Well, this is my experience: We bought our 2007 Tribeca new from the dealer in 2007 - since then? Well it consumes more than a quart of oil a month. Also, for the second time since we've owned it it needed the timing chain serviced (first was under warranty, thank God). This time I had done the oil change in May, in July it was down 4 quarts! Amazing, and this time there was no factory warranty to back it up. Do yourself a favor and get something else.
Interior design is really good, comparable to a car double the price.
After we traded it in this past weekend we found out (through a extended friends) that the engine is too big for the transmission in the car and it can't handle it. Not sure if that was our issue, but once it started burning tons of oil we got rid of it - quickly
