the dealer and they did confirm that my thermostat was stuck open and wasnt allowing my engine to get up to temperature. My ecm module had to be replaced as well. The mechanic said, had it closed my engine would’ve overheated with no signs until it was too late.

FUEL/PROPULSION SYSTEM
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.

POWER TRAIN
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.

SUSPENSION
Control arm snapped on the I-71. Going 70 miles an hour when it happened. Definitely could have been a major accident but luckily no cars were around us when it happened. i rode over a bridge's transition and heard a big pop like a tire. Then it sounded and felt like we were riding on a rim. When we got out we saw what had happened. No warnings or anything before this happened.

POWER TRAIN
Automatic transmission and radiator. Vehicle shifted hard and then would not go to a higher gear after pulling out into an intersection. Vehicle was pulled over to side of road and shut off. Restarted and tried to merge back onto main road and while trying to accelerate, the rpm’s went over 3500 quickly and wouldn’t shift once the vehicle hit 30mph. The engine light came on. There has been no previous engine lights or issues. Scheduled an appointment at a Chevrolet dealership and had the vehicle towed on a flatbed trailer to be looked at. I stated that there was a major problem/issue with the transmission and explained the problem. In their notes it states they took it for a test drive before even checking the transmission fluid for metal particles. I told them it was a severe failure and was barely drivable. It was able to drive up in the trailer to be towed, but never shifted out of 1st gear. We are a little over 64,000 miles and the warranty cut off is 60,000. The dealership states that the transmission needs replaced and the cooling system as well since metal particles made it into that system as well.

ELECTRICAL SYSTEM
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.]

STEERING
While driving, the vehicle displayed a “Service Power Steering” warning message, and shortly after, the steering became noticeably heavier and less responsive. The issue occurs intermittently but has worsened over time, creating a serious safety concern because loss of steering assist could occur at any speed. The dealer diagnosed the problem as a failure of the electronic power steering module and rack-and-pinion assembly, quoting an estimated repair cost of approximately $2,500. The vehicle has only around 56,000 miles and has been maintained as recommended. The dealer confirmed the issue but stated that General Motors would not cover the repair under warranty or goodwill assistance. This defect poses a significant safety risk, as a sudden loss of power steering assist can make the vehicle difficult to control, especially during turns or emergency maneuvers. There were no accidents or injuries, but the potential for loss of control is high. The warning message and loss of assist can be reproduced and have been verified by the dealership. The vehicle has not been repaired yet, and the defective parts are available for inspection upon request.

FUEL/PROPULSION SYSTEM
This is the 2nd time I have been left stranded unable to charge my vehicle due to the charge door malfuction on the vehicle. This is a safty issue due to the fact that if you are unable to charge the vehicle, you can get starnded somewhere unsafe putting yourself and family at risk. This charge door failure has happened once within 8 months after purchasing the vehicle, the charge door was replaced under warranty back a year ago. Now its has started to bind up and not open leaving me unable to charge my vehicle. I have taken the vehicle back to the dealership and they had to special order the part. Currenty I have not been able to charge my vhecile properly. I have to forcefully open the charge door causing more damage, until the part is replaced. Please look into this issue, I have contacted other Blazer EV owners and have found they too have had the same peoblem.

STEERING, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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

ELECTRICAL SYSTEM
The infotainment system of a brand new 2025 Blazer EV is doing blackouts, flickers, and changing commands and requests. While this may sound trivial - and if this system just did the radio - I would agree. However it controls most all the sub-systems of the car from Charging, to Display, to GPS, Environmental, etc. While at home it is just annoying and frustrating - we traveled to VA from FL this past week. Traffic was horrendous due to a closure of I95 in SC - ALL traffic was forced onto 2 lane country roads. Attempting to use the Controls, adjust GPS for alternatives, and adjusting displays - the glitches were causing either unexpected actions - or distracting longer than expected and causing near accidents. In addition I report that the "collision avoidance" is marginal or dangerous. Dangerous with it engaging maximum braking for a Marker-Barrel that no where near my path - to not engaging well enough when vehicles were rapidly braking (and they did not have brake lights). Finally - the GPS system "changes" destinations on its own. Again with the display flashing and blacking out - it is difficult to notice these "changes" when travelling on back-roads with insanely heavy traffic.
