NHTSA Complaint #11647903 — 2020 CHEVROLET BLAZER

Cooling ran would never shut off, 'Steering Assist Reduced Drive with Care', the smell of sweet syrup (coolant), and the temp gauge would not leave 'C'. All of this happened at once. Brought it in as it was subsequently throwing codes. Chevy Heiderbrecht dealership said that the radiator seal at 53k is completely eroded away and needs to be replaced. They said this is a very common issue with these cars (2020 Blazer/Original Owner), and looking online there is a plethora of people with the exact same issue (low mileage, complete radiator replacement due to seal going bad on upper driver side). This is insane, you spend 40k on a car, maintain it well, and the parts fail this prematurely with no available recall? Now I am stuck with an $1,800 bill with no legal recourse? I mean the dealership said it is a widely known issue, and GM has admitted that the seal is bad, but there's no consumer protection from this big of a company? Only thing covered under powertrain warranty is the thermostat (wow thanks GM!) Thanks for any help you can provide.
