Steering assist is reduced driver with care.

On Saturday, March 8, 2025 I was crossing a busy intersection when my car shut off completely and accelerated into oncoming traffic almost causing a collision or fatality. My brakes locked and steering wheel locked. I had to put the emergency brake on in order for the car to come to a stop. We got out of the car in the middle of the street and ran for safety. Scariest experience I’ve ever been in especially with my family in the car!!.

1). Engine stopped on interstate hiway with just 2024 miles. Towed to chevy dealer. New engine installed. Upon return of car emission system failure. 2) car delivered with defective windshield with major (crackle) throughout very distracting at sunrise/sunset. Replacement not much better.

Vehicle is available upon request. 5/28/23 tires needed replaced, not even 30,000 miles on car. Customer was charged. 6/13/23 struts and mounts replaced at dealership 3/29/24-revs high when barely touching pedal. Turned car off and it started back up on its own. Happens at least once a week. Dealership was unable to recreate. 4/1/24- wheel bearing replaced, customer was charged. April 2024 black metal showing through white paint. Paint was thin and fading. Dealership repainted the 2 doors that had paint issues. 12/20/24- antifreeze level was at bottom of reservoir. Sloshing noise when driving. Was told air in hoses and will work it's way out. Was back at dealership 1/15/25, 1/24/25 & 2/5/25. Radiator fluid still dropping but even with dye test they can't figure out where it's going. Terrified it's going to effect the water pump and engine.

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.

“shift to park”message appears when I shift to park and turn car off.

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

There's a glare from the dashboard that's reflecting on the windshield and causing an obstruction to road visibility.

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.

I am having a problem when I shift my car into park to stop the car it will shut the engine off, but it will not shut off the accessories, and I have to restart the car and tried over and over again until it shuts off. Also the dash lights up to shift the car to park, but I already have.

P0128 code- assisted steering fault check engine light ac blowing cold temp gauge flat lined need to replace temp sensor and thermostat. Others with this issue have reported steering can completely lock up, which could cause serious accidents which could result in fatalities.

Yesterday I received a message saying driver assist reduced. Today received the same message, and heard a whirring noise when car was started.

When putting the vehicle into park, we are receiving a “shift to park” error. This issue appears to be common among thousands of general motors vehicles. However, the dealership is unable to assist us because the repair bulletin only applies to the 2019 model year and does not include the 2020 model year. Despite this, the issue we are experiencing is identical to the one reported for the 2019 model.

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.

Steer assist and thermostat issue. The vehicle has 42,000 miles on it. Have not been able to obtain/find a new thermostat since November 2024.

My check engine light is on the, the temperature meter is stuck on cold, the a/c only blows hot air, and the engine fan is blaring loud as heck the moment the car is started. Also it keeps telling me the steering assist has failed. I have replaced the battery and checked the coolant. Still the same issues.

While my wife was pulling into park the car and pressing the brake, the car all of a sudden accelerated into the building. Pressing the brake failed to stop the car. No person was in the way of the car so no one other than my wife was at risk of injury. The problem has not been reproduced since the car was totaled. The car was inspected by the insurance for loss but that was it. Police and manufacturer have not inspected the car. No warnings were presented prior to the accident.

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 vehicle is not recognizing the car is in park when it is placed in park.

2020 chevy Blazer - shift to park while gear is already in park: while putting the gear in park, the warning chime to shift it into park is initiated. It has happened 3 to 4 times in the past three days. I took the vehicle to the local chevy dealership. The service team/dept. Diagnosed that the transmission shifter unit assembly must be replaced. The 2019 chevy Blazer had these issues which prompted a TSB/recall however it wasn't extended to the 2020-year models and chevy dealership refused to include it as a warranted repair which just passed 44,000 miles. This is a safety issue, and it should be replaced without additional cost to customer as this issue was already identified as a safety concern in 2019, however chevy does not want to identify the issue as a covered repair per the manufactures warranty.

After I shift into park and press the button to turn my vehicle off, I receive a message on the dash that states "shift to park" and my vehicle will not turn off. This has happened on several occasions, but does not happen every time I attempt to turn my vehicle off. When I do receive the message, I usually have to restart my vehicle and move the shift out of park and back into park before I can turn the vehicle off. Sometimes, I am able to get the error message to go away by jiggling the shift.

