Never had a problem with my Yakima system. After 8 years, it's still solid as a rock. I treat it well. I take it off during the winter months, no point in getting salt onto the threads. I have a Honda Odyssey so the size factor is similar to yours, and even at 5'-6" (I'll bet you're taller than I am), I have little trouble getting 3 bikes on and off the rack.
I once made the mistake of going through an ATM drive up window. The bike wasn't harmed, although the Yakima was. I had to buy one new mounting bracket. Otherwise, the system has been fine ever since.
