 All the Mazda's have a problem with the transmission where it feels like you got hit by another car. It's the transmission shifting. It only happens every few months, but they won't fix the problem. The gas mileage is lower than they say at 19 mpg with part highway and part in town. If it is all freeway, and you drive 60 or less, you can get 24 mpg. I got that once. Overall I love the van, but the gas is too expensive now, so I'm selling. No other problems have ever occurred, and I have 24,000 miles.
