ENGINE
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.

ENGINE, ELECTRICAL SYSTEM, LANE DEPARTURE: WARNING
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.

STEERING
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.

FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
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. My phone number [XXX] if you need to make contact with me by phone. Thank you [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

POWER TRAIN
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.

POWER TRAIN, BACK OVER PREVENTION: WARNINGS
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.

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!

SERVICE BRAKES, ELECTRICAL SYSTEM
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.
