So I have had a problem with excessive oil consumption in my car for the last year or so. I was told by Franklin Chevrolet of Statesboro that I could either pay over $5,000 for repairs or add oil between changes. I have constantly checked and added oil between changes since then.
I get a recall letter for this issue and call to make a service appointment. Franklin tells me that they already fixed the issue in my vehicle and that I can bring it in, but it will not be covered under this recall. They did NOT fix ANYTHING! This is not the first problem I have had with them. This is the absolute worst dealership to do business with!
