2019 Chevrolet Blazer complaints

We have a start / stop issue with our 2019 chevy blazer . the dashboard states to put into park .we cannot turn car off with this on dashboard . why is this not a safety recall , because we have seen a lot off people complaining about the same issue . WE CALLED THE CUSTOMER SERVICE FOR GENERAL MOTORS CORPORATE , and they told us there is no recall for that . we also got a postcard from a lawyer stating there is a settlement this . what are legal options to get this resolved .

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.

35,000 miles and P0128 code that does not resolve after expensive repairs of coolant Temperature sensor and thermostat multiple times.

My transmission can accelerate with the cruse control on, transmission also sputters at lower RPM. Lastly my shift to park issue kills the battery.

P0128 error, power steering reduced warning, cooling fans on, no a/c and temp gauge stuck on cold

"shift to park" message appears when parked (even if safety brake is engaged) and attempting to turn off the vehicle. The vehicle does not turn off and remains running for various periods of time. Unable to turn the vehicle off, leaving it unsecure and drains the battery. This happens consistently. I contacted my local dealership and they confirmed getting several of these reports through their shop, but no recall has been made.

My check engine light came on (solid) and my AC stopped blowing cold air and my auto start stopped working. I used a diagnostic tool to read the code and it said "P0128 Coolant Thermostat $07e8". The same thing happens with my heat when it gets too cold out.

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.

Engine - code p0128 engine coolant thermostat. This is a safety issue because it reduces the power steering on vehicle, auto stop stopped working, unable to remote start vehicle. Issue has been confirmed at an independent service center (I work at an auto collision center). Warning lamp - check engine light. Message on dash - power steering reduced. Appears everything came on at the same time. Per dealership items most likely needing replacement are engine coolant thermostat and engine coolant temperature sensor but ecm module could also need replacement. Advised common problem but no recall power train - transmission shutters when accelerating. Safety is at risk because vehicle will not accelerate or accelerate too quickly. Called to dealership advise flush transmission fluid twice to fix issue. We have done this 4 times in the past year. Shutter temporarily reduces but does not go away. Per service advisor it is a "function design" and if flushing transmission fluid does not fix issue then transmission will need to be replaced. There are no warning lights or messages on dash electrical - vehicle says shift to park when vehicle is in park and will not allow vehicle to turn off. It is a safety issue because vehicle will not shut off. Problem confirmed by an independent service center we have already replaced the in-line wire harness jumper. This did not fix the issue. Advised from service center that entire shifter would need to be replaced.

Action Required: Steering Assist is Reduced Drive with Care & Check Engine Light comes on after the alert message. When these are on, the ac does not get cold. Unhooking the battery resets it for a few days and then it comes back on.

Coolant Thermostat needs replaced at 59945 miles. The temperature gauge stopped working and the A/C unit shut off. The temperature outside created a safety issue for my family and I to ride in the car. The engine light came on and a message that stated the Steering Assist was effected. This should not happen in a car under 60000 miles.

1. Wire harness with coil wires is the problem. It was fixed by a local shop and the vehicle can be inspected if needed. 2. The car throws a code for a faulty thermostat/coolant temp sensor. This will not allow the car get to oporating temp and could cause engine damage or not perform properly causing risk of an accident. Also this will reduce the driver assist features such as lane assist and adaptive cruise/braking. 3. Yes. 4. A local shop inspected the thermostat and coolant temp sensor and they oporated as they should. 5. The engine light comes on for the reasons mentioned above. It also has a "driver assist reduced" message. It appeared randomly while driving and stayed on for multiple days. Vehicle had a code for a bad thermostat/coolant temp sensor and "driver assist reduced" message. The cause is NOT the temp sensor or thermostat and is actually a wiring harness that two wires need to be separated from the bunch. The frequency from one wire interferes with the coolant temp sensor wires. I am on several forums for chevy blazers and there are TONS of posts about this issue with the 3.6 V6. Most people will go in and have these expensice parts replaced. It is not acceptable to have people get charged for a $800+ job when the part is not faulty.

Po128 temp. Below normal, happens on a regular basis, at least 2 times a week,

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

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.

