This includes some extended K models cars as well. Although this includes the smaller 3.3L it includes some Dodge Intrepids, Chrysler Concordes, Eagle Visions, etc.

You might be surprised. Some people drive them very hard since they aren't very fast. Also if your driving in hilly territory, they downshift a lot.

The other thing to take into account is how other engines offer in the same market faired. For example, the Windstar offered the 3.8L which some claim its a V6 version of the 5.0L with aluminum heads. Regardless where it is from, I know of quite a few cases of head gasket failure with the Ford 3.8L in the Minivans at around 60,000 miles. This was also the case in the Mustang and Taurus at around the same mileage.

Also (no offense to the 3.0L Mitsubishi fans) I have seen a few cases of oil leaks with the 3.0L Mitsubishi at low mileage and maybe one head gasket case. I haven't seen many with as high mileage as the 3.3L/3.8L.

I have seen head gasket failures in pretty much all offerings I4 offerings in the Caravan/Voyagers Chrysler or Mitsubishi design, but the 2.6L seemed to have them sooner than the 2.5L and the 2.4L is more consistent than the 2.5L is.

I have seen a few cases of engine failure in the 3.4L in GM 1997-2004 minivans due to intake manifold gaskets at around 70,000 miles.

I've heard of sludge problems with some of the older Sienna's but that was because the whole engine line was known for having that problem. I've heard of oil leaks in the Odessey engines. I think the old Nissan Quest/Mercury Villager 3.0L and 3.3L had some problems with the cam shaft or something.

The problem I have with your example is that I have seen so many different engines being offered in cars that do not inspire people to drive fast and they still have as many problems as the ones in models that are more likely to be driven harder.
