Sampson, sounds like a bunt out bulb, which will need changed.
If you feel comfortable doing it yourself. Basically three screws, and you have to pull one plastic fastener from the fascia (bumper) and pull the bumper back a bit, and pull the assembly out. I believe it is in the manual, not bad to do. I will post a link to tell or show you how to do it. Press the helpful button
I am currently having the same problem with my 2006 Buick lacrosse I changed water pump, thermostat , radiator, radiator car bled it add dex coolant but it's still running hot...got it tested for the psi n it came bak good reading
I strongly recommend you take it back to the dealer and ask for help. If it is something they damaged, and you have another shop repair it, the dealer is then off the hook for responsibility. The problem could be a blend door under the dash, or the heater core may not be getting proper coolant flow.
