I was told when I got my Murano in Oct. '03 that they were having problems/recalled the cross rails from the dealers do to a load bearing issue. The original cross bars were collapsing because of the wrong manuf. specs being used. I've checked every month since Oct. and yesterday they told me the updated units were finally available. If you got yours last month then I might assume they are the upgraded cross bars, but might be worth a call to verify. I only want to carry an extension ladder on occasion. I have no reason not to believe the dealer I bought the bars from since they could have sold me the old ones at anytime.
