24: Honda Odyssey
How could a minivan with a Honda badge be expensive to maintain? Well, the Odyssey has its problems with expensive repair costs. The unique thing about the Odyssey is that the van has remained a dominant force in the minivan segment for this long (via Autolist).
The downside of the Odyssey is that it has many defects that are expensive to repair. The transmission fails often in the first generation of the van, and there are also known issues with the valves. This is a common problem Honda has addressed under warranty. But for used models, this, unfortunately, won’t be the case.
