2019 CHEVROLET BLAZER Complaints

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.

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.
