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.

Upon driving my vehicle twice it shut off on the roadway once on an incline when a message of 2 keys detected and flashed on the dashboard prior to the vehicle shutting off. Vehicle would not restart until 15 minutes later it restarted but the dashboard kept flashing 2 keys detected. There was only one key in the vehicle at the time and the key fob has had the battery replaced upon the first incident which was on 11/14/2024 and the second incident was on 11/16/2024.

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.

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.

Instrument cluster completely blacked out, providing no information on vehicle speed or status of operation. Operation of a vehicle without instrumentation would seem to be a safety risk. Chevy dealer diagnosed problem as IPC error U0155, installed updated software to correct the problem. The repair was not covered by the extended warranty I purchased through General Motors when I bought the car. I think a defect such as this should be the manufacturers responsibility, I believe GM has a service bulletin out for this problem covering several models of their vehicles. This should be upgraded to a recall.

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.

While driving on the highway at speeds above 60 MPH, the engine shut off. There was a slight shuttering immediately prior, but no other indication. I had to pull over, across three lanes of traffic, during rush hour, in a fairly heavy rain and became a disabled vehicle on the shoulder. After being towed to the dealer, it was determined that the fuel pump was faulty. The vehicle had 4,954 miles on it so there was no reason for this part to have failed so early.

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.

Vehicle now has about 1200 and when driving, the instrument cluster panel that digital shows your speed, odometer and other information on my vehicle went blank. It is just a black screen. When this happened, it caused the steering wheel controls for radio volume and turning the station to not work. With this, I have no safety features like lane assist now and can't tell my tire pressure.

Headlights flash or stay on either low or hi beam, hatch opens itself, AWD poping, noise in dash, shifting into AWD by itself, transmission not shifting correctly. There is no pattern and it throws no codes. Major electric problems. The keyless entry pad didn't work the day I purchased my car. Had a new one installed 3 programs and now all this started.

- Davenport, VA, USA

While driving the the whole dash goes blank for a few second, then then it reboots and eventually most of it comes back. However, it did this repeat this cycle and cannot tell if my signals are working or what my speed is. I have a video of it happening. The car has 2,700 miles.. I am taking to a dealership
