The Tribeca is not aging well. It's loose and rattly and coarse and rough-riding. The boxer engine has sufficient power but doesn't sound great. The navigation system is positioned too far away from both the driver and the passenger. The interior is cramped for both front-seat and middle-seat passengers, not to mention the extremely cramped third-row seat. There is absolutely no driving joy to be had here, utility is severely compromised, and it's not pretty, so all you're left with are Subaru reliability and the benefits of standard all-wheel drive. These are nice things to have, but there are way too many other seven-passenger crossovers that have not only those attributes but also some performance, some crispness, some ride quality, and some visual pizzazz.
Subaru has come up with winner after winner recently --witness the Impreza, the Forester, and the new Legacy/Outback -- but it's time for them to completely revamp the Tribeca, which is simply no longer in the game.