When car is put in park and cut off the vehicle doesnt recognize its in park and a light comes on saying “shift to park”. I have to keep pushing gear shift forward repeatedly even though its in park already. The car will not fully turn off till this error message is cleared. Ive had the car checked multiple times and the dealership states there is no code registering for this problem so they cannot fix problem so I cant get it fixed. Ive researched this and it is a known issue for multiple chevy models. Service mgr also stated its s known issue in multiple models.

The original issue was that the temperature gauge was pegged on cold and the a/c was inoperative. The vehicle’s fans would run continuously even when the engine was cold. This created a safety concern since the engine’s actual temperature could not be monitored, and loss of a/c affected drivability in hot conditions. The issue appears related to the engine’s coolant temperature sensor or thermostat system, which causes incorrect signals to the temperature gauge and hvac system. The condition has been reported by multiple owners of the 2020 chevy Blazer 3. 6l. In my case, the malfunction happened suddenly and has been repeatable. There were no prior warning lamps until the issue occurred, at which point the temperature gauge stopped working properly and the air conditioning failed.

The lift gate on my vehicle closed suddenly and for no apparent reason as I was loading groceries into the vehicle. The lift gate hit me in the back of the head and did not retract/open upon contact. I had to quickly lift the lift gate with both hands to get out of the way and press the button for the lift gate to open. A couple of minutes later, the lift gate again closed suddenly and for no apparent reason; however, I was not hurt the second time and was able to move out of the way and press the button to stop/open the lift gate.

When I shift my car into park, I’m getting a “shift into park” warning on the dashboard and alarm is sounded telling me the car is not in park while it is. The car won’t shut off.

When I am shifting my vehicle to park (gear shift in console area) and turn my vehicle off I will get an error code in my dashboard that I need to shift to park. My gear shift in the console is lite up p and my dashboard electronic system says p; but when I try to turn my car off it won't turn off and stays on again giving me the error code that need to shift to park. I then have to turn my car back on to then try and turn it off with the same error code coming on. I can try pushing the gear shift further with no success, shift to different gears back to park, and try waiting a few minutes after shifting to park before turning it off and still no success. This is a safety issue that my car is not really in park and will take off if I take my foot off the brake when this is all occurring. I at one point had to turn my vehicle on and back off with no success at least 5 times before I can finally get it to turn off. This problem has been confirmed by multiple Chevrolet dealerships with all of them saying they have seen many vehicles (same make and model with other models included) with this issue. Manufacturer knows about it.

When I stop and put my vehicle in park the panel lights up and says put car in park and it is in park. I am not able to shut off my car when this does that. There have been recalls on the 2019 Blazers for this specific reason. Mine did not make the cut. I had to pay $400. 00 to get this fixed from the Chevrolet dealership and it's the same thing that has been happening for the other 2019 Blazers that had recalls. I would like to be reimbursed. Thank you.

After putting the vehicle into park I received an error message "action required shift vehicle to park". I was then unable to completely shut the vehicle off or lock the doors and the alarm and notice continued to sound. I ended up spending over $1200 in repair costs and car rental to have the vehicle fixed.

When I put the car in park it does not register and will not come out of accessory more. This is a known issue and gm is making customers out of warranty pay for it.

The backup camera in my preowned 2020 chevy Blazer rs stopped operating within 7 months of purchasing Jan 13, 2024. It was replaced by local dealership. However, less than two weeks, it stopped working again. It's a safety feature that's not operational concerned may lead to accident. I did some research online where other owners have experienced the same problem.

2019 chevy Blazer rs - 39,217 miles and shifter assembly is malfunctioning and will not allow car to turn off properly and leaving lights, beeping and miscellaneous dash indicators on. This is a known issue with chevy.

The warning on the dash kept going off to shift my car to park. Had to restart my car over 7 times and shift the gear multiple times before I could get the warning to go away so I could lock my vehicle.

6/12/2024 in damon parking lot in rochester mn. Going less than 10 miles an hr- cars in front of me and behind me looking for a parking spot. Stop and go at times. Went to turn corner to go from one level to the next and my Blazer took off "like a bullet". No control over accelerated speed- hit outer cement wall and slammed into 2 parked empty suvs. Could not go any farther. The 2 suvs slammed into cement wall in front of them. Injuries to both my passenger and myself. I have no idea what happened - it was so fast- I do know I had no control over accelerated rate causing accident. My 2020 chevy Blazer was totaled- it was inspected by american national insurance CO. Absolutely no warnings. Police report did not include any witness. Blazer is in the hands of the insurance CO. Chevy Blazer took off like a bullet - could not stop it!!police report 24026393 rochester police dept unable to upload . Checked no police report below so I could continue report.
