I actually started out with a Chevy Traverse that I bought used from CarMax. It was a 2009, and unbeknownst to me at the time of purchase, 2009's had a major issue with the 3-5-R wave plate disintegrating in the transmission. GM even extended their warranty period to cover people who had the problem within 120k miles or 5 years.
Anyway, mine failed almost immediately, and was covered under warranty... four times in five months. On the fourth time I requested that we just be allowed to apply the money we had put into it toward purchasing something else. And that's how we ended up with the slightly used 2015 Explorer Sport. (Yes, the payments were higher, but well worth it to us after our bad experience with the Traverse.)
Our Traverse was the fully loaded "LTZ" model.
Pros with the Traverse:
* Softer feel on the open road.
* More amenities (power lift gate, DVD player, seat coolers.. that sort of thing)
* Slightly longer wheelbase (a little more room inside, and more towing stability).
* Roof rack holds up to 250 pounds.
* Trailer hitch tongue capacity was 600 pounds vs 500 pounds for the Ex.
* Doors don't swing as wide as the Explorer (easier to open in a tight lot).
Pros with the Explorer
* Stiffer suspension feels nicer around town, corners, etc. (The Traverse's softer suspension felt more like a boat sometimes.)
* Much more power. We love the EcoBoost engine.
* Much better looking.
* Driving it feels like the vehicle actually loves to drive.
* Seemingly more cargo area behind 3rd row.
* Better interior configuration despite slightly less room (2-3-2 in the Ex is better than 2-2-3 in the Traverse)
* Better backup cam.
* Better navigation system.
* Much better AWD/4WD and traction control system.
* Better gas mileage.
The 2015 Explorer Sport is a superior vehicle to the Traverse, in my opinion. I'm glad (now) that we had enough trouble with the Traverse that we were willing to cut our losses and move on.
Also, the Traverse just seemed a little too much like a minivan with SUV doors. And although ours had AWD, the 4WD of the Explorer really feels more capable. We wish the Explorer's roof rack were more sturdy, and kind of miss the power-lift rear gate, but overall much prefer the Explorer.
