22: Subaru Outback
The Outback is one of the most popular wagons ever to grace the automotive world. In recent years, owning a Subaru has become a sort of status symbol. But with a status symbol car, there is also the price tag of high repairs (via Hot Cars).
The AWD system in the Outback is not bulletproof and older models are also subject to head gasket failures. That’s not to say the Outback is a bad ride, but you will spend a fair amount of money to keep it going.
