Intermittent dash warning: "action required. Steering assist is reduced. Drive with care. " power steering is sluggish when this happens. Having this happen while driving could be dangerous. Only stays on for a few minutes then goes away. This started with only 10k miles and has been continuing for 2+ years. Based on what I've read online, this is a known issue with the thermostat and/or coolant temp sensor. Dealership refuses to fix it unless it's throwing a code while in the dealership. Of course, it never throws the code while at the dealership.

The Blazer's check engine light came on and I had it scanned. The code was po128 indicating that the engine coolant temperature is consistently below the thermostat regulating temperature. We are also getting a message on the vehicle that states the steering assist is reduced, drive with care. The car is also blowing hot air when the ac is on, the temperature gauge is staying at the lowest setting and the fans are running full blast. This seems to be a very common problem with the Chevrolet Blazer.

Vehicle gives warning that steering assist is disabled. I should drive carefully. Also cooling fans run on high and temp gauge reads zero. P0128 I'd code given by computer. When code is cleared vehicle returns to normal operation. I read many, many people have this same problem with no clear correction. Many have replaced thermostat, temp sensors, and problem returns. Sounds like defective wiring to me and if it impacts steering should be an oem problem to remedy.

Temp gauge intermittently reads cold, no ac and engine cooling fan constantly blowing, dash warning re power steering, 40,000 miles, code po128, review of google indicates this is a common problem and likely needs a new thermostat and ect.

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.

Steering assist reduced warning is on all the time. Fan is on overdrive and thermostat needle on cool all the time. Leaking camshaft actuator solenoids.

Steering assist reduced drive with care display, air conditioning turned off, stop and start disabled, temperature monitor at cold, fan blows hard why my 2020 model was not covered under the special coverage n252508350 NHTSA id# 11024390.

Coolant temperature would not read, steering assist malfunctioning, air conditioner intermittent. Wiring harness for sensors loomed together with coil pack wiring interrupting signals.

Thermostat has failed. Mechanical failure not related to steering the vehicle - has caused a safety concern.

The thermostat and the sensor for the thermostat continues to go bad.

I keep getting a message "action required. Steering assist is reduced. Drive with care. " the code I get is p0128. I hear this is a common problem and I think gm needs to recall this problem.

Where do I start. Spring of 2024 I believe, less than 55,000 miles, my transmission went out. No warning. I just went out to my vehicle to go to work and when I put it into reverse, my vehicle make a awful noise, jerked forward almost going into my garage door, then wouldn't move. . I put it back in park, tried to put into reverse again and it wouldn't go. It was stuck in park. Had to get it towed to the dealership where they advised me the transmission went out. It was covered under the drivetrain warranty, but the gm warranty doesn't cover rental. It took almost 4 weeks for gm to approve for a new transmission due to parts being on back order to rebuild my transmission. Several months later, I was driving down the road when the esc light and then it said "shift to neutral & press start" and I lost power. I coasted into a parking lot, got it fired up, but had no air conditioning (of course it was summer). Took it to the dealer and they said my radiator and a/c compressor had to be replaced. Luckily my extended warranty covered the $5000 repair. Now 4 months later I got "steering assist reduced, drive with care" with codes. Took to shop and the codes basically was the temp was to low, but the shop couldn't find anything wrong. Cleared the codes and so far so good, but now my esc light pops on once a week again. I don't even have 60,000 miles on my vehicle.

Driver steering assist reduce message in display. Upon scanning codes, error code p0128 triggered. Temperature gauge does not register on dial between c-h.

Steering assist is reduced came on dashboard. Check engine late came on shortly after. Ac wasn't working and the temperature gauge on the dash wouldn't move. I took it into a shop where they said it was a temperature gauge that was causing all the issues and would need to be replaced. P.

Consistent Blazer issue. Error coded “steering assist reduced. Please drive with care”. There is a thermostat issue. Causing the car to sputter and not run properly. This a common issue with Blazers and a manufacturer default. Should be recalled and covered. It is a safety issue.

Reduced steering warning, the temperature gague is stuck on c, radiator fan is running on high as soon as I start my car and the transmission is shifting hard at second and third gears.

At around 55,000 miles my Blazer began to show error codes for “steering assist reduced” and “esc”. After 60,000 it began to intermittently populate the check engine light paired with the "steering assist reduced" message. Then, the engine fan would turn on high, auto-start when breaking would disable, and the steering would become more stiff. Finally, I was able to get a scan on the code and found out that it was my thermostat. After taking it to my local chevy dealer I was quoted $1100 to repair. When I called my local mechanic I was told they could fix it for cheaper, but they were unable to find an oem thermostat in stock which usually means there's a widespread issue with that part. Upon further research, I've found a plethora of complaints online where others with chevy vehicles are experiencing the same issue. This causes: -greater fuel consumption -risk for the engine to overheat -stiffened steering which could cause accidents.

