17: Dodge Grand Caravan
The original and arguably the most popular minivan to ever grace the automotive world is also expensive to fix. The Grand Caravan has one of the most stellar sales records of any minivan on the market (via Hot Cars).
However there are many reliability issues with the caravan, and many of these issues are expensive to repair. The transmission is the most common, and the timing chain is the second most common failure on the Grand Caravan.
