Engine showing PO128 code. Steering Assist System reduced power. Engine fan constantly running. Engine temp on dash is stuck on the "C" mark, doesn't move. Thermostat and temp sensor replaced, issue continues. THIS IS A VERY COMMON PROBLEM ON GM VEHICLES WITH THE 3.6L AROUND THE 60,000 MILE MARK. GM NEEDS TO GET IT FIGURED OUT.

I received a check engine light which i took to Bell tire for diagnosis. Here is there diagnosis Comments: The P01F0 code on a 2020 Chevy Blazer means the engine coolant temperature is below the normal operating range, often due to a stuck-open thermostat (or both thermostats in models with dual units), a faulty Engine Coolant Temperature (ECT) sensor, or low coolant, leading to poor fuel economy and potential wear; fixing it usually involves replacing the thermostat(s) or sensor after checkin

"I was in extreme danger while traveling with my [XXX] child in the vehicle on the day prior to the total failure. During that trip, the transmission began to slip significantly in active traffic, creating a terrifying loss of motive power and a high risk of a rear-end collision. Because of this dangerous incident, I attempted to reach the dealership the following morning to prevent a crash. Upon arrival, the transmission suffered a total catastrophic failure in the dealership lot. Had this fin
The driver information center suddenly indicated steering assist disabled, temperature gauge drops to below cold, air conditioning blows warm air. This issue has happened several times and is able to be reset by disconnecting/reconnecting the battery or using a scan tool. Temperature sensor is not the cause in my opinion, and I have read that the harness for the temperature sensor also includes the coil wires, which can lead to electrical/rf interference, triggering this issue. I have read ab

I bought this car brand new. 0 miles. Iâve had an oil leak fixed once in it. And now itâs leaking oil again.