I bought a 2019 Chevy Blazer in February 2023 . The vehicle has issues when I fill it with gas. As soon as I gas up to full it starts jerking immediately afterwards. It makes loud popping sounds. The engine dies completely. It starts to tremble and will not go. When I try to turn in back on , the starter works very hard before it will turn back on. It does turn back on eventually but I have to pull over to the side and accelerate the engine until it finally stays on. I drives that way turning off at lights and stops. After about 10-15 minutes of this , it finally stays on long enough to drive another 20 minutes or so to get home. After it rests for a few hours, it goes like normal. This is a big safety concern for me since these episodes happen every week when I fill up my car with gas. I have almost been hit from behind during these episodes and it is very scary and such a hassle to have to deal with this every week. I have already had several Chevy dealers and mechanics work on this problem and it continues to act up like this. I have all the paperwork for the work that has been done. $15, 000 have already been spent on this problem and the problem still continues. Please help me. I like chevy vehicles and have always bought chevy but this is the second chevy vehicle that has given me problems when I gas up. Please look into this problem.

Thermostat clicking off, internal cab thermostat not reading going to C, and air blows hot

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

AC not working, Temp Gauge stuck at C, Steering assist reduced Happened a year ago, went away, came back. Would fix short term if battery was disconnected and reconnected or if code was cleared. Found lots of others with this same issue

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.

Steering assist is reduced driver with care

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.

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.

When I go to put my car in park, I get a notice warning chime to shift it into park. Which then results me into not being able to turn off my car. I am then forced to sit in the car and try to wiggle the shifter until it registers that the car itself is in park. . This first happened to me a few days ago with my toddler and infant child in the car. Compromising my safety as well as the safety of my children, since I was now forced to sit in a public parking lot with my kids in the car trying to not only turn off the car, but also trying to make sure my car was properly parked and not an endangerment to others. I recently called a dealership on feb26,2025 and found out I had the problem fixed once before in 2021. I’m now currently working on getting my car to the dealer to get this issue resolved asap. Which is an inconvenience to me, my schedule as well as the schedule of others, since I now need assistance getting to and from the dealer along with taking my children to school and or appointments.

When attempting to put my car in PARK, the car issues a warning stating the car is not in PARK, it doesn't recognize the gear shift being in park, therefore, I am unable to shut my car off or lock it up. It is a known manufacturing defect and GM refuses to cover the cost to add a bandaid to it as there is no permanent fix. This is a safety issue, and now my car is not reliable, nor safe. GM refuses to issue a recall on this.

The contact owns a 2019 Chevrolet Blazer. The contact stated while driving at various speeds, the vehicle accelerated and decelerated independently. The contact stated that the message to "Shift to Park" was displayed while shifted to park(P). The vehicle was taken to a local dealer and the contact was informed that the gear shifter needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the local dealer; however, the failure was not duplicated. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 61,000.

When I shift the car into park and turn it off I get a message that it isn’t in park though it is as displayed on the console. To clear the message I have to move the shifter back and forward several times. I’ve had it in the shop twice already but the problem continues to return. This should be a recall!!

With great frequency when I put my 2019 Chevrolet Blazer into park position I receive the error message to "Put vehicle into park" when it is in fact in the Park position after done driving. I've tried putting the car into drive again or reverse then back into park position or trying to turn the car off then back on and this does not clear the message. I am unable to turn the vehicle off completely until the message has cleared. The vehicle remains in Auxiliary mode until the message has cleared which takes several attempts. This is a huge inconvenience!! My local Chevrolet service center has checked my VIN information and there are no active, repaired or expired recalls for my vehicle. This has been a long time issue with this type of vehicle according to the Blazer forum. PLEASE ISSUE RECALL FOR THIS ISSUE ASAP!

SHIFT TO PARK MESSAGE COMING UP ON DASH SCREEN EVENTHOUGH SHIFTER WAS IN PARK. ENGINE WOULD NOT TURN OFF. HAD TO SHIFT SEVERAL TIMES FOR VEHICLE TO RECOGNIZE PARK . THERE WAS A RECALL ON SOME 2019 CHEVY BLAZERS AND A TECHNICAL SERVICE BULLETIN ISSUED, BUT MY VIN NUMBER IS NOT ON THE RECALL LIST. THE CURRENT MILEAGE IS 37752. I BOUGHT THE VEHICLE NEW. DEALERSHIP RELACED SHIFTER CONTROL AT A COST TO ME OF $553.60. IF THERE IS A SAFETY ISSUE, SHOULD A RECALL COVER ALL ?

