So I Received my cross bars from the dealer last week and just got around to installing them. I was rather shocked that they are all plastic and appear rather flimsy. They are not at all of the quality that I expect from Toyota. They are rated at 100 lbs. combined, but I am not even sure about that. In comparison the aluminum ones on my Infiniti were also rated at 100 lbs., but I routinely carried 2 kayaks and associated Yakima racks that probably totaled 130 lbs. without a worry. Judging by the many posts about seeking alternative racks my concerns have been expressed by many others. However, what I wonder if has anyone actually had the OEM cross bars fail on them? And if so what (and how much) where you carrying? It is possible they are stronger than they look.
