Consumer Description

I took my vehicle to the dealership for the recommended oil change on 09/15/2023. I am extremely good about keeping up on the routine maintenance. Upon arrival, the technician asked if I knew that my check engine light was on. I stated no, it was not on during my drive in and has not been on previously whatsoever. I scheduled a diagnostic for 09/20/2023 and brought it back to the dealership with 68,191 being the mileage. It was determined that my thermostat needs to be replaced. I then began receiving the message Steering Assist is Reduced" which is very unsettling. I am finding that a lot of newer model 2019+ Chevy Blazer owners are struggling with the exact same temperature issue, even those with way fewer mileage than mine for example a person who just had 25K on theirs. This needs to be taken more seriously / addressed further by the manufacturer.
