Cars that suffer from chronic head gasket problems are astonishingly expensive to keep running. Consumer Reports has put together a list of the worst offenders by analyzing data from its Annual Autos Survey. There are four Subaru models on the list, several luxury cars, and, surprisingly, everyone’s favorite Mazda roadster.
In simple terms, a head gasket is a part that ensures an engine’s combustion happens internally. It’s between the cylinder head and the engine block. Every car has at least one, and changing it is a time-consuming process that can cost over $1,000 depending on what you drive, the extent of the damage, and who you ask to fix it.
