What minivan has the fewest problems?

There's no single definitive answer to which minivan has the fewest problems, as reliability varies year to year, and different sources use different methodologies. However, consistently ranking highly in reliability surveys are the Toyota Sienna and the Honda Odyssey.

Both consistently receive good marks from organizations like Consumer Reports and J.D. Power. However, even within a given model year, individual experiences can differ. It's always best to check specific year-to-year reliability data from those sources before making a purchase decision.