Nothing necessarily happened, but I've been getting the "steering assist reduced, drive with care" pop up, which assist I've been reading might mean a faulty thermostat. Sounds like a common issue and may e time for a recall? only 60k miles on my Blazer.

This is 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.

Common issue, the steering assist is reduced and temp gauge is stuck on c. This either a thermostat or temp sensor issue.

I have a 2021 chevy Blazer that has 31,0000 miles and my steering locked up. I was driving and barley got into a parking lot. Told by a certified dealer it is the power steering gear and possible the power steering module. No parts available and no eta. This does not make sense that the steering with such low miles has gone out. I have read on the gm forum that multiple people have had this issue. I could have been killed. Why has there not been a recall on this very expensive repair?.

The Blazer is having a recurring p0128 code. We have informed the dealership. This has been going on for 2 years or so. I reset the code with a code reader and it stays off for a few months usually. Tried to have the dealership look at it one of the last times it happened but they wouldn't just look at it. . . They wanted to set up an appointment. We needed the car so I reset the code again. Now it is time to get it fixed. I know it needs a thermostat and temperature sensor. The cost to install it will be close to $1000. This should not be at my cost. This is a know issue with the 3. 6l engine and it affects the emissions of the vehicle along with many other parts of the engine. I am reaching out to see what can be done.

P0128, ac not working, steering assist reduced, and temp gauge not working. Problem caused by faulty ect wiring. First the problem is the ect is a two wire (signal + and -) 26 gauge wire running through the ignition coil wire harness. Ignition coil signals are very high voltage and fairly fast frequency which causes a lot of emi which is easily picked up on a 2 wire voltage based wire set. The ect wiring should have been a twisted shielded pair if running next to coil wiring or they could have used a single wire resistance thermistor, but they should have just routed the signal a different way to begin with. This is a design issue and it should be a recall. . . Maybe a class action lawsuit is needed to force them to fix it correctly. The fsb (field service bulletin) fix blames loose connector terminals and it patches the computer software to not include ect wire failures in the steering, ac, and temp gauge inhibit logic (overtemp readings will still fail off these functions). Also the p0128 code can come back occasionally.

My 2019 Blazer gave a steering assist warning on 2 Nov 2024. I was aware of a recall for other Blazers but for some reason my VIN was not among those recalled. I took it to the dealership on 6 Nov 2024. The dealership has determined that the issue is indeed the same issue with those other Blazers that have been recalled but refuses to include my car in the recall because the VIN number wasn't originally among that recall. I was told that the car needed anew temperature gage and that they would have to order it, however, the component was available outside of the dealership. I paid for the diagnostics and the part, being told that the light(s) would stay on, I would still be able to drive it and that I would receive a call when the part came in. It is my understanding that the steering assist reduced can affect the power steering and essentially revert back to manual power steering, potentially causing a loss of control while driving and increasing the risk of accidents. There were no warnings of the steering failure assist warning. It just appeared on Nov 2, 2024 at 1130am. About 1240pm I noticed that the temp gage was inop and the check engine light was now illuminated. I contend that because gm has already identified the thermostat issue serious enough to do a recall, then all Blazers with that recall issue, VIN number aside, should be given the same consideration and not have to pay for something that gm has already taken responsibility for. The dealership however does not agree for the simple fact that the VIN was not identified in the original recall.

Steering assist reduced message comes on and temperature guage goes down to cold not working and after you shut car off fan runs full force for 10 minutes. Shows no check engine light or no codes.

The contact owns a 2020 Chevrolet Blazer. The contact stated that the transmission was slipping while driving in the lower gears.

My shift to park comes on although the vehicle is parked my steering is reduced came on today this is a problem in mutiple forms in regards to chevy Blazers.

I keep getting this message that pops up, "steering assist reduced drive with care". At the same time this happens the temp gauge stays on cold, the ac quits working, the engine fan is on high, and most of the time I get code po128. We have had it in to the dealer and they said the its the thermostat or the temp sensor. From what I am reading it could be a factory issue with the emi issue from sensitive ect circuitry. This has been an ongoing issue for us for over a year.

Message pops up saying steering assist is reduced please drive with care. Then the car fan runs all the time on high and the cars temp gauge is running all the way on cool.

Vehicle keeps throwing “steering assistance reduced please drive with care” message. It causes my car fan to constantly run. It also causes the coolant gauge to not work the needle drops below that cool like it’s not on and then the car won’t blow cold air from the vents. This message tells me that something could be wrong with the steering which puts my safety at risk. This issue has been happening to me on and off for months now and there are multiple complaints of multiple chevy owners having the same problem this issue needs to be addressed.

Steering assist reduction from coolant temperature reading malfunction. Power steering reduction risking potential loss of control of vehicle. Code confirmed by chevy dealer.
