Perhaps someone else here will no more.

The folks that I know that have had Durango's over the years have liked them.

Dropped valve seats are usually fallout from running an engine low on coolant, coupled with an insert material spec problem..

What happens is that if the engine is low on coolant, it may run fine and show no overt signs of overheating because as long as the water pump is turning, the cylinder heads will be filled with coolant.

As soon as the engine is stopped and the water pump stops turning, the coolant drops below the cylinder head deck level, and the metal temperature in the valve bridge area skyrockets. If the valve bridge doesn’t eventually crack, the high temperatures may, depending on the insert material spec cause the inserts to fail in compressive yield. Essentially the hoop stresses induced exceed the yield stress capabilities of the insert, they collapse, loose the press fit in the cylinder head, and drop when the engine is restarted.

Insert material spec changes cam eliminate or at least mitigate this failure mode.

Typical engine design and development should include the FEA analysis and dyno tests to eliminate this failure.

High mileage doesn’t cause the failure, it’s the lack of cooling system maintenance and subsequent overheating on shutdown that often is a byproduct of high mileage.

My co-worker has an 06. Only issue it had was the radio and the exhaust manifolds.

Why not get another minivan? Drives better, better gas mileage, more roomy, better visibility.

I'd like to replace my 2000 Durango with a newer one, but really don't like the looks of the second gen Durango, so I'm waiting until the later models get down in price some. We just rolled over 150k on ours and will be trying to hit 200k before we do something with it. That might be in 8 years...

Two of my reps had Durangos back in the 2007-8 era - one was a 4.7L & the other was a Hemi, & my Michigan rep just got out of one from this generation as well just recently. As far as powertrain, none of theirs had any failures & they seemed like tough, solid vehicles. No suspension or steering issues either. Obviously they got rid of them before any major failures. My takeaway on them is I liked the way they looked (Chrysler aspens as well), but they were pretty ugly & plastic-ey on the interiors, and they were VERY rough riding & noisy & harsh as they go down the road. Way worse than even a Ram pickup. Personally, I'd stay away from them. Just bought my wife a 2013 Edge I picked up out in Vegas a month ago, but then it's not a 7 passenger vehicle. How about a Yukon? Hate to say it, but I know quite a few folks with these Suburban-Yukon type GM's that seem to go forever with little to no issues.

Those Durangos cost less than many of the other SUV's in this area. I looked at them quite seriously. The thing that turned me away was the concern about rust. It seems like those are a bit to rust prone. Rust is a significant threat here.

As already stated, mini offer far more value per dollar, especially in this area. Four wheel drives are VERY, VERY popular here and command a significantly higher price. Of course, many people need a 4x4 due to the climate!