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation. GM has already identified this recall for other VINs of 2019 Chevy Blazers I believe it should be extended to additional VINs.

I recently stopped at a local store and put the car in park. A message appeared on the dash Shift to Park. I was not able to turn the car off and I had to move the gear shift back and forth until the message went off. I couldn't lock the car correctly by moving away from it. I used the key fob to eventually lock the the car. My concern is that if my wife is driving, she may not be able to lock or move the vehicle. This seems very unsafe. Should this be brought to the attention of the local Chevrolet dealer?

The contact owns a 2019 Chevrolet Blazer. The contact stated that the gear shifter had repeatedly become loosened, causing the gear shifter to move in a circular motion while in park(P). The contact stated that the "Shift to Park" message was displayed while the vehicle was in park(P). The contact repeatedly struck the back of the gear shifter while in park(P) to correct the failure. The gear shifter had been replaced on four separate occasions. The contact stated that the first three failures were repaired under warranty; however, the contact recently had to pay out of pocket for the last repair. The contact stated that the failure had returned. The manufacturer was notified of the failure but offered no assistance. The failure mileage was unknown.

Shift into Park warning when turning vehicle off even though vehicle is in park.

When i put my car into park and go to shut the car off if starts saying put car in park even tho it is already in park. It will not allow me to fully shut car off when it says that. I usually have to put it back into drive and back into park again for it to register.

When placing the vehicle into park there is often a issue with the sensor recognizing that the vehicle stating that it is not when attempting to power off the vehicle. When stopping there are times that the vehicle is difficult to stop and there is not fault code as to what may be occurring.

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

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

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

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.

The contact owns a 2019 Chevrolet Blazer. The contact stated that they began to notice the grill at the front of their vehicle begin to flake slowly over time. The flakes had grown to the size of a dime. The vehicle was taken to the local dealer, where the contact was advised that the dealer would cover half of the cost to replace the grill. The vehicle was not repaired. The manufacturer was notified of the issue.

2019 Blazer with 73,399 miles is in Park, but displays "Shift to Park". System does not recognize that the vehicle is in Park. Vehicle will not turn off even after shifting transmission to drive and then to Park again. "Shift to Park" message won't reset. Dealership said it's $1,642 to fix issue. Afraid to drive the vehicle because it won't shut off, can't be locked, and will run out of gas/battery if "Shift to Park" displayed message can't be reset/fixed.

My 2019 Blazer won't shut off the electrical system because of a "shift to park" error. This causes a drain to the battery and could leave me stranded. The problem is simple electrical switch that is not making the connection to tell the car to shut off. This is a well documented problem with chevy vehicles in the late 2010s and includes multiple models. I have not had the problem verified by a Chevrolet dealer. I've reviewed multipe youtube videos that has had 10s of thousands of views which demonstrates the problem is very wide spread. Why is this not being recalled?

When placing the vehicle in the park position and attempting to shut the vehicle off with the push button my DIC flashes a message stating to 'shift vehicle into park'. I have to move the shifter from park to another gear several times in order to keep this from appearing and allowing me to turn my vehicle off. I can take up to 5-6 times before I can get the vehicle to allow me to turn it off. I'm not really sure if it is or isn't in park even when I do this at that point. I have had this happen on multiple occasions over multiple months.

The vehicle is not recognizing the car is in PARK when it is placed in Park.

The contact owns a 2019 Chevrolet Blazer. The contact stated while placing the vehicle in the park and attempting to turn off the vehicle, the message "Shift to Park" was displayed on the instrument panel, enabling the ability to turn off the vehicle. The transmission failed to lock the vehicle in park for the vehicle to be able to turn off. The vehicle was taken to the dealer where it was diagnosed that the harness Part Number: 84733196 and the switch Part Number: 84955379. The vehicle was repaired. The manufacturer was made aware of the failure and confirmed that there was no recall for the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 19,563.

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

When the vehicle is shifted into park the indicator on the dashboard and the on the console next to the shifter display 'P' but when ignition is turned off a warning on the dash shows shift into park. It is on the web with multiple complaints. This problem appears on other GM platforms.

We had the shift to park issue 3 years ago and fixed it. Cost near $300. Now we are taking it back in for the same exact issue. In addition to this issue all the lights on the dash board keep coming sporadically and on star sent us report with a ton of engine and transmission issues.
