They are built in the same factory with many of the same components, so I wouldn't expect too much of a difference. It's really hit and miss, and from what I have read a LOT of it has to do with ground wires not installed correctly. Personally I haven't had any issues, nor have many others.
These issues aren't limited to the Explorer, read up on Telluride/Palisade/Atlas/InsertSUVhere forums.
